Utility model content
The purpose of this utility model is directed to the deficiencies in the prior art, there is provided a kind of radiating knot of air-conditioning frequency conversion drive module Structure, can carry out heat exchange, so as to quickly reduce on the basis of wind-cooling heat dissipating using condensed refrigerant and frequency conversion drive module The temperature of frequency conversion drive module, improves radiating efficiency and stability.Meanwhile, can also pass through when system refrigerant circulation is not enough Wind-cooling heat dissipating reduces frequency conversion drive module temperature, it is ensured that air conditioning high efficiency runs.
The technical solution of the utility model is:
A kind of radiator structure of air-conditioning frequency conversion drive module, including installation of fitting successively substrate, fixed plate and heat sink, Air-conditioning frequency conversion drive module is installed on the non-binding face of the substrate;Coolant conduits are embedded in the fixed plate;The refrigerant Conduit is connected with the refrigerant-cycle systems of air-conditioning, can carry out heat exchange using refrigerant;The non-binding face of the heat sink It is provided with multiple fins raised.
Further, the substrate is lamellar, and two surfaces are plane.
Further, the fixed plate is provided with two parallel grooves;The section of the groove is circular arc, and be open direction The side of the heat sink, can be embedded coolant conduits.
Further, the groove is 1/2 ~ 3/4 circular arc, and diameter is adapted with the diameter of the coolant conduits, makes institute Stating coolant conduits closely can be embedded in wherein, and the part that the coolant conduits are higher by the groove is flattened, and make refrigeration Agent conduit is flush with fixed plate surface.
Further, the coolant conduits are U-shaped, and its elbow part is placed in outside fixed plate.
Further, the fixed plate is identical with the size of heat sink, and respectively less than described substrate size.
Further, the substrate, between fixed plate and heat sink by screw connection, and uniformly applied on each contact surface There is heat-conducting silicone grease.
Further, heat-conducting silicone grease is scribbled between the coolant conduits and the groove inner surface.
Further, heat-conducting silicone grease is scribbled between the air-conditioning frequency conversion drive module and substrate.
Further, the coolant conduits are connected between the outdoor heat exchanger of air-conditioning and subcooler.
The beneficial effects of the utility model:
The utility model is reasonable in design, simple structure, and installation and removal are convenient, can be provided simultaneously with two kinds of radiating modes, have Effect improves the radiating effect of air-conditioning frequency conversion drive module, and can avoid producing influence to the operational efficiency on unit.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As Figure 1-3.
A kind of radiator structure of air-conditioning frequency conversion drive module, including the substrate 1 of installation of fitting successively, fixed plate 4 and radiating Plate 6.The substrate 1 is lamellar, and two surfaces are plane.Air-conditioning frequency conversion drive is installed on the non-binding face of the substrate 1 Module.The fixed plate 3 is slightly thicker than the substrate 1, which is provided with two parallel grooves.The section of the groove is circular arc. Preferably, the circular arc can be 1/2 ~ 3/4 circular arc, and be open towards the side of the heat sink 6.The diameter of the groove and refrigeration The diameter of agent conduit 4 is adapted, and the coolant conduits 4 is closely embedded in wherein.Meanwhile, the coolant conduits 4 are high The part for going out the groove is driven plain, and the coolant conduits 4 is flush with the surface of the fixed plate 3, described solid to make Fixed board 3 can fully fit with the heat sink 5.The coolant conduits 4 are connected with the refrigerant-cycle systems of air-conditioning, can Using refrigerant heat exchange is carried out with the air-conditioning frequency conversion drive module.Generally, the coolant conduits 4 are connected to the room of air-conditioning Between external heat exchanger and subcooler, the liquid refrigerants of the medium temperature and medium pressure of outflow outdoor heat exchanger is set to flow through the coolant conduits 4, By heat exchange, the air-conditioning frequency conversion drive module 2 is set to be lowered the temperature.The coolant conduits 4 are U-shaped, and its heel splits Outside fixed plate, installation operation can be facilitated.The non-binding face of the heat sink 5 is provided with multiple fins projections, can strengthen Its air cooling effect.
The fixed plate 3 is identical with the size of heat sink 5, and respectively less than described substrate 1 size, can conveniently install, and Ensure radiating effect.
The substrate 1, fixed plate 3 and heat sink 5 are made by sheet metal, and are closely connected by by screw, really Protect good heat conductive each other.Meanwhile, on each contact surface between the substrate 1, fixed plate 3 and heat sink 5, the system Heat conduction is scribbled between cryogen conduit 4 and the groove inner surface, and between the air-conditioning frequency conversion drive module 2 and substrate 1 Silicone grease, is further ensured that heat-conductive characteristic.
When using, refrigerant of the present utility model can be flowed through by the refrigerant in low temperature in air conditioner cooling cycle system Conduit, carries out heat exchange and air-conditioning frequency conversion drive module is obtained radiating and cooling with air-conditioning frequency conversion drive module.Meanwhile, it is described to dissipate Detent projection on hot plate can increase air contact area, enhance wind-cooling heat dissipating ability, so as to further improve become to air-conditioning The radiating effect of frequency drive module.More have, when air conditioner refrigerating circulation is weaker, radiating and cooling can be carried out separately through heat sink, Ensure air-conditioning frequency conversion drive module normal work.
The utility model is not directed to partly same as the prior art or can be realized using prior art.
