Problems solved by technology

The dry exhaust pipe used in vehicles has a large heat dissipation, and the heat of the exhaust pipe is not easy to dissipate in the airtight cabin, and there are safety hazards such as fire. Therefore, most marine engines use water-cooled exhaust pipes that exchange heat between the coolant and the exhaust. , and because the flow of air in the cabin is poor, marine engines generally use seawater and coolant for heat exchange
[0003] At present, the water-cooled exhaust pipe and the heat exchanger of the marine engine are two independent parts. The layout of the whole machine is not compact, many pipelines are exposed, and the appearance of the whole machine is not beautiful enough.

Abstract

The invention discloses an integrated heat exchange system of a marine engine. The integrated heat exchange system of the marine engine comprises an exhaust chamber, a coolant chamber and a seawater chamber, wherein the coolant chamber is integrated on the outer side of the exhaust chamber, and a coolant inlet, a small circulation channel, a thermostat channel and a coolant outlet are formed in the coolant chamber; a thermostat is arranged in the thermostat channel, and the small circulation channel and the thermostat channel correspondingly communicate with the coolant outlet; and the seawater chamber is integrated in the thermostat channel, and seawater flows in the seawater chamber so as to exchange heat with a coolant in the thermostat channel. According to the integrated heat exchangesystem of the marine engine, the heat exchange between the coolant and exhaust gas and the heat exchange between the seawater and the coolant can be achieved, the machine is compact and beautiful, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to the field of engines, in particular to an integrated heat exchange system for marine engines. Background technique [0002] The operating environments of marine engines and vehicle engines are different: marine engines are placed in the cabin, and the ventilation and heat exchange conditions are harsh. The differences in the above operating conditions determine that there are large differences in the structure of the exhaust pipe and radiator. The dry exhaust pipe used in vehicles has a large heat dissipation, and the heat of the exhaust pipe is not easy to dissipate in the airtight cabin, and there are safety hazards such as fire. Therefore, most marine engines use water-cooled exhaust pipes that exchange heat between the coolant and the exhaust. , and because the flow of air in the cabin is poor, marine engines generally use seawater and coolant for heat exchange. [0003] At present, the water-cooled exhaust pipe and the he...
