Refrigerant temperature after heat exchanger 40 reduces.Refrigerant after temperature reduces enters refrigerant radiating module 60, in refrigerant radiating module 60
The middle lower refrigerant of temperature takes away the calorific value in automatically controlled component, completes the cooling to automatically controlled component, and then refrigerant passes through
Enter outdoor heat exchanger 20 after the throttling cooling of restricting element 30；Alternatively, the refrigerant after temperature reduces enters restricting element 30, pass through
Enter refrigerant radiating module 60, the lower refrigerant band of temperature in refrigerant radiating module 60 after crossing the throttling cooling of restricting element 30
The calorific value in automatically controlled component is walked, completes the cooling to automatically controlled component, then refrigerant enters outdoor heat exchanger 20.Refrigerant exists
Heat absorption is evaporated in outdoor heat exchanger 20, the refrigerant come out from outdoor heat exchanger 20 eventually passes back to compressor by four-way valve
10, compression process is completed in compressor 10, compressed refrigerant is discharged from the exhaust outlet of compressor 10, so far completes to heat
One circulation of journey.

Pipe 61 penetrates the automatically controlled component that after the electric-controlled box 50 of sealing and calorific value is big and directly contacts, so that the low temperature refrigerant of flowing is direct
Automatically controlled component is cooled down, at the same time it can also the air of coolant seal, and then cools down other components, it is ensured that automatically controlled component
Reliability at high temperature.
Optionally, as shown in figure 16, heat sink 51 can be equipped on automatically controlled component, heat-dissipating pipe 61 and heat sink 51 paste
It closes, for example, heat sink 51 can be aluminum substrate, so as to increasing heat radiation area, enhancing heat dissipation effect.
Certainly, heat-dissipating pipe 61 can be contacted with the inner wall of cavity.For example, electric-controlled box 50 is two layers, outer layer is by heat-barrier material
It is made, internal layer is made of easy Heat Conduction Material, after heat-dissipating pipe 61 penetrates in electric-controlled box 50, is close to the internal layer of electric-controlled box 50, thus right
Internal layer and the air of sealing are cooled down, and internal layer and air after cooling again cool down the automatically controlled component of fever.Here,
The air contact that heat-dissipating pipe 61 a part of can be embedded in internal layer, a part and electric-controlled box 50；Alternatively, heat-dissipating pipe 61 can also be set
In the inside of internal layer, completely and inner layer contacts, for example, as illustrated in fig. 7 and fig. 10, cavity includes lower box body 52 and upper cover 53, on
Lid 53 covers lower box body 52, and heat-dissipating pipe 61 is embedded in upper cover 53.
Wherein, the trend of heat-dissipating pipe 61 can be through a surface of internal layer or multiple surfaces.It is appreciated that heat dissipation
When pipe 61 passes through a surface of internal layer, it may be that close to that biggish surface of calorific value of automatically controlled component.
Optionally, as shown in figure 13, heat-dissipating pipe 61 is configured to " u "-shaped, for example, heat-dissipating pipe 61 penetrates closed electric-controlled box
50 and the big automatically controlled component of calorific value directly contact, the low temperature refrigerant in pipeline absorbs the heat of automatically controlled component, makes automatically controlled
The temperature of component reduces, and by the path of a U-shaped, is then pierced by electric-controlled box 50.Heat-dissipating pipe 61 inside electric-controlled box 50 can
With there are many trends, for example, heat-dissipating pipe 61 can also be linear or the snakelike of extension of wriggling.It is appreciated that with electric-controlled box
The heat of the increase of refrigerant pipeline length inside 50, the automatically controlled component that refrigerant is taken away is also more, and cooling effect is better, can
The length and trend of pipeline to be arranged according to the actual situation.
In some embodiments of the invention, as shown in figures 11-13, refrigerant radiating module 60 further includes radiating fin
62, radiating fin 62 is set on heat-dissipating pipe 61.That is, refrigerant radiating module 60 can be by heat-dissipating pipe 61 and radiating fin
62 compositions increase heat output so as to increase the heat transfer area of heat-dissipating pipe 61.For example, heat-dissipating pipe 61 is " u "-shaped, heat-dissipating pipe
61 respectively penetrate and are pierced by radiating fin 62, and radiating fin 62 can be multiple, axis of multiple radiating fins 62 along heat-dissipating pipe 61
To arrangement.
In some embodiments of the invention, as shown in Figure 14 and Figure 15, refrigerant radiating module 60 further includes that can turn
Dynamic radiator fan 63, to enhance heat dissipation effect.For example, radiator fan 63 may be mounted in the inner bottom wall of cavity, work as heat dissipation
When fan 63 rotates, the air in electric-controlled box 50 can be driven flow, reinforcement heat-dissipating pipe 61, sealing gas and automatically controlled component it
Between heat exchange, quickly reduce the temperature of automatically controlled component, improve the heat dissipation effect of automatically controlled component.Certainly, when refrigerant dissipates
When thermal modules 60 are located at outside cavity, radiator fan 63 be may be mounted at outside cavity.
In some embodiments of the invention, insulating heat-conductive part can be filled in cavity.For example, can be taken out in cavity
Insulating heat-conductive part is filled after vacuum, that is to say, that the air in the electric-controlled box 50 of sealing can be extracted out, refill insulating heat-conductive
The good material of performance.In this way, after heat-dissipating pipe 61 penetrates sealing electric-controlled box 50, it can be with the insulating heat-conductive filled in electric-controlled box 50
Material simultaneously cools down to it, and then cooling automatically controlled component.
In some embodiments of the invention, restricting element 30 can be also provided in cavity, so as to reduce throttling
The condensed water generated at element 30.
According to some embodiments of the present invention, refrigerant radiating module 60 can also include entering refrigerant radiating mould for detecting
The temperature sensor of the refrigerant temperature of block 60, for example, temperature sensor can be located on the tube wall of heat-dissipating pipe 61, temperature sensor
It is electrically connected respectively with automatically controlled component with restricting element 30.In this way, the thermophilic refrigerant after being throttled by restricting element 30 can drop
The temperature of low automatically controlled component makes the temperature of automatically controlled component be no more than it and uses temperature；The temperature detected according to temperature sensor
Degree, by adjusting the flow of restricting element 30, the temperature that temperature sensor can be made to detect is within pre-set interval, that is, passes through
The restricting element 30 of regulating flow quantity makes by the temperature of the refrigerant of refrigerant radiating module 60 within pre-set interval, so that it is guaranteed that
The heat dissipation effect of automatically controlled component, it is ensured that automatically controlled component proper heat reduction, reliability are ensured under hot environment.
