Problems solved by technology
However, these plumbing exhaust heaters cannot completely close the flue due to the unreasonable structure of the smoke door. The high-temperature exhaust gas can still flow into the coil heating channel through the muffler hole to heat the circulating water. If the engine water tank temperature continues to rise, the power cooling fan will Frequent start-up, the power loss of the general water tank power cooling fan is about 10% of the total engine power. Heater heat energy utilization efficiency is greatly reduced, and in serious cases, it is even impossible to drive

Embodiment 1
[0018] Such as Figure 1-3 As shown, a plumbing tail gas heater described in this embodiment mainly includes an outer barrel body 3, an inner barrel body 11 is arranged inside the outer barrel body 3, and a heating gas is formed between the inner barrel body 11 and the outer barrel body 3. The inside of the inner barrel body 11 is the tail gas discharge flue 12. The heating gas path channel 4 is provided with a heating water coil 5, and the heating water coil 5 surrounds the inner barrel 11, and the two ends are correspondingly provided with The coil positioning ring 10 at the intake end and the coil positioning ring at the gas outlet, a plurality of sound-absorbing holes 17 are arranged symmetrically on the coil positioning ring 10 at the gas intake end, and can also be arranged on the coil positioning ring at the gas outlet end as required There is a sound-absorbing hole 17, and the top of the coil positioning ring 10 at the intake end is provided with a slide-type smoke doo...
Embodiment 2
[0020] The difference between this embodiment and Embodiment 1 is that the shapes of the first closed door 9 and the second closed door 8 are oval.

The invention disclose a water-heating exhaust heater, which mainly comprises an outer barrel body and an inner barrel body, wherein a heating air channel passage is formed between the inner barrel body and the outer barrel body; a heating water channel coil pipe is arranged in the heating air channel passage; an air inlet end coil pipe positioning ring and an air outlet coil pipe positioning ring are correspondingly arranged at two ends of the heating water channel coil pipe; a plurality of noise damping holes are symmetrically formed in the air inlet end coil pipe positioning ring; a sliding plate type smoke door is arranged at the top end; the sliding plate type smoke door comprises a first sealing door and a second sealing door which are symmetrical distributed; a position of a top surface of the second sealing door is lower than a position of a bottom surface of the first sealing door; a smoke door sliding block is fixedly connected with each top end of the first sealing door and the second sealing door respectively; and two smoke door sliding blocks are matched with a movable screw rod arranged on the outer barrel body, so as to be capable of driving the first sealing door and the second sealing door to do face to face motions or reversing motions. According to the heater, the smoke door adopts the structure of two symmetrically distributed sealing doors, so that the opening and closing of the two sealing doors are controlled by driving the screw rod to rotate positively and negatively, and the smoke door can be closed completely.
Description
technical field [0001] The invention relates to a heating heater for a motor vehicle compartment, in particular to a plumbing exhaust heater. Background technique [0002] In recent years, in order to further save energy, the hot water in the water tank and the exhaust gas heater are used for heating together. Most of the vehicles in northern my country use the combination of high-temperature antifreeze liquid in the water tank and exhaust gas heating for heating in winter. The radiator is also heated by the high-temperature water in the water tank to the exhaust heater for the second time, and then the water pump drives the circulation to the radiator and defroster, and then uses the fan to force heat dissipation to increase the temperature of the air in the compartment, so as to achieve the heating effect of the passengers in the compartment. However, these plumbing exhaust heaters cannot completely close the flue due to the unreasonable structure of the smoke door. The hig...
