Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of diesel engine water tank, especially relate to a diesel engine water tank heat dissipation device with reduce cooling water loss structure. BACKGROUND

[0002] After the boiling of cooling water, the pressure in the water tank rises sharply, and if the pressure is not released in time or the release path is blocked, the vaporization of cooling water will be accelerated. This is mainly because when the diesel engine is running at high load or the ambient temperature is high, the heat generated by the heat dissipation system cannot be removed in time, resulting in the temperature of the cooling water exceeding the boiling point, and thus boiling. The vaporization of the boiling cooling water forms water vapor, and a large amount of water vapor will be directly discharged from the water tank, resulting in a large loss of cooling water.

[0003] The conventional methods mainly include: improving the heat dissipation efficiency of the radiator, such as increasing the area of the radiator or using high-efficiency cooling fins; improving the circulation of cooling water, such as checking the working state of the water pump and whether the pipeline is unobstructed; regularly checking and replacing aged water tank covers, pressure relief valves and other components; timely supplementing cooling water, and regularly maintaining the cooling system, such as cleaning the water tank and radiator, checking the quality of the coolant, etc. However, these methods also have some disadvantages: increasing the cost of heat dissipation efficiency, which may affect the overall design and appearance of the vehicle; improving the circulation of cooling water requires adjustment and maintenance of the system, which is labor-intensive; regular inspection and replacement of components require investment in manpower and time, and cannot completely avoid the loss of cooling water caused by accidental failure; merely relying on timely supplement of cooling water is a temporary solution and cannot fundamentally solve the problem of boiling of cooling water, and frequent supplement of cooling water will increase the maintenance cost and operation inconvenience, therefore, we hope to design a diesel engine water tank heat dissipation device with a novel structure to solve this problem.
