Solution to the uneven temperature control of small high and low temperature cycle test device

Wuxi Guanya small high and low temperature cycle test device uses refrigerant as the medium to transfer the heat generated by other equipment or equipment that needs to be cooled, and dissipates the heat to the outside of the equipment through the refrigeration system, so as to ensure that the equipment works within the normal temperature range.

.

Widely used a variety of experimental equipment
.


Before use, it is necessary to open the outer package and check whether the accessories are complete according to the packing list.
After unpacking, lift the small high-low temperature cycle test device from the wooden packaging base and lay it flat in a spacious position to check whether the whole body of the device is transported.
If it is damaged during transmission, push it to the installation position after confirming that it is correct, put the device in a stable state, and then connect the external circulation outlet and return pipes of the device

1.
The structure of the equipment greatly affects the temperature uniformity during operation.
Because the structure is difficult to be completely symmetrical, it will adversely affect the temperature uniformity
.

Top supply air and bottom return air
.

Obviously, this structure has good left-right symmetry, and it is easier to achieve uniform temperature on the left and right sides, but the structure is asymmetrical from top to bottom and completely different from front to back, which has an uneven effect on the temperature of the working space
.

　　2.
Due to the heat conduction of the box wall, heat loss such as heat leakage (high temperature box) or cold leakage (low temperature box) occurs.
In order to compensate for the heat loss, there must be a temperature difference in the supply air.
The supply air temperature of the high temperature box is higher than the working temperature in the box.
, the supply air temperature of the low temperature box is lower than the working temperature in the box
.

　　3.
Due to the unequal heat transfer coefficient of the box wall, some have local heat transfer such as threading holes.
The temperature of the box wall is not uniform, so that the radiation convection heat transfer of the box wall is not uniform, which affects the uniformity of the temperature field
.

　　4.
The sealing of the box is not good, such as air leakage, which affects the uniform temperature field during work
.

5.
When the volume of the items in the box is too large, or the way or position of placement is inappropriate, the air convection is blocked.
A large temperature deviation will occur
