The specific embodiment
Describe embodiment of the present utility model below in detail, the example of embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
First by reference to the accompanying drawings specifically describe the air conditioner electric control case assembly 100 according to the utility model embodiment below.
As shown in Figures 1 to 8, according to the air conditioner electric control case assembly 100 of the utility model embodiment, comprise: electric-controlled box 10, substrate 20 and radiator 30.Particularly, electric-controlled box 10 has heater element, and substrate 20 is connected with heater element (not shown), and radiator 30 comprises heat sink 31 and the refrigerant pipe 32 being connected with heat sink 31, and heat sink 31 is connected with substrate 20.
Thus, according to the air conditioner electric control case assembly 100 of the utility model embodiment, by heat sink 31 is connected with substrate 20, substrate 20 is connected with heater element, refrigerant pipe 32 can indirectly be connected and realize exchange heat with heater element, thereby realization is cooling to heater element, radiator 30 cooling effects of this structure are better and easy to assembly, and unloading process is simple, only need heat sink 31 is separated with heater element with substrate 20 or substrate 20, can make radiator 30 separated with electric-controlled box 10, easy accessibility and can not damage electric-controlled box 10 or radiator 30.
Heat sink 31 and refrigerant pipe 32 are connected to form the radiator 30 of integral type, and radiator 30 links together by heat sink 31 and substrate 20.Now, can mutual transferring heat between refrigerant pipe 32 and heat sink 31, heat sink 31 and substrate, substrate 20 and heater element.Thus, when temperature of heating elements is higher, heater element can carry out heat exchange by the lower refrigerant pipe 32 of substrate 20 and heat sink 31 and temperature, so that heater element is lowered the temperature.In order to improve heat exchange efficiency, substrate 20 and heat sink 31 can adopt metal material, aluminium sheet for example, and similarly, refrigerant pipe 32 can adopt copper pipe or aluminum pipe.
In addition, refrigerant pipe 32 is connected to form a loop with the refrigeration system of air-conditioning, and when the cold-producing medium in refrigeration system flows through refrigerant pipe 32, cold-producing medium can absorb the heat that electric-controlled box 10 passes to radiator 30, so that electric-controlled box 10 is lowered the temperature.And along with cold-producing medium circulating in refrigeration system constantly, the heat of the absorption radiator 30 that refrigerant pipe 32 can be lasting.Therefore the heater element of electric-controlled box 10 can remain on a lower temperature for a long time, the good heat dissipation effect of electric-controlled box 10, and radiating efficiency is high.Because electric-controlled box 10 is being controlled the operation of air-conditioning, the lifting of electric-controlled box 10 radiating efficiencys can make the working order of air-conditioning improve, thereby improves the refrigerating efficiency of air-conditioning.In addition, electric-controlled box 10 also can make the compressor of air-conditioning carry out high frequency running, strengthens the refrigeration of air-conditioning.
Refrigerant pipe 32 is in the not restriction of mounting means of heat sink 31, and alternatively, in an embodiment of the present utility model, the upper surface of heat sink 31 is connected with the lower surface of substrate 20, and the lower surface of heat sink 31 is provided with the groove 311 that holds refrigerant pipe 32.Further, refrigerant pipe 32 is connected in groove 311.
Particularly, as shown in Figure 2, substrate 20 forms rectangular slab substantially, and the upper surface of substrate 20 is connected with the heater element of electric-controlled box 10, and heat sink 31 also forms rectangular slab, and substrate 20 is connected with heat sink 31.As shown in Figure 3, the lower surface of heat sink 31 is provided with the groove 311 of adaptive refrigerant pipe 32, and refrigerant pipe 32 is pressed in groove 311, and refrigerant pipe 32 and heat sink 31 complete assembling, or also refrigerant pipe 32 can be inserted in groove 311, to refrigerant pipe 32 and heat sink 31 compressions, can complete assembling.Thus, refrigerant pipe 32 is stuck in groove 311, and refrigerant pipe 32 is simple with the fit system of heat sink 31.
