Radiator

Abstract

The invention belongs to the field of radiators, and particularly relates to a radiator which comprises a radiator main plate, a core body, a liquid feeding chamber and a liquid drainage chamber. Thecore body is fixed by the radiator main plate and composed of multiple radiating pipes, and the liquid feeding chamber and the liquid drainage chamber are fixed to the corresponding radiator main plate. The radiator main plate is formed by assembling multiple main plate units, the two sides of each main plate unit are provided with a first fixing groove and a second fixing groove, the two sides ofeach main plate unit are further provided with a first fixing part and a second fixing part, each radiating pipe is fixed in a fixing strip hole defined by the first fixing grooves and the second fixing grooves of two adjacent main plate units and matched with the end of the radiating pipe in shape, and every two adjacent main plate units are connected through the first fixing parts and the second fixing parts. According to the radiator, the radiating pipes and the radiator main plate can be stably, easily and conveniently assembled, the pressure bearing capacity is large, and the leakage rate is low.

Description

technical field [0001] The invention belongs to the field of radiators, in particular to a radiator. Background technique [0002] In vehicle engineering, the radiator is a very important component, which is mainly used to cool the cooling medium in the vehicle. The cooling medium in the vehicle includes but is not limited to: water, oil, and air. [0003] As a water-cooled radiator, the medium pressure is about 2kg. But for oil-cooled radiators, the pressure of the cooling medium will increase to 20-30kg. [0004] Especially for oil-cooled radiators, the excessive pressure puts forward high requirements on the tightness and strength of the heat dissipation pipes and radiator main boards. [0005] Radiators are divided into plate-fin radiators, tube-fin radiators, and tube-and-belt radiators in terms of their structure. [0006] For vehicles, more tube-fin radiators and tube-band radiators are used. [0007] For the cooling medium with small flow and low pressure, the tr...

AI Technical Summary

Problems solved by technology

[0014] The problem caused by this is that due to too many components, it is easy to have missing welding or deformation through brazing or other welding methods

Use in a high-pressure environment often does not last long

And in the welding process, it must be assembled to a very standard to be successfully welded, and the operation is very difficult
