Abstract
(EN)
Provided is a heat exchanger where a refrigerant tube (16a) and/or a cooling water tube (43a) is stacked, and which comprises heat exchange parts (71, 72) conducting heat exchange between air and a refrigerant and/or cooling water. An air passage (70a) is disposed in a space between the tubes (16a, 43a) where the refrigerant tube and the cooling water tube adjoin each other. In terms of the heat exchange parts provided, the upstream heat exchange part (71) is disposed on the upstream side in the airflow direction, and the downstream heat exchange part (72) disposed on the downstream side of the upstream heat exchange part (71). The ratio of the number of the refrigerant tubes (16a) to the number of all tubes constituting the upstream heat exchange part (71) is different from the ratio of the number of the refrigerant tubes (16a) to the number of all tubes constituting the downstream heat exchange part (72).

L'invention concerne un échangeur thermique où un tuyau de réfrigérant (16a) et/ou un tuyau d'eau de refroidissement (43a) sont empilés, et qui comprend des parties d'échange thermique (71, 72) réalisant un échange thermique entre l'air et un réfrigérant et/ou de l'eau de refroidissement. Un conduit d'air (70a) est disposé dans un espace entre les tuyaux (16a, 43a) où le tuyau de réfrigérant et le tuyau d'eau de refroidissement sont contigus. En termes de parties d'échange thermique constitutives, la partie d'échange thermique en amont (71) est disposée sur le côté en amont dans la direction de flux d'air, et la partie d'échange thermique en aval (72) est disposée sur le côté en aval de la partie d'échange thermique en amont (71). Le rapport du nombre de tuyaux de réfrigérant (16a) sur le nombre de tous les tuyaux constituant la partie d'échange thermique en amont (71) est différent du rapport du nombre de tuyaux de réfrigérant (16a) sur le nombre de tous les tuyaux constituant la partie d'échange thermique en aval (72).

熱交換器は、冷媒用チューブ(16a)および冷却水用チューブ(43a)のうち少なくとも一方のチューブを積層配置して構成されて、冷媒および冷却水のうち少なくとも一方と空気とを熱交換させる熱交換部(71、72)を備える。冷媒用チューブおよび冷却水用チューブの隣り合うチューブ(16a、43a)間に形成される空間に、空気が流通する空気用通路(70a)を形成する。熱交換部として、空気の流れ方向の上流側に配置される上流側熱交換部(71)、および、空気の流れ方向における上流側熱交換部(71)の下流側に配置される下流側熱交換部(72)を設け、上流側熱交換部(71)を構成するチューブの総チューブ本数に対する冷媒用チューブ(16a)の本数割合と、下流側熱交換部(72)を構成するチューブの総チューブ本数に対する冷媒用チューブ(16a)の本数割合とが異なるようにする。
