Abstract
A method of evenly distributing a fluid into a plurality of tubes of a heat exchanger comprises inserting a scroll fluid distributor 1 into a header and communicating fluid through the scroll distributor so that the fluid is distributed evenly into the tubes of the heat exchanger. A scroll distributor comprises of a sheet of material rolled up with gaps between each roll and a surface of the sheet having a plurality of through-holes through which the fluid communicates. The scroll distributor may be located in an outlet header. The sheet material may be rolled, moulded or cast into shape. Applications include heat exchangers or condensers for heating, refrigeration or air conditioning and heat pumps. The shape and number of holes may be variable and altered to suit the particular application. Advantages include improved performance of the heat exchanger.
Description
IPag:e:1 Title Scioll Distributor flaciçgpnd When gas.or:.fluid is injectedinto atube or header pipe:ofaheat:exchanger at one point, the distnbution ofthe gis or fluid to the tubes or micro channels attached to the header is variable and dependent on their position in the assembly, this is seen in heat dissipation analysts across the face of any heat exchanger where differing temperatures can be measured I he tubes or micro channels at closest proximity to the input point recea e the greatest volume and pressuic of gas or fluid This means that the efficiency of the heat exchanger aries wffh some areas being very efficient and others being not so efficient as the gs.or fluid does not reach 411 areas in.ti*'same volume or at tbe'same pressure.
Statement of invention
If:air or.fiuid is applied to the end or centre of a scroil,:the nature of a scroll cause the air orfluid. to, flow around the scrolL.
The present invention proides a scroll distributor to distribute the refrigetant gas or fluid evenly within the inlet and or outlet tube or header of a heat exchanger, so that it distubutes equally through each and every tube and micio channel of the heat exchanger, this balances the thstnbution of the liquid or gas across the tubes or micro channel dud increases the efficiency of heat or fluid transfer. The sCroll nature of thc distributor encourages the fluid or gas to distribute evenly in a controlled manner, the position size and number of the outlet holes or louvers is infinitely variable and can be altered to suit the size. andperformance requirements of each application.: Advaiilägcs :rrheath,anta of the scroll diflributor is that the point ofinict can be infinitely variable and the position of the outlet louvers or holes can be adjusted to ensure accurate distribution of the fluid or gas The equal distribution of gas oi fluid across the heat exchanger improves the efficiency and performance of the unit The unit is manufactured horn sheet material, with holes or louvers punched as required, then a simple rolling process to create the an and distribution gap between each roll, this makes the product cheap and simpiie:to manufacture. ge1

Introductionto drawins
Diawing 1 -shows a the scioll distributoi (1) being a coiled piece of material with louvers or holes 2) cut into it at vanous positions Item A. shows a heat exchanger comprising the inlet ( 3) and the outlet (4j These header tubes are combined vvith tubes rmcro channel tubes ( 5) and heat dissipation fins ( 6) The scroll distributor would be assembled inside the inlet tube oi header or outlet tube ( 3,4) m the orientation required to accept the input point for the gas or fluid and match the output requn ements for the tubesHor:nucro channel tubing.
Diawmg 2 -shows the distribution of the fluid or gas through the scroll distributor and how the holes or louvers in the distributor can he married exactly to the output position dependent on the position of the micioehannel tube The size and position of the lou er or hole canto adjusted to compensate forpressure drop and fiO* requirements.
Drawing 3 -shows a cross section through a typical inicrochannel tube (1) and its location in a heat exchanger connected by brazing between the inlet header tube ( 2) and the outlet header tube ( 3), this shows the position of the mierochannel tubes in place and how the:scroll distributor would match these points.
Drawing 4 -shows the sci oil distributor I, with louver outlets 2 and hole outlets 3, there is no limit to the design or shape of the outlets, these can be modified to suit each application and the flo' direction and volume required 4 shows ans input point on the length of the di%tributor, this is variable m size, position and shape 6 shows the central or end input position for the scroll distributor 7 is an example that the position and size of the holes or lot vets injhfinitely vriabieapd. can he modifie4 to suit each application.
