Abstract
An aluminum tube for PTC heaters belongs to the technology of electrical heating, especially the technology of the PTC heater. The aluminum tube of the PTC heater is a hollow and prolate tube, and is characterized in that: the edges of the upper surface and the lower surface are installed with an introvert structure which is heaved and curved inward along the direction of length. The introvert structure constitutes swallow-tailed slot along the direction of the length of the aluminum tube. The left vertical surface and the right vertical surface of the prolate tube have the triangle slot structure which is indented. The bottom of the triangle slot is on the mean lines of the left vertical surface and the right vertical surface. The utility model adopts the swallow-tailed structure to realize the connection between the aluminum tube and the heat sink. The aluminum tube of the PTC heater has solved the problems that the use of bond adhesive tape in existing technology can cause the ageing of the adhesive tape, and the poor function of bonding can cause the potential safety hazard.
Description
Technical field:
The utility model relates to a kind of aluminum pipe of ptc heater, and it belongs to the field of electric heating technology, particularly the ptc heater technical field.
Background technology:
In the conventional electric heating technical field, using the PTC element has been the trend in electric-heating technology field as heating source, and the fail safe of its use and the popularity of application have obtained the popular welcome of industry.In the prior art, the PTC element of ptc heater needs a spatial accommodation, and this space is an aluminum pipe normally, has also designed fin in the aluminum pipe periphery.Present employed aluminum pipe is a kind of aluminum pipe of prolate type, and four surfaces of its aluminum pipe all are smooth.The aluminum pipe radiator that fin normally utilizes traditional adhesive structure and aluminum pipe to be fixed into to be structure as a whole, effect is also different with useful life and the aluminum pipe radiator of this spline structure is owing to use the difference of adhesive glue.If adopt common bonded adhesives, it is aging fast, makes easily the division of aluminum pipe and adhesive tape to cause potential safety hazard.If use silica gel as bonded adhesives, though bonding and heat conductivility are effective, cost is than higher.
Summary of the invention:
The purpose of my energy utility model is to provide a kind of bonding adhesive tape of can avoiding using, and is simple in structure, the aluminum pipe of ptc heater safe in utilization.
The purpose of this utility model is achieved in that
A kind of aluminum pipe of ptc heater, it is a hollow prolate type aluminum pipe, it is characterized in that the edge along its length of the upper surface of described prolate type aluminum pipe and lower surface be provided with projection and aduncate in the kinking structure, formation is along the dovetail type slot of aluminum pipe length direction.
Left and right two vertical surfaces of described flat elongated tubes are the triangular groove structure of indent, and the bottom land of its triangular groove is on the center line on left and right vertical surface.
The structure of dovetail groove that adopted the utility model realizes being connected of aluminum pipe and fin, and the aluminum pipe of the ptc heater of this spline structure has been avoided using the bonding adhesive tape in the prior art and the adhesive tape that produces is aging, the defective of the existing hidden danger safe in utilization of adhesive property difference.
Description of drawings:
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model
Fig. 2 is the structural representation that the utility model combines with fin
Fig. 3 is the use structural representation of the utility model on ptc heater
Embodiment:
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is further detailed:
As shown in fig. 1, the utility model is a hollow prolate type aluminum pipe, in order to realize not using the purpose of adhesive tape bonding fin, the edge along its length of the upper surface 1 of described prolate type aluminum pipe and lower surface 2 be provided with projection and aduncate in the kinking structure, formation is along the dovetail type slot 3,4 of aluminum pipe length direction.Just can be used for inserting fin at the upper surface 1 of prolate type aluminum pipe and the dovetail type slot 3,4 of lower surface 2 like this.The structure that has had corresponding fin in the prior art, directly fin is plugged in the dovetail type slot, and the dovetail type slot is compressed, allow fin and aluminum pipe mechanical bond with mechanical system, can finish combining of fin 6 and aluminum pipe 9, as shown in Figure 2.In order to strengthen heat-conducting effect of the present utility model, left and right two vertical surfaces of described flat elongated tubes are the triangular groove structure of indent, and the bottom land 5 of its triangular groove is on the center line on left and right vertical surface.Can increase the surface area of aluminum pipe like this, also just mean the increase area of dissipation, improve the ptc heater radiating effect.
Fig. 3 is the use of the utility model on ptc heater.Adopt the aluminum pipe 9 of structure of the present utility model, directly fin 6 is inserted in the upper and lower surperficial dovetail type slot 3,4 of aluminum pipe, PTC element group is same as the prior art, places aluminum pipe 9, according to prior art electrode 8 is set again, promptly constitutes ptc heater.This heater mainly connects radiator with the heater mechanical system, structural better.Because bond in order to guarantee structural behaviour with glue between radiator of the prior art and the aluminum pipe, the thermal conductivity of glue just can't improve, the product heat transfer efficiency will be affected.And can not consider the structural behaviour of glue when adopting the aluminum pipe of the utility model structure, and select the better heat-conducting cream of thermal conductivity, can significantly improve the thermal conductivity of product.
