Abstract
一種用於熱交換器的流道結構，係以複數個空心多面體的結構單元連續設置於上板與下板之間所構成。 A flow path structure for a heat exchanger is constructed by continuously arranging a plurality of hollow polyhedral structural units between an upper plate and a lower plate.
Description
本發明係有關一種流道結構，尤指為一種用於熱交換器的流道結構。 The present invention relates to a flow path structure, and more particularly to a flow path structure for a heat exchanger.
傳統熱交換器之流道容易受到流體腐蝕，而造成流道受損甚至破裂，使得傳統熱交換器存在耐用性不佳與壽命不長等缺點。 The flow path of the conventional heat exchanger is easily corroded by the fluid, and the flow path is damaged or even broken, so that the conventional heat exchanger has the disadvantages of poor durability and short life.
若為提高前述熱交換器的耐用度與使用壽命，須進一步地在熱交換器之流道中使用抗腐蝕金屬，以避免流道受到流體腐蝕的影響，進而提高熱交換器的耐用度與使用壽命。 In order to improve the durability and service life of the aforementioned heat exchanger, it is necessary to further use corrosion-resistant metal in the flow passage of the heat exchanger to avoid the influence of fluid corrosion on the flow passage, thereby improving the durability and service life of the heat exchanger. .
然而，在熱交換器之流道中使用抗腐蝕金屬雖可避免流道不受到流體腐蝕的影響，但相對的，使用抗腐蝕金屬卻會提高熱阻，進而降低熱傳導性能。 However, the use of corrosion-resistant metals in the flow path of the heat exchanger avoids the flow path from being affected by fluid corrosion, but the use of corrosion-resistant metal increases the thermal resistance and thus the thermal conductivity.
因此，如何克服上述習知技術之問題，實已成目前亟欲解決的課題。 Therefore, how to overcome the above-mentioned problems of the prior art has become a problem that is currently being solved.
