Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of battery temperature control, and in particular to an aluminum plate heat exchanger and a temperature control energy storage system. Background Art

[0002] Energy storage liquid cooling technology is a heat dissipation technology for battery energy storage systems that uses liquid as a medium. Compared with traditional air cooling methods, energy storage liquid cooling technology has better heat dissipation effects, can effectively improve the operating efficiency and life of the battery system, and can also reduce noise and vibration, improve the overall performance of the battery system, and can still operate normally in low-temperature environments; at the same time, energy storage liquid cooling technology requires less space and can better adapt to various complex environments, such as outdoor environments and high-altitude areas.

[0003] The coolant in the battery can exchange heat with the refrigerant in a plate heat exchanger. The plate heat exchangers in current energy storage systems are usually made of stainless steel, but stainless steel plate heat exchangers are heavy and expensive. Aluminum plate heat exchangers are generally used in the field of on-board energy storage. Due to the large number of energy storage battery packs in a car, the flow rate of the coolant is relatively large. Generally, a 5-8kw battery unit requires a flow rate of 50L / min, while the flow rate requirement of the aluminum plate heat exchanger is generally less than or equal to 30L / min. If it exceeds 30L / min, there is a risk of leakage or corrosion erosion, which affects the service life. Utility Model Content

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The terms used in the embodiments of this utility model are for the purpose of describing specific embodiments only and are not intended to limit this utility model. It should be noted that the terms "first" and "second" are used for descriptive purposes only and do not indicate any order, quantity, or importance. They are simply used to distinguish different components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] Figure 1 This is a schematic diagram of the structure of an aluminum plate heat exchanger provided by the embodiment of the utility model. Figure 1 The aluminum plate heat exchanger 01 includes a first sub-heat exchanger 110 and a second sub-heat exchanger 120; the first sub-heat exchanger 110 includes a first refrigerant inlet 131, a first refrigerant outlet 132, a first water-cooling inlet 151 and a first water-cooling outlet 152; the second sub-heat exchanger 120 includes a second refrigerant inlet 141, a second refrigerant outlet 142, a second water-cooling inlet 161 and a second water-cooling outlet 162; the first water-cooling inlet 151 and the second water-cooling inlet 161 are connected in parallel to the total water-cooling inlet 191; the first water-cooling outlet 152 and the second water-cooling outlet 162 are connected in parallel to the total water-cooling outlet 192.

[0034] For example, the first and second sub-heat exchangers 110 and 120 are constructed from a series of stacked corrugated metal plates. These plates form thin rectangular channels, allowing heat exchange between the plates. The refrigerant and coolant flow through their respective channels, exchanging heat with adjacent plates to achieve heat exchange. The refrigerant's temperature increases after passing through the first and second sub-heat exchangers 110 and 120, while the coolant's temperature decreases after passing through the first and second sub-heat exchangers 110 and 120. The refrigerant cools the coolant, cooling it.

[0035] The first refrigerant inlet 131, first refrigerant outlet 132, second refrigerant inlet 141, and second refrigerant outlet 142 are used for the flow of refrigerant. The first water-cooling inlet 151, first water-cooling outlet 152, second water-cooling inlet 161, and second water-cooling outlet 162 are used for the flow of coolant. The flow rate of aluminum plate heat exchanger 01 is equal to the sum of the flow rates of first sub-heat exchanger 110 and second sub-heat exchanger 120. For example, if the flow rate of aluminum plate heat exchanger 01 is 50 L / min, the flow rates of first sub-heat exchanger 110 and second sub-heat exchanger 120 can both be 25 L / min.

[0036] The aluminum plate heat exchanger provided in the embodiment of the present invention can divide the flow of the coolant in the aluminum plate heat exchanger into two by connecting the first water-cooling inlet and the second water-cooling inlet in parallel, and the first water-cooling outlet and the second water-cooling outlet in parallel. Without changing the total flow of the coolant, the flow in each sub-heat exchanger can be reduced, making each sub-heat exchanger less likely to leak or corrode and erode. This is beneficial to increasing the flow of the aluminum plate heat exchanger and extending its service life.

[0037] Optional, continue to refer to Figure 1 The area of ​​the first water-cooling inlet 151 is larger than that of the first refrigerant inlet 131; the area of ​​the first water-cooling outlet 152 is larger than that of the first refrigerant outlet 132; the area of ​​the second water-cooling inlet 161 is larger than that of the second refrigerant inlet 141; and the area of ​​the second water-cooling outlet 162 is larger than that of the second refrigerant outlet 142. This helps increase the coolant flow rate, meeting larger coolant flow requirements, and also facilitates better absorption and transfer of heat, achieving efficient heat exchange performance.

[0038] Optional, continue to refer to Figure 1 The first refrigerant inlet 131 and the second refrigerant inlet 141 are connected in parallel to the main refrigerant inlet 101 ; the first refrigerant outlet 132 and the second refrigerant outlet 142 are connected in parallel to the main refrigerant outlet 102 .

[0039] For example, each refrigerant inlet generally requires an electronic expansion valve to change from a high-pressure state to a low-pressure state to absorb heat and produce a cooling effect. By connecting the refrigerant inlets and refrigerant outlets of the first sub-heat exchanger 110 and the second sub-heat exchanger 120 in parallel, the refrigerant inlets of the first sub-heat exchanger 110 and the second sub-heat exchanger 120 can share an electronic expansion valve, which is conducive to simplifying the structure and reducing temperature control costs.

[0040] Optional, continue to refer to Figure 1 The area of ​​the first refrigerant outlet 132 is larger than the area of ​​the first refrigerant inlet 131; the area of ​​the second refrigerant outlet 142 is larger than the area of ​​the second refrigerant inlet 141. Specifically, the larger aperture of the refrigerant outflow sub-heat exchanger facilitates the refrigerant outflow from the sub-heat exchanger, accelerates the flow of the refrigerant, and thus improves heat exchange efficiency.

[0041] Optional, continue to refer to Figure 1 The first and second sub-heat exchangers 110, 120 are positioned adjacent to each other, with a gap provided between them. This gap compensates for thermal expansion of the first and second sub-heat exchangers 110, 120, addressing thermal expansion and contraction, and preventing collisions between the first and second sub-heat exchangers 110, 120, which could cause wear and tear and shorten their service life.

[0042] Optional, continue to refer to Figure 1 The total water-cooling inlet 191 is located at the center between the first water-cooling inlet 151 and the second water-cooling inlet 161 ; the total water-cooling outlet 192 is located at the center between the first water-cooling outlet 152 and the second water-cooling outlet 162 .

[0043] Specifically, the distance between the main water-cooling inlet 191 and the first water-cooling inlet 151 is equal to the distance between the main water-cooling inlet 191 and the second water-cooling inlet 161, and the distance between the main water-cooling outlet 192 and the first water-cooling outlet 152 is equal to the distance between the main water-cooling outlet 192 and the second water-cooling outlet 162. This allows coolant to flow evenly from the main water-cooling inlet 191 into the first and second sub-heat exchangers 110 and 120, facilitating balanced flow rates across the sub-heat exchangers and preventing excessive flow rates in some sub-heat exchangers from affecting the service life of the aluminum plate heat exchanger 01.

[0044] Optional, Figure 2 This is a schematic diagram of the structure of another aluminum plate heat exchanger provided by the embodiment of the utility model, referring to Figure 2 The aluminum plate heat exchanger 01 also includes a third sub-heat exchanger 130; the third sub-heat exchanger 130 includes a third refrigerant inlet (not shown in the figure), a third refrigerant outlet (not shown in the figure), a third water-cooling inlet 171 and a third water-cooling outlet 172.

[0047] In this way, the path lengths of the coolant flowing from the water-cooling main inlet 191 into the water-cooling inlets (151, 161, 171) of each sub-heat exchanger can be made equal, and the path lengths of the coolant flowing from the water-cooling inlets (152, 162, 172) of each sub-heat exchanger to the water-cooling main outlet 192 can be made equal, which is beneficial to increasing the coolant flow rate of the aluminum plate heat exchanger 01 and balancing the coolant flow rate in each sub-heat exchanger, avoiding a large flow rate in some sub-heat exchangers, which affects the service life of the aluminum plate heat exchanger 01.

[0049] The first water-cooling inlet 151 and the second water-cooling inlet 161 are connected in parallel to the first intermediate inlet 201, and the first intermediate inlet 201 is located at the center between the first water-cooling inlet 151 and the second water-cooling inlet 161; the third water-cooling inlet 171 and the fourth water-cooling inlet 181 are connected in parallel to the second intermediate inlet 301, and the second intermediate inlet 301 is located at the center between the third water-cooling inlet 171 and the fourth water-cooling inlet 181; the first intermediate inlet 201 and the second intermediate inlet 301 are connected in parallel to the main water-cooling inlet 191, and the main water-cooling inlet 191 is located at the center between the first intermediate inlet 201 and the second intermediate inlet 301.
