Patent number: 11067340Abstract: A heat exchanger and a method for manufacturing the same provides a double pipe heat exchanger including an outer pipe, an inner pipe forming a first fluid passage and a second fluid passage between the inner pipe and the outer pipe, first and second connecting pipes to pass fluid from the outside and exhaust the fluid by connecting ends of the outer pipe, and a connector to connect the inner pipe and each connecting pipe to the outer pipe. The connector includes expanded ends of the outer pipe and a reducing part configured to assemble the inner pipe inserted in the outer pipe with an end of each connecting pipe by forming at an end of each expanding part with a pressing process. The center line of the inner pipe connected to the connector is disposed at an upper side of the inner circumference surface of the outer pipe.Type: GrantFiled: April 18, 2019Date of Patent: July 20, 2021Assignee: HS R & A CO., LTDInventors: Jongkang Lee, Byeongki Kang, Deokhyun Lim, Youngjun Kim, Jiseung Ryu

Patent number: 10371453Abstract: A double pipe heat exchanger and a method of manufacturing the same are provided. The double pipe heat exchanger including an outer pipe and an inner pipe having a first flow channel therein and having an outer diameter smaller than an inner diameter of the outer pipe and inserted into the outer pipe to form a second flow channel between the inner pipe and the outer pipe includes a plurality of first grooves formed in a spiral shape in a lengthwise direction at an outer circumferential surface of the inner pipe to enable the second flow channel to have at least partially a spiral shape and at least one second groove each formed in a portion between two first grooves adjacent to an outer circumferential surface of the inner pipe and formed along the first groove.Type: GrantFiled: May 2, 2017Date of Patent: August 6, 2019Assignee: HS R & A CO., LTDInventors: Jongkang Lee, Byeongki Kang, Deokhyun Lim, Youngjun Kim, Jaewon Sim

Patent number: 9513061Abstract: A dual pipe and a heat exchanger comprises: an outer pipe formed separately from the inner pipe to house the inner pipe therein; and a connector coupled to the inner pipe and the outer pipe. The connector includes: an outer pipe connection portion for housing an end portion of the outer pipe therein; a fastening groove; a stopper; and a through hole. The inner pipe is housed at the inside of the outer pipe, and a coil portion is formed in a portion positioned at the inside of the outer pipe. A portion extended from the coil portion is extended from the inside to the outside of the connector through a through hole of the connector. An outermost portion of the coil portion line contacts with an inner circumferential surface of the outer pipe.Type: GrantFiled: September 5, 2013Date of Patent: December 6, 2016Assignee: HS R & A Co., Ltd.Inventors: Jaehyeok Choi, Gukhyun Kim, Deokhyun Lim, Youngjun Kim
