Title:
MOBILE PHASE-CHANGE HEAT AND COLD STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/139122
Kind Code:
A1
Abstract:
Disclosed is a mobile phase-change heat and cold storage device, comprising a heat transfer plate (3), a support (5), a sleeve (6), a header pipe (2), a storage tank (1) and a phase-change working medium (4). The heat transfer plate (3) is the main element in heat exchange, and the storing and releasing of heat provide a connection between the heat and cold storage device and the outside by means of the phase-change working medium (4), the header pipe (2) and the sleeve (6). In a heat storage process, steam flows through the heat transfer plate (3) by means of the header pipe (2), and heat is transferred to the phase-change working medium (4) by means of the heat transfer plate (3), such that the phase-change working medium absorbs heat and is liquefied to store heat and same is transported to a designated position in a box body (8), cold water flows through the heat transfer plate (3) by means of the sleeve (6), heat is transferred from the phase-change working medium (4) to the cold water by means of the heat transfer plate (3), and the phase-change working medium (4) releases heat and solidifies to release heat; and the cold storage process is similar to the heat storage process. The mobile phase-change heat and cold storage device can stably output heat or cold energy at an expected temperature, making the efficiency of the heat and cold storage device higher, and the application range of same is wide.
