Abstract
The utility model discloses a high efficiency heat exchanger, comprising a fixed tube sheet, heat exchange tube bundles and a heat conduction fin. The heat transfer tube bundles compose a first heat exchange channel. The stainless steel and the alloy compose the heat conduction fins used for heat exchange, which are closely arranged on the external surface of the heat transfer tube bundle, forming a second heat exchange channel. The interval between the fins is 1. 5 - 4 mm. The first heat exchange channel and the second heat exchange channel compose the metal vane type air heat exchange channel. The heat transfer tube bundle bodies in different parallel connection modes can compose various tube passes to meet the requirement of the current rate and the flow rate. Both the heat exchange tube bundle and the heat conduction fin can be made of the stainless steel material or the alloy pipe material for better contact and fixation. The good heat conduction contact can be ensured.
Description
One, technical field
The utility model relates to a kind of internal circulation type liquid heat-exchanger, and especially second heat exchanger channels is air and the heat exchanger that passes through the fin heat exchange, belongs to the heat exchange field of engineering technology.
Two, background technology
Be used to weave, the shell-and-tube heat exchanger of department such as petrochemical industry, chemical industry, power, printing and dyeing, metallurgy, its structure heat exchanger has an end to end circulation canal in the casing of a sealing, heating surface bank is installed among the passage, be made up of fixed tube sheet, heat-exchanging tube bundle etc., liquid cycles through heat-transfer pipe with required optimum flow rate and carries out heat exchange.But heat exchange efficiency still awaits improving.
In this industry, need very big heat exchange area and the good heat exchanger of antiseptic property, as the heat exchanger that is used for the cooling usefulness of spandex when silk spray refrigerant just there is this requirement.
Three, summary of the invention
The utility model purpose is: a kind of high-performance heat exchanger is provided, has smaller volume and bigger heat exchange area, and the good heat exchanger of antiseptic property.
The purpose of this utility model is to realize like this, its structure is, heat exchanger is in the housing of a sealing, heating surface bank constitutes first heat exchanger channels, be made up of fixed tube sheet, heat-exchanging tube bundle, heat transmission fin etc., the heating surface bank outer surface is the heat exchange of solid matter heat transmission fin fixedly, constitutes second heat exchanger channels, interval between the fin constitutes metal chip air heat exchanger channels at 1.5-4mm.
The utility model can constitute various tube sides to satisfy the requirement of flow velocity and flow with different parallel waies with the heating surface bank body, heat-exchanging tube bundle, heat transmission fin all can use stainless steel material or compo pipe material, can be fixing with contact preferably, to guarantee good heat conduction contact, the utility model can reach heat exchange area more than up to a hundred square metres with the volume of one cubic metre of less than, can satisfy the heat exchange requirement of industries such as weaving, petrochemical industry, chemical industry, power, printing and dyeing, metallurgy.
Four, description of drawings
Fig. 1 is the utility model structural representation
The flange port 5 of shell end 1,2, heat-exchanging tube bundle 3, heat transmission fin 4, heat exchanger, end housing 6, fixed tube sheet 7, side shell 8 among the figure.
Five, the specific embodiment
As shown in the figure, critical piece is made up of fixed tube sheet 7, heat-exchanging tube bundle, heat transmission fin 4 etc., and heat-exchanging tube bundle places between the tube sheet, and the utility model adopts stainless steel, also can adopt the special corrosion resisting alloy pipe to be used for the heat-exchanging tube bundle of heat exchanger, be used for weaving, oil, chemical industry heat exchanger.As heat-exchanging tube bundle, described tube bank can be low tooth thread pipe or bellows or screwed pipe or T shape pipe as stainless-steel pipe.Have more anticorrosive superior, characteristics that heat transfer property is good, and save equipment investment cost.Heat-exchanging tube bundle 3 struts caliber with the interior mode that expands of fixedly employing tube bank of heat transmission fin 4, guarantees tube bank and the good thermo-contact of fin.
Heat-exchanging tube bundle, heat transmission fin are made unit one by one earlier, and then coincide, and carry out the tube side parallel connection in the end, and the interval between the heat transmission fin is especially at 1.8-4mm, and thickness adopts the fin of 0.1-0.5mm.
Claims (2)
1, a kind of high-performance heat exchanger, form by fixed tube sheet, heat-exchanging tube bundle, heat transmission fin, heating surface bank constitutes first heat exchanger channels, it is characterized in that constituting the fixedly heat exchange heat transmission fin of solid matter of heating surface bank outer surface with stainless steel or alloy, constitute second heat exchanger channels, interval between the fin constitutes metal chip air heat exchanger channels at 1.5-4mm.
2, by the described high-performance heat exchanger heat exchanger of claim 1, it is characterized in that interval between the heat transmission fin especially at 1.8-4mm, thickness adopts the fin of 0.1-0.5mm.
