Thermocouple 22 is a known tip assemblies, when it is switched on, itself promptly produces heat exchange action, wherein a side will produce heat energy, relatively in addition the side then produces the temperature difference and forms low temperature, so one of the utility model thermocouple 22 low temperature side contacts and give combination with cold plate 24, will condense into water droplet when the moisture of body 10 inside, case storehouse contacts the cold plate 24 of low temperature, through concentrating water droplet to discharge, can reach the moistureproof purpose of dehumidifying; Make thermocouple 22 form one of the high temperature side again and then contact with radiating fin 25, so that the two heat pipe 28 conducts to case storehouse body 10 outer radiating subassemblies 27 and does further pressure and disperse by it with heat energy by heat-conducting plate 23.
These heat-conducting plate 23 4 corners and centre are formed with fixing hole 231,232 respectively, set up screw rod 233,234 therebetween separately, can divide to supply and radiating fin 25 and cold plate 24 corresponding combinations; Heat-conducting plate 23 lateral surfaces are formed with the groove 230 of several semi-circular cross-section again, for ccontaining heat pipe 28, constitute bigger contact area simultaneously.
This cold plate 24 constitutes (as: aluminium) for the metal material that possesses thermal conduction characteristic, its central upper-lower position is formed with fixing hole 240 respectively, run through for screw rod 234, and mutually combine by thermal insulation barriers 26 and heat-conducting plate 23, this thermal insulation barriers 26 is elastomeric material (as the sponge) formation by non-heat conduction, its shape roughly cooperates wall contour shape within the case 50, its central authorities are formed with the notch 260 corresponding to thermocouple 22 again, four corners and notch 260 are formed with perforation 261 up and down respectively again, 262, its middle punch 261 is the combined structure that cooperates on the case 50, boring a hole again 262 passes for screw rods 234, and thermal insulation barriers 26 act on prevent heat-conducting plate 23 thermal energy conduction to cold plate 24.
Radiating fin 25 lateral surfaces are formed with most fin ribs 251, to increase area of dissipation, then be formed with the groove 250 of some semi-circular sections again on its medial surface, for being nested with heat pipe 28, and the contact area bigger with its formation, when radiating fin 25 and heat-conducting plate 23 relative in conjunction with after, this can press from both sides an end of pulling in each heat pipe 28.Radiating fin 25 another preferred embodiments see also Fig. 3 again, have bigger area of dissipation with the radiating fin 25 of this prismatic shapes, can effectively promote radiating efficiency.
See also Fig. 1 and Fig. 2, the hollow tube of heat pipe 28 for constituting by thermal conductive metallic material, it holds system to combine with radiating subassembly 27 in addition.
And for further strengthening radiating effect, radiating subassembly 27 can further be provided with a fan 29, so that each fin 270 is carried out forced heat radiation, and be fan attachment 29, aforementioned two stators 271 have extended to form lug 273 in relative the same side, be formed with fixing hole 274 on the lug 273, can supply fan attachment 29 (referring to Fig. 1).
Again first, the mat woven of fine bamboo strips two housings 51,52 are formed with relative semicircle orifice 516,526 on the same sidewall of correspondence, wear heat pipe 28 in the semicircle orifice 516,526.
Please cooperate and consult Fig. 4, Fig. 5, first housing, 51 bottoms systems is the water collecting part 513 of funnel-form, and water collecting part 513 bottoms also are formed with outlet pipe 514, and outlet pipe 514 can external aqueduct 515, for being connected with the discharge pipe line 101 of case storehouse body 10 internal preset.Case storehouse body 10 is provided with a fire line absorbent wool 104 in the place, bottom of corresponding discharge pipe line 101 ends again, concentrate by the converted water droplet of case storehouse body 10 inner moisture and in the 10 outside natural evaporations of case storehouse body to take in, absorbent wool 104 is placed in the wire netting dish 105 again, and wire netting dish 105 is fixed to body 10 bottoms, case storehouse again.
As for being that cable pipeline 102,103 by case storehouse body 10 internal preset is online to constitute between humidity sensor 30, control panel 40 and the Dehumidifying element 20, cable pipeline 102,103 is directly to be arranged in the concrete layer 13 of case storehouse body 10 with cable.
Can find out detailed construction operation principle of the present utility model by above-mentioned explanation, below further analyze course of action:
As shown in Figure 4, the Dehumidifying element 20 of body 10 inside, case storehouse is by humidity sensor 30 detecting humidity inside situations, through with control panel 40 on the condition set determine whether to start Dehumidifying element 20 after relatively.
After starting Dehumidifying element 20, its heat exchanger assembly 21 that is positioned at body 10 inside, case storehouse will make its thermocouple 22 energisings, and make cold plate 24 surfaces produce low temperature, when moisture condensation by contact plate 24 surface of body 10 inside, case storehouse, to be condensed into water droplet and by the aqueduct 515 of case 50 bottom connections beyond discharge pipe line 101 is expelled to case storehouse body 10, and reach the moistureproof purpose of dehumidifying.The heat energy that produces relatively as for thermocouple 22 other sides will conduct to radiating fin 25 and the heat pipe of the two 28 by heat-conducting plate 23, deliver to case storehouse body 10 outer radiating subassemblies 27 via heat pipe 28 again and utilize fan 29 to be forced to disperse.
Can find out one of the utility model embodiment concrete structure kenel and working method thereof by above-mentioned explanation, and for example shown in Figure 6, then be two of the utility model embodiment, it is roughly the same with one of embodiment that it forms structure, difference is in the laying kenel in Dehumidifying element 20, with regard to one of embodiment, the heat exchanger assembly 21 of its Dehumidifying element 20 and radiating subassembly 27 are to be divided into inside and outside the case storehouse body 10 with parallel direction; And embodiment second consider the principle that heat energy makes progress naturally, heat exchanger assembly 21 and radiating subassembly 27 are divided into inside and outside the case storehouse body 10 with vertical direction, by this can its radiating efficiency of more effective raising, and further strengthen its dehumidifying effect.
From the above, the utility model mainly solves the moisture issues in safety box (storehouse) by heat exchange principle with this, it can effectively overcome safety box storehouse inner moisture and may destroy the problem that vital document is hidden thing, and dehumidification function be finished automatically under the prerequisite that does not influence safety box library structure intensity.
The utility model also can be used for other and similarly installs.
