Description
Technical Field
The invention belongs to the technical field of heat exchangers, and particularly relates to a cooler and a cooler system with double media, double flow paths and a flow equalizing structure.
Background
With the increasing attention of the whole society to carbon peak and carbon neutralization, more and more large wind power generators are developed, and particularly, the direct-drive wind power generators are becoming larger. Aiming at the problem of heat dissipation and cooling of a direct-drive wind driven generator, a common solution is to arrange a plurality of air-water coolers on the direct-drive wind driven generator to cool a plurality of winding coils. For each air-water cooler, it is necessary to connect the inlet and outlet pipes, and also to have an enormous size of inlet and outlet manifolds. The above solution results in a cooling system that requires multiple connections, resulting in a very complex cooling system, a large cooling system size, and a very high reliability requirement for the cooling system.
For the above reasons, it is important to design a cooling system with simple and reliable connection.
As shown in fig. 1, a schematic diagram of a cooling system of a conventional direct-drive generator is shown. The cooling system comprises a liquid inlet manifold 8, a liquid outlet manifold 9, a liquid inlet connecting pipe 6, an air-water cooler 10 and a liquid outlet connecting pipe 7. The cooling system of the traditional direct-drive generator has the following characteristics:
(1) In the entire cooling system, since the plurality of heat generating windings are spatially separated, the plurality of air-water coolers 10 are required to cool the plurality of heat generating windings, respectively, and the plurality of air-water coolers 10 are required. At least one inlet connection pipe 6 and outlet connection pipe 7 are required for each air-water cooler 10, resulting in a complicated connection of the cooling system.
(2) The liquid inlet manifold 8 and the liquid outlet manifold 9 are arranged around the main shaft of the direct-drive wind driven generator, and because of the huge size, a large installation space is required, and the vibration requirement on a generator cooling system is high.

At least two of the foregoing coolers are included, wherein:
The two adjacent coolers are communicated through two connecting pipes, and a first liquid outlet and a second liquid outlet of one cooler are respectively communicated with a first liquid inlet and a second liquid inlet of the other cooler through one connecting pipe;

Detailed Description
The invention is further described in connection with the accompanying drawings, but the scope of protection claimed is not limited to this.
Fig. 2 is a schematic layout of a cooling system for a heat generating winding of a direct-drive wind turbine according to the present embodiment. The cooler system at least comprises two novel coolers 2 and two connecting pipes 3, and in the implementation process, the liquid inlet pipe 1, the liquid outlet pipe 5 and the plug 4 can be used or not used in the cooler system according to the requirements.
As shown in fig. 3, a schematic diagram of the novel cooler 2 designed in this embodiment is shown. The novel cooler 2 comprises at least one liquid inlet side groove plate assembly 21, at least one core assembly 22, at least one flow equalizing groove plate assembly 23, at least one fluid diversion groove plate assembly 24 and at least one liquid outlet side groove plate assembly 25. The above components are welded together to form the new cooler 2.
As shown in fig. 6, the core assembly 22 in the cooler 2 uses the same components as the core assembly in a conventional plate-fin cooler, which differs from the conventional plate-fin cooler core assembly in that: in a conventional plate-fin type wick assembly, the first medium has two channels on the flow side, and the first medium flows in opposite directions in the two channels after undergoing 180 DEG reversing, but the second medium forms cross-flow heat exchange with the two channels through two independent channels, which respectively flow with the first medium. As can be seen from fig. 1, the two channels of the first medium flow are in the same plane, and the two channels of the second medium flow intersect with the two first medium flow channels in the plane, respectively, to form a cross flow.
By comparison, in the novel cooler 2, the core assembly 22 has a first channel (indicated by the letter T1 in fig. 6) and a second channel (indicated by the letter T2 in fig. 6) therein, together with two first media flow channels (indicated by the letter a and the arrow in fig. 6), which are in an up-down positional relationship in fig. 6, i.e., which are not in the same plane, which is a significant difference from conventional core assemblies. The flow of the first medium is in opposite directions in the first and second channels of the wick assembly 22. The second medium (indicated by letter B and arrow in fig. 6) flows within the third channels (indicated by letter T3 in fig. 6) of the wick assembly 22, and it can be seen that the third channels (only one) pass through both the first and second channels, which is also one of the features that is different from the conventional wick assembly. The flow direction of the first medium within the wick assembly 22 is perpendicular to the flow direction of the second medium within the third channel, creating cross-flow heat exchange.
As shown in fig. 4, the flow equalizing slot plate assembly 23 of the novel cooler 2 is provided with flow equalizing holes 26, and the function of the holes is to make the flow of the first medium in all the coolers 2 connected in parallel substantially equal, and the principle is that: as shown in fig. 4 and 6, when the flow equalization hole 26 is formed in the flow equalization tank plate assembly 23, the total flow area of the flow equalization hole 26 in each cooler 2 is small relative to the single-side flow area of a certain cooler 2 (for example, the flow area of the liquid inlet side tank plate assembly 21 in fig. 3), and a large flow resistance (equivalent to a "throat" in the system) is generated when the first medium flows through the flow equalization hole 26 in the cooler 2, the flow resistance of the first medium in the liquid inlet pipe 1, the connection pipe 3 and the liquid inlet side tank plate assembly 21 is relatively small, so that the first medium can uniformly flow into the first channel of the cooler 2 when the plurality of cooler core assemblies 2 are connected in parallel.
As shown in fig. 2 and 5, in the cooling system, the liquid inlet sides of the coolers 2 are connected together by using the connecting pipe 3, and the liquid outlet sides of the coolers 2 are connected together by using the connecting pipe 3.
As shown in fig. 5 and 6, the flow path of the first medium is as follows: the first medium enters the cooler system from the liquid inlet pipe 1, the liquid inlet sides of all coolers 2 are mutually connected together due to the existence of the connecting pipes 3, the first medium fills the liquid inlet side groove plate assemblies 21 of all coolers 2 and the connecting pipes 3, the first medium enters first channels in the core assemblies 22 of all coolers 2 in parallel, the first medium respectively reaches the flow equalizing groove plate assemblies 23 of the coolers 2, the first medium respectively passes through the flow equalizing holes 26 of the flow equalizing groove plate assemblies 23, the first medium respectively reaches the fluid diversion groove plate assemblies 24 of the coolers 2, the first medium is completely diverted by 180 degrees, the first medium respectively enters the second channels of the core assemblies 22 of the coolers 2, the first medium respectively reaches the liquid outlet side groove plate assemblies 25 of the coolers 2, the first medium is mixed together at the liquid outlet sides of the coolers 2 due to the fact that the liquid outlet sides of all coolers 2 are connected together by the connecting pipes 3, and the first medium flows out of the coolers at the liquid outlet pipe 5. The second medium passes through the wick assembly 22 in a sequence from below the wick assembly 22 or passes through the wick assembly 22 in a sequence from top to bottom in a flow direction perpendicular to the flow direction of the first medium.
In this embodiment, a cooler and a cooler system are designed, and the above embodiments are not intended to limit the scope of the present invention, and all modifications, or equivalent substitutions made on the basis of the technical solution of the present invention should fall within the scope of the present invention.
