Abstract
The article describes the tests and determination of the temperature characteristics of highly efficient heat transfer units (heat pipes (HP)), which can be used in heat and mass transfer devices, for example, in the process of drying vegetables and fruits. To test and determine the temperature characteristics of HP, a test setup for medium-temperature HP was created and a number of tests were carried out to determine how the dependence of the temperature change of the condenser and the HP evaporator at various angles of inclination, the working fluid, body material, HP wick material was selected, the influence of the number of mesh wick and influence of pressure. All characteristics are presented in graphs and tables.
Highlights
Problems of energy saving processes, as well as the development and implementation of highly efficient equipment and technology for the development of small and medium-sized businesses is an urgent problem.Energy costs for the implementation of heat and mass transfer processes in the primary processing of raw materials and food products account for up to 70% of the total energy expended
HP 9 evaporating part is aHPached to the heating body 5, which consists of a drain pipe 7, a heating element 11, a thermostatic device 14, a switch 15, a thermometer 8 to determine the temperature of the water inside housing 5, which simulates the flow of thermal energy using the heating element 11
Conductivity of the coolant, the heat transfer. It can be seen from the graphs that the slope angle of the HP has liHPle effect on the increase in the water temperature of the case 5 from it, it can be concluded that the main influence on the flow of thermal energy will be affected by the working fluid, the thickness of the wick, the thermal coefficient of the HP material and the wick
Summary
Problems of energy saving processes, as well as the development and implementation of highly efficient equipment and technology for the development of small and medium-sized businesses is an urgent problem.Energy costs for the implementation of heat and mass transfer processes in the primary processing of raw materials and food products account for up to 70% of the total energy expended.
