Problems solved by technology

The heat dissipation control of the current construction machinery engine is only for the radiator of the water tank, and does not involve the intercooler. Therefore, the heat dissipation control of the engine will frequently start and stop the fan when the engine is working, and it is difficult to integrate the cooling effects of the intercooler and the water tank. for optimal thermal control

Abstract

The invention discloses a crane and an engine thermal management cooling device thereof. The engine thermal management cooling device comprises an engine cooling bag which comprises an intercooler (12) and a water tank (14), wherein the intercooler is connected in an air inlet pipeline of an engine (60); the water tank is arranged at the rear side of the intercooler (12) and is connected in a liquid cooling system of the engine (60); the engine thermal management cooling device is characterized in that the engine cooling bag also comprises an electronic control fan component (16) which is arranged at the rear side of the water tank (14) and comprises a plurality of fans used for cooling the intercooler (12) and the water tank (14); and the engine thermal management cooling device further comprises a controller (20) which is connected with the fans and is used for selectively controlling the running states of all the fans in the electronic control fan component according to the heat emission condition in the running process of the engine. The invention is capable of leading the engine of the crane to obtain better heat dispersion performance.

Description

technical field [0001] The invention relates to engine thermal management cooling technology, in particular to a crane and an engine thermal management cooling device thereof. Background technique [0002] Traditional engines use air cooling, water cooling (including using various coolants to form a liquid flow circuit) or a combination of air cooling and water cooling to achieve heat dissipation. As the requirements for engine performance are getting higher and higher, the thermal management technology of the engine has also been developed rapidly. [0003] Chinese Invention Patent Application Publication No. CN101328830A (application date June 18, 2008, application number 200810124954.8) discloses a method for thermally managing an engine, wherein an internal combustion engine is provided with a cylinder block coolant passage and a cylinder head coolant passage The first coolant circuit is also provided with a second coolant circuit, which communicates with the first cool...
