High-low temperature cycle chamber system analysis

The high-low temperature cycling test chamber can simulate the transient environment between high and low temperatures. In order to judge whether the production of Lu's reliability and stability and other parameters are qualified. It will provide you with a basis for predicting and improving the quality and reliability of your product. It is used to detect the resistance of products such as electronics, automobiles, rubber, plastics, aerospace and advanced communication equipment under repeated changes of heat and heat.

　　 First, high and low temperature cycle test box structure features:

Perfect styling upgrade, simple panel interface.

Day-Our imported color touch LCD Chinese/English microcomputer temperature controller.

Vertical three-box structure, automatic control of high and low temperature box circulation process, adjustable stay and conversion time, stainless steel liner, multi-format records, with multiple safety protection measures and devices.

Perfect protection alarm function: When there is short circuit, leakage, over temperature in the studio, compressor over pressure, overload, oil pressure, water cut and other abnormal conditions, the screen will automatically display the cause of the machine troubleshooting method, when the input voltage is not found When it is stable, it has an emergency stop device. The movement time of the cold and hot shock structures is within 10 seconds. Hot and cold shock temperature recovery time within 5 minutes, can meet the MTL, IEC, JIS, GJB and other specifications.

　　 Second, high and low temperature cycle test chamber structure:

1. Structure of the test chamber: The cold and heat shock chamber adopts the integral type structure. The test chamber consists of a high temperature test chamber at the top, a low temperature test chamber at the bottom, a refrigeration unit cabinet at the rear, and a rear panel at the left side. The electrical control cabinet (system) is composed of. In this way, the cabinet has a small footprint, a compact structure, and a beautiful appearance. The refrigeration unit is placed in an independent unit box to reduce the impact of vibration and noise of the refrigeration unit on the test box. At the same time, it is easy to install and maintain the unit. The control panel is placed on the left side of the chamber to facilitate operation.

2. Extracorporeal wall material: high-quality carbon steel plate with electrostatic color spray treatment on the surface.

3, box body wall material: imported SUS304 stainless steel, corrosion-resistant, easy to clean, beautiful and generous.

4, insulation materials: high-quality ultra-fine glass fiber cotton.

5, sample rack: stainless steel sample rack up and down the slide guide. Double force cylinders are used to provide smooth and even power. The positioning device of the sample rack is an indirect type electric sensor manufactured by FESTO of Germany.

6. Observation window: Open a 350×250mm electric-heated and moisture-proof temperature-separating observation window on the upper box (high temperature box).

7. Cable Threading Holes: Sliding cable threading tubes are installed on the upper part of the sample rack and the top of the high temperature test box body.

8, sample rack bearing: ≥ 30Kg.

9, high and low temperature cycling test chamber lighting device: moisture-proof lamp.

　　 Third, high and low temperature cycling test chamber air conditioning system :

1. Air control method: forced circulation ventilation and BTC. This method refers not only to the continuous operation of the cooling system, the control system according to the set temperature point through the PID automatic calculation output to control the output of the heater, and ultimately achieve a dynamic balance.

2. Air circulation device: Built-in air, recirculating air passage and stainless steel long-shaft ventilator, use efficient refrigerator and energy adjustment system, effective heat exchange through high-efficiency fan, achieve the purpose of temperature change. Adjustable air outlet adjustment through the air outlet greatly improves the temperature uniformity of the test chamber;

3, air cooling mode: multi-stage diaphragm air heat exchanger.

4, air heating method: high-quality nickel-chromium gold wire electric heater.
