Title:
COMPOSITE PHASE CHANGE ENERGY STORAGE MATERIAL AND PHASE CHANGE HEAT STORAGE HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/211464
Kind Code:
A1
Abstract:
Provided are a composite phase change energy storage material and a phase change heat storage heating device. The phase change heat storage heating device comprises a housing (1), a heat dissipation assembly (2) and a heat storage unit located in the housing; the heat storage unit comprises a heat storage container (3), an electric heating element (31), a heat conduction assembly (32) and a phase change heat storage medium (33), wherein the electric heating element (31) and the heat conduction assembly (32) are both located at an inner part of the heat storage container (3), the heat conduction assembly (32) is immersed in the phase change heat storage medium (33), and the heat conduction assembly (32) and the electric heating element (31) have heat conduction; a heat exchange air duct (4) that communicates with an outer part of the housing (1) is formed between the housing (1) and the outer wall of the heat storage container (3), a first end of the heat dissipation assembly (2) extends into the heat storage container (3) and makes contact with the phase change heat storage medium (33), and a second end of the heat dissipation assembly (2) is located in the heat exchange air duct (4); and the phase change heat storage medium (33) is used to absorb heat generated by the electric heating element (31) and dissipate the heat to the outer side of the housing (1) by mean of the heat dissipation assembly (2). The present phase change heat storage heating device has a high electric energy utilization rate and high heating thermal efficiency.
