Problems solved by technology
[0002] At present, there are usually three methods for car heating: 1. Independent heating, that is, through a heat exchanger, the heat generated by fuel combustion is sent into the compartment to heat the car. High difficulty
2. Use the engine cooling water as a heat source for heating, that is, introduce the engine cooling water into the heat exchanger in the compartment to achieve the purpose of heating the car, but the heat of the cooling water is small and the temperature is low, and the temperature of the cooling water is usually only 80-80°C when the engine is working. 90 ℃, therefore, in the cold winter in the north, not only can't heat the car, but also easily cause the engine to be overcooled, affecting the normal operation of the engine
Since the exhaust of the engine directly enters the heat exchanger, a large amount of corrosive engine exhaust will seriously corrode the tube wall of the heat exchanger, causing the exhaust of the engine to leak into the compartment through the heat exchanger from time to time. Heating poses a safety hazard

Embodiment Construction
[0010] In FIG. 1 , two installation holes for inserting the oil inlet nozzle 11 and the oil outlet nozzle 8 of the heat collecting sleeve 10 are drilled on the exhaust manifold 2 of the engine 1 . The heat collecting sleeve 10 is made of ductile iron into a cylindrical body with an annular sealing oil cavity 9, and the inner and outer sleeve spacing of the annular sealing oil cavity 9 is 2-3mm. There are two threaded oil inlet holes and oil outlet holes communicated with the annular sealing oil chamber 9 on the outer sleeve of the heat collecting sleeve 10 . The heat collecting sleeve 10 is placed in the inner cavity of the engine exhaust manifold 2 . The oil inlet nozzle 11 and the oil outlet nozzle 8 of the heat collecting sleeve 10 are all made of low-expansion stainless steel tubular bodies, and the two ends of the oil inlet nozzle 11 and the oil outlet nozzle 8 are respectively threaded, and there are lock nuts and The asbestos gasket sealed in the manifold installation ...

The invention discloses an automobile manifold heater, which comprises a heat collection sleeve and a heat exchanger. The heater is characterized in that the heat collection sleeve is a cylindrical body with an annular sealed oil chamber; the heat collection sleeve with the annular sealed oil chamber is matched with an engine exhaust manifold; the outer sleeve of the heat collection sleeve is provided with an oil inlet hole and an oil outlet hole which are communicated with the annular oil chamber; a tubular oil inlet nozzle and a tubular oil outlet nozzle of the heat collection sleeve are fixed in the oil inlet hole and the oil outlet hole on the heat collection sleeve respectively; the oil inlet nozzle of the heat collection sleeve is connected with an oil outlet pipe of the heat exchanger; and the oil outlet nozzle of the heat collection sleeve is connected with an oil inlet pipe of the heat exchanger through a circulation pump. The heater has the advantages of sufficient heat source, high temperature, convenient extraction, no consumption of fuel oil, simple structure, safe use, high heat efficiency, and no need of replacement of heat conducting oil, eliminates the potential safety hazard for heat supply in winter and therefore is a novel and unique automobile manifold heater product.
Description
technical field [0001] The invention relates to a warm air device, in particular to an automobile manifold warm air device, which is suitable for heating the automobile by using the waste heat of the exhaust manifold of the engine.
