Abstract
The utility model discloses a welding and positioning tool for a fin-free heat exchanger. The welding and positioning tool for the fin-free heat exchanger comprises a positioning rod, wherein more than one clamping groove group consisting of more than two clamping grooves are formed in the side surface of the positioning rod; the clamping grooves of the welding and positioning tool are used for clamping and placing flat tubes, and the clearance between every two clamping grooves is constant, so that the clamping grooves have a positioning effect on the flat tubes, and the flat tubes can be prevented from being deformed and stretched caused by the reasons of displacement and heat-expansion and cold-contraction in a welding process; therefore, the flat tubes are arranged uniformly, stress cannot be generated at the welding position, the welding is not easily influenced, the firmness of a welding seam is high, and the appearance of the welding seam is good.
Description
Technical field
The utility model relates to the welding positioning tool of non-finned heat exchanger.
Background technology
In order to realize the exchange of heat, heat exchanger has application in all trades and professions.Present most heat exchanger has fin, but is provided with after fin, and the volume of this heat exchanger is large, and therefore, the place little in space is inapplicable.
In order to reduce the volume of heat exchanger, there is the heat exchanger that fin is removed, as at application number being was to disclose a kind of muscle to top formula non-finned heat exchanger core body in the patent documentation on June 26th, 2,013 201320045331.8 Granted publication days, adopt said structure can reduce the volume of heat exchanger, can be widely used in the heat exchanger such as electronics, communication.But owing to there is no fin between flat tube, cannot support flat tube, and very little of spacing between flat tube, in brazing process, the impact of being expanded with heat and contract with cold, flat tube can produce distortion, junction between flat tube and body easily produces stress, thereby it is inhomogeneous to be very easy to cause flat tube in the heat exchanger after moulding to arrange, and the intensity of weld is low, and weld seam is not attractive in appearance.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of non-finned welding heat-exchanger positioning tool.
The technical scheme solving the problems of the technologies described above is: non-finned welding heat-exchanger positioning tool, comprise backstay, and on the side of backstay, be provided with the more than one group pocket set being formed by more than two draw-in groove.
Further, described backstay is hollow pipe, and draw-in groove communicates with in hollow pipe.
The beneficial effects of the utility model are: the draw-in groove of this welding positioning tool is for holding flat tube, and gap between draw-in groove is constant, like this, flat tube is had to positioning action, can prevent that flat tube from displacement and former thereby distortion, stretching because expanding with heat and contract with cold occurring in welding process, therefore, can make arranging evenly of flat tube, can not produce stress at weld, be not easy to impact welding, the fastness of weld seam is high, and the outward appearance of weld seam is good; In addition, owing to adopting hollow backstay, therefore, can make flat tube being heated evenly everywhere, can not cause easily deformable phenomenon because of the inequality of being heated.

Fig. 2 is the front view of welding positioning tool.
Fig. 3 is the left view of welding positioning tool.
Fig. 4 is the enlarged drawing of A in Fig. 1.
Fig. 5 is the structural representation of non-finned heat exchanger.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 5, non-finned interchanger comprises body 1 and is located at the flat tube 2 between two bodys 1, and the gap between adjacent flat tube is 2-3mm, is connected with pedestal 3 therein on a body, is connected with the inlet pipe 4 communicating with body and goes out pipe 5 on pedestal 3.
As shown in Figures 1 to 4, non-finned welding heat-exchanger positioning tool comprises backstay 6, backstay is square tube, and hollow-core construction, on the side of backstay, be provided with the more than one group pocket set being made up of more than two draw-in groove 7, in the present embodiment, pocket set is three groups, therefore, can while three heat exchangers of holding side by side.
The draw-in groove 7 of this welding positioning tool is for holding flat tube 2, and gap between draw-in groove 7 is constant, like this, flat tube is had to positioning action, can prevent that flat tube from displacement and former thereby distortion, stretching because expanding with heat and contract with cold occurring in welding process, therefore, can make arranging evenly of flat tube, can not produce stress at weld, be not easy to impact welding, the fastness of weld seam is high, and the outward appearance of weld seam is good; In addition, owing to adopting hollow backstay, therefore, can make flat tube being heated evenly everywhere, can not cause easily deformable phenomenon because of the inequality of being heated.
Claims (2)
1. non-finned welding heat-exchanger positioning tool, is characterized in that: comprise backstay, be provided with the more than one group pocket set being made up of more than two draw-in groove on the side of backstay.
