Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Fig. 1 to 5, the invention provides a kind of heat abstractor of electric elements, comprise mainboard 1 and cooling system 4, wherein mainboard is provided with module 11, the bottom of module 11 protrudes from mainboard, namely there is the ledge protruding from mainboard bottom surface, mainboard 1 is placed in installing plate 2, be bolted, installing plate 2 is provided with the first blank portion 21 suitable with the ledge of module 11, the quantity in the first blank portion is equal with the quantity of the module 11 on mainboard 1, by arranging installing plate 2, can make mainboard fixation.
This module can be electric elements module, the electric elements namely on mainboard itself, also can be radiating module, the radiating module namely arranged under electric elements.
And be that the cooling system 4 that mainboard dispels the heat comprises heat-exchanger rig 42 and radiator, heat-exchanger rig 42 is embedded in radiator, radiator is provided with the heat-exchanger rig passage suitable with heat-exchanger rig 42, wherein, heat-exchanger rig 42 is embedded in radiator, first aspect can make heat-exchanger rig fully contact with heat radiation, increases heat exchange area, improves heat exchange efficiency; Second aspect can reduce the volume of cooling system, reduces the space that it takies, the low impact on refrigeration system of a step-down of going forward side by side; The third aspect effectively can fix heat-exchanger rig makes it firm.
Preferably, radiator is divided into the first fin 41 and the second fin 43, heat-exchanger rig passage is formed after the groove 412 on the first fin and the groove 431 on the second fin combine, namely by the first fin 41 and the second fin 43, micro-channel heat exchanger is wrapped in wherein, wherein, the first fin 41 and the second fin 43 can adopt of the same race or not same material.
As shown in Figure 5, heat-exchanger rig 42 is micro-channel heat exchanger, micro-channel heat exchanger adopts flat-shaped structure, volume can be reduced further, reduce cooling system taken up space, wherein the shape of heat-exchanger rig passage and micro-channel heat exchanger is suitable, cold-producing medium in refrigeration systems carries out heat exchange between micro-channel heat exchanger and the first fin 41, thus arrive the effect of lowering the temperature to the module 11 on mainboard 1, the efficiency adopting cold-producing medium to lower the temperature to module 11 will be much higher than air-cooled radiator, and reduces energy consumption.
Wherein, radiator is also provided with the depressed part 411 suitable with the ledge of module 11; in the prior art; usually because the problem of level of processing and installation often can cause the contact of module 11 and radiator to be not very abundant between module 11 and heat sink contact surface; and by arranging depressed part 411 on a heat sink, can make to make module 11 match with depressed part 411 very accurately in the process of installing, make both fully contacts; increase heat exchange area, strengthen heat exchange efficiency.
Further, heat conduction colloid can be scribbled in depressed part 411, as thermal grease or heat conductive rubber etc., be allowed to condition in depressed part 411 and form very thin one deck, even if the mounting plane degree like this between module 11 and heat abstractor is bad or to install be not very just to ensure that between module 11 on mainboard 1 and radiator, heat trnasfer is smooth yet, be convenient to module 11 dispel the heat, reach the effect of lowering the temperature rapidly to the module 11 on mainboard 1.
Wherein, this depressed part 411 is arranged on the first fin 41, and with the side opposing with the groove on the first fin, namely for the first fin, its both sides are equipped with groove, wherein side is the depressed part 411 suitable with module, and side is join the groove 412 on the first applicable fin with heat-exchanger rig in addition.And the groove 431 the second fin 43 is only provided with on the second fin suitable with heat-exchanger rig.
One piece of uniform sponge 3 of thickness can also be provided with between installing plate 2 and radiator, sponge is provided with the second blank portion 31 suitable with the ledge of module 11, and the module on mainboard 1 is contacted with the depressed part 411 on radiator through the first blank portion 21 on installing plate 2 and the blank portion 31 of second on sponge 3 are rear.When radiator and installing plate 2 are fixed together, sponge 3 seals between, prevent from the steam below installing plate 2 from contacting with module 11 producing condensed water that (the temperature difference of installing plate 2 upper air temperature and module 11 is little, can not condensed water be produced) while, can ensure that again module 11 and radiator contact preferably.
Wherein, installing plate 2 can be a part for cooling system, fixing in order to fixedly to wait mainboard of lowering the temperature with radiator.Further, installing plate 2 and the first fin 41 are fixed.
As shown in Figure 5, micro-channel heat exchanger comprises left header, right header, middle flat tube and the first Cu-Al connecting pipe and the second Cu-Al connecting pipe, wherein, first Cu-Al connecting pipe is all connected with right header with the second Cu-Al connecting pipe, in the middle of right header, there is one piece of dividing plate to be divided into two chambeies, be communicated with the second Cu-Al connecting pipe with the first Cu-Al connecting pipe respectively, cold-producing medium cannot be mixed in right header, middle flat tube is arranged on a left side, between right header, three is connected, its operation principle is, during refrigerant heat exchanger, first right header is entered from the first Cu-Al connecting pipe, then enter in left header by flat tube, flat tube in the middle of cold-producing medium flows into from left header again, then enter into the another one chamber of right header and finally enter refrigeration system from the second Cu-Al connecting pipe.
In the present embodiment, radiator, micro-channel heat exchanger and installing plate 2 etc. is all flat, can ensure that cooling system takes up room so little, reduce the impact on air-conditioning system.
Present invention also offers a kind of air-conditioner, comprise the heat abstractor of electric elements as above.
Preferably, cooling system is arranged between the port of export of condenser and the entrance point of compressor, and the cold-producing medium of refrigeration system enters compressor after heat-exchanger rig.
By the radiator on the heat abstractor of the electric elements in air-conditioning is provided with the depressed part suitable with the module on mainboard, and make fully to contact between mainboard module with heat sink contact surface, improve heat transmission, thus improve performance and the service life of air-conditioning further.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
