Cooling device and electronic apparatus

An electronic apparatus that includes an electronic component including a heat source and a cooling device thermally connected to the heat source,

• wherein the cooling device comprising:
• a first passage configured such that the heat medium before being heated by the heat source flows through the first passage;
• a second passage configured such that the heat medium after being heated by the heat source flows through the second passage;
• a plurality of heat exchanging chambers each configured such that in the heat exchanging chamber, the heat medium is heated by heat generated by the heat source;
• a first communicating passage provided in each of the plurality of heat exchanging chambers and configured such that through the first communicating passage, the first passage and the heat exchanging chamber communicate with each other;
• a second communicating passage provided in each of the plurality of heat exchanging chambers and configured such that through the second communicating passage, the heat exchanging chamber and the second passage communicate with each other;
• and
• a flow regulating mechanism provided in each of the plurality of heat exchanging chambers and configured to regulate, according to a temperature, a flow rate of the heat medium flowing through at least one of the first communicating passage and the second communicating passage.
