Abstract
The utility model discloses an internal thread connector of a heat exchanger, which comprises a heat exchanger body, wherein the heat exchanger body is formed by winding a seamless steel pipe, internal threads are arranged on the inner end surfaces of two ports of the seamless steel pipe, reinforcing pipes are sleeved on the outer walls of two ends of the seamless steel pipe, and the reinforcing pipes are in interference fit with the seamless steel pipe. The utility model can avoid welding the inner wire joint of the heat exchanger, and reduce the defects of welding seam leakage and the like caused by welding.
Description
Technical Field
The utility model relates to an internal thread joint of a heat exchanger.
Background
When a certain heat exchanger of the company is produced, the heat exchanger is wound, then an inner wire joint of the heat exchanger is welded, and the thickness of a welding joint is controlled within the assembly requirement range because of thinner welding joints, and the welding joints are easy to leak and break.
Disclosure of Invention
The utility model provides an internal thread joint of a heat exchanger for solving the problems existing in the prior art.
The utility model adopts the technical scheme that:
the utility model provides a heat exchanger internal thread connects, includes the heat exchanger body, the heat exchanger body is formed by seamless steel pipe coiling, and the interior terminal surface of seamless steel pipe's both ends mouth is equipped with the internal thread, overlaps on the outer wall at seamless steel pipe's both ends and establishes the strengthening pipe, interference fit between strengthening pipe and the seamless steel pipe.
Further, two ports at the tail end of the seamless steel pipe are of a port structure which is formed by shrinking through pipe shrinking machine processing, the reinforcing pipe is sleeved on the outer wall of the shrinking port, and the outer wall surface of the reinforcing pipe is flush with the outer wall surface of the heat exchanger body.
The utility model has the following beneficial effects:
the utility model can avoid welding the inner wire joint of the heat exchanger, and reduce the defects of welding seam leakage and the like caused by welding.
Drawings
Fig. 1 is a structural diagram of the present utility model.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, the heat exchanger internal thread connector comprises a heat exchanger body 1, wherein the heat exchanger body 1 is formed by winding a seamless steel pipe, two ports at the tail end of the seamless steel pipe are of a inwards shrinking port structure formed by processing a shrinking machine, a reinforcing pipe 11 is sleeved on the outer wall of the inwards shrinking port, the outer wall surface of the reinforcing pipe 11 is flush with the outer wall surface of the heat exchanger body 1, and the reinforcing pipe 11 is in interference fit with the seamless steel pipe. The reinforcing pipe 11 ensures the strength of the two end ports of the seamless steel pipe, and the inner end surfaces of the two end ports of the seamless steel pipe are provided with internal threads. The utility model can avoid welding the inner wire joint of the heat exchanger, and reduce the defects of welding seam leakage and the like caused by welding.
The foregoing is merely a preferred embodiment of the utility model, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the utility model, which modifications would also be considered to be within the scope of the utility model.
