Description
Technical field
The present invention relates to a kind of automobile radiators, particularly a kind of tube-expanding type automobile radiators.
Background technology
Automobile radiators is in the market divided into tube-expanding type radiator and braze welding type radiator because mainboard is different from the connected mode of radiating tube.The advantage of tube-expanding type automobile radiators is that assembling mode is simple, low cost of manufacture, shortcoming is the restriction owing to being subject to existing expansion tube process technology, make the radiating tube of tube-expanding type automobile radiators that cross section can only be adopted to be circular circular radiating tube, although the swollen mouth ratio of circular radiating tube is easier to also can better ensure the quality of products, but circular radiating tube is because its adjacent center is apart from can be larger, make its layout quantity in radiator can be subject to strict restriction, thus cause the area of dissipation of whole radiator little, reduce the radiating efficiency of radiator.
The advantage of braze welding type radiator is that radiating effect is better, because it can adopt flat radiating tube instead of circular radiating tube, the adjacent center of flat radiating tube is less apart from meeting, its layout quantity in radiator can be increased, thus make the area of dissipation of whole radiator large, improve the radiating efficiency of radiator; Shortcoming is that assembling mode wants complicated, manufacturing cost is also high.In addition, the tube-expanding type radiator of prior art also has the following disadvantages: the connection namely between mainboard and circular radiating tube is not reliable especially, and the tube expanding joint position after expand tube easily gets loose because expanding with heat and contract with cold, and can not hydroecium be kept for a long time to seal.
Summary of the invention
In view of the deficiency of background technology, problem to be solved by this invention is to provide that a kind of radiating efficiency is higher, structure is simple, the bonding strength of mainboard and radiating tube is higher, the tube-expanding type automobile radiators of hydroecium better tightness.
The present invention implements by the following technical programs:
A kind of tube-expanding type automobile radiators, comprise left and right hydroecium and heat radiation core body, described heat radiation core body is made up of radiating tube and fin, described radiating tube is arranged in parallel, described fin is located in the middle of two adjacent radiating tubes, described left and right hydroecium has mainboard, mainboard is connected by expand tube mode with the mouth of pipe of radiating tube, described mainboard arranges expand tube hole, sealing ring is provided with between the outer wall of expand tube hole and the radiating tube mouth of pipe, it is characterized in that: the shape of cross section of described radiating tube is 8-shaped, the short transverse of 8-shaped is perpendicular to the length direction of mainboard.
The tube-expanding type automobile radiators of technique scheme, its key have employed the radiating tube that shape of cross section is 8-shaped, the profile of 8-shaped radiating tube is similar to the flat tube that soldering radiator uses, but area of dissipation is larger, and meeting adjacent center the same as flat tube is less apart from meeting when assembling, its layout quantity in radiator can be increased, thus the area of dissipation of whole radiator is increased, improve the radiating efficiency of radiator; Further, the mouth of pipe of 8-shaped radiating tube is equivalent to the superposition of two round mouths, and this structure more meets the expansion tube process requirement of pipe, easily carries out expand tube and indeformable, so adopt the pipe expansion tube process improved just can implement.
As preferably, the mouth of pipe of described radiating tube is made up of changeover portion, swelling section and turned welt section after expand tube, closely the sealing formed between the radiating tube mouth of pipe and mainboard is compressed between the isometrical expansion of caliber of swelling section and the endoporus of sealing ring, turned welt section is positioned at the outer end of swelling section in the mouth-shaped that turns up, and the inner that changeover portion is positioned at swelling section is cone shape.
Adopt after technique scheme, radiating tube expands to be formed with mainboard expand tube hole by the caliber of swelling section and coordinates, and make radiating tube be fixed on mainboard, sealing ring is pressed in formation between mainboard and radiating tube and seals; Changeover portion not only plays the transitional function that swollen mouth is slowly out of shape, and when making the water inflow and outflow radiating tube in hydroecium more smoothly; Turned welt section makes radiating tube not easily because expanding with heat and contract with cold from mainboard, radiating tube and mainboard higher, the hydroecium better tightness of bonding strength.
As preferably, the shape in described expand tube hole is 8-shaped, and the internal via shape of described sealing ring is also 8-shaped.
As preferably, described radiating tube is provided with two rows along mainboard short transverse.
