Description

[Technical Field]

[0001] This application claims priority from a Chinese application bearing application number 202422408755.7, filed with the China Patent Office on September 30, 2024, and incorporates all of the disclosures therein by reference.

[0002] The present application relates to the field of battery manufacturing technology, and more particularly to a heat exchanger-integrated air duct component and a battery inspection device. [Background technology]

[0003] The capacity-grading integrated machine is an important device in the lithium battery production process, and is mainly used in the battery formation process and capacity grading process. Because the capacity-grading integrated machine generates a large amount of heat during operation, all current capacity-grading integrated machines are equipped with a heat dissipation function design to ensure that the device is maintained in an appropriate operating temperature environment.

[0004] Current capacity grading integrated machines generally use a heat exchange air duct design, specifically, a heat exchanger and a fan are combined to form a heat exchange air duct inside the capacity grading integrated machine to achieve the purpose of heat dissipation.

[0005] However, in the current integrated capacity grading machine, the heat dissipation function modules based on the heat exchanger and the fan are installed on both sides of the housing of the integrated capacity grading machine, which makes the overall width of the integrated capacity grading machine excessively wide and inconvenient to transport.Furthermore, different types of integrated capacity grading machines require different heat dissipation function modules to form corresponding dedicated air ducts, which increases manufacturing costs. Summary of the Invention [Problem to be solved by the invention]

[0006] To solve the technical problem that the functional modules forming conventional air ducts have low versatility and are installed on both sides of the device, making the device excessively wide, the present application provides an air duct component with an integrated heat exchanger and a battery inspection device. [Means for solving the problem]

[0007] The present application provides an air duct component integrated with a heat exchanger, which includes a housing, a heat exchanger, and at least one fan module. A cavity is formed within the housing, and airflow passage openings communicating with the cavity are formed on both sides of the housing in the Y direction. The fan modules are installed on the bottom wall of the housing and are configured to eject gas within the cavity downward to create a negative pressure within the cavity. The heat exchangers are located on both sides of the housing in the Y direction, and at least a portion of each heat exchanger is installed within the cavity. Here, at least a portion of the orthogonal projection of the heat exchanger in the Y direction overlaps with the corresponding airflow passage opening, thereby cooling the gas that has entered the cavity through the airflow passage opening.

[0008] Illustratively, in some embodiments of the present application, a fan mounting rail extending along the X direction is provided on the bottom wall of the enclosure, and the fan module is configured to slide into the cavity along the fan mounting rail.

[0009] Illustratively, in some embodiments of the present application, the fan module includes a plurality of fans, and the plurality of fans are spaced apart along the X direction. The number of fan modules is plural, and the plurality of fan modules are spaced apart in the Y direction.

[0010] For example, in some embodiments of the present application, the fan module further includes a plurality of adapter boards, each of which is located on one side of each fan in the Y direction in a one-to-one correspondence, and has an electrical socket to which the fan is connected.

[0011] Illustratively, in some embodiments of the present application, a pull-out handle is provided at one end of the fan module in the X direction.

[0012] Illustratively, in some embodiments of the present application, the heat exchanger is configured to be removable along the X direction relative to the housing.

[0013] Illustratively, in some embodiments of the present application, the heat exchanger includes a pipe fitting that protrudes outward from the housing when the heat exchanger is mounted within the housing.

[0014] Illustratively, in some embodiments of the present application, the housing includes a plurality of lifting handles, the plurality of lifting handles being mounted on a top wall of the housing.

[0015] The present application also provides a battery testing device, which includes a housing, a pressure welding mechanism, and the above-mentioned heat exchanger-integrated air duct component. The heat exchanger-integrated air duct component and the pressure welding mechanism are installed in the housing, and the heat exchanger-integrated air duct component is located above the pressure welding mechanism in the Z direction. The heat exchanger-integrated air duct component can eject airflow toward the pressure welding mechanism to cool it.

[0016] Illustratively, in some embodiments of the present application, the battery testing device further includes a pipe that is installed on the top wall of the housing and located outside the housing, and that communicates with the heat exchangers on both sides in the Y direction. [Effects of the Invention]

[0017] To summarize the above, the heat exchanger-integrated air duct component and battery inspection device provided in the present application have at least the following technical effects.

[0018] The air duct component with integrated heat exchanger provided in the present application is installed in the housing of a battery testing device and is located above the crimping mechanism inside the housing of the battery testing device. In the air duct component with integrated heat exchanger, a fan module arranged on the bottom wall of the housing draws out the airflow inside the cavity and forms an airflow that sprays toward the crimping mechanism, thereby creating negative pressure inside the cavity, and the hot air outside the housing passes through the airflow passage opening and is cooled by the heat exchanger, i.e., the air inside the cavity becomes cold air, and therefore the air that sprays toward the crimping mechanism becomes cold air, thereby achieving the cooling purpose.

[0019] The heat exchanger-integrated air duct component provided in the present application is installed above the crimping mechanism, thereby forming a heat exchange circulating airflow within the housing that is used to cool the crimping mechanism. In this battery inspection device, during the battery inspection process, most of the heat generated by the crimping mechanism is discharged to the outside of the housing by the heat exchanger, thereby maintaining the crimping mechanism within an appropriate operating temperature range and ultimately ensuring the stability of the battery inspection device.

[0020] In addition, since the heat exchanger-integrated air duct component is located within the housing and above the pressure welding mechanism, the width of the battery testing device is reduced, making it easier to transport and reducing the installation area. As a result, the distance between the heat exchanger-integrated air duct component and the pressure welding mechanism is relatively short, which can provide a better cooling effect.

[0021] Furthermore, the heat exchanger-integrated air duct component is one of the constituent modules of this battery testing device, i.e., a modular layout design is used, which provides greater versatility and reduces the development costs of the device. [Brief explanation of the drawings]

[0025] The "X direction," "Y direction," and "Z direction" referred to in this application are determined based on a Cartesian coordinate system constructed based on the battery inspection device 1000 provided in this application. Here, the X direction is the longitudinal direction, i.e., the front-to-back direction, the Y direction is the lateral direction, i.e., the left-to-right direction, and the Z direction is the vertical direction, i.e., the up-down direction.

[0026] 1 is a schematic view of a battery testing device 1000 provided in one embodiment of the present application, viewed from one viewing angle. Referring to FIG. 1, the battery testing device 1000 includes a heat exchanger-integrated air duct component 100, a housing 400, and a crimping mechanism 500. The crimping mechanism 500 is a pin bed made up of pin terminals, and is used to electrically connect the entire battery to the corresponding pin terminals when the battery is crimped.

[0027] The heat exchanger-integrated air duct component 100 and the pressure welding mechanism 500 are installed in a housing 400, and the heat exchanger-integrated air duct component 100 is located above the pressure welding mechanism 500 in the Z direction.

[0028] The heat exchanger-integrated air duct component 100 can blow airflow toward the pressure welding mechanism 500 to cool the pressure welding mechanism 500 .

[0029] Figure 2 is a schematic view of the integrated heat exchanger and air duct component 100 of Figure 1 from one viewing angle. Figure 3 is a schematic view of the integrated heat exchanger and air duct component 100 of Figure 2 from another viewing angle. Figure 4 is a schematic view of the integrated heat exchanger and air duct component 100 of Figure 2 from another viewing angle.

[0030] 2 to 4, this heat exchanger-integrated air duct component 100 includes a housing 10, a heat exchanger 30, and at least one fan module 20. A cavity R is formed within the housing 10, and airflow passage openings C that communicate with the cavity R are formed on both sides of the housing 10 in the Y direction.

[0031] The fan module 20 is installed on the bottom wall of the housing 10 and configured to blow gas in the cavity R downward to create negative pressure in the cavity R. The heat exchangers 30 are located on both sides of the housing 10 in the Y direction and are at least partially installed within the cavity R.

[0032] At least a part of the orthogonal projection of the heat exchanger 30 in the Y direction overlaps with the corresponding airflow passage opening C so as to cool the gas entering the cavity R through the airflow passage opening C.

[0033] In this embodiment, a cavity R is formed in the housing 10, and airflow passage openings C are opened on both sides of the housing 10 in the Y direction. A fan module 20 and a heat exchanger 30 are disposed in the cavity R, and the fan module 20 can form an airflow, which causes the gas in the cavity R to be ejected downward, i.e., toward the pressure welding mechanism 500.

[0034] The heat exchanger 30 has a heat exchange function and is installed at the position of the airflow passage opening C. A portion of the heat exchanger 30 is exposed by the airflow passage opening C, so that the gas needs to exchange heat through the heat exchanger 30 before entering the cavity R through the airflow passage opening C. Note that the heat exchange function components of the heat exchanger 30 are exposed by the airflow passage opening C, meaning that all the gas entering the cavity R needs to pass through the heat exchange function components of the heat exchanger 30, and the heat exchanger 30 here is mainly intended for cooling.

[0035] As can be understood, since the fan module 20 draws out the gas in the cavity R, a negative pressure can be formed in the cavity R, where the negative pressure refers to the air pressure in the cavity R being lower than the air pressure outside the housing 10, that is, the air pressure in the cavity R being lower than the air pressure inside the housing 400. As can be understood, the gas on the high pressure side flows to the low pressure side, that is, the gas inside the housing 400 enters the cavity R after passing through the airflow passage opening C and the heat exchanger 30, so that the gas in the cavity R becomes cold air, and of course, the cold air here is relative to the gas outside the housing 10, that is, the gas temperature inside the cavity R is lower than the gas temperature outside the housing 10.

[0036] The fan module 20 blows the cool air in the cavity R downwards towards the pressure mechanism 500, thereby cooling the pressure mechanism 500 and reducing the risk of the pressure lowering / lowering mechanism 500 overheating during operation.

[0037] To better understand this solution, we will explain it with reference to Fig. 1. After the cool air blown downward from the heat exchanger-integrated air duct component 100 exchanges heat with the pressure welding mechanism 500, the temperature of the air increases and the air diffuses to the surroundings, i.e., the hot air is mainly distributed around the pressure welding mechanism 500.

[0038] As a result, the surrounding hot air flows upward, creating a negative pressure in the cavity R. This hot air is cooled by the corresponding heat exchangers 30 through the air flow passage openings C on both sides of the housing 10 in the Y direction, enters the cavity R, and is then ejected by the fan module 20 toward the pressure welding mechanism 500.

[0039] In this way, by installing the heat exchanger-integrated air duct component 100 provided in the present application above the crimping mechanism 500, a heat exchange circulating airflow (indicated by the arrows in Figure 1) used to cool the crimping mechanism 500 can be formed within the housing 400, and in the battery inspection device 1000, most of the heat generated by the crimping mechanism 500 during the battery inspection process is discharged to the outside of the housing 400 by the heat exchanger 30, ensuring as much as possible that the crimping mechanism 500 is maintained within an appropriate operating temperature range, thereby ensuring the stability of the battery inspection device 1000.

[0040] In addition, since the heat exchanger-integrated air duct component 100 is located within the housing 400 and above the pressure welding mechanism 500, the width of the battery testing device 1000 is reduced, making it easier to transport and reducing the installation area. As a result, the distance between the heat exchanger-integrated air duct component 100 and the pressure welding mechanism 500 is relatively short, providing a better cooling effect.

[0041] Furthermore, the heat exchanger-integrated air duct component 100 is one of the constituent modules of the battery inspection device 1000, i.e., a modular layout design is used, which provides greater versatility and reduces the development costs of the device.

[0042] Note that the battery inspection device 1000 here may refer to an integrated capacity grading machine, which is used to inspect batteries in battery trays 700, and the pressure-welding mechanism 500 is equipped with a power supply module for battery inspection. During the process of inspecting batteries in battery trays 700 using the pressure-welding mechanism 500, the temperatures of the power supply module in the pressure-welding mechanism 500 and the batteries in the battery trays 700 rise, so the heat dissipation here is mainly aimed at the heat generated during the inspection process.

[0043] Furthermore, in the embodiment shown in Figures 2 and 3, the two heat exchangers 30 are arranged corresponding to the positions of the air flow passage openings C on both sides in the Y direction, but of course, the number of heat exchangers 30 is not limited to the illustrated embodiment and may be an even number such as four or six, i.e., the heat exchangers 30 may be arranged symmetrically.

[0044] Furthermore, the illustrated housing 10 is a rectangular housing, i.e., a six-sided box structure is used, but of course the shape of the housing 10 is not limited to the illustrated embodiment and other multi-sided box structures or cylindrical structures may be used. Also, although the illustrated airflow passage opening C is a rectangular opening, of course it is not limited to this and may have any shape as long as it can ensure that the heat exchange functional components of the heat exchanger 30 are sufficiently exposed.

[0045] Illustratively, in some embodiments, the battery testing apparatus 1000 further includes a pipe 600, which is installed on the top wall of the housing 400 and located outside the housing 400, and which is connected to the heat exchangers 30 on both sides in the Y direction.

[0046] In this embodiment, the pipes 600 are used to circulate the heat exchange medium, and the temperature of these heat exchange media is lower than the temperature of the gas inside the housing 400. As the heat exchange media circulates inside the heat exchanger 30, they absorb the heat of the gas passing through the heat exchanger 30 and expel that heat outside the housing 400.

[0047] The heat exchange medium may be a fluid medium such as water, oil, or refrigerant, and in a specific application, water is used as the heat exchange medium, i.e., the heat exchanger 30 is an aqueous heat exchanger. The heat exchanger 30 may be a tubular heat exchanger, a plate heat exchanger, or the like, and the heat exchange functional parts of the heat exchanger 30 are correspondingly heat exchange capillaries in a tubular heat exchanger and metal laminate plates in a plate heat exchanger.

[0048] Referring to FIG. 2, in some embodiments, a fan mounting rail 11 extending along the X direction is provided on the bottom wall of the housing 10, and the fan module 20 is configured to slide into the cavity R along the fan mounting rail 11.

[0049] In this embodiment, a fan mounting rail 11 is attached to the bottom wall of the housing 10, and the fan mounting rail 11 is used to guide the fan module 20 so that it slides into the cavity R from the X direction.

[0050] A fan mounting opening H1 is formed on one side of the housing 10 in the X direction so as not to interfere with the installation of the fan module 20. The fan mounting opening H1 is located at the position of the fan mounting rail 11, and the fan module 20 can pass through the fan mounting opening H1 and slide into the cavity R along the fan mounting rail 11.

[0051] By configuring the fan module 20 so that it can be pulled out along the X direction, not only is installation easy, but subsequent maintenance is also simplified.

[0052] In a specific application, the fan module 20 further includes a fan mounting base plate 24, and the fan mounting rails 11 are guide stands installed on both sides of the fan mounting opening H1 in the Y direction and extending along the X direction. The guide stands on both sides have guide slots that fit into the fan mounting base plate 24 to guide the fan module 20 when inserted into the cavity R along the X direction.

[0053] In addition, an X-side cover plate (not shown) is installed on one side of the fan module 20 in the X direction. When the fan module 20 is inserted into the cavity R, the X-side cover plate covers the fan mounting opening H1 and is fixed together with the housing 10 by fitting to the screw joints, thereby locking the fan module 20.

[0054] 2 and 4, a pull-out handle 22 is provided at one end of the fan module 20 in the X direction.

[0055] In this embodiment, the fan module 20 further includes a pull-out handle 22 located at one end in the X direction. When the fan module 20 is attached to the housing 10, the pull-out handle 22 is located outside the housing 10, making it easy for an operator to insert or pull out the fan module 20 into or from the housing 10 along the X direction using the pull-out handle 22.

[0056] Illustratively, in some embodiments, the fan module 20 includes a plurality of fans 21, and the plurality of fans 21 are spaced apart along the X direction. The number of fan modules 20 is plural, and the plurality of fan modules 20 are spaced apart in the Y direction.

[0057] In this embodiment, the multiple fan modules 20 are arranged in the housing 10 at intervals in the Y direction, and each fan module 20 includes multiple fans 21 spaced apart along the X direction, thereby arranging the multiple fans 21 in a rectangular array.

[0058] Here, the purpose of installing multiple fans 21 is mainly to ensure that sufficient cool air flow is generated, that the heat dissipation efficiency for the pressure welding mechanism 500 is sufficient, and that the pressure welding mechanism 500 is always maintained within an appropriate temperature range during operation.

[0059] As can be understood, when the number of fan modules 20 is plural, the number of fan mounting rails 11 and fan mounting openings H1 is plural and equal to the number of fan modules 20. In the embodiment shown in Figure 2, the number of fan modules 20 is three, but of course the number of fan modules 20 may be adjusted according to heat dissipation needs.

[0060] As can be understood, the number of fan modules 20 can be adjusted according to the required heat dissipation efficiency, and the number of fan modules 20 can be minimized to reduce costs while still meeting the heat dissipation demand.

[0061] For example, in some embodiments, the fan module 20 further includes a plurality of adapter boards 23, each of which is located on one side of each fan 21 in the Y direction in a one-to-one correspondence, and has an electrical socket to which the fan 21 is connected.

[0062] In this embodiment, each fan 21 corresponds to one adapter board 23, and the adapter board 23 is located on one side of the corresponding fan 21 in the Y direction, and an electrical socket is installed on the adapter board 23, which is connected to the fan 21 to supply power.

[0063] This arrangement allows the electrical plug of each fan 21 to be connected to a corresponding nearby electrical socket, shortening the length of the electrical wiring of the electrical plug and reducing the risk of interference due to excessively long electrical wiring, simplifying the complexity of the internal wiring of the fan module 20, and facilitating installation and removal of the fans 21.

[0064] In a specific application, each fan 21 and each adapter board 23 are fixedly mounted on a corresponding fan mounting base plate 24 .

[0065] Illustratively, in some embodiments, the heat exchanger 30 is configured to be removable along the 10X direction relative to the housing.

[0066] In this embodiment, to ensure that the heat exchanger 30 can be pulled out along the X direction, a heat exchanger mounting opening H2 is provided on one side of the housing 10 in the X direction, and the heat exchanger mounting opening H2 is configured to allow the heat exchanger 30 to pass through and be inserted into the housing 10 along the X direction.

[0067] By configuring the heat exchanger 30 so that it can be pulled out along the X direction, not only is it easy to install the heat exchanger 30, but subsequent maintenance is also simplified.

[0068] In a specific application, the heat exchanger mounting opening H2 and the fan mounting opening H1 are located on the same side, and a heat exchanger cover plate (not shown) is installed at one end of the heat exchanger 30 in the X direction. When the heat exchanger 30 is inserted into the cavity R, the heat exchanger cover plate abuts against the side wall of the housing 10 in the X direction, covering the heat exchanger mounting opening H2 and fitting to the screw fittings, thereby securing the heat exchanger 30 to the housing 10.

[0069] Illustratively, in some embodiments, heat exchanger 30 includes a pipe fitting 31 that protrudes outward from housing 10 when heat exchanger 30 is mounted within housing 10 .

[0070] In this embodiment, the heat exchanger 30 further includes a pipe joint 31 that is adapted to fit the pipe 600 to allow the heat exchange medium flowing through the pipe to be introduced into the heat exchanger 30 .

[0071] In the illustrated embodiment, each heat exchanger 30 has two corresponding pipe joints 31, one of which is an inlet pipe and the other is an outlet pipe. Correspondingly, the number of pipes 600 is also two, one of which is an inlet pipe and the other is an outlet pipe, and thus can be adapted to the heat exchanger 30 to form a circulating heat exchange medium circuit.

[0072] Illustratively, in some embodiments, the housing 10 includes a plurality of lifting handles 12 , which are mounted on the top wall of the housing 10 .

[0073] In this embodiment, a plurality of lifting handles 12 are further fixedly attached to the top wall of the housing 10, which makes it convenient for workers to carry and install the housing 10. In the illustrated embodiment, there are four lifting handles 12, and each lifting handle 12 is located near one of the four corners of the housing 10, but the number of lifting handles 12 can be adjusted as needed.

[0074] Although the embodiments of the present application have been shown and described above, these embodiments are merely illustrative and should not be construed as limiting the present application, and those skilled in the art may make changes, modifications, substitutions, and variations to these embodiments within the scope of the present application.
