Abstract

The heat exchanger has a flat tube (1) positioned parallel. And stay away from each other Is the specified distance Advance in the direction of thickness, the heat exchanger also has A pair of (5,6) headers where the ends of the hoses are connected. Match with that In fluid contact welding, each pipe (1) has a central bent part (4), a part that is twisted at a helical angle. As predetermined In relation to each straight section, fins (11) are interpolated between adjacent straight sections (2) and additional fins (12) between the other straight segments (3). Improved productivity and heat exchanger efficiency, even if the tube is bent in the direction of its width.

Claims (3)

1. A heat exchanger consists of a number of (1) flat tubes arranged at even intervals and parallel to and at a distance from each other. Predetermined in the direction of the thickness of a pair of hollow header tubes (5,6) arranged at the ends. One end and another end One side of the pipe (1), which is connected to That, in the manner of connecting the fluid contact with that, each pipe (1) has a central bent section (4) and a straight section (2,3) separated from each other by the bent section. A (4) and fins (11,12), each of which is arranged Between the vertical sections Adjacent (2,3) has a unique characteristic that The bent part (4) is a part of each tube (1) that is bent in the direction of the pipe thickness (1) and is twisted to a helical angle at Predetermined relative to each of the straight sections (2,3) so that the inner part Each of the flat ducts (1) is divided into a parallel flow path, the northwind portion where one of them in a straight section (2) continues with the south unit path. Wind in another straight line (3) or vice versa Compared with the air flow when operating through the gap between the vertical straight sections. Adjacent (2,3) 2. The heat exchanger, as requested in Clause 1, also includes additional fins (11,12) arranged outside the outermost tube (1) and pieces. Reinforcement (13,14), each of which is made up of the middle part (15) and the end (16) that are connected from there where the middle part (15) of each reinforcement (13,14) There are slots (15a) formed through them, each of which Is on the area between the straight part (2,3) and the Twisted bends (4) of each tube (1) and each end (16) of reinforcement (13,14) protruding and fixed. Firmly fixed to the outer surface of the fin added Fill the corresponding (11,12) 3.heat exchanger As requested in the Clause 1 or 2, it has a unique feature that The bent and bit (4) parts that are aligned to each other touch and overlap. To reinforce all such parts. 4. Heat exchanger As requested in Clause 3, there is a unique feature that The bent and twisted parts (4) are soldered together. 5. Heat exchanger. As requested to hold the right in the claim Any of the above rights has a unique characteristic that the headers (5,6) are aligned and the straight sections (2,3) of each pipe (1) are upright so that the machine exchange Heat is applied to Work as an evaporator 6. Heat exchanger As requested to hold the rights in any of the 1 to 5 rights It has a unique feature that Each of the (5,6) headers has an inner part that is not divided into chambers so that the heat exchanger medium flows to the One (5) header moves as a part that flows like a hamo. This goes through all the tubes (1) one time and goes to the other header (6) where the heat exchanger is formed. As evaporator One-time type 7. Heat exchanger As requested to hold the rights in any of the 1 to 4 rights It has a unique feature that the headers (5,6) are upright and the straight sections (2,3) of each pipe (1) are aligned to allow the exchanger to Heat is applied To work as a condenser. 8. Heat exchanger As requested to hold the right in the claim Any of the above rights has a unique characteristic that Each (5,6) header has a cross-sectional shape with a flat bottom section that continues to the dome. So that the bottom part accepts the pipe that is inserted there. 9. Heat exchanger. As requested to hold the rights in any of the claims 1 to 7 It has a unique feature that Each (5,6) header has a cross-sectional shape that Composed by Half round inside and outside And the radius of curvature of the surrounding half The inside receiving pipe is greater than the radius of curvature of Outer half surrounding 1 0. heat exchanger As requested to hold the rights in any of the claims 1 to 7 It has a unique feature that Each header (5,6) is a barrel made with Solder pads that are assembled With at least one side covering core part, using a solder layer and soldered edge solder together 1 1.Heat exchanger As in any of the rights in clause 2 to 10 It has a unique feature that Each central section (15) of the reinforcement (13,14) has a vent hole (15b) and / or a drain (15c). The hole (15b) is formed through the central section (15), and with The rail (15c) was formed there 1 2.Heat exchanger As requested to hold the right in the claim Any of the above rights is characterized by the fact that the header (6) is connected to the inlet pipe (7) of the heat exchanger has an internal tube (60) that is bolted in and coaxial. As with the header (6), the inner tube (60) is connected to the inlet pipe and where the inlet pipe (7) and the outlet pipe (8) are attached to the header (5,6). At the ends of it being placed side by side 1 3.Heat exchanger As claimed in claim 12, it is characterized by that the internal pipe (60) has a small hole (60a) corresponding to the pipe (1) so that the heat exchanger medium is distributed evenly over the pipe.
