The evaporative heat exchanger that recovers heat from the surface of the component and the household miniature combined heat and power device

Abstract

The invention relates to an evaporative heat exchanger for recovering heat dissipation from the surface of components and a household miniature cogeneration device. The evaporation heat exchanger is used to recover heat dissipation from the surface of components in the household micro cogeneration device. In the closed box of the household miniature cogeneration device, the evaporating heat exchanger includes an evaporating section and a condensing section, and the evaporating section has interconnected fluid channels, and the fluid channels are filled with absorbing components For the working fluid that dissipates heat on the surface, the condensation section is set on the return water pipeline of the domestic micro cogeneration device, and the evaporation section and the condensation section are connected through a working fluid exchange pipeline. Compared with the prior art, the evaporative heat exchanger of the present invention is used to recover the surface heat dissipation of the components in the household micro cogeneration device, which not only increases the heat recovery, but also avoids the attenuation of power generation capacity and the decline of energy efficiency caused by the intake air of the prime mover as the cooling medium The problem.

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...

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
