Evaporation heat exchanger for recycling part surface dissipated heat and household miniature combined heat and power generation device

Abstract

The invention relates to an evaporation heat exchanger for recycling part surface dissipated heat and a household miniature combined heat and power generation device. The evaporation heat exchanger isused for recycling the part surface dissipated heat in the household miniature combined heat and power generation device, and the evaporation heat exchanger is arranged in a closed box body of the household miniature combined heat and power generation device. The evaporation heat exchanger comprises an evaporation section and a condensation section, the evaporation section is provided with fluidchannels which communicate with each other, the fluid channels are filled with working media used for absorbing the part surface dissipated heat, and the condensation section is arranged on a water return pipeline of the household miniature combined heat and power generation device. The evaporation section communicates with the condensation section through a working medium exchange pipeline. Compared with the prior art, the evaporation heat exchanger is used for recycling the part surface dissipated heat in the household miniature combined heat and power generation device, recycled heat is increased, and the problems that the power generation capacity is attenuated and the energy efficiency is reduced due to the fact that inlet air of a prime motor serves as a cooling medium are solved.

Description

technical field [0001] The invention relates to an evaporative heat exchanger and a household miniature heat and power cogeneration device, in particular to an evaporation heat exchanger and a household micro heat and power cogeneration device which recover heat from the surface of components. Background technique [0002] Distributed Energy System (DEC) is a comprehensive energy utilization system with multi-input and multi-output capabilities. It is based on the concept of energy cascade utilization and integrates power generation, heating and cooling. , Compared with the traditional centralized energy supply system, it has obvious advantages. The combined heat and power (CHP) system is one of the most typical, dynamic and practical forms of energy supply in distributed energy. Its application originated in the United States in the 1880s. The CHP system fully realizes the utilization of different grades of energy. The application principle is "temperature matching and cas...

Problems solved by technology

As a result, large air intake and exhaust holes must be opened on the box body, which is not only unfavorable for noise control, but also increases the power consumption, noise and investment cost of the fan. At the same time, the heating of the intake air will cause the prime mover to Power generation capacity attenuation, efficiency decline
