Description

Technical Field

[0002] 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 the maximum number of batteries loaded on each tray can reach 256. 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, and the battery itself will also generate a huge amount of heat. Due to the closed or semi-closed environment of the tray, untimely heat dissipation will cause changes in the charge and discharge performance of the battery, resulting in inaccurate testing, accelerating the aging of the device, and reducing the reliability of the device. Figure 1 The traditional battery heat dissipation structure is shown. The fan 100 is arranged on the upper slide plate 102, above the tray 101, and the wind blows from top to bottom. Since the heat dissipation fan blows directly from top to bottom, the air volume and flow rate received by each battery are not balanced, resulting in uneven heat dissipation.

A number of heat dissipation fans are symmetrically arranged on the left and right sides of the air collecting hood.

[0024] As Figures 2-4 shown, a battery detection and heat dissipation air duct structure includes a detection machine base 8 and a battery tray 1 provided on the detection machine base 8. The battery tray 1 is a semi-closed structure with an upward opening, and a plurality of batteries 2 to be detected are arranged in the battery tray 1 in a vertical array.

[0025] It further includes a probe board 4 provided directly above the battery tray 1 through a lifting mechanism. Probes 3 for connecting to the electrode plates of the batteries 2 are arranged in an array on the bottom surface of the probe board 4.

[0026] A wind collecting hood 6 is fixedly connected to the top surface of the probe board 4. A plurality of heat dissipation fans 5 are symmetrically arranged on the left and right sides of the wind collecting hood. An exhaust hole is provided on the bottom wall of the battery tray 1 located between the gaps of two adjacent batteries 2. A corresponding upper exhaust hole 7 is provided on the probe board 4 at the position corresponding to each lower exhaust hole. The upper exhaust hole 7 is communicated with the wind collecting hood 6, and a heat dissipation air duct is formed among the upper exhaust hole 7, the lower exhaust hole and the wind collecting hood 6.

[0027] This structure enables air to enter from both sides at the top of the wind collecting hood, concentrate in the cavity of the wind collecting hood, form a flow direction from top to bottom for the exhaust holes, construct a positive pressure environment, and the heat generated by each part during the operation of the battery can be quickly taken away.

[0028] Specifically, as shown in the figure, the wind collecting hood 6 is a square structure body with a hollow air duct space. Fixed frames are symmetrically arranged on both sides of the wind collecting hood 6, and the heat dissipation fans 5 are installed on the fixed frames.

[0029] Specifically, as shown in the figure, the heat dissipation fan is an adjustable speed fan, and the blowing direction of the heat dissipation fan 5 is from outside to inside.

[0030] Specifically, as shown in the figure, the lower side of the wind collecting hood 6 and the top surface of the probe board 4 are fixed and sealed by screws.

[0031] Specifically, as shown in the figure, the upper exhaust hole 7 and the lower exhaust hole are directly corresponding up and down.

[0032] Specifically, the specific implementation principle of the present utility model is as follows:

[0033] The working principle of the present utility model mainly depends on an efficient air flow and heat conduction mechanism. When the battery 2 to be detected is placed in the battery tray 1 and the probe board 4 is lowered to a suitable position through the lifting mechanism so that the probe 3 is connected to the electrode plate of the battery 2 for detection, the system starts to work.

[0034] Start of the heat dissipation fan: At this time, the adjustable speed heat dissipation fans 5 installed on both sides of the wind collecting hood 6 start to work and blow from outside to inside at the set wind speed. These fans form a strong air flow inside the wind collecting hood 6 through their strong suction or thrust.

[0035] Air flow path: As the heat dissipation fans operate, the external cold air is sucked into the wind collecting hood 6 and passes through the hollow air duct space inside the wind collecting hood 6. Subsequently, this cold air enters the battery tray 1 through the upper exhaust hole 7, especially between the gaps of two adjacent batteries 2.

[0036] Heat Exchange and Exhaust: Cold air exchanges heat with the heated battery 2 inside the battery tray 1, absorbing the heat generated by the battery. The heated air is exhausted through the lower exhaust holes on the bottom wall of the battery tray 1, forming a circulating heat dissipation air duct.

[0037] Adjustable Speed Function: Since the cooling fan is adjustable in speed, the wind speed can be flexibly adjusted according to the actual heat generation during the battery detection process to achieve the best heat dissipation effect.

[0038] With the settings of the air collecting hood and the cooling fan in this utility model, the incoming air is first concentrated in the air collecting hood, and the positive pressure environment guides the air out of the exhaust holes until it reaches the battery and the tray, enabling the heat generated by each part during the battery operation to be quickly taken away. Moreover, the cooling fan is an adjustable speed fan, which can adjust the wind speed as required according to the battery temperature, change the air intake volume, resulting in a better heat dissipation effect for the battery and its working environment, reducing the temperature rise of the battery during operation, minimizing the difference in battery temperature, ensuring the consistency of battery temperature, improving the test accuracy and reliability of the equipment, and extending the service life of the equipment.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.

[0040] In addition, it should be understood that although this specification is described according to 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.
