Detailed implementation manners

[0045] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0046] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0047] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0048] In this application, unless otherwise clearly stipulated and defined, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In this application, unless otherwise clearly stipulated and defined, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0051] In the related art, generally, heat dissipation is carried out on heat-generating devices such as the batteries of energy storage devices through a thermal management system. However, the noise of the thermal management system in the related art is relatively large.

[0052] Through research, it is found that the thermal management system in the related art includes a condenser for dissipating heat from the battery and a fan for dissipating heat from the condenser. The fan needs to be arranged close to the condenser to dissipate heat from the condenser, which results in a relatively high noise in the thermal management system of the related art.

[0053] To solve the problem of relatively high noise in the thermal management system of the related art, this application designs a thermal management system that uses a non-fan heat dissipation method to dissipate heat from the cooler. While effectively dissipating heat from the heat-generating device, it can also reduce the noise of the thermal management system.

[0054] Figure 1 The structural schematic diagram of the thermal management system in an embodiment of this application is shown.

[0055] Please refer to Figure 1 , an embodiment of this application provides a thermal management system 10 for dissipating heat from a heat-generating device 20. The heat-generating device 20 has a coolant channel (not shown in the figure) so that the coolant in the thermal management system 10 can flow into the coolant channel, and then dissipate heat from the heat-generating device 20. Among them, the coolant can be a refrigerant, and the model of the refrigerant can be R134A or R410A.

[0056] The heat-generating device 20 may include but is not limited to at least one of a battery cluster 21, an energy storage power station power conversion device 22, and an electric heating element 23.

[0057] It may be that there is 1 heat-generating device 20. For example, the heat-generating device 20 includes a battery cluster 21. Another example is that the heat-generating device 20 includes an energy storage power station power conversion device 22; or the heat-generating device 20 includes an electric heating element 23.

[0058] Of course, it may also be that there are at least two heat-generating devices 20, and the coolant channels on multiple heat-generating devices 20 are connected in series and / or in parallel to the following heat dissipation system 100. For example, there are three heat-generating devices 20, and the coolant channels on two of the heat-generating devices 20 are connected in series (the two heat-generating devices 20 are respectively a battery cluster 21 and an electric heating element 23), and then are connected in parallel to the heat dissipation system 100 with another heat-generating device 20.

[0059] The thermal management system 10 includes a heat dissipation system 100 and a noise-reducing heat dissipation mechanism 200. The heat dissipation system 100 is connected to the heat-generating device 20 to dissipate heat from the heat-generating device 20. Specifically, the heat dissipation system 100 includes a cooler 110, and the cooler 110 has a first heat exchange channel H1 for dissipating heat from the heat-generating device 20.

[0060] It is possible that the heating device 20 is provided with one first heat exchange channel H1 for dissipating heat from the heating device 20. Alternatively, the heating device 20 may be provided with at least two first heat exchange channels H1 for dissipating heat from at least two heating devices 20.

[0061] The noise-reducing heat dissipation mechanism 200 is disposed on one side of the cooler 110 for dissipating heat from the cooler 110.

[0062] The noise-reducing heat dissipation mechanism 200 refers to a heat dissipation component that dissipates heat from the cooler 110 by using a low-noise heat dissipation method (such as a non-fan heat dissipation method).

[0063] The noise-reducing heat dissipation mechanism 200 can dissipate heat from the cooler 110 by using a liquid cooling heat dissipation method. For example, the cooler 110 can be sprayed with a coolant, or the cooler 110 can be placed in a liquid storage container filled with a coolant. The noise-reducing heat dissipation mechanism 200 can also use a phase change material to absorb the heat on the outer wall of the cooler 110 or other heat exchange methods with the outer wall of the cooler 110 to absorb the heat on the outer wall of the cooler 110, and no specific limitation is made here.

[0064] In this way, when the thermal management system 10 operates, the first heat exchange channel H1 of the cooler 110 can be used to absorb the heat generated by the heating device 20, so as to dissipate heat from the heating device 20 by using the first heat exchange channel H1 of the cooler 110. The heating device 20 can be well dissipated. In addition, during the process of using the noise-reducing heat dissipation mechanism 200 to dissipate heat from the cooler 110, the problem of relatively large noise caused by the fan dissipating heat from the condenser can be avoided, and the noise of the thermal management system 10 can also be reduced.

[0065] In some embodiments, the heat dissipation system 100 further includes a heat exchanger 120 and a fourth pump 130. The heat exchanger 120 has a third heat exchange channel H3 and a fourth heat exchange channel H4 for heat exchange with the third heat exchange channel H3. The heat exchanger 120 is connected to the heating device 20 through the fourth pump 130, and the coolant channel is connected to the third heat exchange channel H3. The first heat exchange channel H1 is connected to the fourth heat exchange channel H4.

[0066] Thus, when the thermal management system 10 operates, since the coolant channel is connected to the third heat exchange channel H3, heat generated by the heat generating device 20 can be absorbed by the coolant channel and the third heat exchange channel H3. Considering that the third heat exchange channel H3 can exchange heat with the fourth heat exchange channel H4, and the fourth heat exchange channel H4 is connected to the first heat exchange channel H1, the cooler 110 can be used to dissipate heat from the third heat exchange channel H3 and the coolant channel. Thus, heat dissipation of the heat generating device 20 can be well achieved. In addition, during the process of using the noise reduction type heat dissipation mechanism 200 to dissipate heat from the cooler 110, the problem of relatively high noise caused by the fan dissipating heat from the condenser can be avoided, and the noise of the thermal management system 10 can also be reduced.

[0067] In some embodiments, the cooler 110 further has a second heat exchange channel H2 capable of exchanging heat with the first heat exchange channel H1. The noise reduction type heat dissipation mechanism 200 includes a first liquid storage container 210. The first liquid storage container 210 has a first chamber Q1. The first liquid storage container 210 is connected to the cooler 110 through a first pump 300. The first chamber Q1 is connected to the second heat exchange channel H2.

[0068] Optionally, the cooler 110 can be selected as a plate cooler or a shell and tube cooler.

[0069] Optionally, the first pump 300 can be externally disposed relative to the heat dissipation system 100, and the influence of the first pump 300 on the noise of the thermal management system 10 can be ignored. Of course, this application is not limited thereto. A first sound insulation member 310 can also be sleeved on the first pump 300. While the first sound insulation member 310 does not affect the operation of the first pump 300, it can also reduce the noise of the first pump 300.

[0070] Thus, the cold water in the first chamber Q1 of the first liquid storage container 210 can be pumped into the second heat exchange channel H2 through the first pump 300 to exchange heat with the coolant in the first heat exchange channel H1. Thus, heat dissipation of the cooler 110 can be well achieved. Further, the cooler 110 can be well utilized to dissipate heat from the heat generating device 20. In addition, noise reduction design can be carried out on the first pump 300 as needed. For example, the first pump 300 can be externally disposed relative to the heat dissipation system 100, or a first sound insulation member 310 can be sleeved on the first pump 300, effectively reducing the noise of the thermal management system 10.

[0071] Optionally, the first liquid storage container 210 can be a user liquid storage container.

[0072] Thus, after the cold water in the second heat exchange channel H2 exchanges heat with the coolant in the first heat exchange channel H1, it can be heated to hot water and collected in the first liquid storage container 210. Further, the water heated by the cooler 110 can also be used as user hot water, realizing the diversified utilization of energy.

[0073] In some other embodiments, please refer to Figure 1 and Figure 2 , the cooler 110 includes a cooler body 111 and a plurality of heat dissipation fins 112 provided on the cooler body 111, and a first heat exchange channel H1 is provided inside the cooler body 111. The noise reduction type heat dissipation mechanism 200 includes a second liquid storage container 220, the second liquid storage container 220 has a second cavity Q2, and at least a part of the heat dissipation fins 112 is located inside the second cavity Q2.

[0074] It may be that all of the heat dissipation fins 112 are located inside the second cavity Q2; or it may be that a part of the heat dissipation fins 112 is located inside the second cavity Q2.

[0075] In this way, the cooling water (which can be tap water) in the second liquid storage container 220 can be used to dissipate heat from the plurality of heat dissipation fins 112, and then the heat on the cooler body 111 can be taken away, and then the cooler 110 can be used to dissipate heat from the heat generating device 20 well. In addition, the noise of the second liquid storage container 220 is very small and can be ignored. Therefore, the noise of the thermal management system 10 can also be reduced well.

[0076] In this embodiment, the cooler body 111 is provided inside the second cavity Q2. The thermal management system 10 further includes a connecting pipe 140. One end of the connecting pipe 140 is communicated with the first heat exchange channel H1, and the other end of the connecting pipe 140 penetrates outside the second cavity Q2 and is communicated with the fourth heat exchange channel H4. The part of the connecting pipe 140 penetrating through the side wall of the second cavity Q2 is hermetically connected to the side wall of the second cavity Q2.

[0077] On the one hand, by arranging the cooler body 111 inside the second cavity Q2 and combining with at least a part of the heat dissipation fins 112 being arranged inside the second cavity Q2, therefore, the cooling water in the second liquid storage container 220 can be better used to absorb the heat on the cooler 110, and then the cooler 110 can be better used to dissipate heat from the heat generating device 20. On the other hand, since the part of the connecting pipe 140 penetrating through the side wall of the second cavity Q2 is hermetically connected to the side wall of the second cavity Q2, the sealing performance of the second cavity Q2 can be improved while satisfying the communication between the fourth heat exchange channel H4 and the first heat exchange channel H1, and then the cooler 110 can be better cooled.

[0078] In this embodiment, the noise reduction type heat dissipation mechanism 200 further includes a third liquid storage container 230. The third liquid storage container 230 has a third cavity Q3. The third liquid storage container 230 is connected to the second liquid storage container 220 through a second pump 400, and the third cavity Q3 is communicated with the second cavity Q2.

[0079] Specifically, the third liquid storage container 230 can be a user liquid storage container.

[0080] In this way, after the cooling water in the second chamber Q2 absorbs the heat on the cooler 110, it can heat the water in the third chamber Q3 to achieve the diversified utilization of energy. For example, the third liquid storage container 230 can provide hot water for users.

[0081] In addition, noise reduction design can be carried out on the second pump 400 as needed. For example, the second pump 400 can be externally arranged relative to the heat dissipation system 100, or a second sound insulation member 410 can be sleeved on the second pump 400, which can effectively reduce the noise of the thermal management system 10.

[0082] In still other embodiments, please refer to Figure 3 , the noise reduction type heat dissipation mechanism 200 includes a cold storage tank 240 and a phase change material layer 250. The cold storage tank 240 has a cold storage chamber 241, the cooler 110 is arranged in the cold storage chamber 241, and the phase change material layer 250 is arranged between the outer wall of the cooler 110 and the chamber wall of the cold storage chamber 241.

[0083] In this way, the latent heat of phase change of the phase change material in the phase change material layer 250 can be used to absorb the heat of the cooler 110. At the same time, during the phase change process, the temperature of the phase change material in the phase change material layer 250 can remain stable, which is beneficial to improving the stability of the heat dissipation power of the cooler 110, so that the thermal management system 10 can operate more safely and stably. In addition, by using the noise reduction type heat dissipation mechanism 200, the noise of the thermal management system 10 can also be reduced.

[0084] In still other embodiments, please refer to Figure 4 , the noise reduction type heat dissipation mechanism 200 includes a cooling tower 260. The cooling tower 260 has a heat exchange chamber 261, and the cooler 110 is arranged in the heat exchange chamber 261.

[0085] In this way, the outer wall of the cooler 110 can exchange heat with the gas in the heat exchange chamber 261. The gas in the heat exchange chamber 261 can be used to take away the heat of the cooler 110, and the gas in the heat exchange chamber 261 can be heated, so that the gas in the heat exchange chamber 261 can better exchange heat with the liquid sprayed in the cooling tower 260. While the cooling tower 260 is operating, the cooler 110 can also be dissipated, so as to better use the cooler 110 to dissipate heat from the heat generating device 20. Of course, the present application is not limited to this. The outer wall of the cooler 110 can also be sprayed with the liquid sprayed in the cooling tower 260 to dissipate the cooler 110.

[0086] Optionally, the coolers 110 of multiple heat dissipation systems 100 can be arranged in the same heat exchange chamber 261.

[0087] In this way, the cooling tower 260 can be used to dissipate heat from the coolers 110 of multiple heat dissipation systems 100 at the same time. Also, multiple coolers 110 can be used to evaporate the liquid sprayed in the cooling tower 260 to better realize the operation of the cooling tower 260.

[0088] In some other embodiments, please refer to Figure 5 , the noise reduction type heat dissipation mechanism 200 includes a nozzle 270 and a third pump 280. The third pump 280 has a coolant inlet (not shown in the figure). The nozzle 270 has a liquid inlet communicating with the coolant inlet and a spray outlet communicating with the liquid inlet. The spray outlet is arranged facing the outer wall of the cooler 110.

[0089] The coolant can be tap water. For example, the coolant inlet is communicated with a faucet, and the third pump 280 can be used to pump the coolant to the nozzle 270. Of course, the present application is not limited to this. The pump can also be connected to a container filled with coolant, and the third pump 280 can also be used to pump the coolant to the nozzle 270.

[0090] In this way, the third pump 280 can pump the coolant to the nozzle 270. Then, the coolant can be sprayed from the spray outlet of the nozzle 270 towards the outer wall of the cooler 110, so as to dissipate heat from the cooler 110 well. Furthermore, the cooler 110 can be used to dissipate heat from the heat generating device 20 well.

[0091] In addition, the third pump 280 can be designed for noise reduction as needed. For example, the third pump 280 is externally arranged relative to the heat dissipation system 100, or a third sound insulation member (not shown in the figure. It can be understood correspondingly with reference to the first sound insulation member 310 and the second sound insulation member 410) is sleeved on the third pump 280, which can effectively reduce the noise of the heat management system 10.

[0092] In this embodiment, the noise reduction type heat dissipation mechanism 200 further includes a fourth liquid storage container 290. The fourth liquid storage container 290 has a fourth chamber Q4 for accommodating the coolant. One end of the third pump 280 where the coolant inlet is provided extends into the coolant in the fourth chamber Q4.

[0093] The fourth liquid storage container 290 can be a user liquid storage container.

[0094] In this way, after the coolant sprayed from the spray outlet of the nozzle 270 exchanges heat with the outer wall of the cooler 110, it can be heated to hot water and then collected in the fourth liquid storage container 290. Furthermore, the water heated by the cooler 110 can also be used as user hot water, realizing the diversified utilization of energy.

[0095] In some embodiments, the heat dissipation system 100 further includes a gas-liquid separator 150, a throttler 160, and a compressor 170. The gas-liquid separator 150 has a liquid flow inlet 1501, a gas flow outlet 1502, and a gas-liquid separation chamber 1503 that is respectively communicated with the liquid flow inlet 1501 and the gas flow outlet 1502. The throttler 160 has a throttling channel (not shown in the figure), and the compressor 170 has a compression channel (not shown in the figure). Wherein, one end of the fourth heat exchange channel H4 is communicated with the liquid flow inlet 1501, the gas flow outlet 1502 is communicated with one end of the first heat exchange channel H1 through the compression channel, and the other end of the first heat exchange channel H1 is communicated with the other end of the fourth heat exchange channel H4 through the throttling channel.

[0096] Specifically, the heat exchanger 120 is an evaporative plate heat exchanger.

[0097] In this way, the coolant in the fourth heat exchange channel H4 can absorb the heat generated by the heat generating device 20, so that the coolant is heated to a high-temperature liquid, and part of the high-temperature liquid evaporates into a high-temperature gas. This part of the high-temperature liquid and high-temperature gas can enter the gas-liquid separation chamber 1503 of the gas-liquid separator 150 through the liquid flow inlet 1501, and then gas-liquid separation can be realized. The high-temperature gas then flows into the compression channel of the compressor 170 through the gas flow outlet 1502, and then can be compressed into a high-temperature and high-pressure gas by the compressor 170. Then this part of the high-temperature and high-pressure gas is condensed into a low-temperature and high-pressure liquid by the cooler 110, and this part of the low-temperature and high-pressure liquid is then transformed into a low-temperature and low-pressure liquid through the throttling channel and flows back into the fourth heat exchange channel H4 again. In this way, by using the heat management system 10 of the present application, the heat generated by the heat generating device 20 can be continuously absorbed, and due to the setting of the gas-liquid separator 150, the situation of damaging the compressor 170 caused by the liquid flowing into the compressor 170 can be reduced.

[0098] In some embodiments, the heat dissipation system 100 further includes a filter 180, and the filter 180 is arranged on the communication pipeline between the first heat exchange channel H1 and the throttling channel.

[0099] In this way, the filter 180 can be used to filter the liquid flowing from the first heat exchange channel H1 into the throttling channel, and the situation of blocking the throttler 160 can be reduced.

[0100] An embodiment of the present application further provides an energy storage device, including the heat management system 10 and the heat generating device 20 in any of the above embodiments.

[0101] As Figure 6 shown, the energy storage device includes a heat generating device 20. As Figure 1 shown, the energy storage device includes at least two heat generating devices 20, and the heat management system 10 can be used to dissipate heat from all the heat generating devices 20.

[0102] While the heat management system 10 can effectively dissipate heat from the heat-generating device 20, it can also reduce the noise of the heat management system 10.

[0103] In some embodiments, the energy storage device includes two heat-generating devices 20, and the coolant channels of the two heat-generating devices 20 are connected in series or in parallel to the heat dissipation system 100. Specifically, the coolant channels of the two heat-generating devices 20 are connected in series or in parallel to the third heat exchange channel H3.

[0104] In some embodiments, the energy storage device includes at least three heat-generating devices 20, and the coolant channels of the at least three heat-generating devices 20 are connected in series and / or in parallel to the heat dissipation system 100 so that the first heat exchange channel H1 can dissipate heat from all the heat-generating devices 20. Specifically, the coolant channels of the at least three heat-generating devices 20 are connected in series and / or in parallel to the third heat exchange channel H3.

[0105] It can be, as Figure 7 shown, the coolant channels of at least two heat-generating devices 20 are connected in series to the heat dissipation system 100. Specifically, the coolant channels of at least two heat-generating devices 20 are connected in series to the third heat exchange channel H3.

[0106] It can also be, as Figure 8 shown, the coolant channels of at least two heat-generating devices 20 are connected in parallel to the heat dissipation system 100. Specifically, the coolant channels of at least two heat-generating devices 20 are connected in parallel to the third heat exchange channel H3. It can also be, as Figure 1 shown, there are three heat-generating devices 20. The coolant channels on two of the heat-generating devices 20 are arranged in series (the two heat-generating devices 20 are the battery cluster 21 and the electric heating element 23 respectively), and then are connected in parallel to the coolant channel of another heat-generating device 20 to the heat dissipation system 100. Specifically, the coolant channels on two of the heat-generating devices 20 are arranged in series, and then are connected in parallel to the coolant channel of another heat-generating device 20 to the third heat exchange channel H3.

[0107] In this way, the first heat exchange channel H1 can dissipate heat from the coolant in the coolant channels of all the heat-generating devices 20, and thus can dissipate heat from all the heat-generating devices 20.

[0108] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0109] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
