Abstract
The utility model discloses a kind of aluminium alloy ratio-frequency welding that effectively can improve radiating efficiency and get pipe ready, it is formed primarily of body, this body entirety is in flat, the body that this is flat has made point-like pit, the utility model advantage is: by making on surface, existing smooth body one or both sides the point-like pit caved inward, these point-like pits can form equally distributed projection inside body, when cooling fluid is at Bottomhole pressure, not only can increase the contact area of cooling fluid and inboard wall of tube body, but also cooling fluid can be made in pipe to form eddy current and turbulent flow, extend the time of staying of cooling fluid in pipe, thus add the heat exchange performance of body, improve the heat exchanger effectiveness of body, structure is very simple.
Description
Technical field
The utility model relates to the technical field of heat exchanger component, more particularly relates to the technical field of heat exchanger ratio-frequency welded tube.
Background technology
Ratio-frequency welded tube is one of core component of heat exchanger system product, and heat exchanger can be widely used in aviation, electric power, industry and civil air conditioner, chemical industry, boats and ships, automobile, locomotive, traffic, machinery and the industry such as metallurgical.The quality of ratio-frequency welded tube quality directly has influence on the heat exchange performance of heat exchanger, at present, high performance ratio-frequency welded tube adopts the manufacture of covering grass plantation material to form mostly, and it has good heat exchange performance, the advantages such as intensity is high and lightweight, adopt by vast heat exchanger producer.But covering grass plantation ratio-frequency welded tube inner wall smooth sold in the market, the cooling fluid of heat exchanger is when Bottomhole pressure, and with the contact area of inside pipe wall is little and the time is shorter, heat exchange performance is still very good not.
Utility model content
The purpose of this utility model is exactly provide a kind of structure simply to solve above-mentioned deficiency, and the very good aluminium alloy ratio-frequency welding that effectively can improve radiating efficiency of heat exchange performance gets pipe ready.
The technical solution that the utility model adopts to solve the problems of the technologies described above is as follows:
The aluminium alloy ratio-frequency welding that effectively can improve radiating efficiency gets pipe ready, and it is formed primarily of body, and this body entirety, in flat, the body that this is flat has made point-like pit.
Described point-like pit distribution is in the both sides in flat body.
Described point-like pit is positioned at the medium position of body, 5 to 20 millimeters, the two ends of point-like pit distance body.
Described point-like pit is evenly distributed in rectangular on body.
The symmetrical inclined arrangement of the described point-like pit in flat body both sides.
The described point-like pit dislocation inclined arrangement in flat body both sides.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: by making on surface, existing smooth body one or both sides the point-like pit caved inward, these point-like pits can form equally distributed projection inside body, when cooling fluid is at Bottomhole pressure, not only can increase the contact area of cooling fluid and inboard wall of tube body, but also cooling fluid can be made in pipe to form eddy current and turbulent flow, extend the time of staying of cooling fluid in pipe, thus add the heat exchange performance of body, improve the heat exchanger effectiveness of body, structure is very simple.

Detailed description of the invention
By Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, the aluminium alloy ratio-frequency welding that effectively can improve radiating efficiency gets pipe ready, it is formed primarily of body 1, this body 1 entirety is in flat, body 1 one or both sides being flat at this make the point-like pit 2 evenly distributed in rectangular on the surface, conveniently ratio-frequency welding is got ready pipe when forming heat exchanger together with other assembly seam, there will not be the phenomenons such as dew weldering at bonding point, described point-like pit 2 is distributed in the medium position of body 1, point-like pit 2 is advisable apart from 5 to 20 millimeters, the two ends of body 1, namely the both ends of body 1 are being positioned at without point-like pit 2, it is still existing smooth structure, when all having made point-like pit 2 in body 1 both sides in flat, the point-like pit 2 of both sides can symmetrically arrange by inclined, also can in the arrangement of dislocation inclined.
