[0002] The automatic detection equipment applied to battery formation and detection is usually divided into two major parts: a power supply part and a mechanical part. The power supply part is used to control the voltage, current detection and constant current output of the battery, and the mechanical part is used to control the fixture to clamp the battery and lead the wire to the power supply part. The battery uses a tray as a clamping carrier. One device may place 1 to 10 trays, and each tray corresponds to one layer of the mechanical part. During the operation of the device, a large amount of heat will be generated at the contact parts between the probe and the battery and the wire. The battery itself will also generate huge heat. Hot air rises and cold air descends. The air temperature near the roof in the battery room is higher than that near the bottom surface. Therefore, the temperature of the trays and batteries in the uppermost layer of the mechanical part is higher than that of the trays and batteries in the lowermost layer of the mechanical part.

[0003] Therefore, it is necessary to provide a new design of a battery heat dissipation structure with centralized air intake through a cold air groove to solve the above technical problems. Summary of the Utility Model

Each detection mechanism includes a horizontally arranged battery tray, a plurality of batteries to be detected arranged in a vertical array in the battery tray, and a probe board and a probe arranged directly above the battery tray through a lifting mechanism.

[0007] A cold air blower is arranged at the top of the detection cabinet. Cold air grooves are symmetrically arranged vertically on both sides of the detection cabinet. The cold air blower outputs cold air to the cold air grooves on both sides respectively. A wind collecting cover is arranged on the top surface of the probe board in each detection mechanism. Both sides of each layer of the wind collecting cover are communicated with the cold air grooves on both sides. A plurality of heat dissipation blowers are arranged in an array on the bottom wall of each wind collecting cover.

[0008] Further, the cold air groove is a tubular structure. A plurality of air outlets are arranged at equal intervals on the side of the cold air groove close to the detection mechanism. The air outlets are respectively communicated with the wind collecting cover.

[0010] Further, the cooling fan is an adjustable-speed fan, and the air flow direction is from top to bottom.

[0022] As Figure 1-2 shown, a battery heat dissipation structure with centralized air intake through a cold air duct includes a detection cabinet 9, and a number of detection mechanisms arranged in layers in the detection cabinet 9 along the vertical direction. Each of the detection mechanisms includes a horizontally arranged battery tray 6, a number of batteries 5 to be detected arranged in the battery tray 6 in an array along the vertical direction, and a probe board 7 and probes 8 arranged directly above the battery tray 1 through a lifting mechanism;

[0023] A cold air blower 1 is provided at the top of the detection cabinet 9, and cold air ducts 2 are symmetrically arranged vertically on both sides of the detection cabinet 9. The cold air blower 1 outputs cold air to the cold air ducts 2 on both sides respectively. A wind collecting cover 4 is provided on the top surface of the probe board 7 in each of the detection mechanisms. Both sides of each layer of the wind collecting cover 4 are communicated with the cold air ducts 2 on both sides, and a number of heat dissipation blowers 3 are arranged in an array on the bottom wall of each of the wind collecting covers 4.

[0024] It is worth mentioning that exhaust holes are provided on the probe board 7, and the exhaust holes are communicated with the wind collecting cover 4 to transmit cold air from top to bottom.

[0025] Specifically, as shown in the figure, the cold air slot 2 is a tubular structure, and a plurality of air outlets are evenly spaced apart on one side of the cold air slot close to the detection mechanism, and the air outlets are respectively connected to the air collecting hood 4 .

[0026] Specifically, as shown in the figure, connecting slots are reserved on both sides of the air collecting cover, and the connecting slots are fixedly connected with the air outlet by screws.

[0027] Specifically, as shown in the figure, the heat dissipation fan 3 is an adjustable speed fan, and the wind direction is from top to bottom. The wind speed can be adjusted according to the temperature of the mechanical part, and the air intake volume can be changed to make the battery temperature consistent.

[0028] Specifically, the specific implementation principle of the utility model is:

[0029] The working principle of the utility model mainly relies on the synergy of the cold air circulation system and the heat dissipation fan. The specific steps are as follows:

[0030] Cold air supply: After the air cooler 1 is started, it continuously outputs cold air to the cold air slots 2 on both sides of the detection cabinet 9. The cold air slots 2 serve as transmission channels for cold air, and the cold air flowing inside them is guided to the air collecting hoods 4 of each detection mechanism through evenly arranged air outlets.

[0031] Cold air distribution: An air collecting hood 4 is arranged above the probe plate 7 of each detection mechanism, and connecting slots are reserved on both sides of the air collecting hood 4. These slots are fixedly connected with the air outlet of the cold air slot 2 by screws to ensure that the cold air can smoothly enter the interior of the air collecting hood 4.

[0032] Cold air blows downward: A plurality of speed-adjustable heat dissipation fans 3 are arranged in an array on the bottom wall of the air collecting hood 4. When the cold air enters the air collecting hood 4, the heat dissipation fans 3 are started to blow the cold air out from the bottom of the air collecting hood 4, forming a cold air flow from top to bottom.

[0033] Heat dissipation effect: The cold air is blown directly to the battery 5 to be tested in the battery tray 6, and the heat generated by the battery is removed through heat exchange, so as to achieve rapid cooling of the battery. Since the heat dissipation fan 3 is an adjustable speed fan, the wind speed can be adjusted according to the actual temperature of the battery to achieve the best heat dissipation effect.

[0034] Circulation heat dissipation: After taking away the heat from the battery, the cold air is discharged to the outside of the cabinet through the ventilation system of the detection cabinet 9 or natural convection, forming a complete cold air cycle. At the same time, the air cooler 1 continuously supplies new cold air to the cold air slot 2 to ensure the continuous heat dissipation process.

[0035] With the provision of the air cooler 1 and the air collecting hood 4, the air sent by the air cooler is gathered in the cold air tank 2 and then secondarily sent by the battery cooling fan 3 in the air collecting hood 4, so that the air above the battery 5 enters evenly, ensuring that the temperature of each battery 5 is uniform after heat dissipation, improving the test accuracy and reliability of the equipment, and prolonging the system life.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
