Heat-receiving device, cooling device, and electronic device

A heat-receiving device comprising:

• a heat receiver comprising:
• a case that receives heat from a heat-generating part;
• a flow path that includes first and second branch paths branch off from each other and are joined again, that is provided within the case, and through which the refrigerant flows;
• and
• a thermostat that is provided in the first branch path at a downstream side with respect to a center of a length of the first branch path, and that reduces a flow rate of the refrigerant flowing through the first branch path as a temperature of the refrigerant flowing through the first branch path decreases.

A cooling device comprising:

• a heat-receiving device including:
• a first heat receiver into which a refrigerant flows, and that receives heat from a heat-generating part;
• and
• a second heat receiver into which the refrigerant discharged from the first heat receiver flows, and that receives heat from the heat-generating part or another heat-generating part;
• a heat-generating part;
• and
• a printed circuit board on which the heat-generating part is mounted,
• wherein the first heat receiver includes:
• a case;
• a flow path that includes first and second branch paths branch off from each other and are joined again, that is provided within the case, and through which the refrigerant flows;
• and
• a thermostat that is provided in the first branch path, and that reduces a flow rate of the refrigerant flowing through the first branch path as a temperature of the refrigerant flowing through the first branch path decreases.

An electronic device comprising:

• a heat-receiving device including:
• a first heat receiver into which a refrigerant flows, and that receives heat from a heat-generating part;
• and
• a second heat receiver into which the refrigerant discharged from the first heat receiver flows, and that receives heat from the heat-generating part or another heat-generating part;
• a heat-generating part;
• a printed circuit board on which the heat-generating part is mounted;
• and
• a housing that houses the heat-receiving device, the heat-generating part, and the printed circuit board,
• wherein the first heat receiver includes:
• a case;
• a flow path that includes first and second branch paths branch off from each other and are joined again, that is provided within the case, and through which the refrigerant flows;
• and
• a thermostat that is provided in the first branch path, and that reduces a flow rate of the refrigerant flowing through the first branch path as a temperature of the refrigerant flowing through the first branch path decreases.
