A heat exchange device for indoor heating

Abstract

The invention discloses a heat exchanging device for indoor heating. The heat exchanging device for indoor heating comprises a shell, a heat exchanging module unit and a fan, the fan is arranged at the rear end of the shell, and the heat exchanging module unit is arranged at the front end of the shell and comprises S-shaped microporous flat pipes bending into S shapes or a microporous flat pipe group composed of microporous flat pipes in parallel arrangement and in S-shaped communication, working media, fins, a communicating pipe, union elbows and electric heaters. Two ends of the communicating pipe are connected through the union elbows and the S-shaped microporous flat pipes or two ends of the microporous flat pipe group to form an enclosed space, the working media flow in the enclosed space circularly, and the electric heaters are in indirect or direct contact with the communicating pipe. The heat exchanging device for indoor heating is low in production cost and high in heat exchanging efficiency; particularly, a multi-channel parallel S-shaped communicating structure formed by the S-shaped microporous flat pipes or the microporous flat pipe group is adopted, and accordingly heat exchanging efficiency is improved greatly; a blocking piece blockage structure is adopted, and temperature equalizing performance and heat exchanging efficiency of the working media are improved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a heat exchange device for indoor heating. Background technique [0002] At present, indoor heating, such as northern Europe, North America and northern China, has a heating period of 5-7 months in winter. Due to the high maintenance cost of underground pipelines for central heating, there is heating waste in uninhabited or temporarily unoccupied rooms. , and the heating pipeline needs to be heated regularly, otherwise the underground heating pipeline is easy to freeze and block; especially in northern Europe, since natural gas and oil need to be imported, if this kind of energy is used by every household for heating and heating, one is to burn The efficiency is too low, and the second is to generate a large amount of greenhouse gases. Therefore, this type of energy is converted by power generation and then used by each household to improve energy utilization efficiency; at the same time...
