PROBLEM TO BE SOLVED: To provide a heat exchanger and a heat pump system, which can reduce a proper refrigerant amount in heating operation by reducing a refrigerant amount accumulated in an outdoor heat exchanger during the heating operation.SOLUTION: A vehicle outside heat exchanger 11 comprises a first header 31 of a hollow shape, a second header 32 of a hollow shape provided opposite to the first header 31, and plural tubes 33 which are provided between the first header 31 and the second header 32 and communicates with the first header 31 and the second header 32. The first header 31 is provided with a partition plate 35 which divides the interior of the first header 31, and the first header 31 is formed with a first opening part 36 on the partition plate 35 side between the upper end of the first header 31 and the partition plate 35. When functioning as an evaporator, a refrigerant is supplied from a lower part side of the first header 31 or the second header 32, and the first opening part 36 works as an outflow port of the refrigerant.SELECTED DRAWING: Figure 2

    【課題】暖房運転時に室外熱交換器で溜まり込んでいる冷媒量を低減し、暖房運転時の適正冷媒量を減らすことが可能な熱交換器及びヒートポンプシステムを提供することを目的とする。【解決手段】車外熱交換器11は、中空状の第1ヘッダー31と、第1ヘッダー31に対向して設けられ、中空状の第2ヘッダー32と、第1ヘッダー31と第2ヘッダー32の間に設けられ、第1ヘッダー31と第2ヘッダー32と連通する複数のチューブ33とを備え、第1ヘッダー31には、第1ヘッダー31の内部を区切る仕切板35が設けられ、第1ヘッダー31には、第1ヘッダー31の上端部と仕切板35の間において仕切板35側に第1開口部36が形成され、蒸発器として機能するとき、冷媒は第1ヘッダー31又は第2ヘッダー32の下部側から供給され、第1開口部36が冷媒の流出口となる。【選択図】図2
