Abstract
A cooling device boiling and condensing refrigerant includes a refrigerant container, a header tank, and tubes between the refrigerant container and the header tank. In the cooling device, each of the refrigerant container and the header tank has a stack structure constructed by stacking plural plates. Each plate is a press member formed by punching a metal plate using a press die. Accordingly, each capacity of the refrigerant container and the header tank can be readily changed in accordance with a thermal load, and the plates having the same shape can be used in common for both the refrigerant container and the header tank.
Claims22
A cooling device for cooling a heat-generating member, comprising:
- a refrigerant container constructed by stacking a plurality of plates for defining a space where refrigerant is stored, the plurality of plates including a first plate to which the heat-generating member is attached, a second plate disposed opposite to the first plate and at least a third plate between the first plate and the second plates;
- and
- a heat radiation core including;
- a plurality of tubes attached to the second plate of the refrigerant container substantially vertically to a surface of the second plate, to communicate with the space of the refrigerant container;
- and
- a header tank constructed by stacking a plurality of plates, through which the tubes communicate with each other;
- wherein:
- the refrigerant container and heat radiation core are disposed in such a manner that, refrigerant is boiled by receiving heat from the heat-generating member attached to the first plate of the refrigerant container, and the boiled refrigerant flows into the tubes to radiate heat to outside in the heat radiation core;
- the plurality of tubes includes first tubes each having an insertion length inserted into the header tank, and second tubes each having an insertion length inserted into the header tank, smaller than that of each first tube;
- and
- each first tube protrudes from an inner surface of the header tank inside the header tank by a predetermined length.
