Liquid circulation type cooling system

Abstract

A liquid circulation type cooling system includes a circulating pump for circulating a liquid, a heat exchanger disposed in a heat radiation space and for radiating heat outside the system. The heat exchanger contains a core unit, a liquid reservoir for storing the liquid positioned on the upstream side of the core unit and having a liquid opening, another liquid reservoir for storing the liquid and positioned on the downstream side of the core unit, the other liquid reservoir having a liquid opening, a heat-receiving member, a piping, and a fan for supplying air to the heat exchanger to effect forced air-cooling.
