Description
Technical field
The present invention relates to automobile radiators accessory technical field, specifically a kind of backplate expansion joint anti-drop device and dissipate
Hot device core.
Background technology
The function of automobile cooling system is automobile is maintained under all operating modes within the scope of appropriate temperature.Automobile
Cooling system have air-cooled point with water cooling.It is known as air cooling system using air as cooling medium, using coolant as cooling medium
Be known as water-cooling system.Usual water-cooling system is by water pump, radiator, cooling fan, thermostat, compensation bucket, engine body
And the composition such as water jacket in cylinder cover and other auxiliary equipments.Wherein, radiator is responsible for the cooling of recirculated water, radiator
Water pipe and heat sink use aluminium and are made, and aluminum water pipe makes flat pattern, and heat-radiation belt corrugated, focuses on heat dissipation performance, installation
Accomplish that windage is small as far as possible, cooling effectiveness will height perpendicular to the direction of air flow in direction.Coolant flows in radiator core body
Dynamic, air passes through in vitro in radiator core.The coolant of heat radiates and turns cold to air, and cold air then dissipates because absorbing coolant
The heat that goes out and heat up, so radiator is a heat exchanger.
Traditional heat sinks backplate expansion joint and heat-radiation belt junction in brazing process because contact surface is smaller and unbalance stress,
Easily there is the problem of de- band, therefore, how to ensure effectively contacting between backplate and heat-radiation belt, the heat dissipation for ensureing radiator
Ability, stablizes vehicle work, is the problem of those skilled in the art are in the urgent need to address.
The content of the invention
The technical assignment of the present invention is the deficiency for more than, there is provided a kind of backplate expansion joint anti-drop device and radiator core
Body, can solve the backplate expansion joint of radiator in the prior art with the brazing process of heat-radiation belt junction since contact surface is smaller
And unbalance stress easily causes the problem of de- band.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of backplate expansion joint anti-drop device, including backplate, the both ends of backplate are each provided with a salient point, and are set with backplate plate
There is expansion joint, expansion joint both sides are symmetrically arranged with multiple salient points.
Expansion joint is arranged at the 1/3 of backplate plate body.
Distance of each salient point of expansion joint both sides apart from expansion joint center is 8mm.
The quantity of salient point is 2~8, and salient point length is 9.5mm, is highly 0.5mm.
Radiator core body, including heat-radiation belt and heat-dissipating pipe, the backplate of radiator core body is equipped with expansion joint anti-drop device, swollen
Swollen section anti-drop device is any backplate expansion joint anti-drop device in above-mentioned, and heat-radiation belt is arranged between backplate and heat-dissipating pipe,
And the salient point on backplate is engaged with heat-radiation belt and is connected.
Compared to the prior art a kind of the backplate expansion joint anti-drop device and radiator core body of the present invention, has beneficial below
Effect：
1st, expansion joint both sides are symmetrically arranged with salient point, and each distance of the salient point apart from expansion joint center is 8mm, salient point length
It is highly 0.5mm for 9.5mm, the salient point by increasing above-mentioned size can ensure the tight fit of heat-radiation belt and backplate；
2nd, by increasing salient point at backplate expansion joint, ensureing that heat-radiation belt and backplate are close-fitting meanwhile, it is capable to prevent pricker
The problem of heat-radiation belt sideband comes off and causes radiator poor appearance during weldering, performance is bad；
3rd, apparatus structure design advantages of simple, dependable performance, can effectively prevent backplate expansion joint and heat-radiation belt junction
Because contact area is small, occur the problem of traction in brazing process, the arrangement increases the aesthetics and performance of radiator,
Therefore, have good value for applications.
