Abstract: front page image
(EN) The present invention relates to a plate heat exchanger for largely improving heat exchange efficiency by improving the flow of fluids. The plate heat exchanger of the present invention comprises a plurality of heat exchange tubes stacked in the vertical direction, each formed by coupling upper and lower plates with each other, and each having a 1st flow channel in which a 1st fluid flows, and a 2nd flow channel formed between the heat exchange tubes for the flow of a 2nd fluid, wherein each of the heat exchange tubes has an inlet path and an outlet path separated from each other on both ends, the upper plate has an upper flange protruded from the upper parts of the inlet path and the outlet path, the lower plate has a lower flange protruded from the lower parts of the inlet path and the outlet path, a plurality of upper flow grooves are extended in an oblique direction on the bottom surface of the upper plate, a plurality of lower flow grooves are extended in an oblique direction on the top surface of the lower plate, the upper plate and the lower plate form the first flow channel by being coupled with each other in such a manner that the upper flow grooves and the lower flow grooves intersect each other, and in the periphery of the inlet path and the outlet path of the upper plate and in the periphery of the inlet path and the outlet path of the lower plate are provided structures for guiding the flow of the fluids in two or more directions.
(FR) La présente invention concerne un échangeur thermique à plaques permettant d'accroître considérablement le rendement d'échange thermique en améliorant l'écoulement des fluides. L'échangeur thermique à plaques de cette invention comprend une pluralité de tubes d'échange thermique empilés dans le sens vertical, chacun étant formé par couplage des plaques supérieure et inférieure entre elles, et chacun comportant un premier canal d'écoulement dans lequel s'écoule un premier fluide et un deuxième canal d'écoulement formé entre les tubes d'échange thermique pour l'écoulement d'un deuxième fluide. Chacun des tubes d'échange thermique possède une voie d'admission et un voie d'évacuation séparées l'une de l'autre aux extrémités, la plaque supérieure ayant un rebord supérieur faisant saillie des parties supérieures de la voie d'admission et de la voie d'évacuation, et la plaque inférieure ayant un rebord inférieur faisant saillie des parties inférieures de la voie d'admission et de la voie d'évacuation. Une pluralité de rainures d'écoulement supérieures s'étendent dans un sens oblique sur la surface inférieure de la plaque supérieure; une pluralité de rainures d'écoulement inférieures s'étendent dans un sens oblique sur la surface supérieure de la plaque inférieure, la plaque supérieure et la plaque inférieure formant le premier canal d'écoulement par leur couplage entre elles de telle sorte que les rainures d'écoulement supérieures et les rainures d'écoulement inférieures se croisent; et, dans la périphérie de la voie d'admission et de la voie d'évacuation de la plaque supérieure et de la plaque inférieure sont formées des structures pour guider l'écoulement des fluides dans au moins deux directions.
(KO) 본 발명은 유체의 유동성을 향상시킴으로써 열교환효율을 대폭 향상시킬 수 있는 플레이트 열교환기에 관한 것으로, 개시된 본 발명의 플레이트 열교환기는 상하방향으로 적층된 복수의 열교환튜브를 포함하고, 각 열교환튜브는 상부 플레이트 및 하부 플레이트가 상호 결합됨으로써 형성되며, 상기 각 열교환튜브는 그 내부에 제1유체가 유동하는 제1유동채널을 가지며, 상기 열교환튜브들 사이에는 제2유체가 유동하는 제2유동채널이 형성되며, 상기 각 열교환튜브는 그 양단에 이격된 유입통로 및 유출통로를 가지고, 상기 상부 플레이트는 상기 유입통로 및 유출통로의 상부에서 돌출된 상부 플랜지를 가지며, 상기 하부 플레이트는 상기 유입통로 및 유출통로의 하부에서 돌출된 하부 플랜지를 가지고, 상기 상부 플레이트의 저면에는 복수의 상부 유동홈이 사선방향으로 연장되고, 상기 하부 플레이트의 상면에는 복수의 하부 유동홈이 사선방향으로 연장되며, 상기 상부 플레이트 및 하부 플레이트는 상기 상부 유동홈 및 하부 유동홈이 서로 교차하도록 결합됨으로써 제1유동채널을 구성하며, 상기 상부 플레이트의 유입통로 및 유출통로 주변과 상기 하부 플레이트의 유입통로 및 유출통로 주변에는 유체의 흐름방향을 2 이상으로 유도하는 구조를 가지는 것을 특징으로 한다.
