(1) The upper part of the pushed-in cooler core cannot be completely sealed, and even if the welding quality is fine, its parallelism requirements cannot be guaranteed. The gasket is also placed together when the cooler core is pushed in, and it is easy to fall off and break without pressing. device, the hot air flows through the contact surface gap at high speed, but cannot completely pass through the cooler core, which affects its cooling effect.

(2) Most of the cooler cores are made of copper tubes and copper sheets, which are large in size and weight. The volume generally exceeds 1000*600*400mm3, and the weight is over 950kg. Due to the restrictions of self-weight and installation ports during installation, it is easy to Inclined, long installation time, difficult to adjust.

(3) The cylinder is designed as an integrated structure, which is not conducive to the internal structure of the cylinder and the installation and maintenance of the cooler core.

(4) The cylinder has a circular structure, the cooler core is square, and the cooler core is installed horizontally inside the cylinder. The gap between the heat sink and the cylinder wall is relatively large, and some hot air passes through the gap without being fully heated with the coolant. Exchange, low cooling efficiency.

(5) The commonly used cooler core weighs more than 950 kg. It is in a suspended state without support in the cylinder. It is prone to deformation under the action of its own weight and air pressure, which may damage the cylinder and affect the service life of the equipment.

(6) Due to the heavy weight of the cooler core, it is extremely inconvenient to install and adjust.
