The air conditioning system 1 according to the embodiment of the first aspect of the present utility model will be described below with reference to the accompanying drawings.

As shown in Figures 1-14, the air conditioning system 1 according to the embodiment of the present invention includes: a compressor 10, an outdoor heat exchanger 20, a throttling element 30, an indoor heat exchanger 40, an electric control box 50 and a refrigerant heat dissipation module 60 .

Specifically, the compressor 10, the outdoor heat exchanger 20, the throttling element 30, and the indoor heat exchanger 40 are connected in sequence through refrigerant pipes to form a closed circuit. The electric control box 50 includes a sealed cavity and electric control components arranged in the cavity, and the electric control components are electrically connected with the compressor 10 . The refrigerant heat dissipation module 60 is used for cooling electronic control components, and the refrigerant heat dissipation module 60 is connected in series between the compressor 10 and the indoor heat exchanger 40 .

Thus, the outlet refrigerant of the indoor heat exchanger 40 is used to dissipate heat from the electronic control components, so that the cooling effect is good; moreover, the electronic control components are arranged in a closed space, so that due to the limited air in the closed space, not only The cooling effect is better, and there will not be more condensed water near the electronic control components, which ensures the reliability of the electronic control components.

It can be understood that, as shown in FIG. 1, the air conditioning system 1 can be applied to a single cooler; further, as shown in FIG. 2, the air conditioning system 1 can also be applied to a heating and cooling machine. For example, the air conditioning system 1 also includes: The switchable reversing device 70 between the first state and the second state, the reversing device 70 has a first interface 71, a second interface 72, a third interface 73 and a fourth interface 74, for example, the reversing device 70 is four The one-way valve and the four-way valve are electrically connected with the electric control components. The first interface 71 and the third interface 73 communicate with the compressor 10 respectively. For example, the compressor 10 has a discharge port and a suction port, and the suction port is formed on the liquid reservoir 11 of the compressor 10. The first port 71 is connected to the compressor 10. The exhaust port is connected, and the third interface 73 is connected with the suction port. The outdoor heat exchanger 20 communicates with the second interface 72 , and the indoor heat exchanger 40 communicates with the fourth interface 74 . Here, the refrigerant cooling module 60 is connected in series between the accumulator 11 of the compressor 10 and the third interface 73 .

In this way, the refrigerant discharged from the compressor 10 enters the four-way valve, and the four-way valve In the cooling working condition, the refrigerant enters the outdoor heat exchanger 20 for condensation after passing through the four-way valve, and the temperature of the refrigerant decreases. Next, the cooled refrigerant enters the throttling element 30 , and enters the indoor heat exchanger 40 after being throttled and cooled by the throttling element 30 . The low-temperature refrigerant enters the indoor heat exchanger 40 to evaporate and absorb heat, and the indoor heat exchanger 40 completes the cooling of the indoor air and completes the refrigeration function. The refrigerant coming out of the indoor heat exchanger 40 passes through the four-way valve, and then enters the refrigerant heat dissipation module 60. In the refrigerant heat dissipation module 60, the refrigerant with a lower temperature takes away the calorific value of the electronic control components to complete the cooling of the electronic control components. , and finally the refrigerant returns to the compressor 10 through the accumulator 11, the compression process is completed in the compressor 10, and the compressed refrigerant is discharged from the exhaust port of the compressor 10, thus completing a cycle of the refrigeration process.

When the reversing device 70 is in the second state, the first port 71 communicates with the fourth port 74 and the second port 72 communicates with the third port 73 . In this way, the refrigerant discharged from the compressor 10 enters the four-way valve, and the four-way valve is in the heating mode. After passing through the four-way valve, the refrigerant enters the indoor heat exchanger 40 and condenses in the indoor heat exchanger 40 to complete the heating of the indoor air. . The temperature of the refrigerant passing through the indoor heat exchanger 40 decreases, and the cooled refrigerant enters the throttling element 30 , and enters the outdoor heat exchanger 20 after throttling and cooling by the throttling element 30 . The refrigerant evaporates and absorbs heat in the outdoor heat exchanger 20, the refrigerant coming out of the outdoor heat exchanger 20 passes through the four-way valve, and then enters the refrigerant heat dissipation module 60, and the refrigerant with a lower temperature in the refrigerant heat dissipation module 60 takes away the electric control unit The heat generated in the device completes the cooling of the electronic control components, and finally returns to the compressor 10 through the liquid reservoir 11, and the compression process is completed in the compressor 10, and the compressed refrigerant is discharged from the exhaust port of the compressor 10. So far, one cycle of the heating process is completed.

According to some embodiments of the present invention, as shown in FIG. 3 , the refrigerant cooling module 60 includes a heat dissipation pipe 61 connected to the refrigerant pipe, and the refrigerant can flow into the heat dissipation pipe 61 from the refrigerant pipe. For example, the heat dissipation pipe 61 may be a copper pipe, so that the thermal conductivity is better. The cross section of the heat dissipation pipe 61 may be circular or rectangular, which is not specifically limited in the present invention.

Optionally, the heat dissipation pipe 61 and the refrigerant pipe may be connected through a heat conduction member, and the heat conduction member is an aluminum member, a copper member, or a semiconductor refrigeration sheet.

Optionally, the heat dissipation pipe 61 may be formed by a part of the refrigerant pipe, so that the structure is relatively simple, and the assembly is also simplified.

In some embodiments of the present invention, the cooling medium cooling module 60 can be located outside the cavity, so that the cooling pipe 61 cools down the temperature of the electronic control components inside the cavity by cooling the outside of the electric control box 50 .

Further, the cavity can be made of heat-conducting material, and the heat dissipation pipe 61 is bonded to the outer surface of the cavity, so as to enhance the cooling effect on the cavity. For example, the heat dissipation pipe 61 may be in contact with one surface of the electric control box 50 , or may be in contact with multiple surfaces of the electric control box 50 , or the heat dissipation pipe 61 may also surround the outer surface of the electric control box 50 .

It can be understood that, as shown in FIG. 3 and FIG. 12 , at least a part of the cooling medium cooling module 60 is disposed in the cavity, and the cooling tube 61 is connected with the cooling medium tube through a through hole opened in the cavity. For example, the heat dissipation pipe 61 can be partially embedded in the electric control box 50 , or can be completely arranged inside the electric control box 50 . The heat dissipation pipe 61 penetrates into the sealed cavity, contacts with the sealed gas in the cavity, and cools the sealed gas, and the cooled gas then cools the electric control components that generate heat. That is to say, the radiating pipe 61 penetrates into the airtight electric control box 50, and then passes out of the electric control box 50, thereby taking away the heat of the electronic control components and reducing the temperature of the electronic control components. Ensure the reliability of electronic control components and the normal use of air conditioners.

In some specific embodiments of the present utility model, the heat dissipation pipe 61 can be attached to the electronic control components. That is to say, the radiating pipe 61 penetrates the sealed electric control box 50 and directly contacts the electric control components with high heat generation, so that the flowing low-temperature refrigerant directly cools the electric control components, and at the same time, it can also cool the sealed air. In turn, other components are cooled to ensure the reliability of electronic control components at high temperatures.

Optionally, as shown in Figure 12, a heat dissipation plate 51 can be provided on the electronic control components, and the heat dissipation pipe 61 can be attached to the heat dissipation plate 51. For example, the heat dissipation plate 51 can be an aluminum substrate, thereby increasing the heat dissipation area and enhancing heat radiation.

Of course, the heat dissipation pipe 61 may be in contact with the inner wall of the cavity. For example, the electric control box 50 has two layers, the outer layer is made of heat-insulating material, and the inner layer is made of heat-conducting material. Thereby, the inner layer and the sealed air are cooled, and the cooled inner layer and air then cool the heating electric control components. Here, a part of the heat dissipation pipe 61 can be embedded in the inner layer, and a part is in contact with the air in the electric control box 50; or, the heat dissipation pipe 61 can also be arranged inside the inner layer, and completely contact the inner layer, for example, as shown in Figure 3 and Figure 6 As shown, the cavity includes a lower box body 52 and an upper cover 53 , the upper cover 53 covers the lower box body 52 , and the heat dissipation pipe 61 is embedded in the upper cover 53 .

Wherein, the orientation of the heat dissipation pipe 61 may pass through one surface or multiple surfaces of the inner layer. It can be understood that when the heat dissipation pipe 61 passes through one surface of the inner layer, it should be the surface close to the electric control component that generates a large amount of heat.

Optionally, as shown in FIG. 9, the heat dissipation pipe 61 is configured in a "U" shape. For example, the heat dissipation pipe 61 penetrates the airtight electric control box 50, and directly contacts with the electric control components with large heat generation. The low-temperature refrigerant absorbs the heat of the electronic control components to reduce the temperature of the electronic control components, passes through a U-shaped path, and then passes through the electric control box 50 . The heat dissipation pipe 61 inside the electric control box 50 may have various orientations. For example, the heat dissipation pipe 61 may also be in a straight line or a meandering serpentine shape. It can be understood that as the length of the refrigerant pipeline inside the electric control box 50 increases, the heat of the electronic control components will be taken away by the refrigerant, and the cooling effect will be better. The length and direction of the pipeline can be set according to the actual situation.

In some embodiments of the present invention, as shown in FIGS. 7-9 , the refrigerant heat dissipation module 60 further includes heat dissipation fins 62 , and the heat dissipation fins 62 are sheathed on the heat dissipation pipes 61 . That is to say, the refrigerant heat dissipation module 60 may be composed of heat dissipation pipes 61 and heat dissipation fins 62 , thereby increasing the heat transfer area of the heat dissipation pipes 61 and increasing the heat transfer amount. For example, the heat dissipation pipe 61 is U-shaped, and the heat dissipation pipe 61 penetrates into and passes through the heat dissipation fins 62 respectively.

In some specific embodiments of the present invention, as shown in FIG. 10 and FIG. 11 , the refrigerant cooling module 60 further includes a rotatable cooling fan 63 to enhance the cooling effect. For example, the heat dissipation fan 63 can be installed on the inner bottom wall of the cavity. When the heat dissipation fan 63 rotates, it can drive the air flow in the electric control box 50 to strengthen the heat dissipation between the heat dissipation pipe 61, the sealing gas and the electric control components. Exchange, reduce the temperature of electronic control components faster, and improve the heat dissipation effect of electronic control components. Certainly, when the cooling medium cooling module 60 is arranged outside the cavity, the cooling fan 63 can be installed outside the cavity.

In some specific embodiments of the present invention, the cavity may be filled with insulating and heat-conducting components. For example, the cavity can be filled with insulating and heat-conducting elements after being vacuumed. That is to say, the air in the sealed electric control box 50 can be extracted, and then filled with a material with good insulation and thermal conductivity. In this way, when the radiating pipe 61 penetrates into the sealed electric control box 50, it can contact the insulating and heat-conducting material filled in the electric control box 50 and cool it down, thereby cooling the electric control components.

According to some embodiments of the present utility model, the refrigerant heat dissipation module 60 may also include a temperature sensor for detecting the temperature of the refrigerant entering the refrigerant heat dissipation module 60, for example, the temperature sensor may be arranged on the pipe wall of the heat dissipation pipe 61, the temperature sensor and the joint The flow elements 30 are respectively electrically connected to the electric control components. In this way, the temperature-appropriate refrigerant flowing out from the indoor heat exchanger 40 can reduce the temperature of the electronic control components, so that the temperature of the electronic control components does not exceed its operating temperature; , the temperature detected by the temperature sensor can be kept within the preset range, that is, the temperature of the refrigerant passing through the refrigerant cooling module 60 can be kept within the preset range through the throttling element 30 that can adjust the flow rate, so as to ensure the stability of the electronic control components. The heat dissipation effect ensures the normal heat dissipation of electronic control components in a high temperature environment, and the reliability is guaranteed.
