Estimating the term…
In a cooling device including a pump, a heat absorber, a heat radiator, a flow channel that allows communication between interiors thereof and forms a closed-loop circulating cycle therebetween, and a liquid refrigerant that circulates in the flow channel, a volume of a gas generated in the liquid refrigerant owing to temperature change within an operating temperature range of the liquid refrigerant is smaller than a volume of a sphere that is inscribed in a cross-section of the flow channel. In this way, even when the solubility changes due to rapid heating or cooling of the liquid refrigerant, no gas is generated in the liquid refrigerant. Thus, it is possible to provide a cooling device that maintains an excellent cooling effect even after a long time use.
A cooling device comprising:
A cooling device comprising:
A method for manufacturing a cooling device comprising a pump, a heat absorber, a heat radiator, a flow channel that allows communication between interiors of the pump, the heat absorber and the heat radiator and forms a closed-loop circulating cycle therebetween, and a liquid refrigerant that circulates in the flow channel;
