Furthermore, since the installation of the heater in the heating device according to the invention can be done on the engine assembly line, the cost of installing such a heating device is significantly reduced. At the same time, the waste heat from the heater, which can be operated independently from the engine, is also used to heat the oil in the oil pan, which significantly improves engine starting characteristics, especially cold start characteristics, and reduces engine wear and tear. .

There isn't. This also provides direct physical contact between the oil pan and the heater, allowing waste heat from the heater to be released into the oil pan and heat the oil therein during operating conditions.

給する為に、燃料供給管との接続口も設けられている。As shown in the figure, lubricating oil from the engine 3 collects in the oil pan 2. The whole is designated by 1, and the socket for the heater, which is independent of the engine and can in particular be operated on liquid fuel, is designated by 4. The heater 1 is a so-called water heater whose inlet 9 and outlet 10 are connected to the refrigerant cycle of the engine 3. This refrigerant cycle is not shown in detail. In this embodiment, the heater 1 forms a complete pre-assembled unit, the outer casing wall 7 of the heater 1 having, in addition to an inlet 9 and an outlet 10 connected to the engine coolant cycle, a waste gas outlet sleeve 1). It is installed. The waste gas passes through the heat exchanger of the heater 1 from the waste gas outlet sleeve 1) and is released into the atmosphere. Although not shown in detail, the heater 1 is equipped with an air absorption device, and the air absorbed from the surroundings is supplied by a blower to a burner (not shown in detail) of the heater 1 as combustion air. In order to supply fuel to the burner of the heater 1, a connection port with a fuel supply pipe is also provided.

きる。In this embodiment, the socket 4 of the heater 1 is formed by an opening 5 with a flange 6 in the oil pan. A completely pre-assembled heater 1 is inserted into this opening 5 and fixed to the flange 6, for example with bolts. Heater 1
Since it is already formed as a pre-assembled unit, it can be installed on the normal assembly line of the engine 3.

おける消耗は著しく減少する。As seen in the drawing, most of the heater 1 is inside the oil pan 2 and is surrounded by oil within the oil pan 2. Heater 1 operates and releases heat,
When the refrigerant in the refrigerant cycle of the engine is thereby heated, the heat is transferred through the outer casing wall of the heater 1 to the oil by direct contact with the oil in the oil pan 2 of the engine, heating it. Thereby, waste heat that is always generated by the heater 1 and normally lost is effectively used to heat the oil in the oil pan 2. Therefore, in such an embodiment of the heating device according to the invention, not only is the advantage that the structure of the heater 1 is simple and the installation saves maximum space, but also the heater 1 is connected to the engine 3. Not only the refrigerant in the refrigerant cycle but also the oil in the oil pan 2 is heated. This improves the starting characteristics of the engine 3, especially the cold start characteristics. This is because preheating the oil in the oil pan 2 reduces internal resistance, and the heated oil exhibits a high lubrication effect even at low outside temperatures. As a result, wear and tear during cold starts is significantly reduced.

加のオイルクーラは省略できる。When the burner of the heater 1 is switched off and the heater 1 no longer supplies heat, the oil in the oil pan 2 can also be cooled by using a suitable circuit. This is because the refrigerant in the refrigerant cycle of the engine 3 passes through the heater 1, thereby cooling the oil in the oil pan. Accordingly, an additional oil cooler, which is sometimes required in the past, can be omitted to cool the oil of the engine's lubrication cycle during vehicle operation and to maintain the lubricating properties of the lubricating oil in an optimum range.

イルを集中的に加熱若しくは冷却することができる。Furthermore, the ribs 8 shown in the drawings are attached to the casing outer walls 7 and 7'.
It is possible to expand the heat transfer area of the casing outer walls 7 and 7' to the oil in the oil pan 2 and strengthen the heat transfer to the oil in the oil pan 2. In this case, by appropriately modifying the ribs 8, the heat flow of the heaters 1 and 1' to the oil in the oil pan 2 can be changed in an advantageous direction, thereby making it possible to effectively heat or cool the oil. Taking into account the geometrical conditions of the oil pan, it is possible, for example, to intensively heat or cool the oil in the oil pan 2, where a relatively large amount of oil collects.

ジンによって異なる。Of course, in addition to the embodiments shown here, experts can make various changes or modifications as necessary. For example, the location where the heater 1' is integrated into the oil pan 2 can be selected so as not to interfere with the operation of the oil pump or the like. The mounting position also depends on the shape of the oil pan 2. However, the shape of the oil pan 2 differs depending on the engine.

可能となる。In the automotive heating device according to the present invention, the installation space required for the heater that can be operated independently from the engine is as small as possible, and the connecting hose is as short as possible, so even when there is almost no space in the engine compartment, It is possible to install such a heater independent of the engine. In particular, the heater can not only heat the refrigerant in the engine's refrigerant cycle, but also heat the oil in the oil pan, or cool the oil in the oil pan when the heater is not operating.
