Definitions
- the present invention relates to heat sources-cum-sinks, and especially to heat pipes constituted as thermal conditioning clothing for humans.
- a heat pipe assembly for use when heat source and heat sink are remote, comprises a heat receiver element of heat pipe form, that is having an encased reticulated structure including wicking and void continua, a heat sink element, a liquid pump, a vapour duct connecting the heat receiver element and the heat sink element, and a liquid duct connecting the heat sink element with the heat receiver element via the liquid pump.
- the wicking constitutes a liquid duct and the void continuum a vapour duct.
- a hollow liquid duct without wicking can have advantages. Indeed the provision of a liquid pump and an unwicked liquid duct can enable quite small ducting to be employed in supplying a heat receiving heat pipe of considerable heat receiving surface area.
- the operation of assemblies in accordance with the invention can be independent of orientation, ie the heat sink may be sited well below the heat receiver element.
- the invention confers yet another advantage when heat sinks in the form of heat pumps are employed, if not in other situations, in that the liquid pump performs the function of a non-return valve preventing back-flow of the water.
- the invention is thus particularly suitable for use when the heat receiving heat pipe element is in conformable garment form such as is described in UK Patent Specification 8106782, and it is therefore a feature of the invention that the heat receiver element may be in sheet heat pipe form, may be in conformable sheet heat pipe form, and may even be in conformable heat pipe thermal conditioning garment form, comprising a flexible reticulated structure including a wicking element, an impermeable flexible envelope containing the structure, there being vapour flow channels within the envelope and substantially coextensive with the wicking element.
- the wicking element may be on one face, the working or heat receiving face of the structure.
- the flexible reticulated structure may, for example, be one formed in a three dimensional weaving process involving picking yarns out and thermosetting plastics warp and weft fibre elements, with the wicking perhaps constituting part or all of the weft or warp fibre or perhaps comprising non woven sheets attached to or interwoven by the structure.
- heat pipes according to the invention are of sheet construction.
- it may be of value for elements of the structure which support the thickness of the heat pipe to have higher stiffness than the rest, and be, for example, formed of metal or metallised plastics.
- a suitable wicking may comprise glass fibre tow or cord., eg 'REFRASIL' (TM), or metal wick.
- An alternative flexible reticulated structure may include an uncut velvet structure such as is described in UK Patent Specification 1028141. Typically this could be formed of nylon, polyester, or carbon or glass fibre, with or without a stiffening agent.
- the envelope suitably comprises a heat sealable plastics film, and is preferably metallised, eg aluminised. It may be a laminate of various materials, eg Mylar (RTM).
- RTM Mylar
- liquid distribution means may be incorporated in the heat receiver element, the liquid distribution means comprising an elongate perforate tube contacting the wicking throughout its perforate length.
- the elongate perforate tube may simply be a tube with discrete perforations throughout its working length and the contact between that and the wicking obtained by wrapping wicking around the tube and/or poking strands thereof through the perforation.
- the perforation may be realised in a slit, and perhaps the wicking edge retained in the slit perhaps by tube resilience, or perhaps by thread sewn through the wicking and passing around the tube.
- the perforation of the distribution tube is advantageously sited in a substantially uppermost part thereof.
- the liquid distribution means are preferably disposed substantially uppermost therein.
- the tube may be endless, eg annular, and are preferably formed of resilient, flexible plastics material.
- the distribution means are therefore preferably disposed so that in use they will overlie the length of the wearer's shoulders, as epaulettes, with wicking emanating to either side thereof.
- the distribution means of the present invention are particularly suitable for use in heat pipe assemblies where the heat sink element is not in heat pipe form but merely supplies cooled liquid, perhaps condensing vapour received from the receiver element to provide the liquid.
- a liquid transfer means/wicking interface such as is the subject of the present invention, will be required.
- the usual requirement for substantially a vacuum within the apparatus, and the exclusion of contaminants, may be met on the one hand by the provision of evacuation pump means as part of the heat pipe assembly and on the other by suitable isolating valve means in the connector by which elements to the assembly are disconnected.
- the assembly may include a liquid-pump for supplying the liquid to the liquid distribution means.
- the liquid pump and the evacuation pump may be gauged, and if the assembly includes heat sink means which include a heat pump this latter can also be gauged to the liquid pump.
- Use of a liquid pump allows operation of assemblies in accordance with the invention to be independent of orientation and minimises the bulk of the fluid transfer ducts.
- heat sinks may be suitable for use in the heat pipe assembly. Examples include the air blown wick assisted condenser system (ABWACS) described in copending UK Patent Application 8129027, the heat pump arrangement described in copending UK Patent Application 8129023, a thermoelectric heat sink of the type described in copending UK Patent Application 8129052, and heat sinks described in copending UK Patent Application 8129022, inter alia.
- ABSACS air blown wick assisted condenser system
- thermoelectric heat sink If a thermoelectric heat sink is used the hot face thereof may be bonded directly to the heat pipe at a location designated as the condenser, which location includes a liquid collector for supplying the distributor, perhaps via a pump.
- the liquid may be water. If however freon is employed a higher pressure (lower vacuum) may be permitted within the assembly.
- the thermal conditioning garment shown in figure 1 is a poncho style undergarment 10 shaped to overlie the shoulders of a person. It comprises plastics structure 20 supporting a perforated wick sheet 21 and surrounded by a non-rigid, impermeable plastics envelope 22. The structure 20 provides a continuous void behind the wick 21 and coextensive therewith. The garment carries an umbilical heat transfer lead 23 leading to a connector PEC. The garment is therefore substantially similar in construction to that described in UK Patent Specification 8106782.
- the garment is constructed as a heat receiver element, so that the umbilical lead 23 is arranged for the conveyance of cool liquid to and vapour from the garment.
- the garment and lead 23 contain liquid distribution means in the form of a flexible plastics tube 24 leading from the lead 23 up one side of the garment, across the shoulders and around the neck of the garment.
- the tube 24 is slit in a substantially uppermost location. Edges 25 of the wick 21 are held in the slits by thread 26 sewn through the wicks and passed around the tube 24.
- Figure 1 also illustrates in block form a servicing unit suitable for use with the garment 10. It comprises a liquid pump 31, a motor MPU, a compressor 32, an evacuator 33, an air blower pump 34, and a condenser unit ABWACS with a water reservoir 35.
- a liquid duct 40 connects the condenser ABWACS with the connector PEC via the pump 31, and a vapour duct 41 connects the condenser with the connector via the compressor 32. From the duct 41 between the condenser and the compressor a duct 42 leads to the evacuator 33, while the blower 34 communicate with the sink via a duct 43.
- the motor MPU is arranged for driving the pump 31, the compressor 32, the blower 34 and the evacuator 33 intermittently.
- the pump 31 is a peristaltic pump to preserve ducting integrity, and serves as a non-return valve to the heat sink ABWACS.
- the compressor 32 serves partially to condense and to raise the temperature of the vapour to facilitate operation of the heat sink ABWACS, and is more particularly described in the copending UK Patent Application 8129023.
- the evacuator 32 is employed initially to evacuate the assembly and serves by intermittent operation to maintain a low pressure regime within the assembly. It is particularly described in copending UK Patent Application 8129028.
- the air blower 34 and the reservoir 35 associated with the heat sink ABWACS are more particularly described in the copending UK Patent Application 8129027.
- the connector PEC includes valves by which the garment 10 is isolatable, so that it can be supplied for use already outgassed and perhaps partially evacuated.
- the assembly is prepared for use by being connected as described and shown, when the connector PEC automatically establishes communication between ducts 24 and 40 etc, the poncho donned by someone about to enter a hot environment, and the heat sink ABWACS and the reservoir 35 charged with water.
- the motor MPU is switched on when the environment to the garment wearer has become hot.
- the pump 31 pumps water from the sink ABWACS via the ducts 40 and 24 into the garment 10 and the compressor 12, by compressing the vapour it receives from the garment via the duct 41, raises the temperature thereof while passing it to the sink ABWACS.
- the vapour In the sink ABWACS the vapour is condensed and the water so formed cooled.
- the evacuator 33 operates intermittently to maintain the evacuated state of the assembly interior.
- the liquid upon reaching stations II and III - the liquid is absorbed from the tube 24 into the wick 21 and is distributed therethrough. As the liquid is vapourised by heat from the body the vapour is conveyed via the structure 20 and the leads 23 and 41 to the compressor 32.
- Garments in accordance with the invention may be worn by personnel working in hot environments, such as military personnel, particularly tank crew and aircrew, and furnace operatives. They may be particularly useful in the aircrew context, for in the event of emergency egress over sea the connector PEC, which may be part of an ejector seat mounted personal equipment connector, may be arranged both to isolate the interior of the garment and to minimise the extent to which it and the lead 23 can act as a heat sink per se.
- the heat sink illustrated in figure 4 is substantially that described in UK Patent Specification 1376604. It comprises a pressure vessel 50 with a tight-fitting screw-on cap 51. A coil 52 at the bottom of the vessel, has an inlet end connected by a pipe 53 to a connector PEGs and an outlet end connected by a pipe 54, via a liquid reservoir and air trap 55 and a pump 56 to the connector PECs.
- An adjustable valve 57 is connected across the pipe 54 upstream of the reservoir 55 and downstream of the pump 56.
- the vessel has a relief valve 58, set to a pressure of about 80 psia, in the cap 51 thereof, while a pipe 59 connected to the cap 51 communicates the interior of the vessel with the pump 56.
- the pump is arranged initially to evacuate the assembly.
- the reservoir 55 is primed with a suitable coolant liquid, such as dimethyl silicone and, with the cap 51 off, the vessel 50 is filled with solid carbon dioxide, and the cap 51 tightly replaced.
- a suitable coolant liquid such as dimethyl silicone
- a stage will be reached when all the solid carbon dioxide has disappeared, leaving only the liquid and gaseous phases.
- the cooling unit will still operate efficiently, but the pressure in the vessel 50 will rise and some carbon dioxide gas may escape through the relief valve 58.
- Temperature control of the garment 20 can be effected by adjustment of the valve 57 to vary the volume of liquid by-passing the garment.
- the thermal reservoir illustrated in figure 5 comprises a liquid source 60 and a distinct vapour sink 61.
- the liquid source 60 is connected via a pump 62 and a duct 63 with the connector PECs, which is also connected via a vapour duct 64 with the sink 61.
- the source 60 is charged with a suitable quantity of water, and the sink 61 is filled with dried zeolite.
- the expression 'PEC' employed to indicate the connector in figures 2, 5 and 6, is that normally used to describe the connector means on an ejector seat by which various services, eg oxygen and intercom, are conveyed to an aircrewman.
- the PEC which stands for Personal Equipment Connector, may have three parts; the aircraft connector, the seat mounted element, and the aircrewman connector, arranged so that the aircraft/seat connection is separated upon ejection and the seat element arranged to convey oxygen to the aircrewman from a seat mounted source until seat/man (aircrewman/seat element) separation.
- the triple connector may readily be arranged not just as a normal connector/interchange heat exchanger for the thermal conditioning means of the present invention but in addition to allow or prevent as required during the said man/seat attachment stage of an ejection, normalisation of the pressure within the thermal conditioning garment to restrict the flow of body heat to the sea for example.
- the first heat exchanger need not be a garment and need not be for personal thermal conditioning, and as a garment need not be exclusively for aircrew use, certainly not only those in ejector seats.
- An advantage of apparatus such as that described with reference to figures 4 or 5 is that it does not require an external power source, and can be portable to a place of work so as to permit an operative to work in a hot environment for periods larger than he would otherwise have been able.
- the assembly shewn in figure 6 comprises a latent heat storage (glycerol) reservoir 70 incorporating a working fluid heat exchanger 71, a cabin air inlet heat exchanger 72, a pump 73, and control means including a mixing valve 74, a thermostat 75, and a 2-way valve 76.
- a coupling 77 connects the apparatus with a garment 78 in heat pipe form as worn by an aircrewman in an aircraft cockpit.
- the mixing valve 74 includes a pressure relief valve, not shown.
- the cabin air inlet heat exchanger 72 comprises a coiled liquid duct 80 having fins 81 and sited in an air inlet duct 82.
- the output of the pump 73 is connected via the 2-way valve 76, the tube 80 in the air inlet heat exchanger 72, the reservoir heat exchanger 71, the thermostat 75, the mixing valve 74, the coupling 77, the garment 78 and back to the coupling, the valve 74 and the pump.
- the second output of the valve 76 is connected to the input of the heat exchanger 71.
- the output of the pump 73 is also connected to the thermostat 75 and to the valve 74, and the pressure relief valve in the mixing valve 74 is arranged to permit return flow to the pump when the garment 78 is blocked.
- the working fluid of the apparatus is a water glycerol mixture having a melting point of about 16°C; that of glycerol is about 20°C.
- the garment can be supplied to its wearer with its working fluid pre-frozen to about 10 0 C 7 and this can supply cooling to him for a preliminary standby period prior to flight.
- valve 76 will cause circulating fluid to by-pass the air inlet heat exchanger 72 and be cooled in the heat exchanger 71 by frozen glycerol in the reservoir 70.
- the heat sink shown in figure 7 comprises a cylindrical chassis 90 housing the components of a vapour compression unit, viz a compressor 91, a condenser 92, an expansion valve 93 and an evaporator 94. It also includes a brushless motor 95, a fan 96, insulation means 97 for thermally insulating the evaporator from the condenser and a liquid pump 98.
- a vapour compression unit viz a compressor 91, a condenser 92, an expansion valve 93 and an evaporator 94. It also includes a brushless motor 95, a fan 96, insulation means 97 for thermally insulating the evaporator from the condenser and a liquid pump 98.
- the condenser 92 is in the form of a coil of finned tubing and surrounds the insulant 97 and the evaporator 94.
- the fan 96 for which the chassis acts as a shroud, is arranged for causing air to flow past the condenser fins.
- the motor 95 is arranged to drive the fan 96, the compressor 91, and the pump 98, the compressor and the motor being mounted in and spaced from the chassis 90 by means of mounting air guide vanes 99.
- the expansion valve 93 comprises a coiled capillary tube.
- the vapour cycle circuit connections are not illustrated, and are partly outside the chassis. The order of the circuit is as shown in figure 8, compressor, evaporator, expansion valve, condenser, compressor.
- the heat pipe assembly illustrated in figure 8 comprises a vapour compression cycle heat sink 100 which is as shown in figure 7 but without a pump 98 therein, a heat exchanger 101 located in the cabin air inlet, a pump 102, a control valve 103 with an associated inlet selector 104, and a coupling 105 associated with a garment 106 in heat pipe form.
- the heat exchanger 101 comprises a coiled finned tube located in the air inlet.
- the heat sink 100, with the valve 103 and the pump 102 are located in a ventilated bay in the vicinity of the cockpit.
- the connections of the circuit are as follows.
- the output of the pump 102 is connected to the control valve 103 which now has three outlets, one connected to the input of the heat exchanger 101, one to the input of the evaporator 94, and one to the input of the coupling 105.
- the output of the heat exchanger 101 is also connected to the input of the evaporator 94, and the output of the evaporator 94 is also connected to the input of the coupling 105.
- the operation of the assembly is as follows. On occasions such as during standby, that is when the pilot is seated within his aircraft on the ground and not receiving cool air via the cabin air inlet, the heat exchanger 101 thereof is bypassed and cooling of the liquid in the garment circuit obtained from the unit 100. Modification of the temperature of the garment liquid circuit is obtained by allowing an amount of liquid returning from the garment to by-pass the unit 100.
