Abstract
The utility model relates to an expansion bar for fixing and connecting a condensing tube and a radiating fin, which comprises the expansion bar. The utility model is characterized in that the outer wall of the expansion bar has the same shape with the inner wall of the abnormal condensing tube. A gap exists between the outer wall of the expansion bar and the inner wall of the abnormal condensing tube, and the brink at the head part of the expansion bar is provided with an expansion joint. The maximum cross section of the expansion joint is larger than the cross section of the inner wall of the abnormal condensing tube. The expansion joint is formed by three sections of circular arc surfaces, and the three sections of circular arc surfaces are smoothly connected with each other. The first section circular arc surface and the front end face of the expansion bar have a round angle transitional connection, and the end section circular arc surface is smoothly connected with a bar body of the expansion bar. The utility model has the advantage of tightly fixing and connecting the abnormal condensing tube and the thin and soft radiating fin.
Description
Technical field
The utility model relates to a kind of bloated rod, particularly a kind ofly is used for the bloated rod that condenser pipe is fixedlyed connected with radiating fin.
Background technology
Now in order to improve the efficient of heat exchange, develop condenser with special-shaped condenser pipe, in order to carry out the assembling of condenser, usually the radiating fin on the condenser is because relatively thinner, soft, its through hole of wearing condenser pipe is usually slightly larger than the diameter of condenser pipe, so be convenient to the smooth assembling on production line, but for heat and extraneous exchange with the medium in the condenser pipe, condenser pipe must be closely with being connected of radiating fin, if therefore adopt scolder to weld, just may cause rosin joint, the leakage weldering of product, thereby influence the quality of condenser.
Summary of the invention
The purpose of this utility model is to solve the condenser that has special-shaped condenser pipe in the prior art to solve existing above-mentioned problem in being connected of condenser pipe and radiating fin, provide a kind of can be with special-shaped condenser pipe and the bloated rod that approaches, soft radiating fin closely is fixedly coupled.The utility model designs a kind of bloated rod that condenser pipe is fixedlyed connected with radiating fin that is used for, comprise the rod that expands, it is characterized in that: the outer wall of the rod that expands is identical with the inner wall shape of special-shaped condenser pipe, between the outer wall of bloated rod and the inwall of special-shaped condenser pipe the slit is arranged, the rod that expands the avris of head expansion joint is arranged, the maximum cross section of expansion joint is greater than the cross section of the inwall of special-shaped condenser pipe.Expansion joint is that three sections arc surfaces constitute, smooth connection between three sections arc surfaces, between the front end face of first section arc surface and the rod that expands for round-corner transition is connected, latter end arc surface and bloated excellent smooth connection of barred body.The utility model has the advantages that and special-shaped condenser pipe closely can be fixedlyed connected with thin, soft radiating fin.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise the rod 1 that expands among the figure, it is characterized in that: the outer wall of the rod 1 that expands is identical with the inner wall shape of special-shaped condenser pipe, between the outer wall of bloated rod 1 and the inwall of special-shaped condenser pipe the slit is arranged, the rod 1 that expands the avris of head expansion joint 2 is arranged, the maximum cross section of expansion joint 2 is greater than the cross section of the inwall of special-shaped condenser pipe.Expansion joint 2 is made of arc surface 3, arc surface 4,5 three sections arc surfaces of arc surface, smooth connection between arc surface 3, arc surface 4, the arc surface 5, is connected latter end arc surface 5 and bloated excellent 1 smooth connection of barred body for fillet 6 transition between the front end face of first section arc surface 3 and the rod 1 that expands.In the practicality on assembly line special-shaped condenser pipe be inserted into when not welding as yet behind the radiating fin, this moment, special-shaped condenser pipe was shape in upright arrangement, the some rods 1 that expand are installed on the press, press is depressed after aiming at special-shaped condenser pipe, the rod 1 that expands enters in the special-shaped condenser pipe, with fastening with radiating fin behind special-shaped condenser pipe distending one ringlet.
Claims (2)
1, a kind ofly is used for the bloated rod that condenser pipe is fixedlyed connected with radiating fin, comprise the rod that expands, it is characterized in that: the outer wall of the rod that expands is identical with the inner wall shape of special-shaped condenser pipe, between the outer wall of bloated rod and the inwall of special-shaped condenser pipe the slit is arranged, the rod that expands the avris of head expansion joint is arranged, the maximum cross section of expansion joint is greater than the cross section of the inwall of special-shaped condenser pipe.
2, by the described a kind of bloated rod that condenser pipe is fixedlyed connected with radiating fin that is used for of claim 1, it is characterized in that: expansion joint is that three sections arc surfaces constitute, smooth connection between three sections arc surfaces, between the front end face of first section arc surface and the rod that expands for round-corner transition is connected, latter end arc surface and bloated excellent smooth connection of barred body.
