Mixed fused salt heat accumulating type electric heater

Abstract

The invention relates to a mixed fused salt heat accumulating type electric heater which comprises an outer machine box. The outer machine box is formed by assembling of a front shell, a rear shell, a top cover and a bottom plate, an operation panel and an air outlet are arranged on the upper portion of the front shell, a wall support is arranged on the rear shell, a fan is arranged at the bottom of the rear shell, and the rear shell is fixed on a fan fixed plate, a fused salt box is arranged at a center of the outer shell, the fused salt box is full of fused salt, a heating pipe is arranged in the fused salt box, the heating pipe is fixed on the top cover of the fused salt box, and in addition, a temperature controller, a heater power source wire and a fan power source wire are arranged on the top cover of the fused salt box. Two air flues are arranged on the rear side of a fused salt box body, when hot load is big or fused salt temperature is low, an inner air flue is opened so as to increase heat dissipation amount of the electric heater, and when the hot load is small or the fused salt temperature is high, an outer air flue is opened. Rock wool thermal insulation materials are filled between the outer side of the outer air flue and an outer shell of a machine body, and between the front side of the fused salt box and the front side of the machine body, and excessive loss of heat is prevented. The mixed fused salt heat accumulating type electric heater not only reduces operation cost of the electric heater, but also relieves power grid peak valley.

Description

technical field [0001] The invention relates to a heating and heat storage device, in particular to a heat storage type air supply electric heater. Background technique [0002] Due to environmental pressure, electric heating has been paid more and more attention by people. Electric heating has the advantages of no pollution in the heating area, flexible adjustment, and convenient use. In addition, the development of society and the improvement of people's living standards have brought about drastic changes in my country's power consumption structure. The peak power is seriously insufficient, the peak-to-valley difference continues to increase, and the low-efficiency operation of generator sets during the valley period. In order to solve this contradiction, in the power The industry has put forward the measures of "cutting peaks and filling valleys", implementing peak and valley electricity prices, and encouraging electricity consumption during valley periods. The combinati...

Problems solved by technology

[0003] The heat storage medium of existing heat storage electric heaters has small heat capacity, poor heat storage capacity, and strong heat dissipation capacity, resulting in little heat supply when the heat load is large

In addition, radiation heating is generally used for heating, and its disadvantages are that the heating effect is poor and the indoor temperature is uneven; while the heating device using the wind direct blowing resistance wire method solves the above problems but has the disadvantage of large energy consumption.
