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 heat releasing unit includes heat releasing constituents which are stacked and are joined together while heat releasing flow passages are formed in the heat releasing constituents, respectively. An evaporating unit includes evaporating constituents which are stacked and are joined together, while evaporating flow passages are formed in the evaporating constituents, respectively. The evaporating unit and the heat releasing unit are arranged one after another in a direction along a side plate portion. A heat releasing unit outlet is formed at an outlet-side heat releasing constituent that is one of the heat releasing constituents placed at an end thereof. An evaporating unit inlet is formed at an inlet-side evaporating constituent that is one of the evaporating constituents placed at an end thereof. All of the heat releasing flow passages are connected to the evaporating flow passages through the heat releasing unit outlet and the evaporating unit inlet.

Abstract: A heat exchange apparatus includes a heat exchanger through which a heat exchange medium flows inside, a fluid transport device that causes the heat exchange medium to flow, and a flow path through which the heat exchange medium flows. The heat exchange apparatus includes a flow rate controller configured to increase or decrease the flow rate of the heat exchange medium flowing through the flow path, and a driving part that drives the flow rate controller by receiving a force from the flow of the heat exchange medium flowing through the flow path.
