Abstract

The utility model relates to a heat insulation electric heating coil including a housing. The housing is C-shaped as a whole. Electric heating pipes are uniformly arranged in the housing. The outer surface of the housing is covered with a heat insulation layer. Two ports of the heat insulation layer are fixed with bolts. A mounting hole is disposed in the middle of each bolt. Connecting columns pass through the two mounting holes so that the position of the heat insulation layer is fixed. According to the utility model, the heat insulation layer can save heat produced by an electric heat tube, the heat diffusion is greatly reduced and the efficiency of heat utilization is improved significantly.

Description

A kind of heat preservation electric heating circle
Technical field
The utility model relates to electric heating coil, is specifically related to a kind of heat preservation electric heating circle.
Background technology
Electric heating coil is mainly to be applied in industrial production as heater element, for example, in the application of injection machine.The main heat exchange pattern that adopts of current electric heating coil heating, by electrothermal tube as thermal source, the light and heat of its production, by insulant and collective, heat is transmitted on heated equipment, more indirectly heat is transmitted on working medium to be heated, but because heat can't be preserved, very easily be diffused in surrounding air, cause heat utilization efficiency low, energy waste is serious.
The utility model content
For the present situation of above-mentioned prior art, the heat preservation electric heating circle that provides a kind of heat utilization efficiency high is provided technical problem to be solved in the utility model.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of heat preservation electric heating circle, comprise housing, described housing integral body is " C " font, electrothermal tube evenly is installed in housing, housing outer surface is coated with heat-insulation layer, this heat-insulation layer two-port is fixed with bolt, is provided with fixing hole in the middle of each bolt, thereby passes the fixedly position of heat-insulation layer of two fixing holes by joint pin.
Further, fill heat-preservation cotton in described heat-insulation layer.
Compared with prior art, the utility model has the advantage of: the heat that heat-insulation layer of the present utility model can produce electrothermal tube is preserved, and has greatly reduced heat diffusion, and heat utilization efficiency significantly improves.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing, embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of heat preservation electric heating circle, comprise housing 1, described housing 1 integral body is " C " font, the interior even installation electrothermal tube 2 of housing 1, housing 1 outer surface is coated with heat-insulation layer 3, these heat-insulation layer 3 two-port are fixed with bolt 4, be provided with fixing hole in the middle of each bolt 4, thereby pass the fixedly position of heat-insulation layer 3 of two fixing holes by joint pin 5, the interior filling heat-preservation cotton of described heat-insulation layer 3, the heat that heat-insulation layer of the present utility model can produce electrothermal tube be preserved, greatly reduced heat diffusion, heat utilization efficiency significantly improves.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, it will be understood by those of skill in the art that its technical scheme that still can put down in writing aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution break away from spirit and the scope of each embodiment technical scheme of the utility model.

Claims (2)
