Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of electronic components, in particular to an air-cooled heat dissipation device and a heat pump system. Background Art

[0002] One of the reasons that affect the performance of many electrical devices is the heating of electronic components. Once the temperature of key electronic components rises, the performance of the entire electrical device will decline. The more conventional means in the prior art is to set a heat sink on the electronic components to accelerate the heat dissipation through the heat sink, and then use a fan to accelerate the air flow of the heat sink to achieve the purpose of strengthening the heat dissipation.

[0003] However, on the one hand, the heat generated by electronic components makes the surrounding air temperature relatively high. The air flowing through the heat sink under the action of the fan has a relatively high temperature, and its cooling effect on the heat sink is limited. On the other hand, the fan makes the air flow direction around the heat sink relatively single, and the heat dissipation performance of some areas of the heat sink cannot be effectively utilized, resulting in the inability to further improve the heat dissipation capacity of the entire electronic components.

DETAILED DESCRIPTION

[0074] In combination with the accompanying drawings and the description of the specific embodiments of the present invention, the details of the present invention can be more clearly understood.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0076] In order to solve the problem that the heat dissipation capacity of the heating unit cannot be further improved, an air-cooled heat dissipation device is proposed in this application. Figure 1 This is a schematic diagram of the structure of the air-cooled heat dissipation device in the embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of the air-cooled heat dissipation device in another embodiment of the utility model. Figure 3 for Figure 1 The enlarged schematic diagram at I in the figure is as follows: Figures 1 to 3 As shown, the air-cooled heat dissipation device may include: a shell 1; a heating unit 2; a heat sink 3 for dissipating heat to the heating unit 2; a fan 4 and a guide unit 5 arranged in the shell 1, the guide unit 5 forming a first flow channel 51 and a second flow channel 52; the fan 4 can introduce air outside the shell 1 into the interior of the shell 1, and under the action of the guide unit 5, the air flows through the first flow channel 51 and the second flow channel 52 respectively and flows through the heat sink 3 from two different directions.

[0077] In the present application, the heat sink 3 is first used to dissipate heat from the heating unit 2, thereby reducing the temperature of the heating unit 2. Secondly, the fan 4 in the air-cooled heat sink is used to introduce air from outside the housing 1 into the housing 1. In this way, the temperature of the air introduced from outside the housing 1 will be much lower than the temperature of the air originally inside the housing 1. Under the action of the air guide unit 5, the air flows through the first flow channel 51 and the second flow channel 52 respectively and flows through the heat sink 3 from two different directions. In this way, the air with a lower temperature introduced from outside the housing 1 can fully exchange heat with different areas of the heat sink 3, avoiding that some areas of the heat sink 3 cannot exchange heat with air with a sufficient flow rate, resulting in its heat dissipation performance not being fully utilized, thereby further improving the heat dissipation effect of the heat sink 3.

[0078] In order to better understand the air-cooling heat dissipation device in this application, it will be further explained and illustrated below. Figures 1 to 3 As shown, the air-cooled heat dissipation device may include: a housing 1, a heating unit 2, a heat sink 3, a fan 4, and a guide unit 5, etc. Among them, the housing 1 is used to accommodate the heating unit 2, the heat sink 3, the fan 4, the guide unit 5 and other components, etc., and plays a certain role in protection and rain protection. The heating unit 2 can be various electronic components, which will emit heat during operation, causing its own temperature to rise. If it cannot be cooled down in time, its own performance will be affected. As a feasible method, the air-cooled heat dissipation device can be a heat pump device, and the heating unit 2 can be a device that generates heat and causes the temperature to rise when the heat pump device is running. For example, it can be a control unit in the heat pump device, a frequency converter that controls the compressor 9, etc. Correspondingly, the air-cooled heat dissipation device can include: a compressor 9; a frequency converter electrically connected to the compressor 9.

[0079] like Figures 1 to 3 As shown, the heat sink 3 is used to dissipate heat from the heating unit 2, thereby reducing the temperature of the heating unit 2. The heat sink 3 can be a heat sink of various structures, and can be in close contact with the heating unit 2 to achieve efficient heat conduction, or can achieve efficient heat conduction with the heating unit 2 through a thermally conductive material, and the thermally conductive material can be a material such as thermally conductive silicone grease, or a heat conductive plate with a high thermal conductivity coefficient, such as a metal plate, disposed between the heating unit 2 and the heat sink 3. The metal plate can also play a role in fixing the heating unit 2 and the heat sink 3 at the same time.

[0080] like Figures 1 to 3As shown, the fan 4 and the guide unit 5 are arranged in the housing 1. The guide unit 5 can form a first flow channel 51 and a second flow channel 52. Under the action of the fan 4, the air outside the housing 1 is introduced into the interior of the housing 1. At the same time, under the action of the guide unit 5, the air flows through the first flow channel 51 and the second flow channel 52 respectively, so that the air flowing in from the outside of the housing 1 flows through the heat sink 3 from two different directions. By allowing the air to blow to the heat sink 3 from different directions, different areas of the heat sink 3 can fully exchange heat with the air, so as to further improve the heat dissipation effect of the heat sink 3. If the air blows to the heat sink 3 from only one direction, the speed of the air will decrease when it flows through the heat sink 3, especially when the air flows through the second half of the heat sink 3, the air flow rate is already very low, and the heat exchange rate between the air and the heat sink 3 will be greatly reduced. At this time, the heat dissipation performance of this part of the heat sink 3 area cannot be fully utilized.

[0081] As feasible, Figure 3 As shown, the heat sink 3 may include a body 31 having a first surface and a second surface opposite to each other; and a plurality of fin portions 32 located on the first surface of the body 31. In one embodiment, the second surface of the body 31 may be in contact with the heating unit 2 for heat conduction. In another embodiment, the second surface of the body 31 and the heating unit 2 are heat-conducted through a heat-conducting material. The plurality of fin portions 32 are arranged at intervals along the first direction, and the plurality of fin portions 32 extend along the second direction.

[0082] The air flowing through the first flow channel 51 may flow through the fin portion 32 from a first direction.

[0083] In order to achieve the above purpose, as feasible, Figure 3 As shown, the fin portion 32 has a hollow structure 322, so that the air flowing through the first flow channel 51 flows through the hollow structure 322 of the fin portion 32 from the first direction. In order to further reduce the resistance of the fin portion 32 to the air and allow the air to flow through more fin portions 32, the hollow structures 322 on the fin portion 32 can be arranged in a straight line along the first direction.

[0084] The air flowing through the second flow channel 52 can flow through the gaps between the fin portions 32 from the second direction, thereby minimizing the resistance of the fin portions 32 to the air and allowing the air to flow through a greater distance of the fin portions 32 at the highest possible speed, thereby improving the heat exchange effect with the fin portions 32 .

[0085] The first direction and the second direction may have an angle, which allows the air flowing through the first flow channel 51 and the second flow channel 52 to flow through the heat sink 3 from two completely different directions, thereby allowing the air to flow through different areas of the heat sink 3 that are relatively far apart. The specific angle of the angle is not limited in the present application.

[0086] In a specific embodiment, the first direction may be perpendicular to the second direction. In a feasible embodiment, Figure 3 As shown, the first direction may be a vertical direction, and the second direction may be a horizontal direction. In another feasible implementation, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0087] In another specific embodiment, the first direction may be opposite to the second direction. The air flowing through the first flow channel 51 flows through the fin portion 32 from the first end of the fin portion 32 along the first direction. The air flowing through the second flow channel 52 flows through the fin portion 32 from the second end of the fin portion 32 along the second direction, and the first end and the second end of the fin portion 32 are arranged opposite to each other. In this way, it can be ensured that both ends of the fin portion 32 can exchange heat with the air flowing at a higher speed, so that different areas of the fin portion 32 can fully exchange heat with the air, so as to further improve the heat dissipation effect of the heat sink 3.

[0088] As feasible, Figure 1 and Figure 2 As shown, the air-cooled heat dissipation device may include: a partition unit 6, which divides the interior of the housing 1 into a first space 7 and a second space 8. The housing 1 of the second space 8 may be provided with an air inlet 11, and the second space 8 forms a third flow channel 81, and the third flow channel 81 connects the air inlet 11 with the first flow channel 51 and the second flow channel 52. The heating unit 2 is arranged in the second space 8, and the fan 4 is arranged in the first space 7. Under the action of the fan 4, the air with a lower temperature outside the housing 1 is introduced into the second space 8 and passes through the third flow channel 81. After that, under the action of the guide unit 5, it flows through the first flow channel 51 and the second flow channel 52 respectively and flows through the heat sink 3 from two different directions. Further, the heating unit 2 may be arranged in the third flow channel 81, so that the air flowing through the third flow channel 81 flows through the surface of the heating unit 2, thereby improving the heat dissipation effect of the heating unit 2.

[0089] In some embodiments, Figure 2 As shown, one of the directions in which the air flows at the heat sink 3 is substantially the same as the extension direction of the heat sink 3, specifically, it flows in the vertical direction. The direction in which the air flows at the heating unit 2 is substantially the same as the extension direction of the heating unit 2, specifically, it flows in the vertical direction. That is to say, under the action of the fan 4, the air introduced from the third flow channel 81 first flows through the surface of the heating unit 2, and then bends under the action of the guide unit 5 and flows through the heat sink 3 from two different directions through the first flow channel 51 and the second flow channel 52 respectively. This can make the components in the housing 1 more compact.

[0090] As feasible, Figures 1 to 3As shown, the heating unit 2 and the heat sink 3 can be installed on the partition unit 6, and heat exchange can be performed between the heat sink 3 and the heating unit 2. The partition unit 6 has a first connecting port 61 and a second connecting port 62 connecting the first space 7 and the second space 8. The first connecting port 61 forms part of the first flow channel 51, and the second connecting port 62 forms part of the second flow channel 52. The air flowing into the second space 8 passes through the third flow channel 81 and then respectively passes through the first connecting port 61 and the second connecting port 62 to enter the first space 7, and then flows through the first flow channel 51 and the second flow channel 52 respectively and flows through the heat sink 3 from two different directions.

[0091] In the above embodiment, the heating unit 2 and the heat sink 3 may be disposed opposite to each other. The heat sink 3 may be located in the first space 7 or in the partition unit 6. When the heat sink 3 is located in the partition unit 6, the partition unit 6 may have a greater thickness and may have a hollow structure or a flow channel structure.

[0092] In the above embodiment, if Figures 1 to 3 As shown, the first flow channel 51 and the second flow channel 52 are both located upstream of the fan 4. With this structure, the suction force generated by the fan 4 during operation can introduce the air outside the housing 1 into the first flow channel 51 and the second flow channel 52 upstream of the fan 4 through the third flow channel 81, so as to flow through the heat sink 3 from two different directions.

[0093] In some embodiments, Figure 3 As shown, the air guide unit 5 may include: a first air guide 53 disposed at the first connecting port 61 and located in the first space 7, the first air guide 53 and the partition unit 6 forming at least a portion of the first flow channel 51; a second air guide 54 disposed at the second connecting port 62 and located in the first space 7, the second air guide 54 and the partition unit 6 forming at least a portion of the second flow channel 52. The air passing through the first connecting port 61 and the second connecting port 62 is respectively guided by the first air guide 53 and the second air guide 54 to respectively pass through the first flow channel 51 and the second flow channel 52, so as to be subsequently directed and concentrated to blow toward the heat sink 3 from two different directions, thereby increasing the air volume and flow rate, and further improving the heat exchange effect.

[0094] In some embodiments, at least a portion of the first flow channel 51 formed by the first flow guide 53 and the partition unit 6 is oriented toward an end of the fin portion 32 close to the body 31. And / or, at least a portion of the second flow channel 52 formed by the second flow guide 54 and the partition unit 6 is oriented toward an end of the fin portion 32 close to the body 31. The temperature of the end of the fin portion 32 close to the body 31 is relatively high. The above method can enhance the heat dissipation of the end of the fin portion 32 close to the body 31, and can also enhance the heat dissipation of the first surface of the body 31, which can improve the heat exchange effect as a whole.

[0095] In some embodiments, the outlet of the second air guide 54 is located at one end of the plurality of fins 32, so that the second flow channel 52 is connected to the gaps between the fins 32. In this way, the air blown out from the outlet of the second air guide 54 can flow to the gaps between the fins 32 as much as possible, so as to increase the air volume and flow rate, thereby improving the heat exchange effect.

[0096] Further, such as Figure 3 As shown, the height of the first area 321 of the plurality of fin parts 32 is lower than the height of the remaining areas. The second guide 54 extends to the upper end surface of the first area 321 of the plurality of fin parts 32 so that the second flow channel 52 partially overlaps with the gap between the fin parts 32. In the above manner, the air blown out from the outlet of the second guide 54 can all flow to the gap between the fin parts 32 to increase the air volume and flow rate, thereby improving the heat exchange effect. Furthermore, when the air flows through the first area 321 of the fin part 32, there is basically no leakage and diffusion, which can further enhance the heat exchange effect between the first area 321 of the fin part 32 and the air.

[0097] In some embodiments, in order to increase the wind volume and wind speed of the air after it flows out of the first guide member 53 and the second guide member 54 through the first communication port 61 and the second communication port 62 respectively, Figure 8 FIG. 1 is a schematic diagram of a structure in which a fan is arranged at the connecting port of the partition unit in an embodiment of the utility model. Figure 8 As shown, a first fan may be provided at the first connecting port 61, and a second fan may be provided at the second connecting port 62. The first fan and the second fan may be located in the second space 8. The first fan is used to blow the air in the second space 8 further into the first connecting port 61. The second fan is used to blow the air in the second space 8 further into the second connecting port 62. The heat exchange effect between the air and the heat sink 3 may be further improved in the above manner.

[0098] When the air-cooled heat dissipation device is a heat pump device, in some embodiments, the air-cooled heat dissipation device may include: a compressor 9; a first heat exchanger 17; a throttling unit; a second heat exchanger 13 having a first heat exchange channel and a second heat exchange channel, the first heat exchange channel is used to receive the refrigerant after passing through the compressor 9, the first heat exchanger 17 and the throttling unit, and the refrigerant flowing through the first heat exchange channel can exchange heat with the fluid flowing through the second heat exchange channel; a water pump 12 arranged in the second space 8, and the water pump 12 can be connected to the second heat exchange channel. The compressor 9, the throttling unit, the second heat exchanger 13 and the water pump 12 can all be arranged in the housing 1, for example, they can be arranged in the second space 8 in the housing 1, and the first heat exchanger 17 can be formed in the vacant part of the housing 1 to facilitate the heat exchange of the first heat exchanger 17. Through the above method, the compressor 9, the throttling unit, the second heat exchanger 13, the first heat exchanger 17 and the water pump 12 and other components are concentrated in one device, so that the heat pump device is integrated and miniaturized, and the heat pump device can directly output the fluid after heat exchange with the refrigerant.

[0099] In the above manner, the second heat exchanger is in a cooling state.

[0100] In other feasible embodiments, the air-cooled heat dissipation device may include a switching valve. The switching valve may be disposed in the second space 8. By switching the switching valve, the second heat exchanger may be switched between a heating state and a cooling state. When the second heat exchanger is in the heating state, the first heat exchanger 17 is used to receive the refrigerant after passing through the compressor 9, the first heat exchange channel and the throttling unit.

[0101] As a feasible method, other components, such as various connecting pipelines, switching valves, etc., can be arranged in the middle of the second space 8, so as to achieve reasonable utilization of the second space 8 and further reduce the volume of the air-cooled heat dissipation device.

[0102] As feasible, Figure 4 This is a partial structural diagram of the air-cooling heat dissipation device at the sound insulation box and the water pump in the embodiment of the utility model (part of the side panels of the sound insulation box are not shown). Figure 5 This is a schematic diagram of the position of the expansion water tank in one embodiment of the utility model. Figure 6 This is a schematic diagram of the position of the expansion water tank in another embodiment of the utility model. Figure 7 FIG. 1 is a schematic diagram of the position of the second heat exchanger in a feasible implementation mode in the embodiment of the utility model. Figures 4 to 7As shown, the water pump 12 is located in the third flow channel 81, and the heating unit 2 is located downstream of the water pump 12. The water pump 12 is used to output the fluid that flows through the second heat exchange flow channel and exchanges heat with the refrigerant flowing through the first heat exchange flow channel, so as to supply the terminal device. The terminal device can be a fan 4 coil, floor heating, wall heating, capillary network, chilled beam, etc. When the heat pump device is in a cooling state, the water pump 12 outputs a low-temperature fluid. Therefore, when the air flows through the third flow channel 81, it can exchange heat with the wall of the water pump 12, thereby further reducing the temperature of the air, and then improving the heat dissipation effect of the air on the heating unit 2 and the heat sink 3.

[0103] In some embodiments, Figure 5 As shown, the air-cooled heat dissipation device may further include: an expansion water tank 15 connected to the second heat exchange flow channel, the expansion water tank 15 is located in the third flow channel 81, and the heating unit 2 is located downstream of the expansion water tank 15. Similarly, when the heat pump device is in a cooling state, the temperature of the fluid stored in the expansion water tank 15 is relatively low. Therefore, when the air flows through the third flow channel 81, it can exchange heat with the wall surface of the expansion water tank 15, thereby further reducing the temperature of the air, thereby improving the heat dissipation effect of the air on the heating unit 2 and the heat sink 3.

[0104] In some embodiments, Figures 4 to 7 As shown, the air-cooled heat dissipation device may include: a soundproof box 10 arranged in the second space 8, the soundproof box 10 having a top plate 101, a bottom plate 102 and a side plate 103 around a circle. The compressor 9 is arranged in the soundproof box 10. The soundproof box 10 is used to soundproof the compressor 9, thereby reducing the decibel of the noise emitted by the heat pump device that the user can hear. A noise reduction and sound insulation layer may be provided on the side wall of the soundproof box 10 to further absorb the noise emitted by the compressor 9. In addition, a hollow interval is formed between the soundproof box 10 and the outer shell 1, and the interval can also play a certain noise reduction role. The soundproof box 10 and the outer shell 1 can be connected together by a fixed connection, for example, the bottom plate 102 and the bottom wall of the outer shell 1 are fixedly connected by bolts, screws, etc. The entire soundproof box 10 can have sufficient strength and stability, and the water pump 12 can be arranged on the top plate 101. The water pump 12 can be fixed on the top plate 101, so that the water pump 12 is arranged in the second space 8 along the vertical direction, making full use of the space of the second space 8. As a feasible method, part of the side plate 103 of the soundproof box 10 can include part of the partition unit 6, so that the use amount of the side plate 103 can be saved. As a feasible method, Figure 7 As shown, the soundproof box 10 and the second heat exchanger 13 can be arranged side by side in the lower part of the second space 8.

The partition 14 divides the upper part of the second space 8 into a second space first subspace 82 and a second space second subspace 83 arranged in the front-to-back direction. The partition 14 may be connected and fixed to the partition unit 6, or may be connected and fixed to the housing 1. The first communication port 61 and the second communication port 62 on the partition unit 6 are connected to the second space second subspace 83.

The control panel 16 may be mounted on the partition 14 and located in the first subspace 82 of the second space, and the heat dissipation element 18 for heat exchange with the control panel 16 is located in the second subspace 83 of the second space. Alternatively, the control panel 16 is mounted on the partition 14 and located in the second subspace 83 of the second space. In this way, before the air flows into the first connecting port 61 and the second connecting port 62, it will also pass through the control panel 16 or the heat dissipation element 18, thereby cooling the control panel 16.

[0107] As a feasible method, the air cooling device may include: an expansion water tank 15. In some embodiments, such as Figure 6 As shown, the expansion tank 15 can be arranged in the second subspace 83 of the second space.

At this time, preferably, the expansion water tank 15 can adopt a flat, long strip structure, which is conducive to optimizing the volume of the air-cooled heat dissipation device.

[0108] As feasible, Figure 7 As shown, the air-cooled heat dissipation device may include: a liquid storage tank 19, which is used to store refrigerant. The liquid storage tank 19 may be arranged in the second space 8. In order to improve the utilization rate of the second space 8, the liquid storage tank 19 may be located behind the soundproof box 10. The liquid storage tank 19 may extend in a vertical direction and be arranged in parallel with the second heat exchanger 13. The liquid storage tank 19 may be connected between the throttling unit and the second heat exchanger 13. As a feasible method, Fig. 9 This is a schematic diagram of the structure of the second heat exchanger in the embodiment of the utility model. Fig.10 for Fig. 9 A partial enlarged view of Fig.11 for Fig.10A cross-sectional view of the connection interface, such as Figures 9 to 11 As shown, the second heat exchanger 13 may include at least one connection interface 131 for connection and a temperature measuring unit 132. The connection interface 131 is connected to the first heat exchange channel or the second heat exchange channel. For example, the second heat exchanger 13 may include a shell 133, in which the first heat exchange channel and the second heat exchange channel are formed. The shell 133 is connected with a connection interface 131. The connection interface 131 is used to connect other devices or components or pipes to the second heat exchanger 13. The connection interface 131 can be generally a pipe, and an opening 1311 is opened on the side wall of the pipe. The temperature measuring piece of the temperature measuring unit 132 is inserted into the opening 1311 and fixed by a pressing plate 134 and a fastener 135 for fixing the pressing plate 134. Through the above structure, the second heat exchanger 13 can have a temperature measurement function, and the setting method of the temperature measuring unit 132 is simple and convenient, easy to maintain, and low in cost.

[0109] Specifically, if Fig.11 As shown, the inner wall of the opening 1311 has a step portion, and a seal 136 can be provided between the temperature measuring member and the step portion in the insertion direction. The temperature measuring member presses the seal 136 so that the seal 136 is pressed against the step portion, thereby achieving a seal between the temperature measuring member and the tube body. The fixed pressing plate 134 has an opening, and the tail of the temperature measuring member is inserted into the opening. The fixed pressing plate 134 can press against the temperature measuring member to prevent the temperature measuring member from falling out, while ensuring that the temperature measuring member presses the seal 136. The fastener 135 passes through the fixed pressing plate 134 and is screwed into the side wall of the tube body, thereby achieving the fixing of the fixed pressing plate 134.

[0110] In the above embodiment, the temperature measuring unit 132 may also be replaced by a pressure measuring unit, and its principle is similar to that of the temperature measuring unit 132. In addition, the second heat exchanger 13 may be various types of heat exchangers, which are not limited in this application, such as a plate heat exchanger, a tube heat exchanger, etc.
