Heat exchanger unit te heat transfer efficiency hi engtin nge kan tih that theih ang?

Heat exchanger hnathawh dan tur: Fluid medium chu heat exchanger chhunga corrugated gaps kal tlangin flow rate hniam takah a luang a, chu chuan turbulent flow a siam a, chu chuan heat transfer coefficient sang tak a siam thei a ni. Heat transfer efficiency hi heat exchanger chhunga corrugated plate awm dan leh a structure leh fluid flow state nen a inzawm tlat a ni tih kan thutlukna siam thei. Heat exchanger-a heat transfer efficiency tihchangtlun nan eng method bik nge hman theih ang?

Plate chu plate a heat transfer core a ni .Heat Exchanger 1000 a ni.. A thermal conductivity leh flow channel design hian direct takin basic heat transfer capacity a tichiang a, source atanga optimized hmasak a ngai a ni.

1.Plate angin thermal conductivity sang tak nei materials thlang rawh .

Stainless steel 304, 316L stainless steel, copper alloy leh titanium alloy te chu plate atan kan thlang thei a ni. Stainless steel hian thermal conductivity tha tak a nei a, a man pawh a tlawm hle. Strength sang tak a nei a, stamping performance tha tak a nei a, boruak khirh takah pawh awlsam taka oxidized a ni lo.

2.Plate corrugated structure tha tak siam dan tur .

Plate-a corrugation design hian flow channel shape a tichiang a, fluid disturbance nasatna (a disturbance a chak zawk chuan boundary layer a ti hniam a, convective heat transfer coefficient a sang zawk) a nghawng nghal bawk. Corrugation type hi fluid viscosity leh heat transfer mamawh angin thlan tur a ni:

3.Plate Quantity leh Flow Channel Combination te design tha tak a ni.

Plate awm zat hian heat transfer area zawng zawng (A) a hril a, flow channel combination (single-pass/multi-pass) hian fluid flow rate a nghawng a ni. "Heat Transfer Load" angin dik taka inmil a ngai a ni:Plate zat chhiar dan: Formula Q=k×a×ΔTₘ (Q chu heat exchange load a ni a, ΔTₘ chu logarithmic mean temperature danglamna a ni), K value leh ΔTₘ chuan minimum heat transfer area mamawh chu reversely a chhut hnuah. Tichuan, plate pakhata effective area (eg, plate area hman tlanglawn chu 0.1-0.5㎡ a nih chuan) atanga chhut chuan plate awm zat chu chhut la. Hun rei lote chhunga load inthlak danglamna hmachhawn turin 10%-15% margin reserve a tha.

Flow Channel Combination Optimization: Turbulent range-a flow velocity tihpun nan flow paths zat tihpun emaw tihtlem emaw (Plate flow path-ah chuan RE > 300 a tha). Flow velocity a hniam lutuk (entir nan, flow path pakhata re=150, laminar flow), "two-flow path" (plate-a fluid a luang leh chhuak, path leh flow velocity pahnih, leh 300 thlenga tihpun, chutiang chuan turbulent flow-a lut tur).

4.Plate-te thickness chu tihtlem la, . Heat exchanger unit 1000 a ni.

Plate thickness ngei hian thermal conductivity nasa takin a nghawng a ni. Research experiment-ah chuan symmetrical plate heat exchanger-ah chuan plate thickness 0.1mm-in a tihhniam apiangin overall heat transfer system chu 600W-in a tipung thei a, asymmetrical device-ah erawh chuan 500W-in a pung thei tih hmuhchhuah a ni. Chuvangin, heat exchanger-a mechanical performance mamawh phuhrukna tur premise hnuaiah chuan plate thickness design a nih chuan design a ni a, thermal conductivity a sang zawk a ni.

5.Corrugated section a shape .

Compression laiin stress distribution chu corrugated cross-section chu triangular a nih chuan a inang lo hle nachungin, herringbone plate-a heat transfer coefficient, process harsa tak chu a sang zawk a ni. Chu bakah, corrugated design angle a lian chuan plate branch inkar flow channel-a medium flow velocity a sang zawk a, chuvangin heat transfer coefficient a sang zawk ang.

6.Plate-a scale chu a hun takah tifai rawh .

Plate-a scale chu 1mm aia tam a nih chuan, hmanrua zawng zawng heat transfer efficiency chu 10%-in a tlahniam ang. Chuvangin, inlet-ah filtering hmanrua dah belh tur a ni a, heat exchanger pawh tihfai fo tur a ni. Chutiang chauh chuan plate-a scale thickness chu tihtlem theih a ni a, heat exchange efficiency chu relatively level state-ah a stabilise thei bawk.
