See figures.1.and.2, it shows the heat exchanger assembly 100 according to embodiment.Heat exchanger assembly 100 comprises the outlet 104 that receives the entrance 102 of liquid coolant and the liquid of output heating.Core 106 comprises the pipe assembly 108 that limits fluid loop.Pipe assembly 108 comprises a plurality of layers 110.According at least one embodiment shown in Fig. 2, pipe assembly 108 has 28 layer 110.Every one deck 110 comprises a plurality of tube channel 112.In at least one embodiment, every one deck 110 comprises three tube channel 112.One or more in tube channel 112 comprise a plurality of port ones 14, and it forms the fluid path extending along the width of tube channel 112, as more detailed discussion below.Air fin 116 can be inserted between every one deck 110 to promote to the heat transmission of flowing through the liquid of tube channel 112.
Tube channel 112 is sent to outlet 104 by liquid coolant from entrance 102.Liquid coolant can comprise the mixture of the water of about 60% propane diols and 40%.Air by air fin 116 and heat exchanger assembly 100 carry out alternately with by heat from transfer of air to liquid coolant, thereby cooling-air.The liquid of heating is flowing through tube channel 112 by three paths of configuration experience with cross-counterflow in exporting 104 processes before leaving.Can from liquid cools loop, remove heat by upstream device.
Referring now to Fig. 3 and Fig. 4, it shows according to the cross-sectional view strength of the tube channel 112 of embodiment.Tube channel 112 comprises body, and it has first surface (for example end face 118) and second surface (for example bottom surface 120).End face 118 and bottom surface 120 extend to limit pipe width between the first and second opposite ends 122,124.In at least one embodiment, tube channel have from approximately 0.995 inch (approximately 2.527 centimetres) be changed to approximately 1.003 inches (approximately 2.548 centimetres) pipe width, from approximately 0.125 inch (approximately 0.318 centimetre), be changed to the pipe height (HT of approximately 0.130 inch (approximately 0.330 centimetre)
tUBE) and the length of tube (L that is changed to approximately 15.0 inches (approximately 38.1 centimetres) from approximately 14.0 inches (approximately 35.56 centimetres)
tUBE).The body of tube channel 112 is made into integration by single Heat Conduction Material (including but not limited to 31104 aluminium) and can for example uses extrusion process and make.The first and second ends 122,124 can comprise the radius of curvature of the crooked nose of final formation 126.External contact is avoided in the end 122,124 that sweep 126 radially extends to support with protection channel pipe from the body of tube channel 112, and also absorbs flowing liquid and be applied to the fluid pressure on end simultaneously.Crooked nose can have the width (W of approximately 0.020 inch (approximately 0.051 centimetre)
eND).
A plurality of port ones 14 be formed through the body of tube channel 112 and be formed on end face 118 and bottom surface 120 between.Each port one 14 extends to carry liquid between the entrance 102 at heat exchanger 100 and outlet 104 along the width of tube channel 112.In one embodiment, port one 14 is approximately square configuration.In at least one embodiment, the bight of port one 14 can be crooked to form the square with fillet.Alternately, port one 14 is that rectangular shape is to limit the ratio of port height and port width.The ratio of port height and port width can be expressed as port height/port width=ratio.In at least one embodiment, the ratio table of port height and port width is shown 0.100 inch/0.0594 inch=1.6835 inches.
In at least one embodiment, curved end 122,124 can limit has semicircular adjacent port 114.Width (the W of semi-circular ends port
sEMICIRC) be approximately 0.0594 inch (0.150876 centimetre).End port has radius of curvature.
Each port one 14 limits the first wall (for example roof 128), the second wall (for example diapire 130) and at least one fin (for example center fin 132).Center fin 132 is formed between each adjacent port 114 and between roof 128 and diapire 130 and extends.Roof 128 and diapire 130 have the height (HT of approximately 0.014 inch (approximately 0.036 centimetre)
tOP, HT
bOTTOM).In at least one embodiment, center fin 132 has the width (W of approximately 0.010 inch (approximately 0.0254 centimetre)
cENTER).Center fin 132 is not limited to above-mentioned width and can has the width that is changed to approximately 0.0115 inch (approximately 0.0292 centimetre) from approximately 0.0085 inch (approximately 0.0216 centimetre).Roof 128, diapire 130He center fin 132 are integral with each other formation.Correspondingly, the size of wall and fin limits the gross thickness of each port one 14.The height of the quantity of wall and fin, the width of port, port, fin thickness, wall thickness and tube material are controlled the speed that is passed to the heat of liquid from the air loop of heat exchanger.That is, can to the parameter modification on the air loop of heat exchanger, change the speed that each in described pipe size (fin thickness, wall thickness, pipe width, port number, port width, port height) is controlled the liquid that flow velocity that heat is added into set flows through by being independent of.Correspondingly, tube channel 112 can be dimensioned to meet systematic function and pressure drop needs.In at least one embodiment, port one 14 has the width (W of approximately 0.0594 inch (approximately 0.150876 centimetre of +/-tolerance)
pORT) and the height (HT of approximately 0.100 inch (approximately 0.254 centimetre of +/-tolerance)
pORT).
A plurality of walls and fin provide heating surface, and it contacts with the liquid that flows through port one 14.Correspondingly, heat is passed to wall and fin and heat is spread out of to tube channel 112 from liquid transfer.Can the quantity based on port one 14 control the pressure of realizing from rate of heat transfer and the heat exchanger 100 of tube channel 112.The quantity (for example: 10 ports are provided) that reduces port one 14 can reduce the secondary heat transfer area of each pipe 112 and reduce fluid-pressure drop, and the quantity (for example: 18 ports are provided) of increase port one 14 can increase secondary heat transfer area and increase fluid-pressure drop.The fluid-pressure drop once providing with secondary surface area and tube channel 112 of quantity that therefore, can be based on port one 14 and the design of corresponding fin and wall thickness, port number, port height and port width and Heat Transfer Control.
