And in the existing convertible frequency air-conditioner, when cold-producing medium was got back to compressor by evaporator, its cold-producing medium also had certain cryogenic effect, can be used to chip is lowered the temperature, and there is no this kind device in the present convertible frequency air-conditioner.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of convertible frequency air-conditioner chip heat radiator, it can fast reducing convertible frequency air-conditioner chip temperature during operation, in the useful life of improving chip, reduced simultaneously volume and the cost of heat abstractor.
Technology solution of the present utility model is as follows:
A kind of convertible frequency air-conditioner chip heat radiator, it includes one or more flat tubes and two collector tubes, wherein, flat tube is fixed on the chip, be provided with one or more opening in the flat tube, be connected with cold-producing medium in the opening, flat tube is arranged between two collector tubes along the length direction of collector tube, and the opening two ends are connected with two collector tubes respectively; One in two collector tubes is provided with import, and another is provided with outlet.
Described flat tube directly contacts with chip, and flat tube is that Heat Conduction Material is made, and it is made for copper metal material or aluminum metallic material.
The two ends of described flat tube are welded and fixed together with two collector tubes respectively.
, described opening becomes yi word pattern to arrange.
The beneficial effects of the utility model are:
(1), the utility model is arranged on evaporator to be back between the compressor, import is linked to each other with tube connector, outlet links to each other with the return duct of compressor, and the flat tube wall is fixed on the chip, after returning through tube connector by evaporator, cold-producing medium enters the collector tube of top, enter flat tube, because the temperature of the cold-producing medium that refluxes is low, and flat tube directly contacts with chip again, colder flow of refrigerant is arranged in the flat tube, so that the temperature of the temperature of chip and cold-producing medium is carried out heat exchange, the temperature of fast reducing chip generally can be reduced to chip temperature about 20 ° by 80 °, its successful, improve the useful life of chip, simultaneously, had energy-conservation effect.
(2), the utility model is simple in structure, volume is little, has reduced cost of manufacture, simultaneously, also further can dwindle the overall volume of air-conditioning, reduces air-conditioning taking the space.
