Abstract

The utility model relates to a safety electric heating body, comprising heat radiating fins which are lined in order. The safety electric heating body is characterized in that the heat rradiating fins are lined on the peripheral wall of a central body in order to form a whole body with the central body, and at least one electric heating tube which is provided with an insulation jacket is arranged inside the central body. The safety electric heating body can effectively prevent electric shock or fire accident. With reasonable structure, the utility model enhances heat conduction effect and guarantees safety in use. The safety electric heating body not only can be used as a heater for direct use, but also can be used as a heat source for various warming devices.

Description

Safe electric heating body

The utility model relates to heating element, especially a kind of safe electric heating body.

The kind of existing heating element is a lot, warming oil spit of fland, electric calorifier and direct-injection type electrothermic lamp tube warmer etc. are arranged, these heating installations are that electric calorifier and direct-injection type electrothermic lamp tube warmer all were with the outside release heat of naked light mode non-naked light conducted heat except that the warming oil spit of fland.The warming oil spit of fland generally can not cause fire or burn out thing owing to adopt the outside release heat of transition heat transfer type, uses safelyr, but it exists heat transfer rate slow, and high defective consumes energy.Electric calorifier and direct-injection type electrothermic lamp tube warmer can directly discharge the heat of its generation though be exposed to outer electric calorifier resistance wire or warmer electrothermic lamp tube normally with the outside release heat of exposure chamber, have the fast advantage of heat transfer rate.But the resistance wire of warmer hot spots or electrothermic lamp tube gently then burn out thing in case contact promptly with article and can light burning, and be heavy then cause fire, and in a single day the electric heating element of exposure touches people's cognition and cause electric shock accidents.

The purpose of this utility model is the deficiency that exists at above-mentioned heating installation, and the safe electric heating body that a kind of structure is more reasonable, heat-transfer effect is splendid is provided.

Safe electric heating body of the present utility model comprises: arrange orderly fin, it is characterized in that: fin is ordered in a central body to be had on the perisporium, and constitutes one with central body, and an electric heating tube of being furnished with insulating barrier is set in the central body at least.

Safe electric heating body design principle of the present utility model is: electric heating tube is arranged in the central body of orderly arrangement fin, electric heating tube is directly heated fin, utilize fin to strengthen area of dissipation, the spacer holes of the fin of arranging then helps to form the convection current of air in order, helps the heating of safe electric heating body to its surrounding air.

Safe electric heating body of the present utility model because the electric heating body surface is not charged, is directly exposed to outer heating installation with various thermals source on the market and compares, and the safety electric heating body can prevent to get an electric shock or the generation of fire incident effectively.Its rational structure had both improved heat-transfer effect, had guaranteed to use upward safe and reliable again.The safety electric heating body both can be used as heating element directly to be used, and also can be used as the thermal source of all kinds of heating systems.

The concrete structure of the utility model safety electric heating body is provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation of safe electric heating body;

Fig. 2 is security heating pipe A-A position profile figure shown in Figure 1;

Fig. 3 is the stereogram of security heating pipe shown in Figure 1.

Embodiment: can be clear that from Fig. 1, Fig. 2 and Fig. 3, this is that a kind of external form becomes swallow-tailed safe electric heating body, be dovetail shaped on the central body 1 and arrange fin 2 in order, all leave spacer holes 3 between each fin 2, be provided with the electric heating tube 4 of two tape insulation layers in the central body 1.Described central body 1 and fin 2 are by the high conductivity material whole cast.

Claims

1, a kind of safe electric heating body, comprise: arrange orderly fin (2), it is characterized in that: fin (2) is ordered on the perisporium of a central body (1), and constitutes one with central body (1), and an electric heating tube (4) of being furnished with insulating case is set in the central body (1) at least.

2, safe electric heating body according to claim 1 is characterized in that: central body (1) and fin (2) are by the high conductivity material whole cast.

3, safe electric heating body according to claim 1 and 2 is characterized in that: be dovetail shaped on the central body (1) and arrange fin (2) in order.
