Description
Technical field
The utility model relates to a kind of electric heating equipment, specifically relates to a kind of evaporator of refrigerator defrost electric heating tube.
Background technology
The evaporator of commercial refrigerator or freezer is when refrigeration work, and evaporator surface can condense one deck frost, and frost is thick just has influence on evaporation endothermic, and this just needs defrost, and the commercial refrigerator large for refrigerating capacity or the large Multifunctional electric heating tube of the evaporator of freezer carry out defrost.
Because the environment for use of evaporator is more severe, atmospheric water content is larger, belong to clammy air, general electric heating tube lead-out wire position easily makes moist, one make moist electric heating tube insulation will reduce, the useful life of defrost electric heating tube will be affected like this, or because of defrost electric heating tube insulation reduction cause power circuit breaker to trip, cause refrigerator cisco unity malfunction, thus affect the use of refrigerator.
Summary of the invention
The purpose of this utility model is to provide a kind of evaporator of refrigerator defrost electric heating tube, and this electric heating tube overcomes the deficiencies in the prior art, and structure is simple, safe and reliable, can be effectively moistureproof, freeze proof, defrost is effective, ensure that refrigerator can normally use under clammy environment.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts: a kind of evaporator of refrigerator defrost electric heating tube, comprise and be located at the outer field stainless steel tube of electric heating tube, the heating wire being located at stainless steel tube inside and the extraction wire be connected with external power source, it is characterized in that: the extraction position, two ends of the heating wire in stainless steel tube inside is connected with eduction rod one end respectively, the other end of eduction rod is connected with extraction wire, modified oxidized magnesium packed layer is filled with around the heating wire of stainless steel tube inside, silicon rubber insulation sealant is enclosed with respectively at the extraction position of the stainless steel tube two ends mouth of pipe.
Preferentially, the surrounding of described extraction wire is enclosed with silicone rubber insulation layer.
Preferentially, the silicon rubber insulation sealant at the extraction position of the described stainless steel tube two ends mouth of pipe and the silicone rubber insulation layer of drawing around wire are sealed to one.
In technique scheme, owing to being filled with modified oxidized magnesium packed layer and being enclosed with silicon rubber insulation sealant respectively at the extraction position of the stainless steel tube two ends mouth of pipe around the heating wire of stainless steel tube inside, solve prior art deficiency, can effectively hydrophobic, protection against the tide, the electrothermal tube inside and outside wall at lead-out wire position is sealed to one completely with extraction wire insulation, effectively preventing electric heating tube lead-out wire position low because insulating after poorly sealed making moist, extending heating tube useful life.The utility model has following beneficial effect: the first, overcomes the deficiencies in the prior art, and structure is simple, and cost is low; The second, safe and reliable, can be effectively moistureproof, freeze proof, defrost is effective, ensure that refrigerator can normally use under clammy environment; 3rd, the utility model defrost electric heating tube can directly be contained in evaporator of refrigerator inside, avoids the electric heating tube understood because adopting flange method to install and needs to change the structure of refrigerator inside, the structure of evaporator and even increase hot air duct requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of evaporator of refrigerator defrost of the utility model electric heating tube;
Fig. 2 is the amplification assumption diagram that in a kind of evaporator of refrigerator defrost of the utility model electric heating tube, the electric heating tube mouth of pipe draws position.
Embodiment
Below in conjunction with drawings and Examples, a kind of evaporator of refrigerator defrost of the utility model electric heating tube is described in further detail.The accompanying drawing forming the application is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.
From Fig. 1, Fig. 2, a kind of evaporator of refrigerator defrost of the present embodiment comprises the extraction wire 3 being located at the outer field stainless steel tube 1 of electric heating tube, being located at the heating wire 2 of stainless steel tube 1 inside and being connected with external power source with electric heating tube, the extraction position, two ends of the heating wire 2 in stainless steel tube 1 inside is connected with eduction rod 4 one end respectively, the other end of eduction rod 4 is connected with extraction wire 3, around the heating wire 2 of stainless steel tube 1 inside, be filled with modified oxidized magnesium packed layer 5, be enclosed with silicon rubber insulation sealant 6 respectively at the extraction position of the stainless steel tube 1 two ends mouth of pipe.The surrounding of drawing wire 3 is enclosed with silicone rubber insulation layer 7.In the present embodiment, the silicon rubber insulation sealant 6 at the extraction position of the stainless steel tube 1 two ends mouth of pipe and the silicone rubber insulation layer 7 of drawing around wire 3 are sealed to one.
In the present embodiment, by defrost electric heating tube specification (voltage, power) prepare heating wire 2, to burn-on eduction rod 4, special powder-filling machine fro is encased in stainless pipe 1, and make modified oxidized magnesium packed layer 5 fill closely knit, again stainless steel tube 1 differential annealing is curved required shape, line up carries out pipe cutting, after digging the preliminary treatment such as powder, put into abundant oven dry of high temperature roaster and remove tide, the clean mouth of pipe position of cleaning, connect and need length, the wire being enclosed with silicone rubber insulation layer 7 of mesh power size is as extraction wire 3, be seated in special mould with heat vulcanized silicone rubber after the port sealing position of stainless steel tube 1 is coated with polymer agent, mold pressing is also heated to curing temperature, insulation makes electrically insulating silicone rubber full cure shaping.Naturally lay down mould after cooling, such silicon rubber insulation sealant 6 is just completely by integral for the complete environmental sealing of the mouth of pipe of silicone rubber insulation layer 7 to the stainless steel tube 4 of drawing wire 3.The present embodiment overcomes the deficiencies in the prior art, structure is simple, cost is low, safe and reliable, can be effectively moistureproof, freeze proof, defrost is effective, ensure that refrigerator can normally use under clammy environment, defrost electric heating tube can directly be contained in evaporator of refrigerator inside, avoids the electric heating tube understood because adopting flange method to install and needs to change the structure of refrigerator inside, the structure of evaporator and even increase hot air duct requirement.
The above; it is only embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent method change, all still belong in the protection range of technical solutions of the utility model.
