Patent number: 11460129Abstract: A method and system are described for a refrigerant distributor, and for attaching the distributor tubes to an evaporator coil. A short tube can inserted into the bell end of a tube and the hell end can be crimped around the short tube to lock it into place. The short tube preferably has a bead or widened shaft around which to crimp the bell. The disclosure is particularly beneficial for aluminum based components because aluminum is more susceptible to blockages or leaking due to problems from brazing.Type: GrantFiled: August 27, 2020Date of Patent: October 4, 2022Assignee: Advanced Distributor Products LLCInventors: Dae-Hyun Jin, Timothy Orr, James Timbs

Patent number: 6698508Abstract: A fin and tube type heat-exchanger having a plurality of 6 mm or smaller heat tubes to allow refrigerant to move therein includes a plurality of cooling fins arranged at predetermined intervals, each cooling fin having a number of joint holes arranged in one or more stages, and a number of slits between the joint holes formed on each stage. Each slit has a projecting segment with an open portion corresponding to the direction of air flow and a pair of standing segments formed at both sides of the projecting segment for guiding the direction of air flow. The projecting segments project in the same direction from the surface of each cooling fin, and the slits are grouped in five rows. The heat tubes pass through and are jointed with the joint holes, respectively. The heat exchanger reduces pressure loss, optimizes heat-exchange efficiency, reduces manufacturing costs, and adapts to alternative refrigerants.Type: GrantFiled: April 4, 2003Date of Patent: March 2, 2004Assignee: LG Electronics Inc.Inventors: Dae Hyun Jin, Byeong Chul Na

Patent number: 5495346Abstract: An element generator for a dither matrix comprises a logic device which receives a row address and a column address and performs a logic operation thereon so as to produce a dither element corresponding to the row address and the column address, which is implemented at low cost and has an advantage in that the processing speed is increased. The dithering apparatus comprises a dither-matrix element generator, a comparator, an adder and a selector. The comparator compares the output of the dither-matrix element generator with lower-bit data of the original image data. The adder adds a predetermined number to upper-bit data of the original image data. The selector selects one between the upper-bit data and the adder output, in accordance with the output of the comparator, so as to produce the selected one as the dithered image data. Dithering is thereby performed via hardware, which leads to an increased processing speed.Type: GrantFiled: July 7, 1994Date of Patent: February 27, 1996Assignee: Samsung Electronics Co., Ltd.Inventors: Byung-kyun Choi, Kil-su Eo, Dae-hyun Jin
