Abstract
The utility model discloses a low cost integral pipe plate type heat-exchanging unit, being formed by processing the metal strips one time. The middle part is provided with pipes, both sides are provided with fins and the seams at the middle part can either be welded or mechanically meshed. The heat-exchanging unit is simple in molding process, material saving and easy to produce in batches with low cost and high efficiency, being suitable for the low pressure pipe plate type heat-exchanging system, especially for the field of solar energy water heater.
Description
It is relevant with heat exchanger technology to the invention belongs to field of solar collectors ， And.
In solar energy and air-conditioning technical field, widely applying the tube-sheet type heat exchanger fin.Have as the thermal-arrest purpose, as solar water heater.The conduct heat radiation purpose that has is as cooler.Used so far tube-sheet type heat exchanger fin, generally make of following several technologies: 1. shaping pipe and plate are welded as a whole.This technology weld seam is on the position of tube sheet combination, and is general in the bottom of plate, therefore welds inconvenience and complex process.2. shaping pipe and plate mechanical bond are one.This technology generally has between the plate pipe big in conjunction with thermal resistance, and the thermal efficiency hangs down problem.Therefore above-mentioned two kinds of technologies are subjected to the restriction of tubing specification and length because of adopting shaping pipe, and cost height, especially light-wall pipe heat exchanger fin, and the cost problem is more outstanding.3. integrated pipe plate structure will be managed and plate is extruded as the aluminium canalis pterygoideus of moulding etc. simultaneously with extruder.This technology needs dedicated extruded equipment, and the equipment installed capacity is big, and the one-time investment height is difficult for medium and small factory and adopts.
The present invention is directed to the problems referred to above and improve, proposed a kind of global formation that is easy to produce in batches and jointed tube-sheet type heat exchanger fin.
Main points of the present invention are: the heat exchanger fin sheet metal strip of certain width, and the middle part is shaped to pipe (2), and the pipe both sides are fin (1), and there is seam (3) centre.Center-line joint can be with bonding, available ratio-frequency welding, available Laser Welding, soldering, soldering or the like mode.Also can use the mechanical system interlock.The material of plate can be used steel, as steel plate, and galvanized sheet, available aluminium such as rustproof aluminum alloy, available copper or its alloy are made, and the cross section of pipe can be designed to arbitrary shape as required, and the moulding of pipe and welding can solve with general traditional handicraft method.
Heat exchanger fin of the present invention, owing to weld or interlock after adopting global formation, making tube sheet is one, only there is open seam together the centre, and is therefore little in conjunction with thermal resistance, the heat transfer efficiency height.Plate pipe one-shot forming simultaneously is convenient, and processing technology is simple, the material saving, and low being easy to of cost produced in batches.Above-mentioned good effect is that prior art is incomparable.
Drawings and Examples:
Accompanying drawing 1 is the heat exchanger fin schematic diagram, and 1 is fin; 2 are pipe; 3 is seam.
Accompanying drawing 2 is two kinds of heat exchanger fin schematic cross-sections, and 4 is seam to be welded.
Embodiment:
The solar water heater made from heat exchanger fin of the present invention as shown in Figure 3, the effective 0.25mm copper strips of plate, middle moulding φ 12mm left and right sides pipe, weld seam is the side center onboard, seam can form with high-frequency welding.Plate length and quantity can be determined as required.Parent tube and heat exchanger fin welding up and down.Present embodiment is owing to welding suitable batch production after the one-shot forming of plate pipe, so cost descends greatly.Simultaneously little in conjunction with thermal resistance, heat transfer efficiency improves greatly.
Claims (2)
1, a kind of tube-sheet type heat exchanger fin, the monoblock type heat exchanger fin that it is characterized in that having middle seam.
2, heat exchanger fin as claimed in claim 1, but it is characterized in that its tube section arbitrary shape.
