Problems solved by technology

[0003] During the heating process, especially when the volume of the heater is large, the heat conduction effect of the air itself is poor, so only the part of the air that is in contact with the electric heating tube shell or the fin is heated, and a considerable part of the high-speed flowing air is not in contact with it. When the heat dissipation element is in contact, it can only be heated by the high-temperature hot air that has been heated around, so that the air discharged from the heater outlet contains multiple airflows of different temperatures, resulting in the disadvantage of uneven heating effect

Embodiment Construction

[0029] The following will describe in detail with reference to the drawings in the embodiments of the present invention.

[0030] see figure 1 , a heater for an air duct with uniform heating, which mainly includes: a cylindrical air duct 1 arranged along the horizontal direction; the inner wall of the air duct 1 is connected with a plurality of rows of cooling fin groups arranged along the axial direction, each A row of cooling fin groups is composed of a number of fins 3 set parallel to each other, and the axis of each fin 3 and the air duct 1 is provided with an inclination angle, which constitutes the fan blade of each fin 3 in the air duct 1 as an axial fan. Shaped setting; run through the electric heating tube 4 in the center of each row of heat dissipation fin groups, each electric heating tube 4 is arranged parallel to the axis of the air duct 1; the inner wall of the air duct 1 is provided with a wire hole corresponding to any end of each electric heating tube 4 , The...

Abstract

The invention relates to an electric heater, in particular to a heating-uniform air way heater. The heating-uniform air way heater mainly comprises a cylindrical air way provided with openings at twoends and horizontally arranged; a filter screen is arranged in the opening at any one end; multiple electric heating pipes are uniformly distributed in the air way in the peripheral direction; the electric heating pipes are arranged parallel to the axis of the air way; each electric heating pipe is fixedly connected with the inner side wall of the air way through fins; and all the fins in the airway are arranged in a blade shape of an axial flow fan. Under the effect of an air power module in the heater, air generates rotational currents in the heating process to achieve a more uniform heating effect.

Description

technical field [0001] The invention relates to an electric heater, in particular to a heater for an air duct with uniform heating. Background technique [0002] Air duct electric heaters are used to heat the air in industrial air ducts, air conditioning ducts and air channels of various industries to increase the temperature of the output air, and are generally inserted in the lateral openings of the air ducts. According to the working temperature of the air duct, it can be divided into low temperature, medium temperature and high temperature; according to the wind speed in the air channel, it can be divided into low wind speed, medium wind speed and high wind speed. According to the structural characteristics, the heat dissipation of the electric heating tube shell and the heat dissipation of the fins are divided. [0003] During the heating process, especially when the volume of the heater is large, the heat conduction effect of the air itself is poor, so only the part o...
