Heat-pipe type ice-storing ice-melting cold-accumulating device and ice-storing cold-accumulating air conditioner

Abstract

The invention discloses a heat-pipe type ice-storing ice-melting cold-accumulating device and an ice-storing cold-accumulating air conditioner. The heat-pipe type ice-storing ice-melting cold-accumulating device is characterized in that an ice-storing box and a secondary refrigerant box of the heat-pipe type ice-storing ice-melting cold-accumulating device are vertically arranged in a box body up and down, the secondary refrigerant box is provided with a liquid inlet and a liquid outlet, and the ice-storing box is filled with water; multiple heat pipes pass through a partition plate so as to be evenly arranged in the ice-storing box and the secondary refrigerant box, and heat transfer materials are arranged in the ice-storing box and the secondary refrigerant box; a corrugated plate or foamed metal is utilized as the heat transfer materials, a heat pipe is a cylindrical hollow circular pipe with two enclosed ends, and the internal surface of the hollow circular pipe is provided with multiple trapezoidal groove channels; and the depth of each trapezoidal groove is 0.5-1mm, and the hollow inner diameter of the heat pipe is 25-75mm. Compared with the prior art, the device provided by the invention has the advantages that the heat transfer efficiency is improved, and the flow resistance of the secondary refrigerant is small; and the heat transfer effect of the added corrugated plate or the foamed metal is improved; and the liquid in an ice-storing section exists in a brash ice mode, the phenomenon of overlong ice melting time is avoided, the corrugated plate or the foamed metal is utilized to improve the heat transfer efficiency.

Description

technical field [0001] This patent relates to a new type of ice storage and cold storage device, in particular to a heat pipe type ice storage and melting ice storage device, and the invention also relates to an air conditioner containing the heat pipe type ice storage and ice melting cold storage device. Background technique [0002] Since the world energy crisis in the last century, governments of various countries have attached great importance to "energy saving" and the development of new alternative energy sources. Because ice storage technology has multiple functions of shifting peaks and filling valleys, saving energy, protecting the environment, and greatly saving costs, it has won a lot of attention. Widely recognized by the government and users. Countries such as Europe, America, Japan, and South Korea took the lead in introducing ice storage technology into building air-conditioning systems, and the energy storage technology has been popularized and applied on a l...
