Problems solved by technology

However, the conventional cooling device for electronic equipment has increased the number of parts due to the installation of a heater for humidity control and a moisture absorbing and dehumidifying element.
In addition, existing devices require strict protection against water leakage due to the use of cooling water near electronic equipment.

Abstract

An electronic cooling apparatus has a cabinet which is opened at the front and rear sides thereof and accommodates plural electronic devices each having a fan, and a rear door which is provided with an evaporator. Air blown by the fan is cooled by the evaporator and then returned to a room. An expansion valve and an electronic component unit for controlling the expansion valve are provided integrally with the evaporator. A drain pan for receiving drain water dropping from the evaporator is provided at the lower side of the evaporator. Furthermore, an exhaust temperature detecting unit for detecting exhaust heat temperature of the electronic device and a controller for controlling the refrigerant supply to the evaporator are provided. When the exhaust heat temperature is equal to or less than a set exhaust temperature which is defined in a computer room so that no dew condensation occurs in the evaporator, the controller stops the refrigerant supply to the evaporator, and when the exhaust heat temperature exceeds the set exhaust heat temperature, the controller starts the refrigerant supply to the evaporator.

Description

technical field [0001] The present invention relates to an electronic equipment cooling system and an electronic equipment cooling device that cool air blown by a fan attached to an electronic equipment housed in a housing. Background technique [0002] Generally, an electronic equipment cooling system (for example, US Patent Application Publication No. 2006 / 0232945 specification) and an electronic equipment cooling device (Japanese Patent Application Laid-Open No. 8-316676 ) having the following structures are known, and the electronic equipment cooling system is used to house electronic equipment The air outlet side of the box is equipped with an air-water heat exchanger, and the air blown by the fan is cooled by the above-mentioned air-water heat exchanger and then returned to the room. The fan is attached to the electronic equipment housed in the box. superior. [0003] This electronic equipment cooling system is installed in a computer room, and cools servers or networ...
