Abstract
An electric heat-emission disc is composed of an aluminum casing, a pig iron disc body, magnesia powder and a resistance wire. The aluminum alloy casing is wrapped on the pig iron disc body; the magnesia powder is wrapped on the resistance wire; and the resistance wire coated with the magnesia powder is wrapped by the pig iron disc body; disc feet are connected with a disc body; binding posts and wring terminals are fixed on the disc body and are connected with the resistance wire. The electric heat-emission disc of the utility model has the advantages of high-temperature-deformation resistance, uniform heat emission, high heat-conduction efficiency, simplicity in process, few used materials, high production efficiency, stable product quality, safety, durability and energy-saving and environmentally friendly properties.
Description
Technical field
The utility model belongs to a kind of electric heat-generating disc.
Background technology
At present, the heat-generating disc that has comprises the aluminium disk body, and disk body is cast by aluminium, in bury and be cast with heat-generating pipe.Aluminium matter disk body is because fusing point low (aluminium begins 520 ℃ of fusion temperatures), and when work bottom temp about 350 ℃ to 430 ℃ (about 800 ℃ of resistance wire heating faces), distortion can occur after long-time the use, cause heat to spread out of, the too high and local melting of the position temperature that causes distortion.This type of life of product is short, is prone to potential safety hazard.The heat-generating disc that has comprises the cast iron disk body, and the heating tube seat is arranged in the disk body, and heat-generating pipe is pressed in the groove.Heat-generating pipe only is pressed into face and contacts with groove face, and 50% face exposes the space in addition.Heat-generating pipe and groove face are because of the gap of technology fit tolerance, and these factors all can cause heat-generating pipe and the too high heat-generating pipe that burns out of the bad easy temperature of cell wall heat conduction.The cast iron plate poor thermal conductivity, the heat efficiency is low, the wasting of resources.The heat-generating disc that has comprises disk body, and disk body is by aluminium die casting, and the disk body bottom is adopted resistance wire to add the insulating temperature resistant meterial pressing that is mixed with adhesive and formed.Disk body generates heat for a long time, and to be directed at aluminium matter heating card yielding in the work meeting, local melting.The insulating temperature resistant meterial that is mixed with adhesive uses (about 800 ℃ of resistance wire heating face) easily aging, delamination, peels off and moisture absorption electric leakage through long-time high temperature.This type of life of product is short, is prone to potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of electric heat-generating disc, the oxidized magnesium powder of the resistance wire of heat-generating disc coats to press and is the mosquito repellent coil disc shape, all casting is embedded in the pig iron disk body, pig iron disk body is loaded into the die casting aluminium alloy again, makes pig iron disc surfaces closely cover the high aluminum alloy casing of one deck conductive coefficient.Overcome the shortcoming of above-mentioned heat-generating disc, not only high temperature is indeformable for it, and heating uniform heat conduction efficient height, and technology is simple, materials are little, safety durable, energy-conserving and environment-protective.
The utility model is made up of aluminium shell, pig iron disk body, magnesia powder, resistance wire, aluminum alloy casing wraps on the pig iron disk body, magnesia powder wraps on the resistance wire and is encased by pig iron disk body, and the dish pin connects disk body, and binding post, binding post are fixed on the binding post and connect resistance wire.
The oxidized magnesium powder of the resistance wire of described heat-generating disc coats to press and is the mosquito repellent coil disc shape, comprises that also the mosquito repellent coil disc of strip resistance silk is embedded in the pig iron disk body by whole casting.Described pig iron disk body is loaded into the die casting aluminium alloy again, makes pig iron disc surfaces closely cover the high aluminum alloy casing of one deck conductive coefficient.
The utility model not only high temperature is indeformable, and heating uniform heat conduction efficient height, and technology is simple, materials are little, production efficiency is high, constant product quality, safety durable and energy-conserving and environment-protective.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model is made up of aluminium shell, pig iron disk body, magnesia powder, resistance wire, and the oxidized magnesium powder of the resistance wire of heat-generating disc coats to press and is the mosquito repellent coil disc shape, comprises that also the mosquito repellent coil disc of strip resistance silk is embedded in the pig iron disk body by whole casting.Pig iron disk body is loaded into the die casting aluminium alloy again, makes pig iron disc surfaces closely cover the high aluminum alloy casing of one deck conductive coefficient.
As shown in Figure 2, aluminum alloy casing 1 wraps on the pig iron disk body 2, and magnesia powder 3 wraps on the resistance wire 4 and encased by pig iron disk body 2, and dish pin 5 connects disk body, and binding post 6, binding post 7 are fixed on the binding post 6 and connect resistance wire.
A kind of electric heat-generating disc of the utility model, the oxidized magnesium powder of the resistance wire of described heat-generating disc coats the shape of pressing to the fragrant dish of line, the fragrant dish of line that also comprises the strip resistance silk is embedded in the pig iron disk body by whole casting, described pig iron disk body is loaded into the die casting aluminium alloy again, makes its pig iron surface closely cover the high aluminum alloy casing of one deck conductive coefficient.Owing to adopt such structure, the fragrant dish of the line of strip resistance silk heat-transfer area is big, generate heat evenly, and pig iron disk body is high temperature resistant indeformable, and the aluminium alloy heat conduction of heat-transfer area is fast, heat efficiency height.A kind of electric heat-generating disc it not only technology is simple, and materials are little, production efficiency is high, steady quality, heating uniform heat conduction efficient height, safety durable and energy-conserving and environment-protective.
