Abstract
The invention discloses a connection positioning structure of an adapter and a collecting pipe. The connection positioning structure comprises the adapter and the collecting pipe, a connection surface which is matched with the outer wall of the collecting pipe is arranged on the adapter, and a positioning protruding portion and a positioning groove which are matched with each other are arranged on the connection surface and the outer wall of the collecting pipe. According to the connection positioning structure, argon arc welding positioning is not used so that problems that overlaps exist at positioning positions and product appearances are not attractive due to the fact that adapters and collecting pipes are positioned through argon arc spot welding in prior art are solved, the positioning is accurate and reliable, and working environments of workers are improved.
Description
Technical field
The present invention relates to field of heat exchangers, particularly the location structure that is connected of a kind of adapter and header.
Background technology
In the existing micro-channel heat exchanger, be welded with two kinds of methods between tube connector and the header, the one, tube connector directly is welded on the hole of header, adopt the Manual flame brazing mode, because collecting pipe material itself is thinner, burning appears in this a kind of method easily, and burning place burst pressure does not very easily reach requirement; The 2nd, tube connector directly is not welded on the header, come transition to connect by adapter: at first with behind adapter and the header employing argon arc spot welding location, then adapter and header enter NB soldering oven NB weldering, after the NB soldering, tube connector are inserted in the hole of adapter again, adopt the outer gas brazing of NB soldering oven, this method is owing to adopted adapter, and general adapter material is very thick, even the welding burning, burning place burst pressure still can reach requirement, has avoided the shortcoming of method one.But method two has a remarkable shortcoming: owing to adopt the argon arc spot welding location, there is overlap at the place, location, and product appearance is bad; In addition, argon welding needs high-temperature operation, and is very large to workman's physical effects.
Summary of the invention
The object of the invention just provides the location structure that is connected of a kind of adapter and header, do not adopt the argon arc welding location, solve in the prior art adapter and header and be positioned at the location problem such as locate overlap is arranged, product appearance is bad by argon arc spot welding, registration is reliable, improves workman's working environment.
The present invention adopts following technical scheme: the location structure that is connected of a kind of adapter and header, comprise adapter and header, described adapter is provided with the joint face that cooperates with the outer wall of header, and the outer wall of described joint face and header is provided with positioning convex and the locating slot that cooperatively interacts.
Further, be provided with the switching hole that header is communicated with tube connector in the described adapter, the tube wall of described header is provided with the afflux pore with the corresponding connection in the hole of transferring, described positioning convex is located on the described joint face and is positioned at the edge in switching hole, and described locating slot is located on the outer wall of described header and is positioned at the edge of afflux pore.
Further, described positioning convex arranges and is distributed on the edge in switching hole in pairs.Be convenient to processing, it is stable to connect location structure.
Further, the face at that sidewall place in close switching hole overlaps with the face at the hole wall place in described switching hole on the described positioning convex.Be convenient to processing.
Further, be provided with the first solder side between the hole wall in that sidewall in close switching hole and described switching hole on the described positioning convex.Participate in welding, improve bonding strength and sealing.
Further, the face at that sidewall place away from the switching hole overlaps with the face at the sidewall place of described adapter on the described positioning convex.Be convenient to processing.
Further, be provided with the second solder side between the sidewall away from switching that sidewall in hole and described adapter on the described positioning convex.Participate in welding, improve bonding strength and sealing.
Further, described locating slot is open slot or through hole.Open slot is convenient to production and processing, reduces simultaneously contact-making surface, is convenient to sealing, and namely the open side of locating slot does not need to consider sealing again.
Further, be positioned at the end surface side of locating slot on the inwall of described header along being provided with in-flanges.Turnup structure has increased the contact area of locating slot and positioning convex, is conducive to increase weld strength, strengthens the stability of location structure.
Further, be positioned at the end surface side of locating slot on the outer wall of described header along being provided with flanging, described joint face is provided with the groove with described flanging corresponding matching.Further guarantee precise and stable location.
After adopting technique scheme, the present invention has following advantage: realize the location by frame for movement, registration is reliable, need not adopt the argon arc welding location, does not just have the problem that occurs because of argon arc welding, also can greatly improve workman's working environment simultaneously.
