Description
Technical field
The utility model relates to heavy automobile cab heating and the dim wind apparatus that defrosts, and is specifically related to flat-tube radiator as air heater with 3 D ribs for truck.
Background technology
At present, the radiator heater that uses on the heavy motor vehicle mainly contains two kinds of pipe type and corrugated tube types.Show according to data at home and abroad introduction and the heavy motor vehicle condition of service that travels in China " three Norths " area, fin and tube radiator heater both domestic and external and pipe rock radiator heater, when ambient temperature is-25 ℃, the temperature that can not satisfy pin, head and the chest region of chaufeur is not less than 15 ℃, its major cause is that these two kinds of heater heat dispersions are low, the requirement of heating and defrosting in the out of reach heavy automobile cab.Influence the low reason of heat-sinking capability: when air is mobile rapidly in face of the edge of radiator fin or heat-radiation belt, on the surface of radiating gill or heat-radiation belt, just form one deck and hindered the boundary 1ayer that conducts heat, along air-flow direction, length increase along with radiating gill or band, the thickness of this boundary 1ayer also increases gradually, thereby the localized heat transfer rate is descended rapidly with the increase of its thickness.Therefore preceding two kinds of heater heat-sinking capabilities are low, the requirement of heating of long-term use out of reach and defrosting.
The heater heat-sinking capability of present domestic fin and tube radiator and pipe rock radiator is low, has above-mentioned defective equally, influences the service conditions and the work efficiency of chaufeur.Analyze the heater structure and the performance of Germany's benz heavy motor vehicle fin and tube radiator and pipe rock radiator, make a service test simultaneously, its as a result heating capacity be about 3000kcal/h.Institute's heat requirement is to supply with heat with heater in operator's compartment in the heavy automobile cab, how much what supply with heat is by loss of heat amount decision in the operator's compartment, as calculated, analysis of experiments Germany benz heavy motor vehicle uses the heating capacity of cabin space needs at China's cold district, at 4000～5000kcal/h, could satisfy the needs under the harsh environment in the open air.
Summary of the invention
The utility model provides a kind of novel heavy duty automobile three-dimensional rib plate flat-tube radiator heater at the deficiency of above-mentioned prior art, reaches the requirement of heavy motor vehicle in cold district's heating and defrosting.Its technical scheme is as follows:
Flat-tube radiator as air heater with 3 D ribs for truck, mainly comprise fan, three-dimensional rib plate flat-tube radiator, case lid assembly, casing assembly, maneuvering system and motor, the three-dimensional rib plate flat-tube radiator is made the high 0.3-0.6mm of inner rib plate through specialized equipment and profile cutter, the high 2-3mm of outer fin, pitch of fins is the three-dimensional inside and outside fin flat tube of 1-2mm, every three-dimensional rib plate flat tube two ends and stay bearing plate welding, stay bearing plate and the welding of two ends end socket, weld two side seal boards again, go back oil inlet and outlet place welding turnover oil pipe assembly on the at both ends end socket; Three-dimensional rib plate flat-tube radiator and casing assembly and case lid assembly coupling.Motor adopts metal to be connected with the plastics interference fit with fan.The high 0.4mm of described three-dimensional rib plate flat-tube radiator inner rib plate, the high 3mm of outer fin, pitch of fins are 2mm.
Use proof through entrucking, under equal conditions improved 67%, improved manyly than fin and tube radiator heater heat dissipation capacity, reached heavy motor vehicle in the travel requirement of heating and defrosting of Han Qu than pipe rock radiator heater heat dissipation capacity.
It is that the radiator of heat exchange element is made heating plant that the utility model is equipped with the three-dimensional rib plate flat tube, and it is little to have a volume, and heating load is big, can strengthen the machine oil heat radiation, saves advantages such as the heat supply energy again.Be suitable for the iron-clad horses heavy motor vehicle, also be applicable to the north---serial vehicles such as benz and import benz heavy motor vehicle, can be used for liquid-cooled engine, also can be used for air-cooled engine.Three-dimensional rib plate flat-tube radiator heater is used for operator's compartment heating and defrosting belongs to initiative both at home and abroad.
The utility model is compared 4 times of cost-cuttings with the pipe rock radiator heater of German import, has reduced foreign exchange, obtains remarkable economic efficiency and social benefit.
