Abstract

The utility model discloses an electrothermal heat pipe heat-air furnace; a cone snap ring arranged at the bottom of the heat absorption section of the electrothermal heat pipe is sheathed in the fork hole of the pipe sheet; the heat releasing section of the heat pipe fin is arranged in a hot-air generating chamber having a cover that is arranged at the upper part of the pipe sheet; the bottom of the heat pipe is provided with an electrothermal element, which is supplied to the working substance arranged in the heat pipe for absorbing quantity of heat to vaporize; a superconducting phase converting heat is arranged at the heat releasing section of the high-frequency welding fin of the hot-air generating chamber; the latent heat of condensation is released under the flushing of the draught fan airflow, and the air is heated rapidly.

Description

The electrical heating heat pipe hot-blast stove

The utility model belongs to the electrical heating air-heating furnace.

Existing electrical heating hot-blast stove adopts light pipe or adds hot-air around the chip electric heating tube in the air channel, and the former area of dissipation is little, and the latter is around the virtual contact of sheet, and thermal resistance is big, and tube wall temperature is up to 500-700 ℃, easy burn-out, and the hot-blast stove thermal efficiency is only about 70%.

The purpose of this utility model: the novel and efficient electrical heating heat pipe hot-blast stove that a kind of ratio-frequency welding fin heat pipe of in-built electrical heating element heater is provided.

The utility model is made up of the Electric Appliance Cabinet (3) of hot-air generation chamber (2) bottom on tube sheet (1) top, heat pipe (4) endotherm section of taper snap ring edge cover is installed in tube sheet (1) fork round, is installed on tube sheet (1) top and stretch into heat pipe (4) the ratio-frequency welding fin heat release section that top has the hot-air generation chamber (2) of top cover (11); Endotherm section lower end base plate (5) is gone up the electrical heating elements (6) that binding post passes base plate (5) is installed in heat pipe (4) pipe, inject working medium, be evacuated, at hot-air generation chamber (2) one ends blower fan (7) is installed, electric heating system (8) is received automatic control box (9) by Y type mode, whole heat exchange casing (10) is incubated with silicate aluminum board, the color steel outsourcing.

During the utility model work, connect power supply, starting fan (7), restart electric heating system (8), heat pipe (4) endotherm section absorbs the heat of electrical heating elements (6), the working medium vacuum and low temperature absorbs latent heat of vaporization vaporization, poor by small temperature (pressure), with the speed of Ultrasonic wave like speed with heat delivery to the heat pipe that places hot-air generation chamber (2) (4) ratio-frequency welding fin heat release section, wash away down release condensation latent heating air fast at blower fan (7) cold airflow, condensation working medium, moves in circles to the vaporization of absorbing heat again of heat pipe bottom endotherm section by gravity reflux.

Figure one is the utility model structural representation

(1) is tube sheet among the figure; (2) be the hot-air generation chamber; (3) be Electric Appliance Cabinet; (4) be heat pipe; (5) be base plate; (6) be electrical heating elements; (7) be blower fan; (8) be electric heating system; (9) be automatic control box; (10) be the heat exchange casing; (11) be top cover.

The utility model electrical heating heat pipe hot-blast stove: tube sheet (1), hot-air generation chamber (2), Electric Appliance Cabinet (3), base plate (5), casing (10), top cover (11) are made of steel plate; Electrical heating heat pipe (4) is used steel pipe manufacturing; Electrical heating elements (6), blower fan (7), automatic control box (9) are outsourcing.

The utility model is installed thermocouple temperature sensor at hot-air generation chamber (2) hot-blast outlet place, the blast volume controller of temperature controller on the automatic control box (9) and blower fan (7) and electrical heating elements (6) are carried out interlocking, realizes fully automatic operation.
