Abstract
"TROCADOR DE CALOR". Um trocador de calor, no qual o espaço (110a) em cada um de uma pluralidade de tubos (110) é segmentado por uma parede divisória (111), e covinhas (protuberâncias) (112) são formadas na parede interna dos tubos (110), é descrito. A área transversal substancial do caminho de fluxo, que possui um grande efeito na velocidade do fluxo nos tubos (110), pode dessa forma ser reduzida sem aumentar o número total de tubos (110). Mesmo no caso onde a área de radiação é aumentada pelo aumento do diâmetro longo do tubo (110), portanto, um fluxo turbulento da água de resfriamento pode ser obtido em colaboração com a ação de agitação das covinhas (112). Dessa forma, a redução no coeficiente de transferência de calor entre a água de resfriamento e os tubos (110) pode ser impedida. Como resultado disso, a capacidade de radiação do radiador (100) pode ser aperfeiçoada enquanto suprime o aumento no número de partes e no custo de produção do radiador (100), produzindo dessa forma um radiador adequado para veículos automotores grandes."HEAT EXCHANGER". A heat exchanger, in which the space (110a) in each of a plurality of tubes (110) is segmented by a dividing wall (111), and dimples (protuberances) (112) are formed in the inner wall of the tubes (110 ), is described. The substantial cross-sectional area of the flow path, which has a great effect on the flow velocity in the tubes (110), can thus be reduced without increasing the total number of tubes (110). Even in the case where the radiation area is increased by increasing the long diameter of the tube (110), therefore, a turbulent flow of the cooling water can be obtained in collaboration with the shaking action of the dimples (112). In this way, the reduction in the heat transfer coefficient between the cooling water and the tubes (110) can be prevented. As a result, the radiation capacity of the radiator (100) can be improved while suppressing the increase in the number of parts and the production cost of the radiator (100), thereby producing a radiator suitable for large motor vehicles.
