Description

Technical Field

[0001] The utility model relates to the technical field of high and low temperature test boxes, in particular to a high and low temperature test box with dustproof and heat dissipation functions. Background Art

[0002] At present, high and low temperature test chambers are widely used in electronics, electrical appliances, aviation, automobiles, scientific research and other fields to test the performance of products under various temperature environments. However, existing high and low temperature test chambers generally have poor dust and heat dissipation performance. During the test, dust easily accumulates inside the equipment, affecting the heat dissipation effect of the equipment, and then affecting the stability and service life of the equipment. Therefore, it is necessary to develop a high and low temperature test chamber with dust and heat dissipation functions. Utility Model Content

[0003] The utility model aims to provide a high and low temperature test box with dustproof and heat dissipation functions to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high and low temperature test box with dustproof and heat dissipation functions, comprising a test box body, a trapezoidal filter frame and an air inlet device, the front of the test box body is hingedly installed with a box door through a hinge, a controller is arranged on the outer side of the test box body, an air inlet device is arranged on the top of the test box body, a magnetic suction belt 2 is installed on the outer side of the air inlet device, a trapezoidal filter frame is installed on the top of the air inlet device, protective nets are arranged on both sides of the trapezoidal filter frame, dust-proof filter cotton is installed on both sides of the interior of the trapezoidal filter frame, and a magnetic suction belt 1 is installed on the bottom of the trapezoidal filter frame.

[0005] The test chamber body is an instrument for high and low temperature reliability tests. The opening and closing of the chamber door facilitates the staff to use the test chamber body. The staff can input the operating parameters of the test chamber body through the controller. When the test chamber body needs to dissipate heat, the air intake device is started. The air intake device is composed of three groups of axial flow fans. By powering on the air intake device, the airflow required for heat dissipation can be blown into the inside of the test chamber body to achieve heat dissipation. During the heat dissipation process, the protective net and dust filter cotton set on both sides of the trapezoidal filter frame can intercept dust in the air to prevent dust from entering the inside of the test chamber body. The electronic components inside the test chamber body can be protected and the service life of the equipment can be extended. Because the trapezoidal filter frame adopts a trapezoidal design, the air intake volume is increased while giving it a larger dust filtering area, which is less likely to be blocked, so that the device has better dust filtering and heat dissipation capabilities. The magnetic suction belt 1 can be magnetically attracted with the magnetic suction belt 2. The trapezoidal filter frame and the air intake device adopt a quick-release design, which is more convenient for the staff to clean and maintain the trapezoidal filter frame.

[0006] Preferably, the trapezoidal filter frame is magnetically installed by means of a first magnetic attraction belt and a second magnetic attraction belt.

[0007] Magnetic belt one can be magnetically attracted to magnetic belt two, and the trapezoidal filter frame and the air inlet device can be installed and disassembled through the magnetic attraction of magnetic belt one and magnetic belt two. The disassembly method through magnetic attraction is more convenient and quick, so that the staff can regularly clean and maintain the trapezoidal filter frame to ensure the dust filtering performance of the trapezoidal filter frame.

[0008] Preferably, an exhaust device is provided below the front of the test box body, and two sets of casters are installed on both sides of the bottom of the test box body by bolts.

[0009] The operation of the exhaust device can generate negative pressure inside the test chamber body, allowing air to circulate inside the test chamber body so that various components inside the test chamber body can be ventilated and dissipated. The staff can move the test chamber body through casters to move the test chamber body to a designated position for use by the staff.

[0010] Preferably, a handle is installed on one side of the front of the door, and a cat's eye is provided on the front of the door.

[0011] The handle can provide a gripping position for the staff's hands, making it convenient for the staff to hold the handle to open and close the box door. The cat's eye can facilitate the staff to peek into the inside of the device to check the status of the inspected object inside the device.

[0012] Preferably, a digital display screen is provided on the outside of the controller, and a button is provided on one side of the digital display screen.

[0013] The operating parameters of the controller can be displayed through the digital display screen, and the operating parameters of the controller can be input by the staff through the buttons. The operating parameters of the controller can be set by the staff through the coordinated use of the digital display screen and buttons. The controller adopts a PLC control system, which is a digital electronic device with a microprocessor and a digital logic control device used for automatic control.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. In the process of heat dissipation and dust prevention, the trapezoidal design of the utility model increases the air intake while providing a larger dust filtering area, making it less prone to clogging, and enabling the device to have better dust filtering and heat dissipation capabilities. The trapezoidal filter frame and the air inlet device adopt a quick-disassembly design, which makes it easier for staff to clean and maintain the trapezoidal filter frame.

[0016] 2. By energizing the air inlet device, the airflow required for heat dissipation can be blown into the test chamber body to achieve heat dissipation. During the heat dissipation process, the protective nets and dust filter cottons set on both sides of the trapezoidal filter frame can intercept dust in the air and prevent dust from entering the test chamber body. This can protect the electronic components inside the test chamber body and extend the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
