Hanging basket type two box cold and hot shock box

1Hanging basket type two box cold and hot shock boxProduct Features:

Kewen InstrumentHanging basket type two box cold and hot shock boxAdopting a brand new and precise exterior process design, the outer box is made of cold-rolled double-sided electrostatic resin high-temperature spray painted, and the inner box is all sealed and welded with SUS # 304 high-temperature resistant stainless steel. The insulation layer adopts fire-resistant high-strength PU polyurethane foam insulation material. Science and Technology Experimental EquipmentThe refrigeration system has introduced energy-saving refrigeration control technology from Japan and Germany, which saves more than 20% energy compared to traditional equipment. The control system and control circuit both use imported components.

IIProduct Usage:

The equipment is suitable for various types of electrical and electronic products, automotive parts LED、 Reliability testing of high and low temperature constants, various temperature shocks, and temperature changes for new energy, batteries, and other products, components, and materials.

IIIWorking Principle:

1. First, let's talk about the high-temperature heat storage tank: it uses high-power nickel chromium alloy heating wire for heating. The touch screen controller detects the real-time signal from the temperature sensing element, compares it with the set temperature signal, and obtains the comparison signal. The PID logic circuit of the instrument outputs the signal to control the on or off time ratio of the solid-state relay and adjust the output power of the heater to achieve automatic temperature control.

2. Secondly, the low-temperature storage tank: The temperature state inside the box is determined by the working status of the heater, evaporator, and fan in the air duct. The refrigerant flowing out through the expansion valve enters the evaporator inside the working chamber, absorbs heat inside the working chamber and vaporizes, causing the working chamber temperature to decrease; The vaporized working fluid is sucked in by the compressor and compressed into high-temperature and high-pressure gas, which is then condensed into liquid in the condenser. After passing through a screening program, it is throttled by an expansion valve in the laboratory equipment and re enters the evaporator in the working room to absorb heat and vaporize before being sucked in and compressed by the compressor. By working in a loop like this, the studio temperature is lowered to the set temperature requirement

3. Zui later said that the sample placement test slot: The instrument automatically controls the high and low temperature air valves, switches between low or high temperature storage rooms, and forms a closed-loop air circulation system with the high or low temperature slot to quickly reach the target temperature of the test.

The temperature status inside the sample placement test slot is determined by the working status of the heater, evaporator, and fan in the air duct. The sample placement testing chamber adopts a forced axial flow "dispersion" loop air working method, which can greatly improve the fluctuation, uniformity and other parameters of equipment operation.

The hanging basket type cold and hot shock chamber is composed of a high-temperature heat storage tank, a low-temperature cold storage tank, and a hanging (lifting) basket. As this equipment is a test chamber with high and low-temperature shock function assembled from two functional tanks, it is called a two box type cold and hot shock test chamber. Some people also refer to it as a two box high and low temperature impact test box or simply a cold and hot impact box. Commonly used for testing, experimentation or inspection in laboratories, research institutes, enterprises and institutions. The two box hanging basket type thermal shock box is commonly used in industrial industries such as electronics, electrical appliances, automotive parts, LED industry, finished or semi-finished products such as street lamps, touch screens, outdoor advertising screens, and communication industry.
