Abstract
The utility model relates to a flat solar heat absorption fin, which has a simple process, short labor hour and low cost. The flat solar heat absorption fin comprises fins; the middle parts of the fins are provided with circular holes; metal tubes are arranged in the circular holes; and the fins and the metal tubes are in expanded joint. Relative to the traditional ultrasonic welding process, a heat absorption body is made into a whole under the combined action of packing, extrusion, plastic deformation, blocking and the like, therefore, tube sheets can be totally fit in the axial direction and the radial direction. The contact area of copper tubes and the fins is increased by the process and is several ten times and even several hundred times of the contact area increased by the traditional welding process. The process has short labor hour and low cost and is free of troubles, i.e. the process has the advantage of achieving the greater, faster, better and more economical results and the like.
Description
Technical field
The utility model relates to a kind of panel solar heat absorption fin.
Background technology
At present both at home and abroad, mainly be to adopt the supersonic welding connection technology on the connected mode of fin and copper pipe, copper pipe in the one side welding of non-rete on whole plate or the band, copper pipe is that wire or point-like combine with whole plate of heat absorption or band, adopts this connected mode, realizes than being easier to, technology is ripe, but the contact area of this connected mode copper pipe and fin is less, is unfavorable for the conduction of heat on the fin, thereby influences the thermal efficiency of whole heat collector.
The utility model content
The purpose of this utility model provides a kind of technology simple exactly for addressing the above problem, and man-hour is few, the panel solar heat absorption fin that cost is low.
For achieving the above object, the utility model adopts following technical scheme:
A kind of panel solar heat absorption fin, it comprises fin, the fin middle part is provided with circular hole, metal tube is installed, fin and metal tube expanded joint in circular hole.
Described fin one side has chimb, and opposite side is provided with groove.
Elder generation penetrated into the copper pipe of well cutting in the pore of fin when the utility model was made, and fin was placed in the anchor clamps of electric tube expander again, and the bloated head of expander roll is put into the copper pipe that penetrates fin; Utilize the effect of the hydraulic press of electric tube expander, the headband that expands the end to end of expander roll from fin, makes the diameter expansion of copper pipe, thereby with copper pipe and the complete expanded joint of fin together.
Advantage of the present utility model: with respect to traditional ultrasonic welding process, absorber is to become one under the comprehensive functions such as parcel, extruding, flow, engaging, so axially, radially tube sheet can both coincide comprehensively, this technology has increased the contact area of copper pipe and fin, be tens of times of traditional welding technology so that hundreds of times, man-hour is few, and cost is low, be without fear of an attack from the rear, we can say that this technology has advantages such as many, fast, good, province.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the fin structure schematic diagram.
Wherein, 1. fin, 2. copper pipe, 3. chimb, 4. groove.
The specific embodiment
