Abstract: A cooling device includes a cooling tank, a liquid storage tank, and a connector. The cooling tank stores refrigerant liquid for immersing and cooling a heating element. The liquid storage tank stores the refrigerant liquid outside the cooling tank and has an atmosphere opening portion. The connector connects the two tanks and allows the refrigerant liquid to pass through the connector. One end of the connector has a cooling-tank opening portion located in a gravity direction at a position lower than or same as a liquid level of the refrigerant liquid. An upper portion of the cooling tank stores a gas generated in the cooling tank. The refrigerant liquid flows between the two tanks via the connector in accordance with a change in volume of the gas. The liquid storage tank is provided upward of the cooling tank. The two tanks are connected only by the connector.

Abstract: A refrigerant heat exchanger has the passage defining member. The passage defining member is made of carbon fiber reinforced plastics. The passage defining member has a tube portion defining a refrigerant passage. The passage defining member has the plate portion which spreads from the tube portion. In the tube portion, carbon fibers are oriented to surround the tube portion. This orientation contributes to a pressure resisting performance in a radial direction of the tube portion. In the plate portion, the carbon fibers are oriented to protrude from the tube portion. This orientation contributes to improve mechanical strength in the plate portion. The carbon fibers are extended over both the tube portion and the plate portion. This orientation promotes thermal transfer over the tube portion and the plate portion.
