Boil cooling device

Abstract

A boiling and cooling device comprising a first and second refrigerant loop is provided. The first and second refrigerant loops are independently forming the evaporator, condenser and refrigerant pipes. The evaporator evaporates the refrigerant by boiling via the heat exchange between the internal air and the refrigerant; because the inner air in the case body is cooled, the condenser makes refrigerant condense through the hot exchange between refrigerant and outside air; so heat of refrigerant emits in the outside air of the body of case; the refrigerant is worthy of being in charge of forming the route that makes refrigerant circulate between evaporimeter and condenser; the first and second refrigerant loops are respectively provided with the electromagnetic valve stopping the refrigerant, which is provided with the inner temperature detecting device for detecting the inner temperature in the detecting case body. Thereby, even the outer temperature of the case body is extremely low,the invention also can reduce the change of the temperature in the case body, which can avoid the heat lost generated by the situation of heating the case body by the heater.

Description

boiling cooling device technical field The present invention relates to an ebullient cooling device for cooling the air inside a box, and relates to an ebullient cooling device for controlling the temperature of air in an office of a mobile phone communication network base station, for example. Background technique For example, at a mobile phone communication network base station, heat from electronic equipment such as communication equipment housed in the office must be discharged outside the office. In addition, in order to protect electronic equipment from temperature threats such as thermal shock, it is required to create a stable environment with little temperature change in the office. In view of this, in the past, in order to cool the internal air of the office, for example, as described in Japanese Patent Application Laid-Open No. 2005-140464 and Patent No. 3082669, an ebullient cooling device is installed in the office, and, for example, in Patent No. 3082669 It...

AI Technical Summary

Problems solved by technology

Therefore, when the outside air temperature drops, using the control method of reducing the fan speed, even if the fan speed is reduced, the cooling capacity of the ebullient cooling device will still exceed the heat that the ebullient cooling device can handle, so the office may be in an overcooled state. , there was a problem of not being able to maintain the desired temperature in the office

Similarly, when the outside air temperature drops, the fan is in the OFF state. According to the temperature in the office, in the ON-OFF control of switching the ON-OFF state of the fan, when the fan is operating, the office is in an overcooled state. The problem of increasing temperature fluctuations in the office

In addition, although the method of shortening the ON-OFF cycle is also considered, the buzzing noise of the fan will be generated every time the ON-FF operation of the fan is switched. Therefore, the disadvantage of this method is that it will cause other problems such as noise disadvantages. the occurrence of problems

In addition, when it is extremely cold, although the office is heated, in terms of the principle of boiling cooling, the heat will be discharged outside the office through the natural circulation of the refrigerant, resulting in the disadvantage of a delay in temperature rise.

That is to say, for example, when the temperature in the office falls below a predetermined temperature, the electronic equipment is stopped, and in order to start the electronic equipment that has been stopped, it will be in a control situation that the office is heated with a heater. When the heater is arranged on the upstream side of the air flow of the evaporator, when the air heated by the heater passes through the evaporator, its heat is taken away by the refrigerant, so the temperature in the office may reach the temperature in which the electronic equipment is started. Temperature takes a certain amount of time
