This application claims the priority of the Chinese patent application No. 200810018986.X filed on Jan. 30, 2008, which application is incorporated herein by reference.
The invention involves an automotive heater core with a coordinative structure between the retaining tabs on the side plates and the cooling fins. It belongs to the field of auto parts technology.
An 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. During the brazing process, as the materials used for cooling fins and header plate are different, they require different brazing temperature, thus the cooling fins are often melted where they contact the header, which affects adversely the effective cooling area and the appearance and quality of the products, and often the cooling fins drop out during brazing.
The purpose of this invention is to overcome the above shortages, and to provide a coordinative structure between the retaining tabs on the side plates and the cooling fins of an automotive heater core to prevent the partial melting, burning and the dropping out of the cooling fins during brazing.
The purpose is achieved through the coordinative structure between the bending tips on the side plates and the cooling fins of an automotive heater core including side plate (5) and cooling fins (7). It has the characteristics that described side plate (5) has two retaining tabs at both ends of the side plates where the cooling fins (7) end.
By using this structure the cooling fins are kept from touching the header and the friction between the cooling fins and side plates is enhanced so that partial melting, burning and dropping of the cooling fins are prevented to ensure brazing quality.
In the drawings: inlet pipe 1, outlet pipe 2, upper tank 3, header 4, side plate 5, tube 6, cooling fins 7, bottom tank 8, and retaining tabs 5.2.
