Abstract
The utility model relates to an electric heater, specifically to an aluminium tube defrosting electric heater for performing heating defrosting in the refrigerating device and the like devices. The aluminium tube defrosting electric heater includes a flexible heating element, wherein joints that can be connected to the power supply are provided on both ends of the heating element, the heating element is composed of a fiberglass component wire located in the center, a resistance wire winded on the fiberglass component wire, and a silicon rubber insulation layer cladding outside the periphery of the fiberglass component wire and the resistance wire; and the heating element perforates the center of an aluminium tube. Compared with the traditional stainless steel tube type electric heater, the utility model does not need to stuff the oxygenation magnesium powder, to obtain more fine heater external diameter, so that it is easier to apply in a small space; because the aluminum tube has favorable plastic deformation capability, it can be bent into a skeleton structure with complicated shape, to improve is adaptability to different spatial shapes; in addition, the aluminium tube has better thermal conduction performance and improved defrost heating efficiency than the stainless steel material.
Description
Technical field
The utility model relates to a kind of electric heater, specifically is a kind of aluminum pipe formula defrosting electric heater that heats defrosting in devices such as refrigeration plant.
Background technology
Traditional defrosting electric heater that is used for refrigerator electrical equipment adopts two kinds of structures usually: a kind of is to adopt stainless steel tube as shell, and the magnesia powder of inner heater element by filling in the middle of shell and the heating wire comes out to defrost with heat transferred; Also having a kind of aluminium foil electric heater is to be used for household electric refrigerator defrosting, is heater wire is placed in the middle of two layers of aluminium foil, is applicable to the defrosting electric heater that the plane wall type uses.And for requiring in the chivalrous little space with definite shape, heat effectively and defrost, above-mentioned stainless steel tube electric heater is made difficulty because of caliber less than 6 millimeters heater, and coefficient of safety is not high, on using certain limitation is arranged.Aluminium foil type defrosting electric heater can only be applicable to planar structure in addition, can't heat defrosting to some special spaces.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and not only can be used for narrow space, but also can adapt to the aluminum pipe formula defrosting electric heater of different spaces shape heating.
Aluminum pipe formula defrosting electric heater of the present utility model includes the heating line of a flexibility, heating line two ends are provided with the joint that can connect power supply, and the heating line is made up of the glass fibre heart yearn that is positioned at the center, the resistance wire on the glass fibre heart yearn, the silicone rubber insulation layer that is coated on glass fibre heart yearn and resistance wire periphery; Described heating line passes from the center of an aluminum pipe.
The joint at described heating line two ends is together to be wrapped in many copper wires in the resistance wire with the glass fibre heart yearn.
The utility model is compared with traditional stainless steel tubular type electric heater, need not to fill magnesia powder, and is right with the thinner heater external diameter of acquisition (it is following that the aluminum pipe external diameter can reach 4mm), thereby is easy to be applied in the narrow space; Because aluminum pipe has good plastic deformation ability, can make the skeleton structure that is bent into complicated shape, has improved its adaptive capacity to the different spaces shape; In addition, aluminum pipe has the heat-conductive characteristic better than stainless steel material, has also improved the efficient of defrosting heating.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, this aluminum pipe formula defrosting electric heater includes the heating line of a flexibility, heating line two ends are provided with the joint that can connect power supply, and the heating line is made up of the glass fibre heart yearn 1 that is positioned at the center, the resistance wire 2 on the glass fibre heart yearn, the silicone rubber insulation layer 3 that is coated on glass fibre heart yearn and resistance wire periphery; Heating line 1 passes from the center of an aluminum pipe 4.The joint at heating line two ends is together to be wrapped in many copper wires 5 in the resistance wire with the glass fibre heart yearn.
Claims (2)
1. aluminum pipe formula defrosting electric heater, include the heating line of a flexibility, heating line two ends are provided with the joint that can connect power supply, it is characterized in that: the heating line is made up of the glass fibre heart yearn (1) that is positioned at the center, the resistance wire (2) on the glass fibre heart yearn, the silicone rubber insulation layer (3) that is coated on glass fibre heart yearn and resistance wire periphery; The heating line passes from the center of an aluminum pipe (4).
