Description

Technical Field

[0001] The invention relates to the technical field of heat exchange systems, and in particular to a novel water-cooled engine heat exchange system. Background Art

[0002] Since water has a high specific heat and good heat transfer performance between parts and cooling medium, most modern automobile engines are cooled by water. Engines that use water as a cooling medium are called water-cooled engines. Coolant is water, which is transported by a water pump and flows through the engine and water radiator. When the car is running, the water flowing through the radiator is forced to cool by the windward airflow or by a fan. The temperature of the coolant (water) is adjusted by the valve of the thermostat. Water cooling uses water (or antifreeze) as a cooling medium to take away the heat of the high-temperature parts of the engine to ensure the normal operating temperature of the engine. The water cooling system consists of a water pump, a radiator, a fan, a thermostat, a water jacket and water pipes. The coolant of the water cooling system is in the water jacket of the engine. After absorbing the heat of the high-temperature parts, the temperature rises. It is cooled by the fan and the windward airflow through the radiator, and then the cooled coolant is pumped into the water jacket for circulation cooling.

[0003] With the development of science and technology, and the enhancement of people's awareness of environmental protection, the ventilation and exhaust conditions of generator sets have become extremely limited, and there are higher requirements for the structure and use environment of generator sets. Therefore, it is particularly important to control the temperature in the silent box of diesel generator sets under such conditions. The common practice in China now is to use a muffler + cooling water tank to solve the problem. In a high temperature environment, the engine exhaust pipe is directly connected to the engine exhaust port to the muffler. Since the exhaust port is directly discharged, the temperature of this section of the exhaust pipe in the silent box will be very high, and then radiate to the entire silent box, causing high temperature protection shutdown. Under such a background, it is very necessary to invent a new diesel engine heat exchange system. Summary of the invention
