Background technology

As shown in Figure 1, 2, be tail gas heater unit and noise elimination hot-water heating type heater unit structural representation, in large and medium-sized passenger car, heat at present, adopt fule heater or utilize the tail gas heating, when they water circulation system and the cooling water car system is common when forming a loop, the upper end of heater unit casing 13 or noise elimination water heating type warm-air box body 15 is equipped with by what DC motor drove and increases pump pressure 14, because it is short service life to increase pump pressure, general only assurance of producer used 2000 hours, and fault rate is very high.

Dust stratification easily in the heater unit heat exchanger tube adopts the ash disposal of ash cleaning agent method, and poor effect and increase operating cost adopts the method for manual deashing, and is cumbersome again.

Summary of the invention

The purpose of this utility model is a kind of saving cost of invention, and remove automatically easily dust stratification in the heater unit heat exchanger tube not with the energy-conservation heater unit of booster water pump.

For realizing above purpose, the technical solution of the utility model provides a kind of automatic ash disposal and not with the energy-conservation heater unit of booster water pump, comprise handle, locating plate, end cap, tube sheet, heat exchanger tube, cutoff board, base pipe, the cigarette gate seat, the cigarette door, coolant inlet pipe, coolant outlet pipe and casing, end cap is located at an end of casing, the cigarette gate seat is located at the other end of casing, locating plate is located in the end cap, base pipe is located at box house, its two ends communicate with end cap and cigarette gate seat respectively, between two tube sheets, be provided with at least one heat exchanger tube, fix by tube sheet and cutoff board, the cigarette door is located in the middle of the cigarette gate seat, coolant inlet pipe and coolant outlet pipe are located at the casing outside, it is characterized in that the boost pump of not establishing DC machine and being driven on casing; In heat exchanger tube, be provided with the conveyor screw of ash disposal automatically, be connected with handle by locating plate.

The described conveyor screw first is in heat exchanger tube, and it two is to be processed by metal filament or bonding jumper.

Because the water pump that drives by driving engine in the passenger vehicle, powerful, boost pump is not established in the utility model outside, can reach original effect fully, can reduce infrastructure cost and complexity, significantly reduce operating troubles, the conveyor screw deashing mechanism is installed in heat exchanger tube simultaneously, when automobile start, when brake speed changes greatly, owing to action of inertia conveyor screw deashing mechanism generation crank motion, dust just can fall automatically, makes the cleaning dust stratification reach easy to be reliable.

The utility model has the advantages that the saving cost, and remove dust stratification in the heater unit cleaning heat exchanger tube easily, simple in structure, practical, respond well.
