Abstract
A cooling device capable of preventing inflow of bubbles to a pump even in a zero-gravity space and a space structure including the cooling device are obtained. In a cooling device, a pump, a cooler, and a radiator are connected sequentially by a refrigerant flow path. An accumulator is connected to the refrigerant flow path connecting the pump and the radiator. The accumulator includes a container storing refrigerant, a cooling section cooling a base-end side of the container, and a heating section heating a front-end side of the container.

A cooling device comprising:
- a pump for circulating refrigerant by boosting pressure of the refrigerant;
- a cooler for evaporating the refrigerant pumped from the pump;
- a radiator for condensing the refrigerant evaporated by the cooler;
- a refrigerant flow path sequentially connecting the pump, the cooler, and the radiator;
- and
- an accumulator comprising:
- a container for storing the refrigerant;
- a cooling section for cooling a base-end side of the container;
- and
- a heating section for heating a front-end side of the container,
- the base-end side of the container being connected to the refrigerant flow path connecting the pump and the radiator,
- wherein the cooling section cools the container by bringing the container into thermal contact with the refrigerant flow path on an outlet side of the pump.
