Heat exchanging device

A heat exchanging device comprising:

• a regenerator that heats an absorbent by acquired external energy and generates a vapor refrigerant by evaporating a refrigerant from the absorbent;
• a condenser that generates a liquid refrigerant by cooling and liquefying the vapor refrigerant generated by the regenerator;
• an evaporator that generates a vapor refrigerant by vaporizing the liquid refrigerant generated by the condenser and cools an object by heat of vaporization;
• an absorber that absorbs the vapor refrigerant generated by the evaporator into the absorbent;
• and
• a first cover member and a second cover member that are plate-like members arranged opposite to each other, wherein
• the evaporator absorbs heat from a space on a second cover member side in a space between the first cover member and the second cover member through the second cover member, and
• the absorber dissipates the heat from a space on a first cover member side in the space between the first cover member and the second cover member through the first cover member, and circulates the refrigerant and the absorbent.
