Description
Technical field
The utility model relates to a kind of radiator, especially relates to the assembling mode of a kind of cold-hot impact structure backplate and mainboard.
Background technology
Car radiator core used at present, due to its guard board structure, cannot in use adapt to region, environment change and cause temperature jump.North latitude 3o ~ 53o is crossed in China territory, and China's the Northeast's winter temperature reaches subzero 20 ~ 30 DEG C, and radiator internal-external temperature difference reaches 100 DEG C, causes radiator core body short for service life, and vibration resistance, cold-hot impact property are poor.Due to backplate, can not to absorb or discharge core body in time inner due to vibration, thermal shock and the internal stress that produces, thus cause whole radiator to lose efficacy, and causes automobile engine normally to work.
Summary of the invention
The purpose of this utility model is: provide one can absorb or discharge core body internal stress in time, the assembly structure of the cold-hot impact structure backplate that vibration resistance, cold-hot impact property are good and mainboard.
The technical solution of the utility model is: the assembling mode of cold-hot impact structure backplate and mainboard, the mainboard comprising backplate and coordinate with it, respectively there are two right-angle structures of a continuous right-angle bending at backplate two ends, two right-angle structure is made up of the first right angle, the second right angle, the first plane, short plane and panel reality, the first right angle is formed between first plane and short plane, form the second right angle between short plane and panel reality, the first plane is provided with at least one breach coordinated with mainboard; Two right-angle structure of backplate and the end of mainboard fit together, and the first plane is close to the contact of mainboard outerplanar forming surface, has gap between short plane and mainboard lower plane.
Further, short plane is parallel with mainboard lower plane, and the gap between short plane and mainboard lower plane is 2mm ± 1mm.
Further, panel reality is provided with the flange of 10 ~ 20mm, and the end of panel reality is respectively provided with a pressure tongue.
Further, pressure tongue and panel reality are 10o angle, and pressure tongue end is concordant with short plane.
Further, the one or more breach coordinated with mainboard in backplate first plane are symmetrical about center of protecting panel's line.
The beneficial effects of the utility model are: the utility model is two right-angle structure because backplate two ends adopt, two right-angle structure of backplate and the end of mainboard fit together, short plane between right angle, backplate end two and the lower plane of mainboard are provided with the gap of 2mm ± 1mm, backplate defines buffering area, the deformation that core body produces due to temperature abrupt change can be cushioned, absorb in time or release core body internal stress.It is simple that the utility model has structure, and the advantages such as vibration resistance, cold-hot impact property are good, are applied to long service life on radiator core body, can make extend more than 50% the service life of heat radiator assembly.

Detailed description of the invention
As can be seen from the schematic diagram of structural representation of the present utility model shown in Fig. 1, the two right-angle structure in Fig. 2 backplate end, the mainboard 200 that the utility model comprises backplate and coordinates with it, respectively there are two right-angle structures 100 of a continuous right-angle bending at backplate two ends.Two right-angle structure 100 is made up of the first right angle 102, first, right angle 101, second plane 103, short plane 104 and panel reality 109, the first right angle 101 is formed between first plane 103 and short plane 104, the second right angle 102 is formed between short plane 104 and panel reality 109, first, second right angle is through arc transition, and the R at the first right angle 102 place, right angle 101, second is not more than 3mm.As shown in the top view of Fig. 3, backplate first plane 103 is provided with at least one breach 105 coordinated with mainboard 200, be two breach 105 in Fig. 3, the breach 105 that the one or more and mainboard 200 in backplate first plane 103 coordinates is all symmetrical about center of protecting panel's line 116.
As shown in Figure 1, backplate wherein two right-angle structures 100 of one end and the end of mainboard 200 fits together, and the first plane 103 is close to the contact of mainboard outerplanar 201 forming surface, adds the area of welding, thus strengthens the stability of connection, improves weld strength.Short plane 104 is parallel with mainboard lower plane 202, gap 300 between short plane 104 and mainboard lower plane 202 is 2mm ± 1mm, two right-angle structure 100 and gap 300 can effectively absorptive core due to the timely release of high temperature suddenly, distortion that quenching produces and stress, backplate defines buffering area, the deformation that core body produces due to temperature abrupt change can be cushioned, timely absorption or release core body internal stress, reduce stress to the damage of mainboard, radiating tube, improve the service life of radiator.For the radiator that 800mm core is high, its linear change is 2mm, and the gap 300 between the short plane 104 of backplate and mainboard lower plane 202 is set to 2mm; When core body height is more than 800mm, the gap between the short plane 104 of backplate and mainboard lower plane 202 suitably can be increased.The both sides of panel reality 109 are respectively provided with the flange 114 of 10 ~ 20mm, and the end of panel reality 109 is respectively provided with an intilted pressure tongue 115, and pressure tongue 115 is 10o with the angle ɑ of panel reality 109, and pressure tongue 115 end is concordant with short plane 104.The Main Function of pressure tongue 115 is: 1, press tongue 115 end to push down the end of sideband, make sideband end and other heat-radiation belt end be in same position; 2, apply certain pressure to sideband end, heat-radiation belt end and radiating tube are closely cooperated, to improve weld strength, strengthen the support force to radiating tube, can the stress that produces of transmitting vibrations effectively, to reduce vibration to the damage of radiating tube, improve service life of radiator.
