Abstract

The utility model relates to a regenerative preheater for large and medium-sized trucks, which comprises a casing.The internal of the casing housing is equipped with a heat-insulation layer.The internal of the casing is equipped with a waste heat recoverer and a waste heat exchanger.The waste heat recoverer is formed by a plurality of heat pipes and fins are arranged on the heat pipes.The waste heat exchanger is formed by a plurality of cold air inlet pipes and a plurality of hot air outlet pipes.A plurality of clean airducts are connected between the cold air inlet pipes and the hot air outlet pipes.The regenerative material is filled both between the inner wall of the casing and the waste heat recoverer and between the inner wall of the casing and the waste heat exchanger.The regenerative preheater is compact in structure, wherein the recovery, storage and conversion equipments for the waste heat of the locomotive tail gas are arranged in one casing and the casing is small in occupation space.Only by modifying the locomotive exhaust pipe, the regenerative preheater can be connected with the locomotive to be used, thus is convenient in operation.Since the regenerative preheater arranged at the position of the exhaust pipe has a small resistance, the preheater has no effect on the normal operation of the engine.

Description

Big-and-middle-sized truck accumulation of heat preheater

Technical field

The utility model relates to a kind of big-and-middle-sized truck accumulation of heat preheater.

Background technology

In the winter of cold district, the startup of big-and-middle-sized truck is difficulty relatively, be the temperature of rising anti-icing fluid, generally before cold start-up, need that this kind method danger coefficient is higher with blowtorch baking automotive oil drain pan, easily make machine oil rotten, and fire using in fields is roasting just more inadvisable sometimes, and effect is bad, wastes time and energy, and easy again breaking out of fire or damage machine, cause unnecessary loss.By electric preheating pipe heating or the device of electricity consumption muff insulation is solved, and automobile parking is in the place that power supply is arranged, connect with the mains during starting to come to engine prewarming by electrothermal tube or electric muff, this quadrat method exists the problem of complicated operation, easily produces leaky simultaneously, causes engine charged, there is potential safety hazard, and preheating time is long and use cost is high, and the electric heater of 220 volts of power supplys of this employing too relies on power supply, is difficult to practicality in the open air.

Adopt the preheater of dc source, limited by the storage battery electric weight, the heating DeGrain, even some effects are arranged, the also wearing and tearing that strengthened automobile because heating-up temperature is not high.The setting height(from bottom) of radiator directly influences the installation site of preheater, the height of water level of water tank is lower than preheater water inlet height, because the impeller blade end face is a level, impeller suction is easy to cause preheater not intake inadequately during work, and delivery port is positioned at upper shell side downside and makes preheater can not ponding cause the electrothermal tube no-water dry combustion and damage; This preheater adopts to be gone up the lower end face and compresses the sealing ring sealing since expand with heat and contract with cold or sealing ring aging, in use produce and leak, and cause the preheater coil to damage or electric leakage through regular meeting; Because this preheater produces fault through regular meeting, can't differentiate the motor damage still is fuse blows, needs the whole preheater of dismounting to judge and to keep in repair.

The utility model content

The purpose of this utility model provides a kind of big-and-middle-sized truck accumulation of heat preheater, solving big-and-middle-sized truck engine starts under low temperature condition and needs preheating, the tradition preheater need utilize civil power, and the locus of utilization is tied, can not saves energy, and the deficiency that the waste heat of vehicle exhaust can not be recycled.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of big-and-middle-sized truck accumulation of heat preheater comprises casing, and the enclosure interior of described casing is provided with heat-insulation layer, described box house is provided with waste-heat recoverer and residual-heat exchanger, wherein waste-heat recoverer is made of some heat pipes, and the left end of heat pipe exposes outside casing, and heat pipe is provided with fin; The left upper portion of casing is provided with cool air hose, and the lower right side of casing is provided with warm-air pipe; Described residual-heat exchanger is made of some cold wind inlet headers and some hot-blast outlet collectors, connects some clean air ducts between cold wind inlet header and the hot-blast outlet collector; The right-hand member of cool air hose connects the cold wind inlet header, and the left end of warm-air pipe connects the hot-blast outlet collector, all is filled with heat-storing material between the inwall of described casing and waste-heat recoverer and the residual-heat exchanger.

The beneficial effects of the utility model are: compact conformation, the recovery of motorcycle tail gas waste heat, all in a casing, casing takes up room little, and is easy to use for storage and conversion equipment, only need to change at locomotive blast pipe position, equipment connects therewith, just can use, and equipment is installed in the blast pipe position, resistance is very little, and the engine operate as normal is not had influence.
