본 발명은 차량의 열관리 시스템에 관한 것으로서, 압축기의 흡,토출측에서의 냉매압력 손실을 줄일 수 있도록 구성함으로써, 압축기 흡,토출측에서의 냉매압력 손실로 인한 압축기의 일량 저하를 방지할 수 있는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 압축기와 고압측 열교환기와 히트펌프모드용 팽창밸브와 수냉식 열교환기와 실외열교환기 및, 서로 간에 병렬로 설치되는 복수의 저압측 열교환기들을 구비하는 냉매순환라인을 포함하는 차량의 열관리 시스템에 있어서, 냉매순환라인의 냉매배관 부분들 중, 압축기의 흡,토출측 냉매배관의 냉매압력에 영향을 주는 적어도 하나 이상의 특정 냉매배관 부분이, 다른 부분에 비해 큰 직경을 갖도록, 특정 냉매배관 부분 직경을 다른 부분보다 증대시킨 직경 증대부를 더 구비한다.

    The present invention relates to a heat management system for a vehicle, and the purpose of the present invention is to prevent a decrease in the work load of a compressor due to refrigerant pressure loss at the suction and discharge sides of the compressor by adopting a configuration that can reduce the refrigerant pressure loss at the suction and discharge sides of the compressor. In order to achieve the purpose, the present invention provides a heat management system for a vehicle, wherein the heat management system comprises a refrigerant circulation line including: a compressor; a high-pressure side heat exchanger; an expansion valve for a heat pump mode; a water-cooled heat exchanger; an outdoor heat exchanger; and a plurality of low-pressure side heat exchangers installed in parallel with each other, and further comprises a diameter increase part in which the diameter of at least one specific refrigerant pipe part that affects the refrigerant pressure of refrigerant pipes on the suction and discharge sides of the compressor among refrigerant pipe parts of the refrigerant circulation line is increased compared to the diameter of the other parts such that the specific refrigerant pipe part has a larger diameter than the other parts.
