The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0016] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:
[0017] A radiator for a refrigeration system includes a flat tube 1, the flat tube 1 having a contact surface for contacting a metal material, the contact surface being arranged along the length of the flat tube 1, and contact surfaces being arranged opposite to each other on both sides of the flat tube; by flattening, the contact area between the metal material and the flat tube 1 is increased, the contact area between the condenser tube and the metal material of the casing is increased, thereby improving the heat dissipation effect, and the increased contact area between the condenser tube and the metal material of the casing further enhances the heat dissipation effect and reduces energy consumption.
[0018] The flat tube 1 is a split structure, comprising: a flat tube body 11 and inner fins 12.
[0019] The flat tube body 11 has a tubular structure, and the inner fins 12 are arranged inside the flat tube body 11 and along the length direction of the flat tube body 11.
[0020] The inner fin 12 is an aluminum corrugated fin formed by stamping or rolling aluminum foil, and the corrugation direction is the same as the flow channel direction of the flat tube.
[0021] Furthermore, the cross-section of the flat tube body 11 is a combination of a rectangle and two arcs, or in other words, the flat tube body 11 comprises a tubular structure composed of two planar plates and two arc-shaped plates.
[0022] The width of the inner fin 12 is greater than the length of the straight side of the cross-section of the flat tube body 11, and less than the length of the farthest point of the inner arc at both ends of the cross-section of the flat tube body 11 (i.e., the width of the inner fin 12 is less than the width of the inner channel), and the height of the inner fin 12 is less than the height of the inner channel of the flat tube body 11, so as to achieve the positioning purpose of the inner fin 12 in the middle of the flat tube, ensuring that the inner fin 12 divides the interior of the flat tube into two approximately uniform channels. The edge of the inner fin 12 contacts the inner wall of the flat tube body 11 (point contact), so that the inner fin 12 is used in accordance with the size of the flat tube.
[0023] Furthermore, the inner fin 12 is a long strip-shaped thin plate structure, and the inner fin 12 includes: a protrusion and a recess.
[0024] Furthermore, there are multiple protrusions and recesses, and the protrusions and recesses are distributed alternately. Specifically, the protrusions and recesses are distributed alternately along the length direction of the inner fin 12, and the transition is smooth.
[0025] Furthermore, the protrusions and recesses have the same shape.
[0026] Furthermore, the shapes of the protrusions and recesses can be sinusoidal, semi-circular, rectangular, triangular, or U-shaped, etc.
[0027] Furthermore, in this embodiment, the length direction of the flat tube body 11, the length direction of the inner fins 12, and the fluid flow direction are consistent (the same).
[0028] In other words, the inner fin 12 has a corrugated structure, and the direction of the corrugations is the same as the flow direction of the fluid inside the flat tube 1. The arrow indicates the flow direction of the fluid.
[0029] The inner fins 12 divide the internal channel of the flat tube body 11 into two gradually narrowing-widening sub-channels. The high-temperature liquid flows through the two sub-channels of the flat tube 1, and the high-temperature liquid comes into contact with the surface of the flat tube body 11 and the inner fins 12 to exchange heat, thus completing the heat dissipation function of the high-temperature liquid.
[0030] In other words, the inner fin 12 divides the flat tube flow channel into two flow channels with a periodically narrowing-widening cross-section. For each individual flow channel, the inner fin and the flat tube wall form a narrowing-widening channel with a periodically changing cross-section in the flow channel direction.
[0031] In this embodiment, preferably, the inner fin 12 has a sinusoidal waveform.
[0032] The corrugated inner fins 12 include, but are not limited to, streamlined shapes, as well as other shapes such as serrated, triangular, rectangular, and U-shaped. The characteristic is that the fins and the flat tube wall form a periodic converging-expanding channel along the flow direction.
[0033] Alternatively, another type of spliced flat tube is provided, with the flat tube body 11 designed as a rectangular tube having four planar sides; and the flat tube body 11 is a split structure, comprising two half tubes, namely the first half tube 111 and the second half tube 112, the flat tube body 11 being spliced together from the first half tube 111 and the second half tube 112, and the flat tube 1 being a spliced flat tube.
[0034] Furthermore, the edges of the first and second half-tubes can fit against the upper or lower surface of the inner fin 12; that is, both ends of the inner fin 12 are engaged between the two opposite end faces of the first half-tube 111 and the second half-tube 112.
[0035] Specifically, the lower end face of the first half-tube 111 is attached to the upper surface of the inner fin 12; the upper end face of the second half-tube 112 is attached to the lower surface of the inner fin 12.
[0036] Furthermore, the width of the inner fin 12 is the same as the width of the flat tube body 11.
[0037] Specifically, the radiator flat tube of the present invention is formed by welding the inner fins 12, the first half-tube 111, and the second half-tube 112.
[0038] Furthermore, the flat tube 1 is a rectangular tube, and the four corners of the rectangular flat tube body 11 are set as chamfers or rounded corners.
[0039] Due to the heat transfer and flow resistance characteristics of the converging-expanding channel, when the high-temperature liquid flows through the converging-expanding channel in the flat tube 1, the fluid is in a state of continuous compression and expansion, which improves the heat exchange efficiency between the high-temperature fluid and the flat tube. Furthermore, because the heat exchange efficiency of the flat tube 1 is greatly improved, the anti-fouling ability is enhanced, the flow path of the fluid is extended, and the heat exchange area between the fluid and the flat tube 1 is increased, the overall heat exchange capacity between the fluid and the flat tube 1 is improved.
[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
