In the embodiments of the present utility model, the ice melting structure of the condenser includes a condenser 110, a valve assembly 120, a first heat pipe 130, and a chassis 140.

[0037] The valve assembly 120 includes a check valve 122, and the check valve 122 is in communication with the condenser 110. One end of the first heat pipe 130 is in communication with the condenser 110, and the other end is in communication with the condenser 110 through the check valve 122. At least part of the refrigerant medium can circulate between the first heat pipe 130 and the condenser 110. The chassis 140 is disposed on the side of the condenser 110 close to the ground, and the first heat pipe 130 is disposed between the condenser 110 and the chassis 140 and passes through the edge portion of the chassis 140.

[0038] In the embodiment of the present utility model, by disposing the first heat pipe 130 between the condenser 110 and the chassis 140 and passing through the edge portion of the chassis 140, when a part of the high-temperature refrigerant medium in the condenser 110 flows in the first heat pipe 130, it can heat the edge portion of the chassis 140 and the connection between the chassis 140 and the condenser 110 to eliminate the icing on the edge portion of the chassis 140 and avoid the continuous accumulation of icing at this place, thereby affecting the heat exchange function and heat exchange efficiency of the condenser 110.

[0039] By disposing the first heat pipe 130 at the edge portion of the chassis 140, the chassis 140 does not need to be additionally provided with a heating belt or a heater for deicing, reducing the production cost, and at the same time, it can efficiently eliminate the icing that is difficult to melt at the edge portion of the chassis 140.

[0040] The deicing structure of the condenser in the embodiment of the present utility model disposes the first heat pipe 130 between the condenser 110 and the chassis 140 and passes through the edge portion of the chassis 140, so that a part of the high-temperature refrigerant medium in the condenser 110 can flow through the first heat pipe 130 to heat the edge portion of the chassis 140 to eliminate the icing on the edge portion of the chassis 140, prevent the accumulation of icing at the corner of the chassis 140, improve the reliability of the condenser 110, and at the same time, by disposing a check valve 122 between the first heat pipe 130 and the condenser 110, it can prevent the refrigerant medium in the first heat pipe 130 from flowing back or leaking, avoiding waste of heat energy.

[0041] In some embodiments, the chassis 140 includes at least one hollow portion 141, and the hollow portion 141 is disposed opposite to the condenser 110. The condensed water generated by the condenser 110 can flow out of the chassis 140 through the hollow portion 141.

[0042] As Figure 4 shown, in this embodiment, the hollow portion 141 is disposed at the edge portion of the chassis 140 and is disposed opposite to the bottom of the condenser 110. The condensed water generated during the operation of the condenser 110 can flow to the outside through the hollow portion 141 of the chassis 140 to avoid the condensed water from condensing into ice on the chassis 140.

[0043] In some embodiments, the first heat pipe 130 includes an ice melting portion 131 disposed between the hollow portion 141 and the condenser 110.

[0044] In this embodiment, the ice melting portion 131 is located between the bottom of the hollow portion 141 and the condenser 110, enabling the first heat pipe 130 to heat and melt the ice formed between the bottom of the hollow portion 141 and the condenser 110, preventing the continuous accumulation of ice at the edge of the chassis 140 and ensuring that the condensed water can flow out of the chassis 140 smoothly.

[0045] In some embodiments, the chassis 140 further includes a water receiving portion 142 disposed on the side of the chassis 140 close to the ground, and the surface of the water receiving portion 142 is disposed opposite to the hollow portion 141. The water receiving portion 142 can receive the condensed water flowing out of the hollow portion 141.

[0046] In this embodiment, the condensed water generated during the operation of the condenser 110 can be received by the water receiving portion 142 after flowing to the hollow portions 141 at different positions of the chassis 140, and the water receiving portion 142 can discharge the received condensed water centrally.

[0047] As Figure 4 、 Figure 5 shown, the condensed water on the chassis 140 can flow to the water receiving portion 142 through the hollow portions 141 at positions B, C, and D in Figure 4 . The ice melting portion 131 of the first heat pipe 130 is also located at positions B, C, and D in Figure 4 . The ice melting portion 131 can heat the water receiving portion 142 to prevent the condensed water from freezing at the water receiving portion 142 and causing poor drainage.

[0048] Furthermore, the ice melting structure of the condenser further includes a drainage member 143 disposed on the side of the water receiving portion 142 close to the ground. The drainage member 143 is communicated with the water receiving portion 142 and can discharge the condensed water located in the water receiving portion 142.

[0049] In this embodiment, the surface of the water receiving portion 142 is inclined. The height of the surface of the water receiving portion 142 at positions B and D relative to the ground is higher than that of the surface of the water receiving portion 142 at position C, that is, the surface of the water receiving portion 142 at position C is at the lowest position. The drainage member 143 is disposed at the lowest position of the water receiving portion 142. After the water receiving portion 142 centrally collects the condensed water at the hollow portions 141 at different positions, the condensed water can be concentrated at position C and discharged outward through the drainage member 143.

[0050] In some embodiments, the valve assembly 120 includes a liquid distribution pipe 121. The check valve 122 is in one-way communication with the liquid distribution pipe 121. The liquid distribution pipe 121 is in communication with the condenser 110. The refrigerant inlet of the first heat pipe 130 is in communication with the condenser 110. The refrigerant outlet of the first heat pipe 130 is in communication with the check valve 122. The refrigerant medium in the first heat pipe 130 flows into the liquid distribution pipe 121 after passing through the check valve 122.

[0051] As Figure 1 shown, in this embodiment, the refrigerant outlet of the first heat pipe 130 is in communication with the check valve 122. The connecting pipe 170 connects the check valve 122 and the liquid distribution pipe 121. The high-temperature refrigerant medium in the condenser 110 flows into the first heat pipe 130 through the refrigerant inlet of the first heat pipe 130, heats the edge portion of the chassis 140 along the extending path of the first heat pipe 130, and finally flows from the refrigerant outlet of the first heat pipe 130 to the check valve 122 and finally returns to the condenser 110 through the liquid distribution pipe 121 to form a circulating flow. Since the check valve 122 is in one-way communication with the liquid distribution pipe 121, the refrigerant medium flowing out of the check valve 122 or the refrigerant medium in the liquid distribution pipe 121 cannot flow back into the first heat pipe 130, ensuring the normal circulating flow of the refrigerant medium and preventing the waste of the heat energy in the refrigerant medium.

[0052] In some embodiments, the ice melting structure of the condenser further includes a three-way valve 150. The first end and the second end of the three-way valve 150 are in communication with the condenser 110. The third end of the three-way valve 150 is in communication with the refrigerant inlet of the first heat pipe 130.

[0053] In this embodiment, the condenser 110 includes a plurality of second heat pipes. Each second heat pipe has a flow channel for the refrigerant medium to flow. The first end of the three-way valve 150 is in communication with one of the second heat pipes. The second end is in communication with another second heat pipe in the condenser 110. A part of the high-temperature refrigerant medium in the condenser 110 flows from the first end of the three-way valve 150 to the second end, and a part of the high-temperature refrigerant medium flows from the first end of the three-way valve 150 to the third end and then flows into the first heat pipe 130, so that the high-temperature refrigerant medium in the first heat pipe 130 can heat the edge portion of the chassis 140 and can flow back after heating to form a recycling.

[0054] In some embodiments, the ice melting structure of the condenser further includes a refrigerant pipeline 160. The refrigerant pipeline 160 connects the external refrigerant medium and the condenser 110.

[0055] In this embodiment, the refrigerant pipeline 160 can direct the high-temperature and high-pressure refrigerant medium in the outside world into the condenser 110, so that the condenser 110 can perform heat exchange work. A part of the high-temperature refrigerant medium inside the condenser 110 can flow into the first heat pipe 130 to perform ice melting work.

[0056] In some embodiments, the condenser 110 includes a fin assembly and a heat pipe assembly. The heat pipe assembly is disposed through the fin assembly. One end of the heat pipe assembly communicates with the refrigerant pipe 160, and the other end communicates with the three-way valve 150.

[0057] In this embodiment, the heat pipe assembly includes a plurality of second heat pipes. The first heat pipe 130 communicates with the second heat pipes, so that a part of the high-temperature refrigerant medium inside the condenser 110 can flow into the first heat pipe 130 to melt the ice formed on the edge portion of the chassis. The fin assembly includes a plurality of heat exchange fins arranged at intervals. Each second heat pipe of the heat pipe assembly is disposed through the plurality of heat exchange fins, so that when the high-temperature refrigerant medium flows into the condenser 110, efficient heat exchange can be performed.

[0058] The present utility model further provides a heat pump device. The heat pump device includes a heat pump assembly and the ice melting structure of the condenser according to any one of the foregoing embodiments of the present utility model. The heat pump assembly communicates with the ice melting structure of the condenser. The refrigerant medium located in the heat pump assembly can circulate between the heat pump assembly, the condenser 110, the valve assembly 120, and the first heat pipe 130.

[0059] The ice melting structure of the condenser includes the condenser 110, the valve assembly 120, the first heat pipe 130, and the chassis 140. One end of the first heat pipe 130 communicates with the condenser 110, and the other end communicates with the valve assembly 120. The refrigerant medium in the condenser 110 can flow into the first heat pipe 130. The chassis 140 is disposed on the side of the condenser 110 close to the ground. The first heat pipe 130 is disposed between the condenser 110 and the chassis 140 and passes through the edge portion of the chassis 140.

[0060] The heat pump assembly includes a compressor, an evaporator, and a throttle. The evaporator is used to absorb external heat. The throttle is used to control the flow rate of the refrigerant medium flowing into the evaporator. The compressor is used to compress the received low-temperature and low-pressure refrigerant medium into a high-temperature and high-pressure refrigerant medium, and direct the high-temperature and high-pressure refrigerant medium to the condenser 110, so that the condenser 110 can perform heat exchange. The heat-exchanged refrigerant medium flows through the throttle and the evaporator and then returns to the compressor again to complete one cycle. The compressor compresses the received low-temperature and low-pressure refrigerant medium and starts the next cycle of heating. When the high-temperature and high-pressure refrigerant medium flows into the condenser 110, a part of the high-temperature and high-pressure refrigerant medium can flow into the first heat pipe 130, so that the first heat pipe 130 can heat and melt the ice formed on the edge portion of the chassis 140.

[0061] The condensed water generated during the operation of the compressor and the condenser 110 can be received and discharged by the chassis 140 located below. The ice formed at the edge of the chassis 140 can be heated and melted by the first heat pipe 130, and the chassis 140 can discharge the condensed water generated after melting to ensure the normal operation of the heat pump device and prevent the heat exchange efficiency and stability of the heat pump device from being seriously affected by icing.

[0062] By arranging the first heat pipe 130 at the edge of the chassis 140, the chassis 140 does not need to be additionally provided with a heating tape or a heater for ice melting, which reduces the production cost and can efficiently eliminate the ice that is difficult to melt at the edge of the chassis 140.

[0063] The heat pump device according to the embodiment of the present invention includes an ice melting structure for the condenser. The ice melting structure of the condenser enables a part of the high-temperature refrigerant medium in the condenser 110 to flow through the first heat pipe 130 and heat the edge part of the chassis 140 by arranging the first heat pipe 130 between the condenser 110 and the chassis 140 and passing through the edge part of the chassis 140, so as to eliminate the ice at the edge part of the chassis 140 and prevent the accumulation of ice at the corners of the chassis 140, improving the reliability of the heat pump device. At the same time, by arranging a one-way valve 122 between the first heat pipe 130 and the condenser 110, the refrigerant medium located in the first heat pipe 130 can be prevented from flowing back or leaking, and the waste of heat energy of the heat pump device can be prevented.

[0064] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
