[0043] 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 FIG. is a schematic structural diagram of the air-cooled heat dissipation device in an embodiment of the present invention. Figure 2 FIG. is a schematic structural diagram of the air-cooled heat dissipation device in an embodiment of the present invention from another angle. Figure 3 is Figure 1 the enlarged schematic diagram at I in, as Figures 1 to 3 shown, the air-cooled heat dissipation device may include: a housing 1; a heating unit 2; a heat dissipation member 3 for dissipating heat from the heating unit 2; a fan 4 and a flow guiding unit 5 disposed in the housing 1, and the flow guiding unit 5 forms a first flow channel 51 and a second flow channel 52; the fan 4 can introduce the air outside the housing 1 into the interior of the housing 1 and, under the action of the flow guiding unit 5, flow through the first flow channel 51 and the second flow channel 52 respectively and flow through the heat dissipation member 3 from two different directions.

[0044] In this application, first, the heat dissipation component 3 is used to dissipate heat from the heat generating unit 2, thereby reducing the temperature of the heat generating unit 2. Secondly, the fan 4 in the air-cooled heat dissipation device is used to introduce the air outside the housing 1 into the interior of the housing 1. Thus, 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 flow guiding unit 5, the air flows through the first flow channel 51 and the second flow channel 52 respectively and flows through the heat dissipation component 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 regions of the heat dissipation component 3, avoiding the situation where some regions of the heat dissipation component 3 cannot exchange heat with air at a sufficient flow rate, resulting in the insufficient exertion of its heat dissipation performance, and further improving the heat dissipation effect of the heat dissipation component 3.

[0045] To better understand the air-cooled heat dissipation device in this application, the following will further explain and illustrate it. As Figures 1 to 3 shown, the air-cooled heat dissipation device may include: a housing 1, a heat generating unit 2, a heat dissipation component 3, a fan 4, a flow guiding unit 5, etc. Among them, the housing 1 is used to accommodate the heat generating unit 2, the heat dissipation component 3, the fan 4, the flow guiding unit 5 and other components, etc., playing a role in protection and rain prevention, etc. The heat generating unit 2 can be various electronic components, which will generate heat during operation, causing its own temperature to rise. If it cannot be cooled in time, its performance will be affected. As a feasible option, the air-cooled heat dissipation device can be a heat pump device, and the heat generating unit 2 can be a device that generates heat and causes the temperature to rise during the operation of the heat pump device. For example, it can be a control unit in the heat pump device, an inverter for controlling the compressor 9, etc. Correspondingly, the air-cooled heat dissipation device may include: a compressor 9; an inverter electrically connected to the compressor 9.

[0046] As Figures 1 to 3 shown, the heat dissipation component 3 is used to dissipate heat from the heat generating unit 2, thereby reducing the temperature of the heat generating unit 2. The heat dissipation component 3 can be radiators with various different structures, which can be in close contact with the heat generating unit 2 to achieve efficient heat conduction, or can achieve efficient heat conduction with the heat generating unit 2 through a heat conducting material. The heat conducting material can be materials such as heat conducting silicone grease, or it can be a heat conducting plate with a high heat conduction coefficient arranged between the heat generating unit 2 and the heat dissipation component 3, such as a metal plate. The metal plate can also play a role in fixing the heat generating unit 2 and the heat dissipation component 3 at the same time.

[0047] As Figures 1 to 3As shown, the fan 4 and the flow guiding unit 5 are arranged inside the housing 1. The flow guiding 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 flow guiding unit 5, it flows through the first flow channel 51 and the second flow channel 52 respectively, so that the air flowing into the housing 1 flows through the heat dissipation member 3 from two different directions. By allowing the air to blow towards the heat dissipation member 3 from different directions, different regions of the heat dissipation member 3 can fully exchange heat with the air, so as to further improve the heat dissipation effect of the heat dissipation member 3. If the air blows towards the heat dissipation member 3 from only one direction, the speed of the air will decrease when it flows through the heat dissipation member 3. Especially when the air flows through the latter half region of the heat dissipation member 3, the air flow rate is already very low, and the heat exchange rate between the air and the heat dissipation member 3 will be greatly reduced. At this time, the heat dissipation performance of this part of the region of the heat dissipation member 3 cannot be fully utilized.

[0048] As a feasible solution, as Figure 3 shown, the heat dissipation member 3 can include a body 31 having opposite first and second surfaces; a plurality of fin portions 32 located on the first surface of the body 31. In one way, the second surface of the body 31 can be in contact with the heating unit 2 for heat conduction. In another way, the second surface of the body 31 and the heating unit 2 are in heat conduction through a heat-conducting material. The plurality of fin portions 32 are arranged at intervals along a first direction and extend along a second direction.

[0049] The air flowing through the first flow channel 51 can flow through the fin portions 32 from the first direction.

[0050] To achieve the above purpose, as a feasible solution, as Figure 3 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 enable 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.

[0051] The air flowing through the second flow channel 52 can flow through the gap between the fin portions 32 from the second direction, so as to minimize the resistance of the fin portions 32 to the air as much as possible, so that the air can flow through a longer distance of the fin portions 32 at a relatively high speed, so as to improve the heat exchange effect with the fin portions 32.

[0052] There can be an included angle between the first direction and the second direction, and this included angle can enable the air flowing through the first flow channel 51 and the second flow channel 52 to flow through the heat dissipation member 3 from two completely different directions, so that the air flows through different regions of the heat dissipation member 3 that are relatively far apart. In this application, no specific limitation is imposed on the specific angle of this included angle.

[0053] In a specific embodiment, the first direction may be perpendicular to the second direction. In a feasible embodiment, as Figure 3 shown, the first direction may be the vertical direction and the second direction may be the horizontal direction. In another feasible embodiment, the first direction may be the horizontal direction and the second direction may be the vertical direction.

[0054] In another specific embodiment, the first direction may be opposite to the second direction. The air flowing through the first flow channel 51 flows along the first direction from the first end of the fin portion 32 through the fin portion 32. The air flowing through the second flow channel 52 flows along the second direction from the second end of the fin portion 32 through the fin portion 32, and the first end and the second end of the fin portion 32 are oppositely arranged. 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 regions of the fin portion 32 can fully exchange heat with the air, thereby further improving the heat dissipation effect of the heat sink 3.

[0055] As feasible, as Figure 1 and Figure 2 shown, the air-cooled heat dissipation device may include: a partition unit 6, and the partition unit 6 divides the interior of the housing 1 into a first space 7 and a second space 8. An air inlet 11 may be provided on the housing 1 of the second space 8, and the second space 8 forms a third flow channel 81, and the third flow channel 81 communicates the air inlet 11 with the first flow channel 51 and the second flow channel 52. The heating unit 2 is disposed in the second space 8, and the fan 4 is disposed 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 after passing through the third flow channel 81, it flows through the first flow channel 51 and the second flow channel 52 respectively in two different directions under the action of the diversion unit 5 and flows through the heat sink 3. Further, the heating unit 2 may be disposed 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.

[0056] In some embodiments, as Figure 2 shown, one of the directions in which the air flows at the heat sink 3 is generally the same as the extending direction of the heat sink 3, specifically flowing in the vertical direction. The direction in which the air flows at the heating unit 2 is generally the same as the extending direction of the heating unit 2, specifically flowing 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 diversion unit 5 and respectively passes through the first flow channel 51 and the second flow channel 52 and flows through the heat sink 3 in two different directions. This can make the components in the housing 1 more compact.

[0057] As feasible, as 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 occur between the heat sink 3 and the heating unit 2. The partition unit 6 has a first communication port 61 and a second communication port 62 that connect the first space 7 and the second space 8. The first communication port 61 forms part of the first flow channel 51, and the second communication 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 enters the first space 7 through the first communication port 61 and the second communication port 62 respectively. After that, 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.

[0058] In the above embodiment, the heating unit 2 and the heat sink 3 can be arranged back to back. The heat sink 3 can 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 can have a relatively large thickness, which can have a hollow structure or a flow channel structure.

[0059] In the above embodiment, as Figures 1 to 3 shown, both the first flow channel 51 and the second flow channel 52 are located upstream of the fan 4. With this structure, the suction force generated when the fan 4 operates 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.

[0060] In some embodiments, as Figure 3 shown, the flow guiding unit 5 can include: a first flow guiding member 53 disposed at the first communication port 61 and located in the first space 7, and the first flow guiding member 53 and the partition unit 6 form at least part of the first flow channel 51; a second flow guiding member 54 disposed at the second communication port 62 and located in the first space 7, and the second flow guiding member 54 and the partition unit 6 form at least part of the second flow channel 52. The air after passing through the first communication port 61 and the second communication port 62 is respectively guided by the first flow guiding member 53 and the second flow guiding member 54 to respectively concentrate and pass through the first flow channel 51 and the second flow channel 52, so as to be subsequently directed and concentrated to blow towards the heat sink 3 from two different directions, thereby increasing the air volume and flow rate, and further improving the heat exchange effect.

[0061] In some embodiments, at least part of the first flow channel 51 formed by the first flow guiding member 53 and the partition unit 6 faces the end of the fin portion 32 close to the body 31. And / or, at least part of the second flow channel 52 formed by the second flow guiding member 54 and the partition unit 6 faces the end of the fin portion 32 close to the body 31. The temperature at the end of the fin portion 32 close to the body 31 is relatively high. Through the above method, the heat dissipation at the end of the fin portion 32 close to the body 31 can be enhanced, and the heat dissipation of the first surface of the body 31 can also be enhanced. Overall, the heat exchange effect can be improved.

[0062] In some embodiments, the outlet of the second deflector 54 is located at one end of the plurality of fin portions 32, so that the gap between the second flow channel 52 and the fin portions 32 is communicated. In this way, the air blown out from the outlet of the second deflector 54 can flow to the gap between the fin portions 32 as much as possible, so as to increase the air volume and flow rate of the air, and further improve the heat exchange effect.

[0063] Further, as Figure 3 shown, the height of the first region 321 of the plurality of fin portions 32 is lower than the height of the remaining regions. The second deflector 54 extends to the upper end surface of the first region 321 of the plurality of fin portions 32, so that the gap between the second flow channel 52 and the fin portions 32 partially overlaps. In this way, the air blown out from the outlet of the second deflector 54 can all flow to the gap between the fin portions 32, so as to increase the air volume and flow rate of the air, and further improve the heat exchange effect. Further, when the air flows through the first region 321 of the fin portions 32, there is basically no leakage and diffusion, which can further strengthen the heat exchange effect between the first region 321 of the fin portions 32 and the air.

[0064] In some embodiments, in order to enhance the air volume and air speed of the air flowing out from the first deflector 53 and the second deflector 54 through the first communication port 61 and the second communication port 62 respectively, Figure 8 The structural schematic diagram of the fan provided at the communication port of the partition unit in the embodiment of the present utility model is shown in Figure 8 as shown, a first fan can be provided at the first communication port 61, and a second fan can be provided at the second communication port 62. The first fan and the second fan can be located in the second space 8. The first fan is used to further blow the air in the second space 8 into the first communication port 61. The second fan is used to further blow the air in the second space 8 into the second communication port 62. In this way, the heat exchange effect between the air and the heat sink 3 can be further improved.

[0065] 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 flow path and a second heat exchange flow path, the first heat exchange flow path being configured 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 flow path being capable of exchanging heat with the fluid flowing through the second heat exchange flow path; a water pump 12 disposed in the second space 8, the water pump 12 being capable of communicating with the second heat exchange flow path. The compressor 9, the throttling unit, the second heat exchanger 13, the water pump 12, etc. may all be disposed in the housing 1, for example, in the second space 8 within the housing 1, and the first heat exchanger 17 may be formed in the vacant portion of the housing 1 to facilitate heat exchange of the first heat exchanger 17. In the above manner, components such as the compressor 9, the throttling unit, the second heat exchanger 13, the first heat exchanger 17, and the water pump 12 are all centrally arranged in one device, thereby making the heat pump device integrated and miniaturized, and the heat pump device can directly output the fluid after heat exchange with the refrigerant outward.

[0066] In the above manner, the second heat exchanger is in a refrigeration state.

[0067] 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 can be switched between a heating state and a refrigeration state. When the second heat exchanger is in the heating state, the first heat exchanger 17 is configured to receive the refrigerant after passing through the compressor 9, the first heat exchange flow path and the throttling unit.

[0068] As feasible, other components may be disposed in the middle of the second space 8, such as various connecting pipelines, switching valves, etc., so as to achieve reasonable utilization of the second space 8 and further reduce the volume of the air-cooled heat dissipation device.

[0069] As feasible, Figure 4 This is a partial structural schematic diagram of the air-cooled heat dissipation device at the sound insulation box and the water pump in the embodiment of the present utility model (the side plates of part of the sound insulation box are not shown), Figure 5 This is a schematic diagram of the position of the expansion tank in one embodiment of the embodiment of the present utility model, Figure 6 This is a schematic diagram of the position of the expansion tank in another embodiment of the embodiment of the present utility model, Figure 7 This is a schematic diagram of the position of the second heat exchanger in one feasible embodiment of the embodiment of the present utility model, such as 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 has flowed through the second heat exchange flow channel and exchanged heat with the refrigerant flowing through the first heat exchange flow channel for use by the terminal equipment. The terminal equipment can be a fan coil 4, floor heating, wall heating, capillary network, chilled beam, etc. When the heat pump device is in the refrigeration state, the water pump 12 outputs a low-temperature fluid. Therefore, when air flows through the third flow channel 81, it can exchange heat with the wall surface of the water pump 12, thereby further reducing the temperature of the air and further improving the heat dissipation effect of the air on the heating unit 2 and the heat dissipation member 3.

[0070] In some embodiments, as Figure 5 shown, the air-cooled heat dissipation device may further include: an expansion tank 15 communicated with the second heat exchange flow channel. The expansion tank 15 is located in the third flow channel 81, and the heating unit 2 is located downstream of the expansion tank 15. Similarly, when the heat pump device is in the refrigeration state, the temperature of the fluid stored in the expansion tank 15 is relatively low. Therefore, when air flows through the third flow channel 81, it can exchange heat with the wall surface of the expansion tank 15, thereby further reducing the temperature of the air and further improving the heat dissipation effect of the air on the heating unit 2 and the heat dissipation member 3.

[0071] In some embodiments, as Figures 4 to 7 shown, the air-cooled heat dissipation device may include: a sound insulation box 10 disposed in the second space 8. The sound insulation box 10 has a top plate 101, a bottom plate 102, and side plates 103 surrounding it for one week. The compressor 9 is disposed in the sound insulation box 10. The sound insulation box 10 is used to sound-insulate 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 sound insulation box 10 to further absorb the noise emitted by the compressor 9. In addition, a hollow interval is formed between the sound insulation box 10 and the outer shell 1, and this interval can also play a certain role in noise reduction. The sound insulation box 10 and the outer shell 1 may be connected together by a fixed connection method. For example, the bottom plate 102 and the bottom wall of the outer shell 1 are fixedly connected by bolts, screws, etc. The entire sound insulation box 10 may have sufficient strength and stability, and the water pump 12 may be disposed on the top plate 101. The water pump 12 may be fixed on the top plate 101, so as to realize the vertical arrangement of the water pump 12 in the second space 8 and make full use of the space of the second space 8. As an alternative, part of the side plate 103 of the sound insulation box 10 may include part of the partition unit 6, so that the usage amount of the side plate 103 can be saved. As an alternative, as Figure 7 shown, the sound insulation box 10 and the second heat exchanger 13 may be arranged in parallel in the lower part of the second space 8. For example, the sound insulation box 10 is close to the front of the air-cooled heat dissipation device, and the second heat exchanger 13 is close to the rear of the air-cooled heat dissipation device.

The partition 14 may be fixedly connected to the separation unit 6 or may be fixedly connected to the housing 1. The first communication port 61 and the second communication port 62 on the separation unit 6 communicate with the second sub-space 83 of the second space.

[0073] As an alternative, as Figure 8 shown in the figure, the air-cooled heat dissipation device may include: a control panel 16, which is a circuit board for controlling the air-cooled heat dissipation device. The control panel 16 may be installed on the partition 14 and located in the first sub-space 82 of the second space, and a heat dissipation element 18 for exchanging heat with the control panel 16 is located in the second sub-space 83 of the second space. Alternatively, the control panel 16 is installed on the partition 14 and located in the second sub-space 83 of the second space. In this way, before the air flows into the first communication port 61 and the second communication port 62, it will also pass through the control panel 16 or the heat dissipation element 18, thereby cooling the control panel 16.

[0074] As an alternative, the air-cooled heat dissipation device may include: an expansion tank 15. In some embodiments, as Figure 6 shown in the figure, the expansion tank 15 may be disposed in the second sub-space 83 of the second space. At this time, preferably, the expansion tank 15 may adopt a barrel-shaped structure. In some embodiments, there are two fans 4 arranged vertically, and the expansion tank 15 is installed on the separation unit 6 and located on the side between the two fans 4 in the first space 7. In some embodiments, as Figure 5 shown in the figure, the expansion tank 15 may be disposed at the lower part of the second space 8, for example, arranged in parallel with the sound insulation box 10 and the second heat exchanger 13, and may be disposed on the right side of the sound insulation box 10 or the second heat exchanger 13. At this time, preferably, the expansion tank 15 may adopt a flat and long strip-shaped structure, which is beneficial to optimizing the volume of the air-cooled heat dissipation device.

[0075] As an alternative, as Figure 7 shown in the figure, the air-cooled heat dissipation device may include: a liquid storage tank 19 for storing refrigerant. The liquid storage tank 19 may be disposed 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 sound insulation box 10. The liquid storage tank 19 may extend in the 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 an alternative, Figure 9 This is a schematic structural diagram of the second heat exchanger in the embodiment of the present invention. Figure 10 is Figure 9 a partial enlarged view in Figure 11 is Figure 10Cross-sectional view of the connection interface, as Figures 9 to 11 shown, the second heat exchanger 13 may include at least one connection interface 131 for connection and a temperature measurement unit 132. The connection interface 131 communicates with the first heat exchange flow channel or the second heat exchange flow channel. For example, the second heat exchanger 13 may include a housing 133, and a first heat exchange flow channel and a second heat exchange flow channel are formed inside the housing 133. The connection interface 131 is connected to the housing 133. The connection interface 131 is used for other devices or components or pipe bodies to be connected to the second heat exchanger 13. The connection interface 131 may generally be a pipe body, and an opening 1311 is formed on the side wall of the pipe body. The temperature measuring element of the temperature measurement unit 132 is inserted into the opening 1311, and the temperature measuring element is 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 self-contained temperature measurement function, and the setting method of the temperature measurement unit 132 is simple and convenient, facilitating maintenance and having a low cost.

[0076] Specifically, as Figure 11 shown, a step portion is provided at the inner side wall of the opening 1311, and a seal 136 may be provided between the temperature measuring element and the step portion in the insertion direction. The temperature measuring element presses the seal 136 so that the seal 136 abuts against the step portion, thereby realizing the seal between the temperature measuring element and the pipe body. The fixing pressing plate 134 has an opening, and the tail of the temperature measuring element is inserted into the opening. The fixing pressing plate 134 can abut against the temperature measuring element to prevent the temperature measuring element from falling out, and at the same time ensure that the temperature measuring element presses the seal 136. The fastener 135 passes through the fixing pressing plate 134 and is screwed into the side wall of the pipe body, thereby realizing the fixation of the fixing pressing plate 134.

[0077] In the above embodiment, the temperature measurement unit 132 may also be replaced with a pressure measurement unit, and its principle is similar to that of the temperature measurement unit 132. In addition, the second heat exchanger 13 may be various types of heat exchangers, and no limitation is imposed on it in this application, such as plate heat exchangers, tubular heat exchangers, and the like.

[0078] In this application, a heat pump system is also proposed. The heat pump system includes: an air-cooled heat dissipation device as described in any of the above; a terminal device, and the terminal device is used to receive the fluid output by the second heat exchange flow channel under the action of the water pump 12.
