Abstract

PURPOSE:To facilitate the maintenance of the internal-combustion engine and accessories of a heat exchanger, by providing a shell made of a flexible material to contain a heat medium and by providing pillars for supporting the internal- combustion engine in the shell, so that the pillars can be separated from the shell. CONSTITUTION:An internal-combustion engine 5 of water tightness is mounted in a shell 1 made of a flexible material. A heat medium liquid 3 is contained in the shell 1. The engine 5 is hung with a support 6 on pillars 2 whose upper ends are engaged with hooks 35 attached to the upper end of the shell 1. Since each pillar 2 is attached by screws 30 to an L-shaped plate 29 secured on the bottom plate 31 of the shell 1, the pillar can be separated from the shell. The support 6 is fitted with springs 33 on the flanges 34 of the pillars 2. Since the hooks 35 on the top of the shell 1 can be disengaged from the pillars 2 to haul down the shell, maintenance work is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves bringing an internal combustion engine into contact with a heating medium housed in a can,
The present invention relates to a heat exchange device that heats a heat medium using heat generated during operation of an internal combustion engine, and particularly relates to a support structure for an internal combustion engine.

In an internal combustion engine, oil elements, fuel filters, air filters, etc. sometimes need to be cleaned or replaced. In addition to such maintenance, repair of the internal combustion engine itself may be necessary.

However, if the internal combustion engine is located inside the can, maintenance work is difficult to perform.

In particular, in the case of a structure in which the internal combustion engine is completely immersed in a liquid heat medium such as water contained in a can, it is necessary to
In this case, the various maintenance operations mentioned above are not possible. However, it is undesirable to have to remove the internal combustion engine from the can body or access the can body each time these operations are performed, as the work becomes complicated. Furthermore, the task of attaching and detaching the internal combustion engine to the can itself is not easy.

Therefore, an object of the present invention is to facilitate maintenance and repair work of an internal combustion engine and its auxiliary equipment arranged inside a can body.

Another object of the present invention is to reduce the volume of the can so that it can be carried.

According to the present invention, the heat exchange device is configured to bring an internal combustion engine that drives a compressor into contact with a heating medium housed in a can, and heat the heating medium with heat generated during operation of the internal combustion engine. However, in particular, the heat exchanger is such that the can body is constructed of a flexible material, the internal combustion engine is supported by a strut inside the can body, and the strut and the can body are arranged so that they can be separated from each other. is obtained.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration of an embodiment of the present invention, and FIG. 2 shows a top view of a support in the embodiment. In FIG. 1, a cylindrical can body 1 is made of a flexible material such as rubber, and is shaped like a bag and can be expanded and contracted in the vertical direction. Of course, since the can body 1 has an air layer, it has a heat insulating effect like a heat insulating tank.

A liquid heat medium 6 such as water is housed inside the can body 1.
Although it can be discharged through the faucet 62, the heat medium filter usually has a liquid level at the position indicated by symbol 4.

Further, an internal combustion engine 5 having a watertight structure is disposed inside the can body 1 . The internal combustion engine 5 is suspended from a support 2 disposed inside the can 1 via a support 6 as shown in FIG. Here, a hook 5, which is attached to the upper end of the can body 1, is fixed to the earth end of the support 2.

On the upper surface of the internal combustion engine 5, in addition to a fuel filter 7 and an intake silencer 8 for the internal combustion engine 5, a compressor 9 driven by the internal combustion engine 5 is also provided. The fuel filter 7, intake silencer 8, and compressor 9 all have
The entire body is immersed in the heat medium 3. In addition to the muffler 12, an exhaust gas heat exchanger 13 is also provided in the middle of the exhaust pipe 11 of the internal combustion engine 5. The muffler 12 and the exhaust gas heat exchanger 16 are also immersed in the heat medium 6.

In this way, the internal combustion engine 5 and its auxiliary equipment are all immersed in the heat medium 6. Therefore, the noise generated during operation of the internal combustion engine Jul 5 is reduced to lIg.

Note that the upper surface of the can body 1 is covered with a lid 14 having a heat insulating structure shown by a chain line.

Heat such as exhaust gas generated during operation of the shunted internal combustion engine 5 is transmitted to the heating medium 6 and warms it. The temperature of the heating medium 6 heated in this way is taken out to the outside of the can 1 by the heat exchanger 15, and is used for heating or hot water supply, for example.

The outlet portion of the exhaust pipe 11, the inlet portion of the intake pipe 16, and the inlet portion of the fuel supply pipe 17 are all arranged above the can body 1. In addition, the suction pipe 18 and the discharge pipe 1 of the compressor 9
9 is also exposed above the can body 1.

Now, between the suction pipe 18 and the discharge pipe 190 of the compressor 9,
As shown in FIG. 6, refrigeration circuit elements such as a condenser 21, an evaporator 22, and an expansion valve 26 are connected therebetween.

For example, the condenser 2 of the heat bong device configured in this way
1 is disposed in a heat medium 25 of a heat medium tank 24 separate from the can body 1. As a result, when the compressor 9 is driven, the heat medium 25 is heated. The temperature stored in this heat medium 25 can be extracted by a heat exchanger 26. According to this configuration, desired heating and hot water supply can always be obtained by only occasionally driving the internal combustion engine 5. Note that it is possible to cool the heat medium 25 by switching the flow direction of the refrigerant between the condenser 21 and the evaporator 22.

Now, returning to Fig. 1, each of the plurality of supports 2 is fixed to the bottom plate 31 of the can body 1, and is tapped into the L cedar board 29 with screws 30, so the can body 1 and the supports 2 are separated from each other. It is possible.

A support 6 for the internal combustion engine 5 is placed on the flange 4 of the column 2 via a spring 6.

The embodiment having the above configuration includes the internal combustion engine 5 disposed inside the can body 1 and its auxiliary machines, such as the combustion engine filter 7, the air filter 27 in the intake silencer 8, the starter 28, etc. To perform maintenance or repair work on the compressor 9, first take the heat medium filter out of the can through the faucet filter 2, then remove the hook 65 at the top of the can 1 from the support 2, and pull down the can 1 as shown by the chain line. Let's do it. In this way, the internal combustion engine 5, its auxiliary equipment, and the compressor 9 are substantially exposed outside the can body 1, making maintenance and repair work very easy.

Further, in order to remove the internal combustion engine 5 from the support column 2, it is only necessary to simply pull up the support body 6, so the operation is very simple.

Furthermore, since the plurality of supports 23 and 60 can be removed from the bottom plate 31 of the can body 1, the can body 1 can be contracted and carried, and of course can be easily stored.
