Clamping Structure between Header and Side Plate of Automotive Heater Core
This invention involves clinching tabs between the header and the side plate of an automotive heater core, which belongs to the field of auto parts technology. Said structure includes the headers (4) and the side plates (5), the characteristics of said structure are that there are clinching tabs (4.2) located at the center of the minor dimension of the headers (4) and the center of the ends of the side plates (5). Said clinching tabs (4.2) are clamped to the center of the ends of the side plates (5) to secure the side plates (5) and the header (4) of the automotive heater core. By using the clinching tabs, the connection between the side plates and headers is firmer and the overall angular rigidity of the automotive heater core is enhanced, thus the cooling fins are better protected from damage.
This patent application claims the priority of the Chinese patent application No. 200810018984.0 filed Jan. 30, 2008, which application is incorporated herein by reference.
FIELD OF THE INVENTIONThe invention involves an automotive heater core, particularly a clamped structure between the header and the side plate of an automotive heater core. It belongs to the field of auto parts technology.
BACKGROUND OF THE INVENTIONAn automotive heater core is a radiator dissipating heat into the car cabin using cooling water from the engine, it includes: inlet pipe, outlet pipe, upper tank, bottom tank, header, tube, cooling fins and side plate. Old art seeks to secure the side plates to the header by brazing the cooling fins to the side plates so as to prevent the cooling fins from damage and to strengthen the overall structure. This old art makes the connection between the side plates and the header not secure and firm enough, which causes the comparatively low overall angular rigidity of the automotive heater core, and the cooling fins are not well protected from damages.
SUMMARY OF THE INVENTIONThe purpose of this invention is to overcome the above shortages, and to provide a clamped structure between the header and the side plate of an automotive heater core to connect them more firmly.
The purpose is achieved through the clamped structure between the header and the side plate of an automotive heater core including the headers (4) and the side plates (5). It has the characteristics that there are clinching tabs at the center of the minor dimension of the said headers (4) and the center of the ends of the side plates (5). Said clinching tabs (4.2) are clamped to the ends of the side plates to secure the side plates to the header of the automotive heater core.
By using this clamped structure, the connection between the side plates and headers is firmer and the overall angular rigidity of the automotive heater core is enhanced, thus the cooling fins are better protected from damage.
In the drawing: inlet pipe 1, outlet pipe 2, upper tank 3, header 4, side plate 5, tube 6, cooling fins 7, bottom tank 8, and clinching tabs 4.2.
DETAIL DESCRIPTION OF THE INVENTIONIn reference to
Claims
1. A clamping structure between a header and a side plate of an automotive heater core comprising the headers, the side plates, each header has clinching tabs located at the center of the board for connecting with the side plates, the clinching tabs are clamped to the ends of the side plates.
