Technical Field

[0002] Some equipment or devices require constant heat exchange when working to maintain stability and continuity of operation, especially batteries. As batteries are used more and more widely, temperature has an important impact on batteries. If the temperature is too high or too low, the battery may experience thermal runaway, severe life attenuation, and charging and discharging restrictions. Battery heat exchange has become a problem that must be solved. Current battery thermal management mainly includes: wind heat exchange, liquid heat exchange, thermoelectric heat exchange, heat pipe heat exchange, and phase change material thermal management. Among them, liquid heat exchange is widely used because of its low cost and good heat exchange effect.

[0003] The core components of the liquid heat exchange system are heat exchange plates, heat exchange tubes and other heat exchange parts that are in direct contact with the battery cells. Traditional heat exchange pipes are only in a single inlet and outlet form, and the temperature of the final liquid outlet will be higher or lower, resulting in reduced heat exchange efficiency.

[0052] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0053] In order to meet different power requirements, the battery may include multiple battery cells, wherein the multiple battery cells may be connected in series, in parallel, or in a hybrid connection, wherein the hybrid connection refers to a mixture of series and parallel connections. Optionally, multiple battery cells may be connected in series, in parallel, or in a hybrid connection to form a battery module, and multiple battery modules may be connected in series, in parallel, or in a hybrid connection to form a battery. In other words, multiple battery cells may be directly formed into a battery, or may be first formed into a battery module, and the battery module may then be formed into a battery. The battery is further disposed in an electrical device to provide electrical energy to the electrical device.

[0054] The battery may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, etc., which is not limited in the embodiments of the present application. The battery may be cylindrical, flat, rectangular or other shapes, etc., which is not limited in the embodiments of the present application. Batteries are generally divided into three types according to the packaging method: cylindrical batteries, square batteries and soft-pack batteries.

[0055] Batteries of any shape or connected in any form will generate heat during use. If the heat is too high, it will have an adverse effect on the performance and service life of the battery. In the relevant technology, a heat exchange system can be set to exchange heat for the battery. The heat exchange system can be an air heat exchange system or a liquid heat exchange system.

[0056] The liquid heat exchange system uses heat exchange liquid as a heat exchange carrier, and uses liquid pumps and heat exchange pipes to complete the flow of heat exchange liquid in the battery system. It is divided into direct contact and indirect contact. Direct contact heat exchange is to immerse the battery pack directly in the heat exchange liquid; indirect contact heat exchange is to arrange heat exchange pipes between battery modules or arrange heat exchange components in the battery pack, and the heat exchange pipes are in direct contact with the battery modules or the heat exchange components are in direct contact with the batteries in the battery pack, and the heat is absorbed by the liquid in the heat exchange pipes or heat exchange components to remove heat.

[0057] The heat exchange system may include heat exchange plates, and the surfaces of the multiple heat exchange plates are in contact with the surfaces of the batteries. During use, for example, heat exchange fluid flows through the heat exchange plates, thereby removing heat from the batteries and cooling the batteries. The heat exchange plates have heat exchange channels inside, and the heat exchange fluid flows in the heat exchange channels.

[0058] Alternatively, the heat exchange system may further include a heat exchange tube, in which a heat exchange fluid flows, and directly contacts the battery through the heat exchange tube to achieve heat exchange, thereby achieving a cooling effect on the battery.

[0059] However, no matter whether heat exchange is performed in the form of heat exchange plates or heat dissipation is performed in the form of heat exchange tubes, in the related technologies, a one-in-one-out form is adopted, that is, a setting with only one liquid inlet and only one liquid outlet is adopted. This makes the overall length of the heat exchange tube or heat exchange channel larger, and the temperature of the liquid inside the tube body at the end changes more greatly than that at the beginning, which cannot meet the heat exchange requirements at the end well, thereby reducing the heat exchange efficiency.

[0060] Based on the above considerations, the embodiment of the present application provides a heat exchange component 10 to improve the heat exchange efficiency to a certain extent and reduce the temperature difference between the starting end and the ending end of the heat exchange tube 11.

[0061] The heat exchange assembly 10 provided in the embodiment of the present application includes at most a plurality of heat exchange tubes 11. Since the number of heat exchange tubes 11 is increased, the length of each heat exchange tube 11 can be shortened while the heat exchange area of ​​the battery 100 remains unchanged, so that the liquid temperature at the end of a single heat exchange tube 11 does not change too much, thereby increasing the heat exchange efficiency.

[0062] The heat exchange assembly 10 provided in this embodiment can be applied to a heat exchange system, and further to a battery 100, and an electrical device using the battery 100 as a power source or various energy storage systems using the battery 100 as an energy storage element. The electrical device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, an electric airplane toy, and the like, and the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, and the like.

[0063] The battery 100 disclosed in the embodiment of the present application can be used in, but not limited to, electrical devices such as vehicles 1000, ships or aircraft. A power supply system having the heat exchange assembly 10, heat exchange system and battery 100 disclosed in the present application can be used, which is beneficial to improving the heat exchange effect of the battery, and improving the stability of the performance of the battery 100 and the life of the battery 100.

[0064] For the convenience of description, the following embodiments are described by taking the electric device provided in the embodiments of the present application as a vehicle 1000 as an example.

[0065] Please refer to Figure 1 , Figure 1A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery 100 may be used to power the vehicle 1000, for example, the battery 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0066] In some embodiments of the present application, the battery 100 can not only serve as an operating power source for the vehicle 1000, but also serve as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0067] In some embodiments of the present application, the battery 100 may include a box, a battery cell and a heat exchange system, wherein the battery cell is contained in the box. The box is used to provide a containing space for the battery cell, and the box may adopt a variety of structures.

[0068] The battery cell may be a secondary battery or a primary battery, wherein a secondary battery refers to a battery cell that can be used continuously by activating the active material by charging after the battery cell is discharged, and a primary battery refers to a battery cell that cannot be used continuously by activating the active material by charging after the power of the battery cell is exhausted. The battery cell may also be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, etc., but is not limited thereto. The battery cell may be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes, wherein the prismatic battery cell includes a square-shell battery cell, a blade-shaped battery cell, a polygonal prismatic battery, and a polygonal prismatic battery is, for example, a hexagonal prismatic battery, etc., and the present application has no particular restrictions.

[0069] In some embodiments, the heat exchange system may include a heat exchange component 10 and a pump body, a heat exchanger, etc. for driving the flow.

[0070] The pump body is used to drive the flow of the heat exchange fluid, so that it reciprocates through the heat exchange component 10 and continuously exchanges heat with the battery 100. After passing through the battery 100, the heat exchange fluid flows to the heat exchanger, and the temperature of the heat exchange fluid is adjusted again so that it can be used again.

[0071] According to some embodiments of the present application, please refer to 2. Figure 3 , Figure 4 and Figure 5 , discloses a heat exchange assembly 10, which is intended to appropriately improve the heat exchange efficiency of a heat exchange tube 11. The heat exchange assembly 10 provided in this embodiment includes a heat exchange tube 11, a liquid inlet collector 12, a liquid outlet collector 13, a liquid inlet pipe 14, and a liquid outlet pipe 15.

[0072] In order to improve the heat exchange efficiency, the present embodiment provides a plurality of heat exchange tubes 11, and each heat exchange tube 11 is independent of each other, that is, has a relatively independent liquid flow pipeline. The liquid inlet collector 12 is used to connect the liquid inlet of the heat exchange tube 11, the liquid outlet collector 13 is used to connect the liquid outlet of the heat exchange tube 11, the liquid inlet pipe 14 is connected to the liquid inlet collector 12, and the liquid outlet pipe 15 is connected to the liquid outlet collector 13.

[0073] The number of heat exchange tubes 11 can be two or more, and each heat exchange tube 11 is relatively independent, that is, they are not connected to each other and work independently, so that the liquid flowing into a certain heat exchange tube 11 will not flow into other heat exchange tubes 11, and will pass through the heat exchange tube 11 alone, so the path of the liquid flow is relatively short, and the temperature change of the liquid will not be too large in the tail section of the tube body compared with the head section, so that the battery 100 corresponding to the tail section of the tube body can be better heat exchanged. It should be noted that since the area of ​​the heat exchange part of the battery 100 is certain, it can be specifically the side, bottom or large surface of the battery 100. Therefore, when multiple heat exchange tubes 11 are used, the length of a single heat exchange tube 11 can be shortened, thereby appropriately improving the heat exchange efficiency.

[0074] In some cases, the number of heat exchange tubes 11 may be more than two, and may be three, four, six, eight, etc. The factors determining the number of heat exchange tubes 11 include not only the heat exchange surface area of ​​the battery 100, but also the density of the heat exchange tubes 11. If rapid heat dissipation is required and the gap between the tubes is small, the number of heat exchange tubes 11 may be increased.

[0075] A plurality of heat exchange tubes 11 need to perform liquid supply and liquid discharge operations at the same time, so correspondingly, the present embodiment also includes a liquid inlet collector 12 and a liquid outlet collector 13. The collector is a structure with an inner cavity, which is used to connect the liquid inlet tube 14 or the liquid outlet tube 15. For the liquid inlet collector 12, liquid is injected into the liquid inlet collector 12 through the liquid inlet tube 14, and then the liquid inlet collector 12 injects liquid into the heat exchange tube 11. After the liquid flows through the heat exchange tube 11, it flows to the liquid outlet collector 13, injects liquid into the inner cavity of the liquid outlet collector 13, and then flows to the liquid outlet tube 15 through the liquid outlet collector 13, realizing the final circulation process. Therefore, the liquid inlet collector 12 can be connected to the liquid inlet of the heat exchange tube 11, and the liquid outlet collector 13 can be connected to the liquid outlet of the heat exchange tube 11. In general, the liquid inlet of the heat exchange tube 11 provided in this embodiment can be set at one end of the heat exchange tube 11 in the length direction, and the liquid outlet can be set at the other end of the heat exchange tube 11 in the length direction.

[0076] The number of the inlet current collector 12 and the outlet current collector 13 can be set as needed. One inlet current collector 12 or outlet current collector 13 can be connected to multiple heat exchange tubes 11, or one inlet current collector 12 or outlet current collector 13 can be connected to one heat exchange tube 11 respectively.

[0077] In some cases, the heat exchange liquid provided in this embodiment can be a coolant, whose temperature is lower than the surface temperature of the battery 100. When it flows through the heat exchange surface of the battery 100, it can absorb heat from the battery 100, thereby ensuring that the battery 100 continues to work within a certain temperature range. Alternatively, the heat exchange liquid can also be a liquid with a higher temperature, which is used to heat the battery 100, especially in some extremely low temperature environments, so that the battery 100 can work within a reasonable temperature range, and the problem of the temperature being too low to affect the efficiency of the battery 100 will not occur.

[0078] According to the embodiments provided in the present application, the effect is that the heat exchange component 10 provided in the present application includes at least two heat exchange tubes 11, and the multiple heat exchange tubes 11 can work independently. Compared with a single heat exchange tube 11, the length of each heat exchange tube 11 will be shortened on the same required heat exchange area, thereby reducing the temperature difference between the liquid in the last section of the heat exchange tube 11 and the liquid in the first section of the tube, and appropriately improving the heat exchange effect.

[0079] In some embodiments, see Figure 2 and Figure 4 , a plurality of heat exchange tubes 11 are located on the first plane 23 .

[0080] Specifically, the present embodiment provides a plurality of heat exchange tubes 11 located on the same plane, and the plane is defined as the first plane 23. The heat exchange tubes 11 extend along a certain direction, specifically on the same plane, so that all the heat exchange tubes 11 are formed on the first plane 23, and when heat exchange is performed, all the heat exchange tubes 11 can be attached to the heat exchange surface of the battery 100, so that the heat exchange effect is better. Therefore, in order to increase the heat exchange efficiency, the present application not only increases the number of heat exchange tubes 11, but also enables all the heat exchange tubes 11 to be attached to the heat exchange surface of the battery 100 through a relatively flat surface.

[0081] The "first" in the first plane 23 does not have any limiting meaning, and is merely a number used to distinguish different planes. The first plane 23 may be a plane parallel to the heat exchange surface of the battery 100, which is convenient for heat dissipation.

[0082] In some embodiments, see Figure 2 , a plurality of heat exchange tubes 11 are symmetrically arranged about a second plane 24, and the second plane 24 is perpendicular to the first plane 23. The present application further provides a second plane 24, and the "second" in the second plane 24 is also only used to distinguish it from other planes, and there is no other limitation.

[0083] Specifically, in order to improve the heat exchange efficiency, the multiple heat exchange tubes 11 provided in this embodiment are arranged in a symmetrical manner about the second plane 24. The second plane 24 is perpendicular to the first plane 23, so when the heat exchange component 10 is in use, the second plane 24 is perpendicular to the heat exchange surface of the battery 100. When specifically arranged, the second plane 24 passes through the center line (i.e., the bisector) of the heat exchange surface, so that the heat exchange tubes 11 of the heat exchange component 10 are symmetrically arranged about the bisector of the heat exchange surface. It is equivalent to that the number and layout of the heat exchange tubes 11 arranged on both sides of the bisector of the heat exchange surface are symmetrical, so that equivalent heat exchange is formed for the areas on both sides of the bisector of the heat exchange surface of the battery 100, which can improve the efficiency of heat exchange to a certain extent.

[0084] In some cases, when the heat exchange surface is rectangular, the bisector may be a line connecting the midpoints of the two long sides of the heat exchange surface, a line connecting the midpoints of the two wide sides of the heat exchange surface, or a diagonal line of the heat exchange surface. The heat exchange tubes 11 are symmetrically arranged on both sides of the bisector.

[0085] According to the embodiment of the present application, since the heat exchange tubes 11 are symmetrically arranged, uniform heat exchange of the battery 100 is achieved, thereby improving the heat exchange efficiency.

[0086] The specific symmetrical arrangement may be in the form of the second plane 24 and the heat exchange tubes 11 not intersecting each other, and the heat exchange tubes 11 being arranged on both sides of the second plane 24; or the second plane 24 and the heat exchange tubes 11 intersecting each other, and the intersecting heat exchange tubes 11 themselves being symmetrical about the second plane 24. Either form can well improve the heat exchange effect.

[0087] In some embodiments, reference Figure 2 The plurality of heat exchange tubes 11 are divided into a first tube group 11a and a second tube group 11b. The number of heat exchange tubes 11 included in the first tube group 11a is the same as the number of heat exchange tubes 11 included in the second tube group 11b. The first tube group 11a and the second tube group 11b are symmetrical about the second plane 24.

[0088] This embodiment preferably provides the second arrangement form mentioned above, that is, the second plane 24 does not intersect with the heat exchange tube 11 .

[0089] The multiple heat exchange tubes 11 are arranged so that the heat exchange tubes 11 can be grouped, specifically into a first tube group 11a and a second tube group 11b. The first tube group 11a includes one or more heat exchange tubes 11, and the second tube group 11b includes one or more heat exchange tubes 11. The number of heat exchange tubes 11 in the first tube group 11a and the second tube group 11b is equal, and the two tube groups are symmetrically arranged about the second plane 24, that is, the corresponding heat exchange tubes 11 in the first tube group 11a and the corresponding heat exchange tubes 11 in the second tube group 11b are symmetrically arranged about the second plane 24. Such a symmetrical arrangement can make the heat exchange effect at various places of the heat exchange surface of the battery 100 more uniform, and there will be no possibility of a large imbalance between cold and hot, that is, the heat exchange effect of the heat exchange tubes 11 located on both sides of the second plane 24 is consistent.

[0090] The effect of adopting a non-intersecting arrangement between the second plane 24 and a single heat exchange tube 11 is that the water flow direction in the heat exchange tubes 11 on both sides of the second plane 24 can also be symmetrical. Specifically, it can be understood that when the heat exchange liquid flows into the two symmetrical heat exchange tubes 11 on both sides of the second plane 24, it can flow in from symmetrical positions at the same time, so that the heat exchange liquid flows symmetrically in the heat exchange tube 11, so that the heat exchange surfaces on both sides of the second plane 24 have the same heat exchange effect, and the overall heat exchange effect of the battery 100 is uniform. When the second plane 24 and a single heat exchange tube 11 intersect each other, the flow direction of the heat exchange liquid flowing in the intersecting heat exchange tube 11 cannot be symmetrical relative to the second plane 24.

[0091] Since the number of heat exchange tubes 11 in the first tube group 11 a and the number of heat exchange tubes 11 in the second tube group 11 b are equal, the number of heat exchange tubes 11 in the heat exchange assembly 10 may be an even number.

[0092] In some embodiments, see Figure 2Since the heat exchange tubes 11 on both sides of the second plane 24 are symmetrical, in order to make the liquid in the heat exchange tubes 11 on both sides flow symmetrically, the embodiment of the present application also provides that the liquid inlet of the heat exchange tubes of the first tube group 11a and the liquid inlet of the heat exchange tubes of the second tube group 11b are symmetrical about the second plane 24, and the liquid outlet of the heat exchange tubes of the first tube group 11a and the liquid outlet of the heat exchange tubes of the second tube group 11b are symmetrical about the second plane 24.

[0093] The liquid in the liquid inlet collector 12 can enter the heat exchange tube 11 through the liquid inlet, and the liquid in the heat exchange tube 11 can enter the liquid outlet collector 13 through the liquid outlet. When the liquid inlets on both sides are aligned with respect to the second plane 24 and the liquid outlets on both sides are symmetrical with respect to the second plane 24, the liquid flows in from symmetrical positions of the heat exchange tube 11 and flows out from symmetrical positions of the heat exchange tube 11 at the same time, thereby achieving symmetrical flow of the heat exchange liquid and thus achieving uniform heat exchange at various positions of the battery 100.

[0094] In some cases, in order to enhance the effect of use, the spacing between each tube section of a single heat exchange tube 11 can be set equal or similar, or the spacing between each heat exchange tube 11 can be set equal or similar and can be equal to the spacing between each tube section of a single heat exchange tube 11, so that the heat exchange effect on the entire surface is balanced.

[0095] In some embodiments, see Figure 5 The liquid inlet collector 12 and the liquid outlet collector 13 are integrated into one.

[0096] Specifically, the liquid inlet current collector 12 and the liquid outlet current collector 13 are integrated into one body, which can effectively save space. It should be noted that the liquid inlet current collector 12 and the liquid outlet current collector 13 are connected to each other through the external surface to form a whole, but their internal spaces are independent of each other, one is used for liquid inlet and the other is used for liquid outlet. The two can be connected by welding or bonding to form a whole. Since the setting space of the battery 100 components is limited, it is necessary to try not to occupy too much space when setting the heat exchange component 10. Therefore, in this embodiment, the liquid inlet current collector 12 and the liquid outlet current collector 13 are set as one body, which can effectively save space.

[0097] Specifically, it can be as follows: when there is one liquid inlet current collector 12 and one liquid outlet current collector 13, the liquid inlet current collector 12 is arranged in contact with the liquid outlet current collector 13; when there is one liquid inlet current collector 12 and multiple liquid outlet current collectors 13, the liquid inlet current collector 12 is arranged in contact with the adjacent liquid outlet current collector 13, and the liquid outlet current collector 13 is arranged in contact with the adjacent liquid outlet current collector 13; when there is one liquid outlet current collector 13 and multiple liquid inlet current collectors 12, the liquid outlet current collector 13 is arranged in contact with the adjacent liquid inlet current collector 12, and the liquid inlet current collector 12 is arranged in contact with the adjacent liquid inlet current collector 12; when there are multiple liquid inlet current collectors 12 and multiple liquid outlet current collectors 13, the liquid inlet current collector 12 is arranged in contact with the adjacent liquid outlet current collector 13 and the adjacent liquid inlet current collector 12, and the liquid outlet current collector 13 is arranged in contact with the adjacent liquid outlet current collector 13.

[0098] In some cases, the liquid inlet current collector 12 and the liquid outlet current collector 13 can be an integrally formed structure, with different inner cavities opened on a block structure for collecting the liquid inlet and the liquid outlet, respectively, which also achieves the technical effect of saving space.

[0099] In some embodiments, see Figure 4 and Figure 5 At least one of the liquid inlet current collector 12 and the liquid outlet current collector 13 is multiple, and the liquid inlet current collector 12 and the liquid outlet current collector 13 are arranged on the same plane and in the same direction.

[0100] Specifically, the plane may be the first plane 23 mentioned above, and the liquid inlet collector 12 and the liquid outlet collector 13 are simultaneously arranged on the first plane 23, and are located on the same plane as the plurality of heat exchange tubes 11, and are arranged on the same plane and arranged in the same direction, so that it is convenient to connect with the heat exchange tubes 11. If the liquid inlet collector 12 and the liquid outlet collector 13 are arranged in two directions, it is inconvenient to connect the heat exchange tubes 11, and in order to make the heat exchange tubes 11 symmetrically arranged, the heat exchange tubes 11 may be bent, which not only fails to improve the heat exchange efficiency, but also complicates the processing of the heat exchange tubes 11.

[0101] In some cases, the inlet current collector 12 and the outlet current collector 13 can be aligned with each other in the arrangement direction to form a flat surface without protrusions or step structures, which facilitates the placement of the inlet current collector 12 and the outlet current collector 13 and improves space utilization.

[0102] In some embodiments, see Figure 4, the liquid inlet current collector 12 and the liquid outlet current collector 13 are arranged alternately in sequence. Specifically, the so-called alternate arrangement in sequence means that in the same direction, a liquid inlet current collector 12 is set, a liquid outlet current collector 13 is set, and a liquid inlet current collector 12 is set. All the liquid inlet current collectors 12 and liquid outlet current collectors 13 are arranged in sequence to form a form of alternate arrangement in sequence. In this way, it is easy to form a situation where the liquid in the heat exchange tube 11 flows symmetrically. If the liquid inlet current collectors 12 are arranged in sequence, and then the liquid outlet current collectors 13 are arranged in sequence, all the liquid inlets are located on one side, and all the liquid outlets are located on the other side of the symmetry. Then, after the heat exchange tube 11 is connected, the flow direction of the liquid in all the heat exchange tubes 11 is from one side to the other side, and a symmetrical flow cannot be formed. When the two are arranged alternately in sequence, a symmetrical flow can be formed after the heat exchange tube 11 is connected, which has a good heat exchange effect and makes the battery 100 heat exchange uniform.

[0103] The inlet current collector 12 and the outlet current collector 13 may also be arranged in this way. In some embodiments, the inlet current collector 12 is arranged on both sides of the outlet current collector 13 , or the outlet current collector 13 is arranged on both sides of the inlet current collector 12 .

[0104] Specifically, it can be arranged in such a way that the liquid outlet collector 13 is arranged in the middle, and the liquid inlet collectors 12 are arranged on both sides of the liquid outlet collector 13, which is also convenient for connecting the heat exchange tube 11, so that the liquid in the heat exchange tube 11 can flow symmetrically. Two liquid outlet collectors 13 can be arranged in the middle, and one liquid inlet collector 12 is arranged on both sides. The heat exchange liquid in the heat exchange tube 11 from the liquid inlet collector 12 on one side flows to the liquid outlet collector 13 adjacent to the liquid inlet collector 12 after passing through the heat exchange tube 11, and the liquid inlet collector 12 on the other side adopts the same flow form, thus forming a symmetrical flow form. Alternatively, the number of the liquid inlet collectors 12, the liquid outlet collectors 13 and the heat exchange tubes 11 can be increased as needed.

[0105] Alternatively, a liquid outlet collector 13 may be provided in the middle position, and a plurality of openings 20 may be provided on the liquid outlet collector 13 to respectively connect a plurality of heat exchange tubes 11 , and then a liquid inlet collector 12 having half the number of openings 20 may be provided on both sides of the liquid outlet collector 13 , and the liquid inlet collectors 12 are connected to the corresponding heat exchange tubes 11 one by one.

[0106] Therefore, the arrangement provided in this embodiment can also form a symmetrical flow of the heat exchange tube 11, so that the heat exchange in each part of the battery 100 is uniform.

[0107] In some embodiments, see Figure 4, there are multiple liquid inlet current collectors 12 that are interconnected, and one of the liquid inlet current collectors 12 has a connecting hole 16 to connect to the liquid inlet pipe 14; and / or, there are multiple liquid outlet current collectors 13 that are interconnected, and one of the liquid outlet current collectors 13 has a connecting hole 16 to connect to the liquid outlet pipe 15.

[0108] Specifically, the inlet current collector 12 and the outlet current collector 13 can accommodate a certain amount of heat exchange liquid, introduce the heat exchange liquid into the heat exchange tube 11 or collect the heat exchange liquid flowing out of the heat exchange tube 11, so as to realize the flow of the heat exchange liquid. The function of the current collector is to collect the heat exchange liquid, then flow the heat exchange liquid into each heat exchange tube 11, and collect the heat exchange liquid in each heat exchange tube 11 for discharge. One inlet current collector 12 or outlet current collector 13 can be connected to multiple heat exchange tubes 11, or one inlet current collector 12 or outlet current collector 13 can be connected to one heat exchange tube 11. When there are multiple inlet current collectors 12 and multiple outlet current collectors 13, in order to save space, multiple inlet current collectors 12 or multiple outlet current collectors 13 are connected in series and interconnected, so that only one inlet pipe 14 or outlet pipe 15 is required. If each inlet current collector 12 or outlet current collector 13 is connected to a separate inlet pipe 14 or outlet pipe 15, multiple inlet pipes 14 or outlet pipes 15 need to be provided, which greatly occupies space. Therefore, the form provided in this embodiment only requires one inlet pipe 14 or outlet pipe 15 to meet the requirements and can greatly save space.

[0109] The liquid inlet pipe 14 and the liquid outlet pipe 15 can be circular tubes, one end of which is connected to the connecting hole 16, and the other end can extend outward to connect the heat exchanger. The liquid inlet pipe 14 and the liquid outlet pipe 15 can be set as straight pipe sections or in a curved form according to the connection direction.

[0110] In some embodiments, see Figure 3 and Figure 5 The non-adjacent liquid inlet current collectors 12 are connected to each other through the guide channel 17 provided in the liquid outlet current collector 13 between them, and the non-adjacent liquid outlet current collectors 13 are connected to each other through the guide channel 17 provided in the liquid inlet current collector 12 between them.

[0111] Based on the number and arrangement of the liquid inlet current collector 12 and the liquid outlet current collector 13, there can be multiple, and the multiple liquid inlet current collectors 12 may not be adjacent to each other, and the multiple liquid outlet current collectors 13 may not be adjacent to each other. In order to enable all the liquid inlet current collectors 12 to be interconnected and all the liquid outlet current collectors 13 to be interconnected, this embodiment provides that non-adjacent liquid inlet current collectors 12 are interconnected through the liquid outlet current collectors 13 therebetween, and non-adjacent liquid outlet current collectors 13 are interconnected through the liquid inlet current collectors 12 therebetween.

[0112] Since the inlet current collector 12 and the outlet current collector 13 are integrated into one, they are connected to each other and extend in the same direction, so there are two non-adjacent inlet current collectors 12 or two non-adjacent outlet current collectors 13. In this case, if an external open pipe is used to connect the two, the setting of the open pipe will undoubtedly increase the space required. Therefore, this embodiment provides a space-saving connection form, which is connected to each other through the adjacent outlet current collectors 13 or the adjacent inlet current collectors 12 themselves. The open pipe does not need to be separately set up to connect, which can greatly save the occupied space. It should be noted that although they are connected to each other through the middle outlet current collector 13 or the inlet current collector 12, the channels or cavities of the outlet current collector 13 and the inlet current collector 12 that contain the heat exchange liquid will not be connected, but relatively independent, that is, the heat exchange liquid of the inlet and the heat exchange liquid of the outlet will not mix.

[0113] Specifically, when the middle is the liquid outlet current collector 13 and the two sides are the liquid inlet current collectors 12, a flow guide channel 17 is opened on the liquid outlet current collector 13, and the liquid inlet current collectors 12 on both sides are connected through the flow guide channel 17. Alternatively, when the middle is the liquid inlet current collector 12 and the two sides are the liquid outlet current collectors 13, a flow guide channel 17 is opened on the liquid inlet current collector 12, and the liquid outlet current collectors 13 on both sides are connected through the flow guide channel 17. After such a form of setting, it is achieved that the two current collectors can be connected without adding additional open pipes, reducing the occupied space of the structure. And the connection through the opening of the flow guide channel 17 has better sealing performance.

[0114] In some embodiments, see Figure 3 , the flow guide channel 17 is located at the bottom of the liquid outlet current collector 13 and / or the liquid inlet current collector 12, the liquid inlet pipe 14 is connected to the top of the liquid inlet current collector 12, and the liquid outlet pipe 15 is connected to the top of the liquid outlet current collector 13. The bottom and top of the present application are relative to the use state. In the use state, the flow guide channel 17 can be located at the bottom of the liquid outlet current collector 13 and / or the liquid inlet current collector 12, because for the convenience of setting, the top of the current collector often needs to be connected to the liquid inlet pipe 14 or the liquid outlet pipe 15. Therefore, the flow guide channel 17 is set at the bottom for convenience.

[0115] In some embodiments, see Figure 3 The liquid inlet collector 12 and / or the liquid outlet collector 13 include a shell, the first wall of the shell is provided with a connecting hole 16 to connect with the liquid inlet pipe 14 or the liquid outlet pipe 15, the second wall of the shell is provided with an opening 20 for connecting with the heat exchange tube 11, and the first wall and the second wall are arranged adjacent to each other.

[0116] Specifically, the present embodiment provides a liquid inlet current collector 12 and / or liquid outlet current collector 13 including a shell, the shell may have an inner cavity, the inner cavity is used to accommodate the heat exchange liquid, the first wall is provided with a connecting hole 16 that can connect to the liquid inlet pipe 14 or the liquid outlet pipe 15, the first wall is generally the top wall of the shell, the second wall of the shell is provided with an opening 20, the opening 20 is used to connect to the heat exchange tube 11, thus forming a complete set of flow pipelines. The second wall may be a side wall of the shell, so that the first wall and the second wall are arranged adjacently, which facilitates the setting of the liquid inlet and liquid outlet of the shell.

[0117] In some embodiments, see Figure 3 The shell includes an opening, and a sealing plate 21 for sealing is welded at the opening, and the sealing plate 21 forms the first wall and / or the second wall.

[0118] The present embodiment provides a composition form of the shell structure of the liquid inlet current collector 12 and / or the liquid outlet current collector 13. For the convenience of processing, a sealing plate 21 is provided. For the processing equipment, the difficulty of processing a through hole in the material is lower than the difficulty of boring a hole in the material. Therefore, when processing the current collector provided in the present embodiment, the material is first processed into a through hole to form a transparent structure with the end as the opening, and then the sealing plate 21 is installed at the opening to form a hollow shell. The sealing plate 21 is installed by welding, which can achieve both sealing and firm connection, so that the connection strength is large. The formation form of the shell provided in the present embodiment makes the processing operation simple and reduces the difficulty of processing.

[0119] The sealing plate 21 is specifically a plate-like structure, which can be made of the same material as the main structure. Its shape is adapted to the opening diameter, and the opening can be completely closed by welding. In addition, the above-mentioned connecting hole 16 and opening 20 can be opened on the sealing plate 21.

[0120] In some embodiments, see Figure 3 and Figure 5 , the plurality of openings 20 are located at the same height and arranged in a line. Specifically, the openings 20 connected to the liquid inlet of the heat exchange tube 11 and the openings 20 connected to the liquid outlet of the heat exchange tube 11 are both at the same height and arranged in a line. This has the effect that after the heat exchange tube 11 is connected, the heat exchange tube 11 can be at the same height, that is, located on the same plane, so that it can fit the heat exchange surface of the battery well.

[0121] In some cases, the opening 20 may be a rectangular hole, and the cross section of the heat exchange tube 11 may be a rectangular shape. By docking the opening 20 with the liquid inlet or the liquid outlet, the connection between the liquid inlet collector 12 and the liquid outlet collector 13 and the heat exchange tube 11 can be achieved. The opening 20 is opened on the shell and connected to the inner cavity of the shell. In order to increase the heat exchange effect, the cross section of the heat exchange tube 11 is set to a rectangular shape, so that the heat exchange tube 11 has a flat outer surface, and when it is in contact with the heat exchange surface of the battery 100, it can be well fitted with the heat exchange surface through the flat surface, thereby increasing the heat exchangeable area and improving the heat exchange efficiency. Therefore, the opening 20 in this embodiment is correspondingly set to a rectangular hole, which is compatible with the heat exchange tube 11, so that good connection can be achieved. The rectangular shape is preferably a rectangle, and the heat exchange surface of the battery 100 is contacted through the large surface of the cuboid.

[0122] The inlet current collector 12 and the outlet current collector 13 may be welded or bonded together. Welding can effectively strengthen the firmness of the connection between the two, so as to form a stable integrated structure. In order to simplify the connection process, the two may not be fully welded, and partial welding may be used. Since there is no separation stress between the two, the partial welding form can also meet the requirements. Alternatively, in some cases, bonding can also be used, and the bonding between the two can be achieved by a viscous glue or the like. The bonding form is simpler and more convenient to operate, and to a certain extent, it can also keep the two in good integrity.

[0123] In some embodiments, the outer surface of the inlet current collector 12 and / or the outlet current collector 13 is a plurality of planes. Specifically, the outer surface of the current collector is a plurality of planes, so that the two can be placed conveniently. In terms of specific structure, the two can adopt a rectangular parallelepiped structure or a cube structure. While the two can be placed conveniently, the rectangular parallelepiped or cube structure is easy to process and shape, and the inner cavity is easy to process.

[0124] The present application also provides a preferred arrangement of the inlet collector 12 and the outlet collector 13 in the heat exchange assembly 10. Figure 2 , Figure 3 and Figure 5Specifically, the heat exchange assembly 10 includes two liquid inlet collectors 12 and a liquid outlet collector 13 disposed between the two liquid inlet collectors 12. The shell of the liquid inlet collector 12 is a first shell 12a, the shell of the liquid outlet collector 13 is a second shell 13a, the opening 20 of the first shell 12a is a first opening 20a, and the opening 20 of the second shell 13a is a second opening 20b; one of the first shells 12a is provided with a connecting hole 16 connected to the liquid inlet pipe 14, and the second shell The body 13a is provided with a connecting hole 16 connected to the liquid outlet pipe 15; the first shell 12a is provided with a liquid inlet cavity 18 inside, and the liquid inlet cavity 18 is connected to the first opening 20a, and one of the liquid inlet cavities 18 of the first shell 12a is also connected to the liquid inlet pipe 14; the second shell 13a is provided with a liquid outlet cavity 19 and a guide channel 17 separated from each other inside, and the liquid outlet cavity 19 is connected to the second opening 20b and the connecting hole 16 and then to the heat exchange tube 11 and the liquid outlet pipe 15, and the guide channel 17 is connected to the two liquid inlet cavities 18. The first opening 20a is connected to the liquid inlet of the heat exchange tube 11, and the second opening 20b is connected to the liquid outlet of the heat exchange tube 11.

[0125] Specifically, the use requirements can be met by using two inlet current collectors 12 and one outlet current collector 13. The two inlet current collectors 12 are arranged on both sides of one outlet current collector 13 and are arranged in close contact. An opening 20 can be arranged on each inlet current collector 12, and two openings 20 can be arranged correspondingly on the outlet current collector 13, that is, there are two first openings 20a in total and two second openings 20b in total, so that a symmetrical conduction can be achieved. For the convenience of setting, one of the two first shells 12a can be connected to the inlet pipe 14.

[0126] The first shell 12a has a liquid inlet cavity 18, and the second shell 13a has a liquid outlet cavity 19 and a flow guide channel 17 that are separated from each other. The specific liquid flow direction is as follows: the heat exchange liquid enters the liquid inlet cavity 18 of a first shell 12a from the liquid inlet pipe 14 through the connecting hole 16, and then the heat exchange liquid is divided into two streams here, one stream enters a heat exchange tube 11 through the first opening 20a, and the other stream enters the liquid inlet cavity 18 of another first shell 12a through the flow guide channel 17, and the heat exchange liquid in the liquid inlet cavity 18 of another first shell 12a enters another heat exchange tube 11 through the first opening 20a, and the heat exchange liquid in the two heat exchange tubes 11 enters the liquid outlet cavity 19 of the liquid outlet collector 13 through the second opening 20b on the second shell 13a, and then flows out through the liquid outlet pipe 15, completing the entire flow process.

[0127] The effect of this embodiment is that the structure is simple and the arrangement is convenient. While using as few current collectors as possible, it not only saves space but also enables good symmetrical flow of the heat exchange fluid, thereby increasing the heat exchange effect.

[0128] For further information, see Figure 3The guide channel 17 is arranged at the lower part of the liquid outlet cavity 19, and the side walls of the two first shells 12a facing the second shell 13a block the two ends of the liquid outlet cavity 19. The lower part of the two side walls is provided with a notch 22, and the two notches 22 are connected with the guide channel 17 to connect the two liquid inlet cavities 18.

[0129] Specifically, the flow guide channel 17 is located at the lower part of the liquid outlet cavity 19, and the two are separated and arranged in an upper and lower layered form. Since the two liquid inlet current collectors 12 are attached to the two sides of the liquid outlet current collector 13, the two ends of the flow guide channel 17 are connected to the liquid inlet cavities 18 on both sides through the notches 22 on the two liquid inlet current collectors 12, and the two ends of the liquid outlet cavity 19 are sealed by the side walls of the two liquid inlet current collectors 12. Such a structural setting not only realizes the connection between the two liquid inlet current collectors 12, but also greatly saves the overall space, making the structure as compact as possible and reducing the space occupancy rate.

[0130] The present application also provides a battery 100, which is equipped with the heat exchange assembly 10 provided in the above embodiment. When the battery 100 is equipped with the heat exchange assembly 10 or heat exchange system in the present application, the battery 100 can also obtain effective heat exchange, which increases the stability and sustainability of the operation.

[0131] The present application also provides an electric device, which is equipped with the battery 100 provided in the above embodiment, thereby ensuring the reliability of the electric device.
