Description
Technical field
The utility model is related to automobile radiators accessory technical field, specifically a kind of backplate expansion joint anti-drop device
And radiator core body.
Background technology
The function of automobile cooling system is to make automobile that can be maintained under all operating modes within the scope of appropriate temperature.Automobile
Cooling system be divided into it is air-cooled with water cooling.It is cooling medium with coolant liquid with the referred to as air cooling system that air is 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 compositions 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 cooling fin are mostly used aluminium and are made, and aluminum water pipe makes flat pattern, and heat-radiation belt corrugated focuses on heat dissipation performance, installation
Direction accomplishes that windage is small as possible perpendicular to the direction that air flows, and cooling efficiency wants high.Coolant liquid flows in radiator core body
Dynamic, air passes through in vitro in radiator core.The coolant liquid of heat radiates to air and is turned cold, and cold air then dissipates because absorbing coolant liquid
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 taking off band, therefore, how to ensure effectively contacting between backplate and heat-radiation belt, for ensureing the heat dissipation of radiator
Ability stablizes vehicle work, is those skilled in the art's problem in the urgent need to address.
Invention content
The technical assignment of the utility model is to provide a kind of backplate expansion joint anti-drop device and radiator for above insufficient
Core, can solve the backplate expansion joint of radiator in the prior art in the brazing process of heat-radiation belt junction due to contact surface compared with
The problem of small and unbalance stress easily causes de- band.
Technical solution adopted by the utility model to solve its technical problems is：
The both ends of a kind of backplate expansion joint anti-drop device, including backplate, backplate are each provided with a salient point, and backplate plate body
It is equipped with 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.
The backplate of radiator core body, including heat-radiation belt and heat-dissipating pipe, radiator core body is equipped with expansion joint anti-drop device, swollen
Swollen section anti-drop device is that any backplate expansion joint anti-drop device, heat-radiation belt are arranged between backplate and heat-dissipating pipe among the above,
And the salient point on backplate is engaged with heat-radiation belt and connect.
Compared to the prior art a kind of backplate expansion joint anti-drop device and radiator core body of the utility model, have following
Advantageous effect：
1, 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 is 9.5mm, is highly 0.5mm, and the salient point by increasing above-mentioned size can ensure the tight fit of heat-radiation belt and backplate；
2, by increasing salient point at backplate expansion joint, ensureing that heat-radiation belt is close-fitting meanwhile, it is capable to anti-with backplate
Only in brazing process heat-radiation belt sideband fall off and the problem that causes radiator poor appearance, performance bad；
3, the apparatus structure designs advantages of simple, and dependable performance can be effectively prevented backplate expansion joint and connect with heat-radiation belt
Place is met because contact area is small, occurs the problem of traction in brazing process, the arrangement increases the aesthetics of radiator and uses
Therefore performance has good value for applications.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Attached drawing 1 is a kind of front view of backplate expansion joint anti-drop device；
Attached drawing 2 is the vertical view of attached drawing 1；
Attached drawing 3 is the assembly partial structural diagram of a kind of backplate expansion joint anti-drop device and radiator core body.
In figure：1, backplate, 2, expansion joint, 3, salient point, 4, heat-radiation belt, 5, heat-dissipating pipe.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment 1：
A kind of backplate expansion joint anti-drop device of the utility model, including backplate 1, the both ends of backplate 1 are each provided with one
Salient point 3, and expansion joint 2 is equipped with 1 plate of backplate, expansion joint 2 is arranged at the 1/3 of 1 plate body of backplate, and 2 both sides of expansion joint are symmetrical
2 salient points 3 are provided with, and 3 length of salient point is 9.5mm, is highly 0.5mm；Each salient point 3 of 2 both sides of expansion joint is apart from expansion
The distance for saving 2 centers is 8mm.
The utility model use process is as follows：During processing backplate 1, symmetrically set at 2 position of expansion joint of backplate 1
2 salient points 3 are set, ensures that backplate 1 is connect with heat-radiation belt 4 and compacts；Symmetrically increasing by two salient points at 2 center 8mm of expansion joint
