AI Technical Summary
Existing methods for testing server rack heat dissipation cannot accurately reflect the true heat dissipation capacity of the heat dissipation device under different operating conditions, resulting in insufficient accuracy of the test results. This makes it difficult to reliably determine whether the heat dissipation device in the server rack meets the actual operating requirements, posing a safety hazard.
A cabinet heat dissipation testing device was designed, including components such as an air-catching ring, an air distribution duct, an air guide ring, a fixing ring, a diversion slit, a baffle, and a detector. The air-catching ring and narrow slit accelerate the hot airflow, and the diversion slit and baffle form an air spring to ensure consistent hot airflow pressure. The diversion duct is insulated, and the detector continuously monitors the temperature of the hot airflow, thus achieving accurate testing of heat dissipation capacity under different operating conditions.
This ensures the accuracy of the test data, reliably determines whether the heat dissipation effect of the heat dissipation device in the cabinet meets the actual needs, and reduces the safety risks of cabinet operation.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cabinet heat dissipation testing, and particularly relates to a cabinet heat dissipation testing device. BACKGROUND
[0002] As an independent or self-supporting cabinet for accommodating electrical or electronic devices, the cabinet is an indispensable core carrier of electrical control devices and is widely used in various electrical systems. When the electrical or electronic devices inside the cabinet are in a working state, heat will be continuously generated. If the heat cannot be dissipated in time, the temperature inside the cabinet will rise, which may affect the operation stability and service life of the devices. Therefore, a heat dissipation device is usually configured in the cabinet to regulate the heat, and the air cooling heat dissipation mode based on the built-in fan is a common heat dissipation form at present.
[0003] When the temperature inside the cabinet is abnormal, the electrical devices and the heat dissipation device inside the cabinet need to be detected. The existing air cooling heat dissipation usually installs a fan inside the electrical device, and the working efficiency of the built-in fan is different when the electrical device is in different working states. The heat dissipation effect of the built-in fan in different working efficiencies needs to be detected to prevent the built-in fan from being unable to effectively dissipate heat for the electrical device in a high-power working state. The existing detection method usually installs a temperature detector inside the cabinet for detection. However, since the working period of the electrical device is fluctuant, the change in the heat generation of the electrical device will directly cause the working efficiency of the built-in fan to continuously change, so that the temperature inside the cabinet is in a dynamic fluctuation state. The temperature detector is difficult to effectively and stably capture the key temperature parameters in the heat dissipation process, and cannot accurately reflect the real heat dissipation capacity of the heat dissipation device under different working conditions. Finally, the detection result precision is insufficient, and it is difficult to reliably judge whether the heat dissipation effect of the heat dissipation device in the cabinet meets the actual operation requirement of the cabinet, which brings potential risks to the safe operation of the cabinet.
[0004] Therefore, the present application provides a cabinet heat dissipation testing device to meet the needs. SUMMARY
