Abstract
High temperature of the radiator group is harmful to the power system and hydraulic system. In order to improve the heat dissipation performance of the loader, the flow field characteristics of the cooling chamber are analyzed by simulation and heat balance test. Firstly, the mathematical model of heat flow is established. Secondly, the flow field in the cooling chamber under different speeds is simulated based on CFX. And then the influence of fan position and internal flow field distribution on radiator performance is studied. Through the simulation of four different distances, it is concluded that the optimal distance between cooling fan and radiator is 76 mm. Finally, the heat balance test system based on wireless sensor network is established, and the simulation results are verified. The test results show that the heat dissipation performance of the whole machine meets the requirements after optimization. In this paper, the proposed scheme can dynamically adjust the heat dissipation performance and make the loader excavator in an efficient and energy-saving operation state.

Summary
With the development of information technology, the Internet of things has become a major event in our daily life of the generation. There are three methods for evaluating the heat dissipation performance of construction machinery: First, thermal balance vehicle test. This method is the most direct and simple, but it has long cycle, high cost and poor repeatability. Qu et al [11] analyzed the air flow field inside the power room of liquefied petroleum gas (LPG) vehicles and found that the air velocity and the range of thermal fluid have a certain influence on the cooling effect of the heat balance system. We set up a heat balance test system based on wireless sensor network to evaluate the performance of the excavator loader system in Sect.
