Wide-temperature-range movable heat supply system based on latent heat type heat transfer fluid

Abstract

The invention discloses a wide-temperature-range movable heat supply system based on latent heat type heat transfer fluid, which comprises a phase change micro heat pipe suspension, a phase change heat storage distributor, a heat exchange pipe, a temperature controller and a vehicle tank, and a low-temperature phase change heat storage unit, a medium-temperature phase change heat storage unit and a high-temperature phase change heat storage unit which are connected are arranged in the vehicle tank; the phase-change heat storage units are filled with the phase-change micro heat pipe suspension, the heat exchange pipes are distributed in the phase-change heat storage units, the two ends of each heat exchange pipe serve as connectors, the heat exchange pipes of the low-temperature phase-change heat storage unit, the medium-temperature phase-change heat storage unit and the high-temperature phase-change heat storage unit are sequentially connected, the external connection ends of the heat exchange pipes of the high-temperature phase-change heat storage unit are connected with the phase-change heat storage distributor, and the external connection ends of the heat exchange pipes of the medium-temperature phase-change heat storage unit are connected with the phase-change heat storage distributor. And the vehicle tank is provided with a temperature controller. Heat at different temperatures can be stored, and the heat storage capacity is improved by adding the phase change material, so that the movable heat supply capacity is improved, and the economical efficiency of the system is improved.

Description

technical field [0001] The invention relates to a wide temperature range mobile heating system based on a latent heat type heat transfer fluid, belonging to the field of mobile heating and phase change heat storage. Background technique [0002] my country's energy consumption is mainly concentrated in the industrial field, which accounts for about 70% of the country's total energy consumption, and the unit energy consumption of major industrial products is on average about 30% higher than the international advanced level. In addition to the relatively backward production technology and unreasonable industrial structure, the low utilization rate of industrial waste heat and insufficient comprehensive utilization of energy are important reasons for the high energy consumption. my country's energy utilization rate is only about 33%, which is about 30% lower than that of developed countries. 10%, at least about 50% of the industrial energy consumption is directly discarded as wa...

Problems solved by technology

At present, the most widely used is the hot water mobile heating device transported under atmospheric pressure within 100°C. The main advantages of this device are low equipment cost and short heat storage and release time, but the biggest disadvantage is small heat storage capacity and high transportation cost. , poor economic efficiency

In addition, some phase change heat storage mobile heating devices are used. The advantages of this device are large heat storage capacity and low transportation cost, but the disadvantages are large equipment investment and long heat storage and release time.
