The present invention relates to a heat exchanger for a refrigerator vehicle and a manufacturing method thereof to enable an efficient heat exchange between a first coolant having a low temperature and a high pressure and a second coolant having a high temperature and a low pressure in the heat exchanger. According to the present invention, the heat exchanger comprises a tubular pipe, a coil pipe, a first coolant inlet pipe, a first coolant outlet pipe, a second coolant inlet pipe, and a second coolant outlet pipe. The tubular pipe has a shape with both sides opened, to form an inner space by press-processing the both sides, with one side formed with a first coolant inlet to receive the low temperature and high pressure first coolant and a second coolant outlet to discharge the high temperature and low pressure second coolant, and with the other side formed with a first coolant outlet to discharge the first coolant and a second coolant inlet to receive the second coolant. The coil pipe of a spiral shape is placed inside the tubular pipe. The first coolant inlet pipe is connected to one side of the coil pipe to protrude outward from the first coolant inlet. The first coolant outlet pipe is connected to the other side of the coil pipe to protrude outward from the first coolant outlet. The second coolant inlet pipe is connected to the second coolant inlet to protrude outward from the tubular pipe. The second coolant outlet pipe is connected to the second coolant outlet to protrude outward from the tubular pipe.
본 발명은 냉동 탑차용 열교환기 및 그 제조 방법에 관한 것으로, 열교환기 내부공간에서 저온고압의 제1 냉매와 고온저압의 제2 냉매의 열교환이 효율적으로 이루어 질 수 있게 하기 위한 것이다. 본 발명에 따른 냉동 탑차용 열교환기는 튜브관, 코일관, 제1 냉매입구관, 제1 냉매출구관, 제2 냉매입구관 및 제2 냉매출구관을 포함한다. 튜브관은 양측이 개방된 관형태로, 양측을 프레스 가공하여 내부공간을 형성하고, 일측에 저온고압의 제1 냉매가 유입되는 제1 냉매입구와 고온저압의 제2 냉매가 유출되는 제2 냉매출구를 형성하고, 타측에 제1 냉매가 유출되는 제1 냉매출구와 제2 냉매가 유입되는 제2 냉매입구를 형성한다. 코일관은 튜브관의 내부 공간에 위치하는 나선형으로 형성된다. 제1 냉매입구관은 코일관의 일측과 연결되어 튜브관의 제1 냉매입구 외부로 돌출된다. 제1 냉매출구관은 제1 냉매입구관의 타측에 연결되어 튜브관의 제1 냉매출구 외부로 돌출된다. 제2 냉매입구관은 제2 냉매입구과 연결되어 튜브관의 외부로 돌출된다. 제2 냉매출구관은 제2 냉매출구과 연결되어 튜브관의 외부로 돌출된다.
