Paraffin expanded graphite composite phase change material and manufacturing method thereof as well as off-peak electricity heat storage warmer and manufacturing method thereof

Abstract

The invention relates to a warmer and a manufacturing method thereof, in particular to a valley electricity heat storage warmer and a manufacturing method thereof. The upper ends and the lower ends of the heat dissipation pipes penetrate through an upper connecting plate and a lower connecting plate of the inner container respectively, an oil guide pipe is arranged in the space between every two adjacent heat dissipation pipes, the oil guide pipes are connected with the oil tank, and the remaining space of the inner container is filled with paraffin expanded graphite composite phase change materials. The two ends of a plurality of heat dissipation pipes are connected and penetrate through the upper connecting plate and the lower connecting plate respectively, an oil guide pipe is arranged in the space between every two adjacent heat dissipation pipes, the oil guide pipes and the oil tank form closed circulation, and any three of the front connecting plate, the rear connecting plate, the left connecting plate and the right connecting plate which form the inner container are connected with the upper connecting plate and the lower connecting plate. After the paraffin expanded graphite composite phase change material is filled in the inner container, a closed space is finally formed; the inner container is arranged in the shell, and the space between the inner container and the shell is filled with foaming heat preservation materials. Compared with the prior art, part of heat energy can be stored while heating is conducted, and heat can be continuously supplied by means of stored heat.

Description

[0001] This application is a divisional application for the invention patent of the parent application titled "Valley Electric Heat Storage Heater and Its Manufacturing Method"; the application number of the parent application is: CN201810225585.5; the application date of the parent application is: 2018.03.19 . technical field [0002] The invention relates to a heater and a preparation method thereof, in particular to a paraffin expanded graphite composite phase change material and a preparation method thereof, and a valley electricity heat storage heater and a preparation method thereof. Background technique [0003] In recent years, due to environmental protection requirements, the main energy source for heating in winter in northern my country: coal has been banned, and alternative electricity, gas, and solar energy have been widely used. Among them, electricity is the most stable and safest, so electricity costs have become a concern Focus, how to reduce electricity cost...
