Automatic regulation type constant temperature box

Abstract

The present invention relates to an automatic regulated thermostat. It includes a tank body, a fan mounted on the top of said tank body and a bearing plate mounted in the interior of said tank body. The control circuit of said thermostat includes a power supply portion, a temperature regulation control component and a heating component placed in the interior of said tank body, the temperature regulation control component includes a T-type temperature-sensing thermowire, a temperature controller, a double-control relay and several single-control relays.

Description

【Technical field】 [0001] The invention relates to a constant temperature box, in particular to an automatic adjustment type constant temperature box used for heat performance testing of various electronic products such as computers. 【Background technique】 [0002] Computers and other electronic products have an important performance index: thermal performance index, which reflects the working status and operation of electronic products under different ambient temperatures. When testing this indicator for electronic products, a simulated temperature environment is required, and the product is tested in the simulated temperature environment. [0003] Usually, the practice in the industry is to design an incubator, and put the product to be tested into the incubator. The temperature inside the incubator can be adjusted within the range required by the test parameters and maintained at the required temperature. In this way, the incubator is equivalent to simulating the environ...

AI Technical Summary

Problems solved by technology

The heating device is composed of a light bulb or a heating tube. These two heat sources are mainly radiant heat. Only the part that can shine on the light can receive heat, and the part that cannot shine can not receive heat, which will cause the product under test in the test area to be heated. uneven

And it needs to rely on the heat conduction groove to force the heat in the box to convect. However, the convection that the heat conduction tube can form is limited, and the temperature in the incubator cannot be quickly balanced.

And if the bulb is used to generate heat, its service life is short

[0005] In fact, the computers and other products we design are used in a natural convection environment, and the temperature of each part of the product is basically the same. If the thermostat cannot simulate the actual use, the meaning of testing and design verification will be lost
