[0035] The embodiments of the utility model provide a heat dissipation system and a heat pump unit, which can help improve the heat dissipation efficiency of electronic devices in the heat pump unit and prevent the overheating of the electronic devices from causing attenuation of the overall energy efficiency of the heat pump unit.
[0036] like Figures 1 to 4As shown, an embodiment of the utility model provides a heat dissipation system, which is used for heat dissipation of electronic devices in a heat pump unit. The heat dissipation system includes: an evaporation component 100, a condensation component 200, a first pipe 300 and a second pipe 400. The evaporation component 100 is connected to the electronic device, and the evaporation component 100 includes a steam outlet 110 and a condensed liquid inlet 120. In an embodiment of the utility model, the evaporation component 100 includes a fluorine cold plate. The condensation component 200 is separated from the electronic device, and the condensation component 200 includes a steam inlet 210 and a condensed liquid outlet 220. In an embodiment of the utility model, the condensation component 200 includes a condensation component 200 including a fin heat exchanger. A circulation loop is formed between the evaporation component 100, the first pipe 300, the condensation component 200, and the second pipe 400, and the first pipe 300 connects the steam outlet 110 with the steam inlet 210, and the steam can flow in the first pipe 300. The second pipe 400 connects the condensed liquid outlet 220 with the condensed liquid inlet 120, and the condensed liquid can flow in the second pipe 400. The plane where the bottom of the condensing component 200 is located is higher than the plane where the top of the evaporating component 100 is located, and a density difference is formed between the medium in the first pipe 300 and the medium in the second pipe 400.
[0037] The technical solution of the utility model dissipates heat from electrical devices by adopting a separate heat pipe. The condensing component 200 is separated from the evaporating component 100, and the evaporating component 100 and the condensing component 200 are connected through the first pipe 300 and the second pipe 400 to form a circulation loop. During operation, a certain amount of working fluid is added to the heat pipe, and these working fluids are collected at the evaporating component 100. After the evaporating component 100 is heated, the working fluid evaporates, and the internal steam pressure increases. The generated steam reaches the condensing component 200 through the first pipe 300, releases latent heat and condenses into liquid. Under the action of gravity, the condensed liquid returns to the evaporating component 100 through the second pipe 400, and the cycle is repeated to dissipate heat. Since the plane where the bottom of the condensing component 200 is located is higher than the plane where the top of the evaporating component 100 is located, a density difference can be formed between the medium in the first pipe 300 and the medium in the second pipe 400. The pressure head provided by this density difference is closely related to the height difference between the condensing component 200 and the evaporating component 100, and is used to balance the pressure loss of steam flow and liquid flow, maintain the normal operation of the heat dissipation system, and can be beneficial to improving the heat dissipation efficiency of electronic devices in the heat pump unit, and avoiding the attenuation effect of overheating of electronic devices on the overall energy efficiency of the heat pump unit.
[0038] In the embodiment of the utility model, the first pipe 300 and the second pipe 400 are copper pipes with a pipe diameter of 9.52 mm and a wall thickness of 0.7 mm.
[0039] like Figures 3 to 5As shown, the evaporation assembly 100 includes: a first heat exchange member 130 and an evaporation pipe 140 passing through the first heat exchange member 130. The evaporation pipe 140 includes a first passage 141 and a second passage 142, and the first passage 141 and the second passage 142 pass through the first heat exchange member 130 at least once.
[0040] like Figure 3 As shown, the evaporation component 100 can be in the form of a double U fluorine cold plate. There are two fluorine cold plates, which are separated and arranged in sequence from top to bottom. The first pipe 300 connects the steam outlet 110 of each fluorine cold plate, and the second pipe 400 connects the condensed liquid inlet 120 of each fluorine cold plate. This application does not limit the number of evaporation components 100, and those skilled in the art can determine the number of evaporation components 100 according to actual needs to achieve better heat dissipation effect.
[0041] like Figure 3 to Figure 4 As shown, the first passage 141 is extended in a serpentine shape, and the first passage 141 includes a first heat exchange tube 1411, a second heat exchange tube 1412, and a third heat exchange tube 1413 which are connected in sequence in a serpentine shape. The first heat exchange tube 1411, the second heat exchange tube 1412, and the third heat exchange tube 1413 are respectively inserted into the first heat exchange element 130.
[0042] like Figure 3 to Figure 4 As shown, the second passage 142 includes a first main path 1421, a second main path 1422, a first branch 1423, and a second branch 1424. The first main path 1421 connects one end of the first branch 1423 and one end of the second branch 1424 to the steam outlet 110, and the second main path 1422 connects the other end of the first branch 1423 and the other end of the second branch 1424 to the condensed liquid inlet 120.
[0043] like Figure 3 to Figure 4 As shown, the first branch 1423 and the second branch 1424 are connected to form a ring passage.
[0044] like Figure 3 to Figure 4 As shown, the first branch 1423 includes a fourth heat exchange tube 1423a passing through the first heat exchange element 130, the second branch 1424 includes a fifth heat exchange tube 1424a passing through the first heat exchange element 130, and the first heat exchange tube 1411, the fourth heat exchange tube 1423a, the second heat exchange tube 1412, the fifth heat exchange tube 1424a, and the third heat exchange tube 1413 are arranged in sequence.
[0045] like Figure 5 As shown, the evaporation assembly 100 may be in the form of a single U-shaped fluorine cold plate, and the evaporation pipe 140 is arranged in a U shape and passes through the first heat exchange element 130 .
[0046] like Figure 2As shown, the condensing assembly 200 includes a fin heat exchanger, and the fin heat exchanger includes a plurality of fin tubes 230, at least one of the plurality of fin tubes 230 is connected to the steam inlet 210, and at least one of the plurality of fin tubes 230 is connected to the condensed liquid outlet 220. At least one fin tube 230 is fixedly connected to the chassis of the fin heat exchanger by a clamp. In the embodiment of the utility model, the heat exchange area of the fin of the fin heat exchanger is larger than the heat exchange area required by the heat dissipation system, and the wall temperature of the separated heat pipe has a fast self-regulating characteristic according to the heat source heating power, and the heat will be quickly taken away. At the same time, the heat pipe has a very high thermal conductivity, and due to phase change heat transfer, it also has excellent thermal conductivity.
[0047] In the embodiment of the present utility model, Figure 6 As shown, one end of one of the plurality of fin tubes 230 near the bottom of the fin heat exchanger is used to connect to the steam inlet 210 , and one end of another fin tube 230 is used to connect to or condense the liquid outlet 220 .
[0048] In another embodiment, one end of the plurality of fin tubes 230 is used to connect to the steam inlet 210 or the condensed liquid outlet 220, and the other ends of the plurality of fin tubes 230 are connected to each other through the interconnector 240. The number of fin tubes 230 connected to the steam inlet 210 is greater than or equal to the number of fin tubes 230 connected to the condensed liquid outlet 220. For example, in one embodiment, one end of two fin tubes 230 of the plurality of fin tubes 230 near the bottom of the fin heat exchanger is used to connect to the steam inlet 210, and one end of one fin tube 230 is used to connect to the condensed liquid outlet 220, such as Figure 7 As shown, the other ends of the three fin tubes 230 are connected to each other through a claw-type tee.
[0049] Alternatively, one end of two of the multiple fin tubes 230 of the fin heat exchanger is selected to be connected to the steam inlet 210, one end of the two fin tubes 230 is selected to be connected to the condensed liquid outlet 220, and the other ends of the four fin tubes 230 are interconnected through interconnecting parts.
[0050] Alternatively, one end of three of the multiple fin tubes 230 may be selected to be connected to the steam inlet 210, one end of two of the fin tubes 230 may be selected to be connected to the condensed liquid outlet 220, and the other ends of the five fin tubes 230 may be connected to each other through interconnectors. The present application does not limit the manner in which the fin tubes 230 at the condensation assembly 200 are connected to the steam inlet 210 or the condensed liquid outlet 220, and those skilled in the art can determine the manner in which the fin tubes 230 are connected according to actual heat dissipation needs.
[0051] In the embodiment of the utility model, the estimated heating power of the single-sided heat source is 921.15W to 1074.68W. The temperature of the fin heat exchanger is equal to the operating temperature, which is about -35-24°C. The evaporation component 100 is installed in the electric control box, the temperature of the electric control box is about 50-100°C, and the working fluid temperature is about 40°C. The refrigerant uses R410A refrigerant, the logarithmic mean temperature difference of the severe working condition is 67.2°C, and the ambient temperature is 2 / 1°C. The heavy pipes of the heat dissipation system are made of copper pipe materials with good temperature uniformity. The heat transfer coefficient on the phase change side of the heat pipe is ∞, and the heat transfer capacity of the wind side is checked. In the case of natural convection, the heat transfer coefficient is 20.83. In the case of forced convection, the flow rate of the fluid through the front of the fin heat exchanger under standard conditions is limited to 2 to 3m / s. Too high wind speed will cause excessive pressure drop and increase power consumption. Too low wind speed will cause the heat transfer coefficient of the outer film of the tube to decrease, and the heat transfer capacity of the heat pipe will not be fully exerted. In an embodiment where one end of two fin tubes 230 is used to connect to the steam inlet 210 and one fin tube 230 is used to connect to the condensed liquid outlet 220, it is beneficial to achieve the heat exchange and heat dissipation requirement of 921.15W.

The heat dissipation system includes: an evaporation component 100, a condensation component 200, a first pipe 300 and a second pipe 400. The evaporation component 100 is connected to the electronic device, and the evaporation component 100 includes a steam outlet 110 and a condensed liquid inlet 120. The condensation component 200 is separated from the electronic device, and the condensation component 200 includes a steam inlet 210 and a condensed liquid outlet 220. A circulation loop is formed between the evaporation component 100, the first pipe 300, the condensation component 200, and the second pipe 400. The first pipe 300 connects the steam outlet 110 with the steam inlet 210, and the steam can flow in the first pipe 300. The second pipe 400 connects the condensed liquid outlet 220 with the condensed liquid inlet 120, and the condensed liquid can flow in the second pipe 400. The plane where the bottom of the condensation component 200 is located is higher than the plane where the top of the evaporation component 100 is located, and a density difference is formed between the medium in the first pipe 300 and the medium in the second pipe 400.
[0054] The technical solution of the utility model performs main heat dissipation of the heat pump unit through the main heat exchange system, performs auxiliary heat dissipation of the electrical components through the heat dissipation system, and performs heat dissipation in the form of a separate heat pipe in the heat dissipation system. The condensation component 200 is separated from the evaporation component 100, and the evaporation component 100 and the condensation component 200 are connected through the first pipe 300 and the second pipe 400 to form a circulation loop. After the evaporation component 100 is heated, the internal steam pressure increases, and the generated steam reaches the condensation component 200 through the first pipe 300, releases latent heat and condenses into liquid. Under the action of gravity, the condensed liquid returns to the evaporation component 100 through the second pipe 400, and the cycle is repeated to dissipate heat. Since the plane where the bottom of the condensing component 200 is located is higher than the plane where the top of the evaporating component 100 is located, a density difference can be formed between the medium in the first pipe 300 and the medium in the second pipe 400, so as to balance the pressure loss of steam flow and liquid flow, maintain the normal operation of the heat dissipation system, and be beneficial to improving the heat dissipation efficiency of electronic components in the heat pump unit, avoiding the attenuation effect of overheating of electronic components on the overall energy efficiency of the heat pump unit, and improving the heat dissipation efficiency of the heat pump unit.

The technical solution of the utility model connects the plurality of fin tubes 230 of the condensing component to the main heat exchange system for heat exchange, and by connecting at least one fin tube 230 to the steam inlet, and at least one fin tube 230 to the condensed liquid outlet, the heat dissipation system and the main heat exchange system can both exchange heat through the fin tubes 230 of the condensing component, and the heat dissipation system and the main heat exchange system exchange heat through different fin tubes 230, which is beneficial to improving the heat exchange efficiency, saving energy, and making the internal structure of the heat pump unit more compact.
