Bent pipe of heat exchanger

Abstract

The invention discloses a bent pipe of a heat exchanger. The bent pipe comprises a bent pipe body, a connecting sleeve and a speed measuring device; the bent pipe body consists of a straight pipe and a U-shaped pipe; the straight pipe is welded with the U-shaped pipe; an internal thread is arranged in the straight pipe; an external thread is arranged on the outer wall of the connecting sleeve; the connecting sleeve is connected with the internal thread in the straight pipe through the external thread on the outer wall; the speed measuring device is rotationally connected with the straight pipe; multiple electric heating chips are uniformly arranged on the inner wall of the U-shaped pipe, and are connected in parallel; a bracket is arranged on the outer wall of the straight pipe, and is provided with a rotating speed sensor; the speed measuring device consists of a rotating shaft, a tooth disc and blades; the tooth disc is connected with the upper end of the rotating shaft; the rotating shaft is rotationally connected with the straight pipe; and multiple blades are uniformly arranged on the outer wall of the rotating shaft. The bent pipe realizes precise temperature control of output air, prevents the phenomenon of uncomfortable human bodies caused by the temperature difference, meanwhile, can specifically embody the ventilation frequency and speed, is convenient to adjust the workload of the heat exchanger according to different indoor conditions, and is high in energy conservation.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger devices, in particular, the invention relates to a heat exchanger elbow. Background technique [0002] The total heat exchanger is a kind of outdoor fresh air that is filtered and purified, and then sent into the room after heat exchange treatment, and at the same time, the indoor polluted harmful gas is filtered and purified. It is a high-efficiency, energy-saving, and environmentally friendly high-tech product that is discharged outside after heat exchange treatment, and the indoor temperature is basically not affected by fresh air. [0003] The core device of the total heat exchanger is the total heat exchanger. The dirty air discharged from the room and the fresh air sent in from the outside not only exchange temperature through the heat transfer plate, but also exchange humidity through the micropores on the plate, so as to achieve both ventilation and air exchange. It also keeps the ...

Problems solved by technology

But in the process of total heat exchange, the display shows the temperature from the heat transfer plate, and the air passing through the heat transfer plate is transported in the pipeline, and the temperature will be lower than the displayed temperature when it contacts with the cold pipeline, so that People cannot accurately grasp the temperature. In addition, the traditional heat exchanger elbow only serves as a connection, and has a single function. It does not know the flow rate of the air in the pipe, and cannot specifically reflect the frequency and speed of air exchange.
