Abstract
The utility model discloses a heater for mobile afterheat, which aims at providing a heater for coach carriage with a reasonable structure, good effect of heating and no wasting energy resources as well; the heater includes a motor and a vent pipe of the motor; wherein, the vent pipe is connected with a collector, the collector is provided with a cold blast intake pipe and a hot blast exit tube, the cold blast intake pipe or the hot blast exit tube is provided with a blower. The utility model can be used for heating in the carriage of motorbuses and medium buses.
Description
Technical field
The utility model relates to automobile-used heater, refers in particular to a kind of automotive residual heat heater that is used for large and medium-sized passenger vehicle.
Background technology
At present, the warm air air-conditioning of large and medium-sized passenger vehicle has two kinds of modes that heat, and one is hot-water heating, and two is that oil is warm.When adopting water heating system, be the hot water that produces when relying on the driving engine operation, send into the heat radiation hydrophone that is installed in the compartment, rely on blowing engine that heat is sent, thereby improve the ambient temperature in the compartment.The water temperature of the cooling water expansion tank of driving engine generally maintained between 80～90 ℃ when automobile normally moved, and hot water is sent into the radiator that is installed in a plurality of serial or parallel connections in the compartment by water pump, got back to driving engine after the circulation, and the backflow water temperature of this moment is between 20～30 ℃.The advantage of this mode is not produce operating cost, and its shortcoming is that it is relatively poor to heat heating effect because thermal energy is low, owing at the bottom of the return water temperature, reduced the power of driving engine, influences the service life of driving engine when serious in addition.
When adopting oily heating system, be to rely on the combustion engine incendiary oil to obtain heat energy, improve ambient temperature in the compartment by two kinds of heat transfer types.One: the combustion engine incendiary oil is obtained heat energy, utilizes this heat energy temperature of heated engine cooling water expansion tank once more, and it is reached about 100 ℃, sends into the radiator-water box heat radiation, and the driving engine return water temperature can be between 40～50 ℃; Its two: the combustion engine incendiary oil is obtained heat energy, and the direct heating ambient air improves ambient temperature.In the oily heating system of two kinds of modes, advantage is to have improved heating efficiency, has ensured good heating effect; Shortcoming is to have consumed a large amount of energy when obtaining heat energy, produces great operating cost, produces environmental pollution simultaneously in the process of burning and exhausting.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, provides a kind of rational in infrastructure, and it is good to heat heating effect, simultaneously the automotive residual heat heater of consumes energy not again.
The purpose of this utility model is achieved in that a kind of automotive residual heat heater, comprise driving engine, with the exhaust pipe of engine, be connected with heat collector on the wherein said freeing pipe, heat collector is provided with the cold wind inlet pipe and the hot blast that are communicated with passenger car respectively and goes out pipe, goes out to be provided with blower fan on the pipe at cold wind inlet pipe or hot blast.
Heat collector described in above-mentioned a kind of automotive residual heat heater is connected near on the waste pipe, can utilize engine exhaust heat so as far as possible, reduces heat-energy losses.
Blower fan described in above-mentioned a kind of automotive residual heat heater is a blowing engine, with in the cold wind inlet pipe that is installed in the heat collector outside for good.
Heat collector described in above-mentioned a kind of automotive residual heat heater can be by shell, many fixing in the enclosure heat transmission copper pipe and the fin that is fixed on the heat transmission copper pipe periphery constitute, total cross-sectional area of heat transmission copper pipe is good with the cross-sectional area that is equal to or greater than freeing pipe, can not increase the resistance of exhaust of driving engine like this.
The connecting portion that heat collector described in above-mentioned a kind of automotive residual heat heater and cold wind inlet pipe and hot blast go out pipe is provided with air storage chamber, to guarantee fully contacting of air and radiating fin.
After the utility model adopts said structure, the waste gas residual heat that produces when directly utilizing the driving engine operation can absorb rapidly and retain the heat energy in the used heat and produce high-grade heat energy as the energy, reaches the purpose that heats heating, compared with prior art, have following characteristics:
1. utilize engine waste heat as thermal source, do not consume any energy fuel, do not have any operating cost, do not have any pollution.
2. the temperature height of engine exhaust can reach 300～400 ℃, and cal val is big, heats up rapidly, and is applied widely; Except that blower motor, there is not any movable parts, the reliability height.
3. reduced blowdown presssure and exhaust temperature, made that discharging is more smooth and easy and greatly prolong the ternary catalyzing unit life-span.
4. simple installation.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
The specific embodiment
Consult shown in Figure 1ly, a kind of automotive residual heat heater of the present utility model comprises driving engine 1, with driving engine 1 freeing pipe 2, on freeing pipe 2, be connected with heat collector 3, heat collector 3 is connected near on the freeing pipe 2 of driving engine 1, to utilize the waste gas residual heat of driving engine 1 as far as possible, reduce heat-energy losses; Heat collector 3 is to be made of the radiating fin 3c that shell 3a, many are fixed on the heat transmission copper pipe 3b in the shell 3a and are fixed on heat transmission copper pipe 3b periphery, it is 7～ 9.52mm copper pipe that heat transmission copper pipe 3b can adopt internal diameter, the arrangement mode of many heat transmission copper pipe 3b can adopt square or rhombus, the selection of heat transmission copper pipe 3b quantity determines that by the cross-sectional area of freeing pipe 2 total cross-sectional area of heat transmission copper pipe 3a is good with the cross-sectional area that is equal to or greater than freeing pipe 2; Radiating fin 3c can rise by the internal diameter of heat transmission copper pipe 3b greatly by the rise mode of pipe of machinery, thereby radiating fin 3c closely is fixed on the heat transmission copper pipe 3b outer wall, and heat transmission copper pipe 3b institute absorbed heat is distributed; Be provided with air storage chamber 3d at heat collector 3 and the connecting portion that cold wind inlet pipe 4 and hot blast go out pipe 5, to guarantee fully contacting of air and radiating fin 3c; Heat collector 3 is provided with the cold wind inlet pipe 4 and the hot blast that are communicated with passenger car respectively and goes out pipe 5, is provided with blower fan 6 on cold wind inlet pipe 4, and blower fan 6 is a blowing engine, is installed in the cold wind inlet pipe 4 in heat collector 3 outsides.
When the utility model specifically used, when driving engine 1 work, the waste gas that burning produces directly entered heat collector 3 after freeing pipe 2 is discharged, discharge behind noise silencer 7 then.When passenger car needed warm air, blower fan 6 was started working, and the high-temperature gas of discharging during engine operation is by heat collector, and the heat collector absorption is also retained a large amount of heat energy.By the cold wind inlet pipe 4 that is communicated with passenger car, the cold air in the passenger car blasted carry out interchange of heat in the heat collector 3, produce the high-grade hot air, and go out pipe 5 along the hot blast that is communicated with passenger car and enter passenger car, thereby improve the interior temperature of passenger car.
