Abstract
The utility model discloses a collecting pipe and a condenser including the same; the cross section of the collecting pipe possesses anti-rotating planes and two installation convex tongues of a connection block; the connection block is installed between the two convex tongues of the collecting pipe and is in contact with the installation plane of the collecting pipe; the installation convex tongues of the connection block possess local compressive deformation, through which the collecting pipe and the connection block are in interference fit connection. The collecting pipe is provided with a position-restricted projection; the anti-rotating planes of the collecting pipe can avoid the collecting pipe from rotating around one axis as much as possible; through the local compressive deformation of the contact parts of the collecting pipe and the connection block, the collecting pipe and the connection block are fixed through interference fit, and thereby argon arc welding processes are canceled and the connection block to be welded can be avoided from deformation aggravation with the rotating of the collecting pipe. The position-restricted projection can restrict the inserting size of a flat tube to the collecting pipe. The advantages are that the installation positions of the collecting pipe and the connection block are accurate and have with no deflect; core bodies with no solder joints have good appearance quality; manufacturing operation is simplified and cost is saved.
Description
Technical field
The utility model belongs to the vehicle air conditioning technical field, relates to a kind of header and comprises the condenser of this header.
Background technology
The header of existing condenser is generally tubular structure, when the many and weight of the coupling block quantity on the header is big, coupling block takes place with together deflection of header through regular meeting, finally causes the coupling block dimension overproof; Existing condenser generally all will be welded on contiguous block on the header by the mode of argon arc welding welding, in the process of welding, can aggravate the together deflection of coupling block with header; And the solder joint of argon arc welding is bigger, and after the welding of NB stove, solder joint can't be eliminated, the core body presentation quality after the influence welding; The header of tubular structure does not have flat tube position limiting structure, and the size that flat tube inserts in the header is inconsistent.
Summary of the invention
The utility model discloses a kind of header and comprises the condenser of this header, inserts problems such as size in the header is inconsistent to solve coupling block in the prior art with can't eliminate the effects of the act welding back core body presentation quality, flat tube of together deflection of header, solder joint.
The utility model is characterized in that: the header cross section has the anti-rotation plane and two coupling blocks are installed protruding tongue; Coupling block is installed between two protruding tongues of installation of header, and coupling block contacts with the header mounting plane; Coupling block is installed protruding tongue and is had local crimp, and header is connected with the local crimp interference fit that coupling block is installed protruding tongue by coupling block.Header anti-rotation plane can avoid header to rotate around a certain axis as far as possible; By header and the local deformation of coupling block contact site, interference fit is fixed the two, and the cancellation argon arc welding technique avoids welding the rotation deformed of coupling block with header.
The utility model is characterized in that the header place has increased and has spacing preiection, and spacing preiection restriction flat tube inserts the size in the header.
Good effect of the present utility model is: the header cross section has the anti-rotation plane and two coupling blocks are installed protruding tongue, and coupling block and header installation site are accurate, zero deflection; No solder joint core body presentation quality is good; Simplify manufacturing process, save cost.
