Abstract

The invention relates to a modular phase-change heat storage and supply unit and a production method thereof. The modular phase-change heat storage and supply unit comprises a heat storage base body, metal fin plates and a metal casing, wherein one metal fin plate is arranged on each of upper and lower sides of the heat storage base body, the heat storage base body and the two metal fin plates are coated with the metal casing to form an independent heat storage and supply unit, the heat storage base body comprises a shaped composite phase-change material and copper tubes inserted in the shaped composite phase-change material, water flow channels are arranged in the copper tubes, and gaps between the metal fin plates are air channels. Compared with the prior art, the obtained heat storage base body has the advantages that the copper tubes and the composite phase-change material are closely contacted, so that the contact heat resistance is greatly reduced, and the heat storage base body has the higher heat exchange coefficient and heat exchange efficiency. According to the obtained modular phase-change heat storage and supply unit, after heat storage is completed once, the stored heat can be used for hot water supply as well as heating supply, and the unit can be used for developing a novel indoor heat exchange terminal with a heat storage function.

Description

technical field [0001] The invention relates to the technical field of thermal energy storage, in particular to a modularized phase-change heat storage and heat supply unit based on organic matter / expanded graphite composite phase-change materials and a manufacturing method thereof. Background technique [0002] Nowadays, with the development of society, people's demand for energy is increasing, and the money cost and environmental cost paid in the process of energy utilization are also increasing. In 2014, the share of total building energy consumption in my country's total energy consumption has exceeded 30%, while HVAC energy consumption accounts for about 50% of building energy consumption, so HVAC energy saving is the focus of building energy conservation. In addition, only 1% of the existing buildings in our country are energy-saving buildings, and there is a huge space for energy-saving. my country has abundant solar energy resources, and the national average annual ...
