Flexible cold and heat exchange device

Abstract

The invention relates to the technical fields of heat collection and dissipation of solar energy and natural cold energy, in particular to a flexible cold and heat exchange device. The flexible cold and heat exchange device comprises a bearing structure and multiple strip-shaped water containing bags, wherein the strip-shaped water containing bags are connected into a whole to form heat exchange bodies; the bearing structure comprises strip-shaped beams, the extending direction of the strip-shaped beams is consistent with that of the strip-shaped water containing bags, and the multiple strip-shaped water containing bags and the strip-shaped beams are combined together in a movable connection mode. The strip-shaped beams of the bearing structure are used for laying out the heat exchange bodies composed of the strip-shaped water containing bags to a set space position, the strip-shaped water containing bags filled with water are arranged in a multi-layer and multi-row mode, and in this way, more heat exchange bodies can be arranged in a limited space of a cold and heat exchange facility. The cold and heat exchange function of the flexible cold and heat exchange device is more powerful, the cold and heat exchange cost is reduced, cold and heat exchange efficiency is improved, and the flexible cold and heat exchange device is convenient for a user to use.

Description

technical field [0001] The invention relates to the technical field of heat collection-radiation of solar energy and the technical field of collection-radiation of natural cold energy, in particular to a flexible cooling and heat exchange device. Background technique [0002] In the production of greenhouse vegetables in winter, the indoor temperature is high during the day on sunny days, and some hot air (that is, solar energy) needs to be ventilated to the outside. At night or even cloudy days, the temperature inside the greenhouse is low but there is no energy supplement. When it appears, it will also cause chilling or freezing damage to vegetables in the greenhouse. In order to solve this problem, a large-volume water bag is installed on the ground or wall of the greenhouse to continue solar energy during the day and to supplement indoor heat at night or on continuous cloudy days to maintain an appropriate temperature and protect vegetables from freezing damage. .

Problems solved by technology

[0008] First, the specific surface area of ​​the container is small, that is, compared to the capacity of the energy storage medium, the surface area of ​​the container to receive heat or cold energy in the environment is small, so the efficiency of absorbing heat or cold energy is low The efficiency of releasing heat or cold energy in the environment is also low

[0009] Second, the volume of the cavity of the container is too large, and the dis
