Abstract

The utility model relates to a minitype high-efficiency self-adapting anti-rust dehumidifier used for ambient humidity control in a small space like machine cases, machine cabinets, etc. The utility model is characterized in that a cooling end of a cooling device contacts a condenser closely, a hot end of the cooling device contacts a radiator closely, and a heat-insulating layer seals the circumference of the cooling device. An air inlet is arranged on the machine case corresponding to the condenser, the surface of which is coated with a drainage coating, and an air outlet is arranged on the machine case corresponding to an exhaustion fan. By a designed bent air duct, cold air educed from a semiconductor cold end is used as cooling gas of a heat making end, and thus dehumidification efficiency and adaptability of high temperature environment of the cooling device are improved. An ultra-thin drainage layer is formed on the surface of the cooling end and enables condensed water to form an orbicular shape so as to flow into a seeper vessel quickly, and a new surface with low temperature can show up, so coagulation efficiency of low power equipment can be improved. The minitype high-efficiency self-adapting anti-rust dehumidifier has small volume and high efficiency, and the range of working temperature of the dehumidifier accords with the demand of army equipment.

The utility model relates to filed of air conditioning, is specifically related to a kind of efficient self-adapted antirust dehydrating unit that is used for little space environments such as cabinet, rack.

Background technology

In little spaces such as cabinet, rack, be easy to assemble moisture because of " cell breath ".When evening, temperature reduced, the gas pressure in the confined space can descend because expand with heat and contract with cold in the reduction with temperature, for the balance inside and outside differential pressure, will suck the humid air of outside from the slit.When daytime temperature raise, the gas pressure in the confined space increased with the rising of temperature, and gas inside will be by the slit to external diffusion.This " cell breath " causes the moisture turnover unequal, and in the course of time, the gas humidity in the confined space is increasing, finally causes the material surface dewfall, influences electric property, and quickens metal erosion.

The research surface, when gas humidity was lower than 65%, most metals not protection did not corrode yet, and the insulating properties of electrical equipment do not descend yet.Therefore, the humidity that controls environment has material impact to electric property and reliability.

Antirust dehumidifier is by making relative low-temperature space, utilizing condensation principle, with the water of vaporous water liquefy, gets rid of by drainpipe, thereby reduces the interior ambient humidity of confined space in the scope of safety, avoids dewfall, prevents corrosion.

But general compression refrigeration equipment volume is big, noise is big, energy consumption is high, is difficult to coupling, is placed on rack inside and need be placed on the overall structure of external action equipment than large space, also brings heat dissipation problem simultaneously.Adopt the volume of semiconductor refrigerating little, noiselessness, matching be good, but semiconductor refrigerating temperature during greater than 40 ℃ refrigerating efficiency very low, lost efficacy easily, be difficult to adapt to the wild environment condition, can not adapt to the environmental requirement of military products.For low-power equipment, cold-end temperature difference is less, and the vaporous water efficient of condensing, trickle at cold junction is low, is unfavorable for the separation of aqueous vapor.
