Abstract
The invention relates to an air heater for a diesel engine. The air heater for the diesel engine comprises a shell, wherein binding posts are respectively arranged on two sides of the shell; one end of a resistance wire, which is bent to be form multiple U shapes connected mutually, is connected with the binding posts; the other end of the resistance wire is connected with a connecting base. The air heater for the diesel engine is simple in structure and compact in size; the resistance wire is bent to be in the U shapes and is connected with the connecting base to form a whole, so that the service life of the resistance wire is greatly improved, and the resistance wire is not easy to wear; meanwhile, the resistance wire is made of a nicochrome material, so that the heating speed is quick, the heat cycle time is long, the requirement that the diesel engine is started quickly at a lower temperature is met, the starting time of the diesel engine is shortened, and meanwhile, the emission standard of the diesel engine after starting is also ensured.
Description
Technical field
The present invention relates to diesel engine intake heating field, relate in particular to a kind of air heater for diesel engine.
Background technique
Air heater is to solve an accessory that starts (title cold start-up) under diesel engine machine cold state, its working principle be by heater switch on (being generally about 1 minute) make it to reach 800 ℃～1000 ℃ high temperature, air in heated diesel suction tude, makes diesel engine under the atmosphere environment of-10 ℃～35 ℃, start smoothly (heating before claiming) in advance.In prior art, air heater is all installed on air inlet pipe of diesel engine inside, because diesel engine intake tube space is less, cause air heater difficult arrangement, installation is wasted time and energy, the resistance wire of existing air heater is generally flat filament, the thinner thickness of flat filament, resistance wire is the dither due to diesel engine at the elbow part through bending, long-time, easily produce and wear and tear, existing air heater cannot meet diesel engine startup fast at a lower temperature simultaneously, exist starting time long, the shortcoming of difficulty in starting, and existence starts the problem of rear discharge severe overweight.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and the air heater of a kind of knot for diesel engine is provided, and has volume small and exquisite, saves diesel engines space, advantage easy for installation.
The technical solution adopted in the present invention is as follows:
An air heater for diesel engine, comprises housing, and there is wiring terminal the both sides of housing respectively device, and the one end that is bent into a plurality of interconnected " U " shape resistance wire is connected with described wiring terminal, and the other end is connected with connecting base.
Its further technological scheme is:
Described connecting base fitting apparatus is in the middle part of described housing;
Be positioned at the inwall of described housing, in the joint of connecting base and housing returning apparatus the first insulation spacer;
Be positioned at the inwall of described housing, in the joint of described wiring terminal and housing returning apparatus the second insulation spacer;
Surrounding in described housing has " U " shape groove;
Described resistance wire adopts nichrome material to make.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, volume is small and exquisite, resistance wire is bent into U-shaped and is connected to form an integral body with connecting base, greatly improved the working life of resistance wire, make resistance wire not easy to wear, resistance wire adopts nichrome material to make simultaneously, and rate of heating is fast, the thermal cycle time is long, meet diesel engine and start fast at a lower temperature, shortened the starting time of diesel engine, also guaranteed the emission standard after diesel engine starting simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes housing 1, the surrounding of housing 1 has " U " shape groove 7.There is wiring terminal 2 both sides of housing 1 respectively device, the one end that is bent into a plurality of interconnected " U " shape resistance wire 3 is connected with described wiring terminal 2, the other end is connected with connecting base 4, connecting base 4 is installed on the middle part of housing 1, on connecting base 4, have the mounting hole (not shown) for resistance wire interlocking, resistance wire 3 is connected to form an integral body with connecting base 4, effectively raises the working life of resistance wire, makes resistance wire not easy to wear.Resistance wire 3 adopts nichrome material to make, and rate of heating is fast, and the thermal cycle time is long, meets diesel engine and starts fast at a lower temperature.Be positioned at the inwall of housing 1, joint returning apparatus the first insulation spacer 5 in connecting base 4 with housing 1.In the inwall of housing 1, joint returning apparatus the second insulation spacer 6, the first insulation spacers 5 and 6 conduction insulating effects of the second insulation spacer in wiring terminal 2 with housing 1.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
