Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0020] figure 1 It is a structural schematic diagram of the cooling system provided by the present invention, such as figure 1 As shown, the cooling system includes a radiator 1 , a fan 2 and a water pump 3 . Under the action of the water pump 3, the coolant flows from the engine into the radiator 1, and under the action of the fan 2, the cooling air flows through the radiator 1 to absorb the heat emitted by the radiator 1 to reduce the temperature of the coolant, and then cool down Under the action of the water pump 3, the coolant that flows out of the radiator 1 is sucked back into the engine through the engine water inlet pipe 5 to cool the cooling parts of...

Abstract

The invention discloses a method and a device for assessment of an engine cooling system and an excavator with the device. The method includes receiving data about temperature of cooling air before and after the cooling air flows through a radiator and radiating efficiency of the radiator, calculating a heat-balance saturation temperature according to the received data, judging whether the cooling system is available or not according to the heat-balance saturation temperature and an engine allowable temperature, and determining the temperature of coolant before the coolant flows through the radiator as the heat-balance saturation temperature in a heat balance state. Since whether the cooling system is available or unavailable is judged according to the calculated heat-balance saturation temperature, performance assessment of the cooling system is achieved before design of the cooling system; design parameter of the cooling system can be adjusted when the cooling result is judged to be unavailable so that useless detailed design can be avoided and people can choose the suitable cooling system to achieve better cooling effect.

Description

technical field [0001] The invention relates to a technology for judging the availability of a cooling system, in particular to an evaluation method for an engine cooling system, an evaluation device and an excavator with the evaluation device. Background technique [0002] The performance of the cooling system has a crucial impact on the life of the engine. However, the cooling effect of the cooling system of construction machinery is always calculated by the radiator manufacturer through software and provided to the buyer. That is to say, the buyer does not know the cooling effect. The calculation method of the heat dissipation effect of the system, and the relevant parameters of the cooling system can only be obtained through the prototype test. Therefore, the buyer cannot judge the availability of the cooling system during the design of the host, that is, he cannot independently evaluate the cooling system to select a suitable cooling system. Contents of the invention ...
