Abstract

DC60 (15/11/47) Evaporators contain at least One evaporator with a pair of headers. Stacking each other in parallel And separated from each other for a while And refrigerant pipes Wide parallel facing forward and back directions, and opposite ends are connected to Each side header Each cooling pipe It is a flat pipe consisting of the left and right walls and the front wall. And behind the position between And connected to the front and rear side edges of the left and right walls and a number of auxiliary walls positioned between and connected to the left wall. And to the right, extending along the length in there, and at the intervals specified between the front walls. And the back wall The flat ducts are parallel to the inside of the refrigerant channel, where the auxiliary wall contains a number of connecting holes. To make a channel Of refrigerant in parallel and connected to each other The smooth pipe consists of a left-like piece. Plate with wall on the left Assemble And the piece on the right Like a plate with the right wall making up the front and rear walls of the smooth pipe, it consists of a wall extending to the right, extending to the right from each side, front and back edge of the included left piece. It is the same piece in there and is wrapped up with the right piece. And the wall extends to the left, extending to the left from Each side, front, and back edge of the right piece is assembled in one place. And cover with the left part The auxiliary wall of each smooth pipe is composed of a composite wall. It is the part that extends in from the wall on the left that make up the left piece. And has an outer end Cover with a wall on the right that forms one piece of another. The evaporator consists of at least One evaporator with a pair of headers. Stacking each other in parallel And separated from each other for a while And refrigerant pipes The wide parallel turns in the front and rear directions, and the opposite end is connected to Each side header Each cooling pipe It is a flat pipe consisting of the left and right walls and the front wall. And behind the position between And connected to the front and rear side edges of the left and right walls and a number of auxiliary walls positioned between and connected to the left wall. And to the right, extending along the length in there, and at the intervals specified between the front walls. And the back wall The flat ducts are parallel to the inside of the refrigerant channel, where the auxiliary wall contains a number of connecting holes. To make a channel Of refrigerant in parallel and connected to each other The smooth pipe consists of a left-like piece. Plate with wall on the left Assemble And the piece on the right Like a plate with the right wall making up the front and rear walls of the smooth pipe, it consists of a wall extending to the right, extending to the right from each side, front and back edge of the included left piece. It is the same piece in there and is wrapped up with the right piece. And the wall extends to the left, extending to the left from Each side, front, and back edge of the right piece is assembled in one place. And cover with the left part The auxiliary wall of each smooth pipe is composed of a composite wall. It is the protrusion from the wall on the left that makes up the left part. And has an outer end Cladding to the wall of the right that forms another piece.

Claims (5)

1. Evaporators (55) consisting of one evaporator unit (55A) with one pair of headers (56, 57) stacked in parallel. And separated for some time, and the parallel tubes of refrigerant (4) wide, facing in the direction from front to back, and opposite ends are connected to the headers (56, 57) each side by refrigerant pipes (4) each pipe is a flat pipe (17) consisting of a smooth left and right wall (11,12) and a front and rear wall (13,14) with The position is between And connected to the front and rear lateral edges of the left and right walls (11,12) and a number of auxiliary walls (15) positioned between And is connected to the left and right walls (11,12) and extends over there, with the auxiliary wall (15) located at intervals determined between the front and rear walls (13,14), where The smooth pipe (17) has a parallel refrigerant channel (16) inside it and is made of sheet metal (21,22), with each auxiliary wall (15) comprising a reinforced wall that makes up the section. (25) extending inward from part (21) of the assembled plaque thereof. Which has the characteristics that The evaporator unit (55 A) consists of a number of refrigerant tube groups (58), each consisting of a number of refrigerant tubes (4) intermittently in the front-to-back direction and a group of tubes. Of refrigerant (58) aligned in a left to right direction. 2. Evaporator, as stated in claim 1, where the smooth tube (17) will consist of a piece The plate-like part (21), with the left wall part (23) and the right part, plate-like (22), with the right wall (28) and the front wall. And rear (13,14) .Each side of the smooth tube (17) consists of at least the right-hand (24) protruding wall that extends to the right from each front and rear edge of the left part ( 21) that are united in one place. And covered with the parts on the right And a wall that extends to the left (29) that extends to the left from each side, front and rear edge of the right part (22) that are united in there. And covered with the left part (21), with the reinforced wall (15) on each side of the smooth pipe (17) consisting of a supplementary wall that forms a section (25) extending from at least The left wall that makes up the portion (23) of the left piece (21) and the right wall that make up the portion (28) of the right piece (22), together in one place and having ends. Outside covered with Other walls that make up parts 3. Evaporator according to claim 2, where the auxiliary wall (15) will consist of a number of connecting holes (19) to make the parallel refrigerant channels (16) connected. And each other 4.
