Detailed Product Description: | Air temperature gasifier works: it can be the core of the heat exchanger unit is to get a strong heat from the atmosphere in the smallest possible space. Domestic manufacturers of air-temperature gasifier heat exchanger means more use of anti-embroidered aluminum finned tubes. In the absence of optimal design, most exist in about shortcomings: large equipment, high cost, lack of product flow. I believe the reason (factor except artificial aspects) mainly due to the heat transfer area. In order to achieve a certain flow, can only increase the fin, after several studies and trials, the use of some techniques, a large extent to solve this - problem. The following brief description to do this, and I hope the domestic air-temperature gasifier can play a positive role in the promotion. The general structure of the finned tube: finned tube having a central tube, the outer tube of radial fins, the liquid flow in the pipe, and rely on the fins to absorb heat is transferred to the external environment in order to achieve a liquid heat pipe fluid vaporized. We passed several experiments and screening, selecting the new fin tube is different from the above elements, the heat transfer coefficient of the former increased by 50%. Action principle of this fin tube, is to LPG as an example to do media work following analysis: When the LPG flow in the tube (the vertical axis direction by the bottom-up), the cooling fluid which is close to the inner wall of the finned tube of liquid first completion of heat exchange with the outside world as a tiny bubbles vaporized, when tiny bubbles together into a gas, desorbed achieve boiling, but due to the liquid petroleum gas in contact with the wall a short time, the convection flow within the pipe under the action of gravity only the whole upper and lower portions of the finned tube wall temperature uneven, resulting finned tube heat transfer coefficient is no big increase, finned tube overall heat transfer performance not fully utilized, which is currently the several air-temperature gas LPG the presence of finned tubes are drawbacks. And the Company's ATC series with built-wick and that spiral belt technology has greatly enhanced the finned tube heat transfer coefficient than not using the technology finned tubes to increase 5-2.0 times, using the built-in core and heat that spiral banding technique works as follows. (1) Internal wick used as one of porous stainless steel, wound into a cylindrical shape after the wind close to the finned tube wall, when the heat core infiltration in liquefied petroleum gas or natural gas liquids which, due to the surface tension of liquid capillary the role of the phenomenon, the liquid film in the narrow gap between the wick and finned tube wall between the adsorbed tiny bubbles formed by finned tube heat vaporization, when the upward flow of tiny bubbles to form larger bubbles from the suction liquid core holes on the surface to escape, eventually level off at a gas up to boiling, and tiny bubbles from the wick after wick liquids supplemented by the hole into the gap formed among micro-convection heat and because of built-in suction liquid core and that spiral belt between liquid isolated, to avoid prematurely carried out by the latter within the finned tubes, and is conducive to the generation of fine bubbles. (2) Internal screw guide the flow direction of the liquid is changed, the flow direction without the built-in spiral flow diversion zone is vertical, and later built that spiral band, the flow direction is upward spiral (similar to the flow direction A Archimedes spiral), increasing the flow of liquid, prolonged contact time with the finned tube of liquid, increase the separation of the liquid between the wick and that spiral belt formed air flow which carries a small part droplets constantly wet during ascent fin wall above the liquid level, gas absorption and updraft again the same temperature drops along the inner wall portion of the downward direction of flow, liquid level and temperature of the liquid mixture slightly improved the temperature at the surface, and enhance the inner fin tube boiling, and more fully to improve the overall performance of finned tube heat exchangers on the two technology applications, significant improvements to the uniformity of the finned tube wall temperature, and further improve the heat density, obviously improve the heat transfer coefficient of the finned tube improve the heat transfer effect of air temperature gasifier, more effectively ensure gasification of liquefied LPG, LNG and so on. Gasification section having a built-wick and that spiral to the fin tubes of the group consisting of highly efficient heat exchange and thermal conductivity with a spiral section has a built-fin tubes (for the increase after the gasification gas temperature) and means there is the main regulator means monitoring phase regulator control west and gas regulator system, can in a certain volume of liquid by combining prevention device, safety relief tube from the air temperature gasifier the maximum guarantee the gasification capacity.
