Technical Field

The utility model relates to a water-cooled engine heat dissipation field especially relates to the heat abstractor of petrol engine that stews.

Background

At present, a heat dissipation device of a conventional water-cooled gasoline engine consists of a fin radiator and a fan which are fixed in size and completely sealed, the heat dissipation mode mainly depends on wind generated by automobile running to carry away heat of the fin radiator, and the heat dissipation effect is limited by only depending on the fan. In some construction sites such as fire fighting, irrigation and the like, the engine is required to provide power required by the water pump, the engine is in a static state at the moment, and the phenomenon that the engine coolant boils frequently occurs due to the fact that the engine is not radiated by wind generated by high-speed movement, and the engine stops working due to faults.

Further, the heat exchange medium is one of water and cooling liquid.

In conclusion, the heat abstractor of water-cooled gasoline engine, heat exchange medium flow at the constant speed in shell-and-tube heat exchanger, can increase the pipeline length in the shell-and-tube heat exchanger when shell-and-tube heat exchanger heat transfer area is not enough in order to increase heat transfer area and heat exchange medium. Simultaneously owing to cancelled the great space occupation of having saved the engine of radiator fan, can know from this, gasoline engine's heat abstractor's advantage lies in: the water-cooled gasoline engine matched with the water pump in the fields of fire fighting equipment, hand-lifting motor-driven fire pump sets, irrigation and the like can be reduced in size, the heat exchange efficiency is improved, and equipment failure and long-time halt caused by boiling of engine coolant are avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The high-temperature cooling liquid outlet 11 of the engine is communicated with a high-temperature cooling liquid inlet 61 of a shell-and-tube heat exchanger through a high-temperature cooling liquid water pipe 1 of the engine, and the cooling liquid outlet 62 of the shell-and-tube heat exchanger is communicated with a cooling liquid inlet 21 of the engine through a low-temperature cooling liquid water pipe 2 of the engine; the heat exchange medium water inlet 63 on the shell-and-tube heat exchanger 6 is connected with the water outlet 31 of the engine water pump through the heat exchange medium water inlet pipe 3, the heat exchange medium water outlet 64 on the shell-and-tube heat exchanger 6 is connected with the water inlet 41 of the engine water pump through the heat exchange medium water outlet pipe 4, and the heat exchange medium circulates through the engine water pump.

The heat exchange area of the high-temperature cooling liquid of the engine and the low-temperature heat exchange medium is increased in a countercurrent mode.

The utility model discloses in, shell-and-tube heat exchanger 6 is non-integrated into one piece, detachable because different areas, different season ambient temperature are different, require differently to heat transfer area. Fluid sealing quick plugs which can be quickly inserted and expanded are welded at the inlet 61 end and the outlet 62 end of the cooling liquid pipe of the shell-and-tube heat exchanger 6, and at the water inlet 63 end and the water outlet 64 end of the heat exchange medium pipe of the shell-and-tube heat exchanger 6.
