It goes successively to each liquid cold plate and wastes its cold carried, more liquid refrigerants enter heat pipe evaporator, can make number
It is lower according to the interior space temperature where center, the comfort level of the interior space where improving data center.
4th, it is opposite due to being used for transmission the caliber of pipeline of refrigerant in liquid cold plate in the utility model one embodiment
It is smaller, by setting power plant (for example, fluorine pump) between each liquid cold plate and refrigerant distribution module to drive liquid system
Cryogen so that refrigerant can circulate in each liquid cold plate；Meanwhile power plant can be frequency conversion fluorine pump, may be incorporated in
Into the frequency of the flow adjustment frequency conversion fluorine pump of some liquid refrigerant of power plant, flow under the control of refrigerant distribution module
When bigger, frequency is higher, and flow is got over hour, and frequency is smaller, so as to fulfill electric energy is saved.
5th, in one embodiment of the utility model, the first distance between heat pipe evaporator and horizontal plane is less than heat pipe condenser
During second distance between horizontal plane, third distance of the refrigerant distribution module apart from horizontal plane should be more than second distance and small
In the first distance, in this way, then can make some liquid refrigerant formed in heat pipe condenser that can pass through refrigerant under the effect of gravity
Distribution module is directly entered in each heat pipe evaporator, without additional power plant to entering the part liquid in heat pipe evaporator
State refrigerant is driven, and further saves electric energy.

Some elements.In the absence of more restrictions, the element limited by sentence " including a 〃 〃 ", it is not excluded that
Also there is other identical factor in the process, method, article or apparatus that includes the element.
It is last it should be noted that：The above is only the preferred embodiment of the present invention, is merely to illustrate this practicality
Novel technical solution, is not intended to limit the scope of protection of the utility model.It is all the spirit and principles of the utility model it
Interior done any modification, equivalent substitution, improvement and etc., are all contained in the scope of protection of the utility model.
