Black hole rotational flow heat collector

Abstract

The invention discloses a black hole rotational flow heat collector, and relates to an energy-saving electric heating technique. Aiming at the defects that the prior black hole heat flow device has big process difficulties, low product percent of pass and water leakage, the black hole rotational flow heat collector is disclosed and comprises a shell, a fluid inlet and a fluid outlet, wherein a volume reducer, a heat insulation pipe, an outer swirler, an outer black bole pipe, a middle swirler, a middle black hole pipe, an inner swirler and an inner black hole pipe are sleeved in the shell along the transverse direction in turn, and an electric heating piece in a block hole pipe uses electric power by rotational flow heating to embed pipeline fluid media in a circuitous and multi-time mode so as to collect heat and raise the temperature. The black hole rotational flow heat collector has the advantages of same temperature for the shell of the black hole pipe and the environment, high temperature generation in the black hole pipe, high electric heat utilization rate, simple production process, voltage resistance, water pressure resistance, small power, small volume, quick heating, accurate temperature control, high safety performance and long service life.

Description

technical field [0001] The invention relates to an electric heater for rapid heating of fluid in pipelines, in particular to a device for rapid electric heating of water, oil, all flowing liquids or gases in pipelines. Background technique [0002] An existing black hole heat flow device has been applied. The internal parts of this product are made of high-temperature rubber with upper and lower waterproof sleeves. The compression tightness is small, and water seepage still occurs; the production and implementation process is difficult; the waterproof parts at the electrode lead-out end are not tightly sealed, and there is water seepage Leakage problem; the electrical gap between the electrode lead in the heating tube and the metal heat transfer tube is small, the leakage current is large, and the product qualification rate is low; there is no temperature detection device. Although the electrothermal conversion utilization rate of this product is very high, it still has not ...
