CN2062804U - Continuously riveted core sheet of solar energy water heater - Google Patents

Abstract

The utility model relates to a heat absorbing core sheet of a solar energy water heater, which is composed of metal thin boards and circular tubes. The core sheet is packed between two thin boards pressed with an omega-shaped groove by the circular tube. The two thin boards and the circular tube are continuously riveted into integral structure at the both sides of the groove. The core sheet has compact combination of the circular tubes and the thin boards and high performance of heat exchanging.

Description

Continuously riveted core sheet of solar energy water heater

The utility model relates to a kind of solar water heater heat absorption chip that sheet metal and pipe are linked into an integrated entity with continuous clinching method.Belong to the machining product.

Plate, pipe are linked into an integrated entity, as solar water heater heat absorption chip, prior art be tie up, bonding, welding and extruding inflation.Tie up the chip exposure level and do not have guarantee, now superseded substantially, between adhering chip plate, pipe binding agent is arranged, thermal resistance is big, easily aging, and applicability is very little, welding core bar presentation quality is poor, it is bad that weld seam bears the empty performance of shining, and just can't adopt when being different materials at plate, pipe, and extruding inflation core bar needs the complicated pretreatment process and the line that forms a complete production network, use strict coil pipe and the roll bending of material, general condition can't be used.

The purpose of this utility model is at above-mentioned shortcoming, the chip that the effective continuous riveted joint mode of metallic plate is closely linked into an integrated entity.

The utility model is that pipe wraps between two thin plates that are pressed with Ω shape groove, the structure that two thin plates and pipe is riveted into one continuously at groove two side positions, different as requested, plate, pipe can be same material, also can be unlike material, caliber, wall thickness, thickness of slab and plate, length of tube can change as requested, and the riveting point spacing is 1-10cm.Adopt solar water heater of the present utility model heat absorption chip, outward appearance is clean and tidy, and plate, pipe jointing are tight, functional.

Below in conjunction with description of drawings embodiment of the present utility model.Fig. 1 is the specification digest accompanying drawing.

Fig. 1 is embodiment 1.

Among the figure

1, auxilliary plate 2, fin plate

3, pipe 4, riveting point

The plate pipe jointing shape facility of Fig. 1 chip is that the riveting point of auxilliary plate and fin plate is the reducing recess.

Fig. 2 is embodiment 2.

1, auxilliary plate 2, fin plate

3, pipe 4, riveting point

The plate pipe jointing shape facility of Fig. 2 chip is that the riveting point of auxilliary plate and fin plate is the flange hole that two-layer thin plate all penetrates.

Claims (2)

1, a kind of solar water heater heat absorption chip is characterized in that metal circular tube is wrapped between two thin plates that are pressed with Ω shape groove, in the groove both sides with two thin plates continuously riveted joint pipe and the thin plate of making fin are closely linked together.

2, heat absorption chip according to claim 1 is characterized in that continuous riveting point is the reducing recess or is the flange hole that two thin plates all penetrate between two thin plates.The riveting point spacing is 1-10cm.
