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 a heat exchange chamber of the heat exchanger. According to the present invention, the heat exchanger comprises a first tubular pipe, a second 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 first tubular pipe has a tubular shape with one open side by a spinning process, to form a first inner space, with the other side formed with a first coolant inlet to receive the low temperature high pressure first coolant and a second coolant outlet to discharge the high temperature low pressure second coolant. The second tubular pipe has a tubular shape with one open side by the spinning process to form a second inner space, to be connected to the open side of the first tubular shape, the heat exchange chamber by integrating the first and the second inner spaces, and a first coolant outlet to discharge the first coolant and a second coolant inlet to receive the second coolant in the other side. The coil pipe of a spiral shape is placed in the heat exchange chamber. 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 second tubular pipe. The second coolant outlet pipe is connected to the second coolant outlet to protrude outward from the first tubular pipe.
본 발명은 냉동 탑차용 열교환기 및 그 제조 방법에 관한 것으로, 열교환기의 열교환실에서 저온고압의 제1 냉매와 고온저압의 제2 냉매의 열교환이 효율적으로 이루어 질 수 있게 하기 위한 것이다. 본 발명에 따른 냉동 탑차용 열교환기는 제1 튜브관, 제2 튜브관, 코일관, 제1 냉매입구관, 제1 냉매출구관, 제2 냉매입구관 및 제2 냉매출구관을 포함한다. 제1 튜브관은, 스피닝 공정으로 제조되어 일측이 개방된 관형태로 제1 내부공간을 형성하고, 타측에 저온고압의 제1 냉매가 유입되는 제1 냉매입구와 고온저압의 제2 냉매가 유출되는 제2 냉매출구를 형성한다. 제2 튜브관은 스피닝 공정으로 제조되어 일측이 개방된 관형태로 제2 내부공간을 형성하여 제1 튜브관의 개방된 측과 연결하고, 제1 내부공간과 제2 내부공간이 일체되어 열교환실을 형성하고, 타측에 제1 냉매가 유출되는 제1 냉매 출구와 제2 냉매가 유입되는 제2 냉매입구를 형성한다. 코일관은 열교환실에 위치하는 나선형으로 형성된다. 제1 냉매입구관은 코일관의 일측과 연결되어 제1 냉매입구의 외부로 돌출한다. 제1 냉매출구관은 코일관의 제1 냉매입구관 타측에 연결되어 제1 냉매출구 외부로 돌출한다. 제2 냉매입구관은 제2 냉매입구와 연결되어 제2 튜브관의 외부로 돌출한다. 제2 냉매출구관은 제2 냉매출구과 연결되어 제1 튜브관의 외부로 돌출한다.
