Abstract

The present invention provides a heat insulating composite material having cold storing capacity, which includes a heat insulating member and a cold storing member adhered to the heat insulating member. The cold storing member is obtained by allowing an absorbent material to absorb a cold storing liquid. The heat insulating composite material can be made into a board to directly adhere to the inner wall of a container, or can be made into a block to place in a container. When the heating insulating composite material is placed in a container, the insulating member is allowed to contact with the object to be cooled, such that the objectives of controlling the cold releasing rate and cold storing capacity can be both achieved. The thickness of the insulating member and the cold storing liquid amount can be adjusted freely in order to control the temperature of the object as required, which is very convenient. In addition, since the cold storing liquid is absorbed by the absorbent material, the cold storing liquid will not be flowable after being melted. This can prevent uneveness of the melted cold storing liquid, and the local high temperature in the container can also be prevented.
