Problems solved by technology

[0002] Most of the existing gas heaters are gas directly entering the electric heater. Since the diameter of the gas inlet is much smaller than the diameter of the heating part of the heater, after the gas enters the electric heater, the air flow is turbulent, and the gas is heated with the outer ring of the heating tube bundle. The heat exchange of the element is less, and the temperature of the outer heating tube is generally high, which reduces the service life of the heating element and the utilization rate of the heat energy of the heater is not high

Abstract

The invention relates to a flow equalization device for an air electric heater. Two ends of a heater cylinder are provided with an inlet cone and an outlet cone; the inlet cone and the outlet cone are provided with an air inlet and an air outlet respectively; an electric heating tube nest is arranged in the heater cylinder; and a conical flow equalizer which is provided with flow equalization holes is fixed in the inlet cone. The conical and porous flow equalizer is arranged in the inlet cone of the heater, so that the flow field of the air is equalized and then the air enters the electric heater which efficiently exchanges heat with heated air; therefore, the energy consumption of the heater can be reduced and the service life of the whole heater can be prolonged simultaneously.

Description

technical field [0001] The invention relates to an electric gas heater, in particular to a current equalizing device for an electric gas heater. Background technique [0002] Most of the existing gas heaters are gas directly entering the electric heater. Since the diameter of the gas inlet is much smaller than the diameter of the heating part of the heater, after the gas enters the electric heater, the air flow is turbulent, and the gas is heated with the outer ring of the heating tube bundle. The heat exchange of the element is less, and the temperature of the outer heating tube is generally high, which reduces the service life of the heating element and the utilization rate of the heater's heat energy is not high. Contents of the invention [0003] In view of the above problems, the present invention provides a gas electric heater flow equalization device, which allows the gas to enter the electric heater after being uniformly flowed, which can reduce energy consumption ...
