Patent number: 10378825Abstract: Provided are a heat exchanger apparatus and a heat source unit that are for use in a chiller unit. The heat exchanger apparatus comprises at least one heat exchanger module (100). The heat exchanger module (100) comprises two heat exchanger units (10 and 20) that are oppositely fitted with each other. At least one between the two heat exchanger units (10 and 20) is bent so that an angle between adjacent two edges (c and d) on at least one extremity of the two heat exchanger units (10 and 20) is less than an angle between main parts (12 and 22) of the two heat ex-changer units (10 and 20), thus increasing the area for heat exchange.Type: GrantFiled: February 12, 2015Date of Patent: August 13, 2019Assignee: Danfoss Micro Channel Heat Exchanger (Jiaxing) Co., Ltd.Inventors: Jing Yang, Yang Xu, Jeffery Lee Tucker, Liuxiang Liu

Patent number: 10274261Abstract: A heat exchanging board (1) and a board-type heat exchanger provided with the heat exchanging board (1). The heat exchanging board (1) comprises a board main body (11). Multiple recessed portions (12) and multiple raised portions (13) are disposed on the surface of the board main body (11). The multiple recessed portions (12) and the multiple raised portions (13) are disposed in a staggered manner along a first direction (S1) and are disposed in a staggered manner along a second direction (S2) perpendicular to the first direction (S1). Top portions of the multiple raised portions (13) are provided slender forms along the first direction (S1). The heat exchanging board (1) and the board-type heat exchanger provided with the heat exchanging board (1) can ensure good strength of the heat exchanger in the case of ensuring the heat exchanging efficiency, and can reduce manufacturing cost of the heat exchanging board (1).Type: GrantFiled: January 14, 2015Date of Patent: April 30, 2019Assignee: Danfoss Micro Channel Heat Exchanger (Jiaxing) Co., LtdInventors: Wenjian Wei, Zhifeng Zhang, Iztok Golobic

Patent number: 10254054Abstract: A heat exchanger and an integral sealing device (100, 200, 300, 400, 500) used for a manifold (10, 10?) in the heat exchanger. The manifold (10, 10?) on one side of the heat exchanger includes two pipelines (11, 12, 11?, 12?) which are parallel to each other and communicated with each other. A first bore (13) and a second bore (14) are formed in two pipelines (11, 12, 11?, 12?) due to a drilling process. The first bore (13) is used for enabling refrigerant to flow from a cavity of one of two pipelines (11, 12, 11?, 12?) into a cavity of the other pipeline. The second bore (14) is a process hole left by the drilling process, and the integral sealing device (100, 200, 300, 400, 500) seals the process hole.Type: GrantFiled: May 8, 2015Date of Patent: April 9, 2019Assignee: DANFOSS MICRO CHANNEL HEAT EXCHANGER (JIAXING) CO., LTD.Inventors: Junfeng Jin, Jing Yang, Yandong Tang, Huan Jin

Patent number: 10082343Abstract: Disclosed are a fin (1) for a heat exchanger, and a heat exchanger having the fin (1). The fin (1) comprises a fin body (10) in a waveform structure formed by boards, wherein the fin body (10) has two first side surfaces (11) which are opposite one another in a first direction, two second side surfaces (12) which are opposite one another in a second direction, and wave crests and wave troughs, which are on the second side surfaces (12); and the first direction and the second direction intersect. The fin body (10) comprises: a first concave portion (13), wherein the first concave portion (13) is formed in the fin body (10), and is located on the two first side surfaces (11) of the fin body (10). The fin (1) and the heat exchanger are manufactured more simply. Since the connection portions between the wave crests and wave troughs of the fin (1) are approximately perpendicular to a heat exchange tube (2), the condensed water is more easily discharged.Type: GrantFiled: July 16, 2015Date of Patent: September 25, 2018Assignee: Danfoss Micro Channel Heat Exchanger (Jiaxing) Co., Ltd.Inventors: Junfeng Jin, Jing Yang, Jeffrey Lee Tucker, Jianlong Jiang, Xiangxun Lu, Hongbing Chen
