Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically an icing test chamber for airborne equipment. Background Technology

[0002] Test chambers are a general term for products in the environmental testing industry. They simulate natural climate environments within an effective space. Types of tests include: high and low temperature test chambers, xenon lamp aging test chambers, ultraviolet aging test chambers, box-type rain test chambers, rust-preventive greases, drip devices, cleanroom storage cabinets, nitrogen storage cabinets, and non-standard products.

[0003] When using current test chambers, it is necessary to conduct ice-applying tests on airborne equipment. Traditionally, the test is conducted by keeping the entire interior of the chamber at a low temperature, which cannot achieve the desired ice-applying effect and makes it unsuitable for ice-applying testing. Furthermore, the ice structure on one side of the bottom is applied to the bottom of the equipment, which cannot provide complete coverage and thus reduces the efficiency of the test. Utility Model Content

[0004] The purpose of this utility model is to provide an icing test chamber for airborne equipment, in order to solve the problem mentioned in the background art that, when using current test chambers, it is necessary to conduct icing tests on airborne equipment. Traditionally, the test is conducted by keeping the entire interior of the chamber at a low temperature, which cannot achieve the desired icing effect and makes it unsuitable for icing tests. Furthermore, the ice structure on only one side of the bottom of the equipment cannot be fully covered, thus failing to improve the efficiency of the test.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An airborne equipment icing test chamber includes a main chamber, with bottom pads symmetrically joined to the bottom surface of the main chamber. A control panel is fixedly snapped onto one side of the main chamber. A sealing door panel is hinged to the open side of the main chamber, and an observation window is fixedly provided on the side of the sealing door panel. An adjusting cylinder is vertically fixedly connected to the top surface of the main chamber. A sealing groove is formed on the open side of the main chamber. An inner insulation layer is fixedly provided on the inner side of the main chamber. A movable top box is horizontally arranged on the inner side of the inner insulation layer. A blocking door panel is horizontally snapped onto one side of the movable top box. A bottom groove is horizontally formed on the inner bottom surface of the main chamber. Ice packs are placed inside the bottom channel and the movable top box. A fixed inner box is horizontally fixed to the inner side of the main box. A circulation pump, an evaporator, and a compressor are fixed to the inner side of the fixed inner box. A refrigeration pipe is vertically inserted into the top surface of the fixed inner box. A control main board is fixedly snapped into the inner wall of the main box. Bottom screw holes are symmetrically opened on the bottom surface of the main box. A connecting screw is fixedly inserted into the top surface of the bottom pad. A storage tank is fixed to the inner side of the fixed inner box. A sealing frame is fixed to one side of the sealing door panel.

[0007] In a preferred embodiment of this utility model: one side of the main housing is open, there are four bottom pads, and the tops of the four bottom pads are all connected to the bottom opening of the bottom screw hole, and the control panel and the control motherboard are electrically connected to each other.

[0008] In a preferred embodiment of this utility model: the sealing door panel is fastened to the side opening of the main body, the adjusting cylinder is vertically fixedly connected to the center of the top surface of the main body, and the output end extends vertically downward to the interior of the main body, the bottom end of the extension is fixedly connected to the center of the top surface of the movable top box, and the sealing groove is opened near the edge of the opening of the main body.

[0009] In a preferred embodiment of this utility model: the bottom surface of the movable top box is open, and the movable top box and the bottom channel are arranged in parallel and superimposed on each other. The blocking door is horizontally snapped into the side opening of the movable top box, and the bottom channel is horizontally opened at the center of the inner bottom surface of the main body.

[0010] As a preferred embodiment of this utility model: the fixed inner box is fixedly installed on the inner side of the main body near the bottom surface. The circulating pump, evaporator and compressor are all connected to each other through pipes. The two ends of the refrigeration pipe are connected to the circulating pump and the compressor, and the refrigeration pipe is vertically embedded in the inner wall of the inner insulation layer.

[0011] In a preferred embodiment of this utility model: the bottom screw holes are symmetrically opened on the bottom surface of the main box near the four corners, the top of the connecting screw is fixedly connected to the inner side of the bottom screw hole, the storage tank is connected to the circulating pump through the pipeline, and one side of the sealing frame is correspondingly snapped into the inner side of the sealing channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the configuration of the side control panel, enables the main board to control the compressor, circulating pump 14, and evaporator in coordination. This process compresses and transports the refrigerant inside the storage tank into the refrigeration pipes, creating a specified low-temperature environment inside the main housing. The inner insulation layer maintains this sustained low temperature. Ice packs are placed in the bottom channel and the movable top box; the sustained low temperature inside the main housing causes the ice packs to freeze. When onboard equipment needs to be inspected, the equipment can be placed on the top surface of the main housing, with the bottom surface in contact with the equipment. The top surface of the ice pack at the bottom, after the sealing door is closed, allows the sealing frame to be snapped into the sealing channel for further sealing. Then, the output end of the top adjusting cylinder is controlled to extend downward, causing the output end to squeeze the movable top box downward, so that the bottom surface of the internal ice pack is placed against the top surface of the equipment and stops, forming an upper and lower clamping ice application operation. The internal equipment operation can be observed through the observation window, forming an ice application test operation for the equipment. The integrated structure makes it more convenient and intelligent to use, and the adjustable upper and lower clamping ice application structure makes the testing and treatment of the equipment more comprehensive and efficient.
