Heat Exchanger-te hnathawh dan bulpui (Detailed Breakdown) 1.1.
1. Heat Transfer chungchanga dan bulpui: Mahni insiamthatna (Spontaneous Heat Transfer) atana tehfung
Heat exchanger hnathawh hian thermodynamics dan pakhatna leh pahnihna chu khauh takin a zawm a, chungte chu hmanrua hnathawhna atana theoretical basis bulpui ber a ni.Heat hian physical property a nei a, chu chu temperature sang-temperature object atanga low-temperature object-a a luang chhuak thei a, he transfer process hi fluid media pahnih temperature-in dynamic equilibrium a thlen thlengin temperature danglamna chu zero a hnaih thlengin a kal zel a ni.In actual industrial operations, heat exchange efficiency tihchangtlun leh operating conditions tihhlawhtlin nan, pawn lam thiltihtheihna (pump-te fluid flow khalhtu leh heat exchange structures tihchangtluntu ang chi) te hi heat transfer ti chak turin an hmang tlangpui.It breaks the natural equilibrium state to achieve continuous, efficient, and directional heat exchange, meet the continuous operation needs of industrial production.
2. Core heat transfer method pathum (process chhung zawnga thawhhona tha tak nei) .
Heat exchanger chhunga heat transfer hi thil pakhat chauh ni lovin, conduction, convection leh radiation te inzawmkhawm a ni zawk. Process tinte proportion hi hnathawh dan azirin a inang lo va, heat exchange tha tak neih theih nan thawhhona tha tak neih a ni. A thu bul bik chu hetiang hi a ni:
(1) Heat conduction: lumna inthlak danglamna atana core bridge
Heat conduction hi heat exchanger-a heat transfer method bulpui ber leh a bulpui ber a ni a, media lum leh vawt inkara heat exchange-na kawng pawimawh ber a ni bawk.Fluid lum leh vawt te hi thermal conductivity sang tak nei solid wall hmanga inthen a ni (common materials ah chuan stainless steel, carbon steel, copper alloy, titanium alloy, leh export-a hman thin mainstream heat exchange material dangte pawh a tel).The heat from the high-temperature fluid chu molecular thermal motion hmangin solid heat exchange wall-ah dah hmasak a ni a, chumi hnuah wall-a high{3}}temperature lam atanga low-temperature side-ah kalpui a ni a, a tawpah chuan low-temperature fluid-ah transfer a ni.He process pumpui hian large-scale fluid flow a mamawh lo heat transfer hi medium molecule inkara inzawmna hmanga tih theih a ni. Heat exchange wall-a thermal conductivity, thickness leh material hian direct-in heat transfer efficiency bulpui a hril a ni.
(2) Heat convection: Heat exchange efficiency tihchangtlunna kawng pawimawh tak
Thermal convection hi natural convection leh forced convection-ah then a ni a, industrial heat exchanger-te heat exchange efficiency tihchangtlunna atana hmanraw bulpui ber a ni. Natural convection chu temperature danglamna avanga density danglamna avanga fluids spontaneous flow a ni a, chu chuan heat transfer a tichak a ni.Forced convection hian pawn lam power equipment pump leh fan te hmangin fluid chu heat exchange wall chu speed sang takin a tlanpui a, wall-a heat transfer boundary layer chu a tichhia a, heat transfer resistance nasa takin a tihtlem a, chu chuan fluid atanga wall-ah heat transfer a phalsak a, chutah chuan heat transfer a phalsak a ni wall atanga a lehlamah fluid thlengin rang zawkin.Ram dang sumdawnna atana thawn chhuah high{3}}efficiency heat exchanger tam zawk chuan ram pawn lama customer-te high{4}}capacity leh high-efficiency production mamawh phuhruk nan forced convection design an hmang thin.
(3) Thermal radiation: temperature sang-temperature sang tak hnuaia heat transfer supplementary
Thermal radiation hi non-contact heat transfer method a ni a, medium emaw solid wall emaw a innghat lo. High-temperature fluid-te hian electromagnetic wave angin pawn lamah direct-in heat energy an pe chhuak a, chu chu low-temperature fluid-te chuan an la lut a, heat conversion chu an ti zo ta a ni.Hetiang heat transfer chi hi temperature pangngaiah chuan percentage tlemte chauh a ni a, ngaihthah theih a ni.Amaherawhchu, high-temperature heat exchange scenario-ah (asuch as high-temperature flue gas heat exchange, metallurgical support, leh high-temperature chemical reactions), thermal radiation chu auxiliary heat transfer method pawimawh tak a lo ni ta a, hei hian heat exchange effect pumpui a tichangtlung lehzual a ni. Hei hi high-end industrial heat exchanger-te ngaihtuah ngai heat transfer factor a ni bawk.
Core Structure Hnathawh dan: Isolated Continuous Heat Exchange
Export market-a mainstream shell-leh-tube, plate, leh finned heat exchanger hralh chhuah tam zawk chuan isolated structural design an hmang a.He hmanrua hi heat exchange tube bundle, heat exchange plate, leh sealing gasket ang chi component hrang hrang hmangin independent medium flow channel pahnih emaw a aia tam emaw-ah then a ni. Fluid lum leh vawt te hi an channel hrang hrangah kawng khatah emaw, kawng hrang hrangah emaw an luang chhuak a ni.Hetiang hian media mixing a awm lo va, cross-contamination a awm lo. Heat hi intermediate solid heat exchange wall kaltlangin directionally transfer a ni a, fluid luang chhunzawm zel nen chuan uninterrupted, stable leh controllable heat energy exchange a awm thei a ni.He structure hian heat exchange efficiency a tichiang a, special fluid media hrang hrang, corrosive, flammable, explosive, leh clean fluids te tan pawh a insiamrem thei a, ram pawna industry hrang hrangte hnathawh dan a phuhruk thei a ni.
