Abstract

The invention relates to a device with temperature and humidity control capability and an adaptive control method thereof. The device comprises a fan, a gas-liquid heat exchanger, a semiconductor refrigeration chip, a condenser, a temperature and humidity sensor, a control device and an external liquid supply system. The device can control the start and stop or the rotational speed of the fan according to the air temperature feedback inside the space, can automatically adjust the air side air flow during the heat exchange process and controls the air outlet temperature, thereby controlling thetemperature in the space; according to the humidity feedback in the space, the start and stop of the semiconductor refrigeration chip is controlled to control the humidity in the space at a constantlevel; and in particular, the device combines the gas-liquid heat exchanger and a semiconductor dehumidifier, and the semiconductor dehumidifier adopts a liquid cooling and heat dissipation mode to avoid the defects that the use and the refrigeration of the fan of a traditional dehumidifier are greatly influenced by the ambient temperature; and moreover, the overall condensation caused by the traditional low-temperature water-liquid-liquid heat exchanger is avoided, and the reliability of the device and the environmental adaptability in the conditions without low-temperature water and with thelimited space are greatly improved.

Description

technical field [0001] The invention relates to a heat dissipation device. Background technique [0002] Among the reliability influencing factors of various electronic equipment systems, the failures caused by the two factors of temperature and humidity account for the vast majority. Among them, the impact of temperature includes the impact caused by excessive temperature and temperature change, and the impact of humidity mainly includes problems such as voltage breakdown and moisture expansion. Therefore, for the high reliability design of electronic equipment, the stable control of temperature and humidity is particularly critical. Excessive temperature and humidity and fluctuating shocks cause damage and burnout of components. [0003] At present, for equipment in confined spaces, the main temperature and humidity control methods are as follows: [0004] The external circulation air-cooled environmental control system uses a special circulating ventilation device to p...

Problems solved by technology

This method solves the problem of using low-temperature water, but the independent dehumidifier increases the amount of equipment and reduces the reliability of the system; at the same time, the dehumidifier uses air-cooled heat dissipation, which is greatly affected by the ambient temperature and cannot be realized under high temperature conditions. Effective dehumidification, unable to meet the adaptive control of ambient temperature and humidity
