Solid electric heat storage device

Abstract

The invention discloses a solid electric heat storage device which comprises a heat storage body. A plurality of heat storage brick layers are arranged in the heat storage body, the adjacent heat storage brick layers are arranged in staggering mode, a plurality of heat storage bricks are arranged in each heat storage brick layer, at least one main ventilation channel used for heating and heat dissipating is arranged on each heat storage brick, and the main ventilation channels of the heat storage bricks in one layer are communicated to form a communicated ventilation channel. The solid electric heat storage device reasonably improves structure mode and distribution mode of the heat storage bricks and enables the whole heat storage body to be even and quick in heat absorption and release due to the fact that the ventilation channels of the adjacent heat storage bricks are communicated to form a main channel and an auxiliary channel for absorbing heat and dissipating heat, saves installed capacity of a low voltage transformer, improves heat efficiency and reduces operation cost.

Description

technical field [0001] The invention relates to the field of electric heat storage hot water boilers, in particular to a solid electric storage device for converting stored heat into hot water. Background technique [0002] Electric heat storage hot water boilers in the prior art are mainly used for heating and bathing. The heat storage forms include direct heating electric hot water boilers, which circulate the hot water in the normal pressure heat preservation water tank through the hot water circulation pump, and turn the water tank into water again and again. Heating hot water, or using electric heating tubes to directly heat the water in the sealed pressure tank to a certain pressure of high-temperature water to store heat, and then output the stored heat in the form of hot water at the required temperature through heat exchange when needed , to achieve heating and bathing. Another form is to use heat storage materials to store the heat energy converted from electric e...

Problems solved by technology

At present, there are mainly two types of low-pressure solid heat storage devices and high-pressure solid heat storage devices on the market. Due to the defects in the structural design and installation of magnesia sintered bricks, the heat storage body of the existing solid electric heat storage electric heater Inhomogeneous heat absorption and heat release can easily cause some electric heating elements to burn out due to excessive temperature, which increases operating costs; and the circulating air duct is not equipped with a gas expansion port, so that the gas in the air duct increases with the temperature of the heat storage body. High and inflated, the excess gas will overflow from the connection of the air duct after expansion, resulting in partial heat loss, thereby reducing the thermal efficiency of the whole machine
