DETAILED DESCRIPTION
[0031] In the following, certain example embodiments are simply described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. The drawings and description are therefore to be considered in an illustrative, rather than a restrictive, sense.
[0032] As Figures 1-13As shown, the embodiment provides a positioning structure of heat transfer plate 1, in particular, a positioning structure of heat transfer plate 1 for welded plate heat exchanger, which is based on heat transfer plate 1, and heat transfer plate 1 includes plate base surface 11 (refers to base plate before stamping) and first mounting protrusion 12, second mounting protrusion 13, first positioning protrusion 14, turbulence corrugated protrusion 15 and second positioning protrusion 16 formed by stamping on plate base surface 11; accordingly, the back side of first mounting protrusion 12 corresponds to form first mounting groove 121, the back side of second mounting protrusion 13 corresponds to form second mounting groove 131, the back side of first positioning protrusion 14 corresponds to form first positioning groove 141, the back side of turbulence corrugated protrusion 15 corresponds to form turbulence corrugated groove 151, and the back side of second positioning protrusion 16 corresponds to form second positioning groove 161. Before stamping, plate base surface 11 is a rectangular plate, which is generally hard aluminum plate or aluminum alloy plate, and can also be other plate materials that are easy to stamp and have good heat transfer performance. First mounting protrusion 12 and second mounting protrusion 13 are respectively arranged on the left and right edges of the front surface of plate base surface 11; in the embodiment, first mounting protrusion 12 is located on the left edge, and second mounting protrusion 13 is located on the right edge. First positioning protrusion 14 is arranged on the back surface of plate base surface 11, and a plurality of first positioning protrusions 14 are distributed at equal intervals between first mounting protrusion 12 and second mounting protrusion 13; turbulence corrugated protrusion 15 is arranged on the front surface of plate base surface 11, and is arranged between two adjacent first positioning protrusions 14 in the left-right direction, so that turbulence corrugated protrusion 15 can be engaged with first positioning protrusion 14 during assembly; the left and right sides of turbulence corrugated protrusion 15 are concave-convex surfaces, which can improve the turbulence effect, and when the side surface of first positioning protrusion 14 is attached to the concave-convex surface, it can be positioned and a gap is left to form first medium flow channel 2. Second positioning protrusion 16 is arranged on the front surface and / or back surface of first mounting protrusion 12 and second mounting protrusion 13; in the embodiment, second positioning protrusion 16 is arranged on the back surface of the front part of first mounting protrusion 12 and second mounting protrusion 13, and second positioning protrusion 16 is arranged on the front surface of the rear part of first mounting protrusion 12 and second mounting protrusion 13.
[0033] It should be noted that "front surface" and "back surface" are two surfaces of plate base surface 11, which are intended to distinguish which side of plate base surface 11 first mounting protrusion 12, second mounting protrusion 13, first positioning protrusion 14, turbulence corrugated protrusion 15 and second positioning protrusion 16 are located on; the left-right direction and the width direction are the same, and the front-rear direction and the length direction are the same.
[0034] In the present embodiment, in the left-right direction, the number of the first positioning protrusions 14 is one more than the number of the spoiler corrugated protrusions 15, the width of the first mounting protrusion 12 is greater than the width of the second mounting protrusion 13 and the first positioning protrusion 14, so that the rightmost first positioning protrusion 14 can extend into the first mounting groove 121; it should be noted that after the first positioning protrusion 14 extends into the first mounting groove 121, the two are not in contact, so that the first medium flow passage 2 can flow smoothly.
[0035] In the present embodiment, the first mounting protrusion 12 and the second mounting protrusion 13 extend along the length direction of the sheet base surface 11 to a position close to the front and rear ends of the sheet base surface 11.
[0036] In the present embodiment, in the front-rear direction, the first positioning protrusions 14 and the spoiler corrugated protrusions 15 are both provided with multiple and equal numbers, and the spacing of the first positioning protrusions 14 and the spoiler corrugated protrusions 15 adjacent in the front-rear direction is equal; in this way, the spoiler effect of the second medium flow passage 3 is enhanced, and at the same time, it is one of the bases for constructing the first medium flow passage 2 in the left-right direction.
[0037] In the present embodiment, the positions of the second positioning protrusions 16 on the first mounting protrusion 12 and the second mounting protrusion 13 are left-right symmetrical, so that they can be clamped in different postures; the height of the second positioning protrusion 16 is less than the height of the first mounting protrusion 12 and the second mounting protrusion 13.
[0038] In the present embodiment, the spoiler corrugated protrusion 15 and the first positioning groove 141 are adapted in length and width, so that they can be clamped and positioned; the heights of the first mounting protrusion 12, the second mounting protrusion 13, and the spoiler corrugated protrusion 15 are equal, and the heights of the first mounting protrusion 12, the second mounting protrusion 13, and the spoiler corrugated protrusion 15 are greater than the height of the first positioning protrusion 14, so that a gap is left at the bottom of the first positioning protrusion 14 and the spoiler corrugated groove, and the first medium flow passage 2 is constructed.
[0039] In assembly, the plurality of heat transfer plates 1 are stacked, specifically, a heat transfer plate 1 (referred to as a first plate) and a heat transfer plate 1 (referred to as a second plate) which is flipped 180° in the left-right direction are positioned by the first positioning protrusion 14 being clamped into the spoiler corrugated groove 151, the second plate and a heat transfer plate 1 (referred to as a third plate) which is rotated 180° counterclockwise (clockwise) are positioned by the second positioning protrusion 16 being clamped into the second positioning groove 161, the third plate and a heat transfer plate 1 (referred to as a fourth plate) which is flipped 180° in the front-back direction are positioned by the first positioning protrusion 14 being clamped into the spoiler corrugated groove 151, the fourth plate and the next first plate are positioned by the second positioning protrusion 16 being clamped into the second positioning groove 161, and so on. In this way, the adjacent heat transfer plates 1 are clamped to each other and are not easily displaced, ensuring assembly accuracy, and the first positioning protrusions 14, the spoiler corrugated protrusions 15, and so on are in contact with each other, thereby enhancing the anti-vibration and pressure-bearing capacity of the heat exchanger. The first to fourth plates refer to heat transfer plates 1 in different positions, and the structure of the heat transfer plates 1 is not changed.
[0040] After assembly, a first medium flow channel 2 extending in the left-right direction is formed between the first plate and the second plate, a second medium flow channel 3 extending in the front-back direction is formed between the second plate and the third plate, a first medium flow channel 2 extending in the left-right direction is formed between the third plate and the fourth plate, a second medium flow channel 3 extending in the front-back direction is formed between the fourth plate and the fifth plate, and so on. In this way, a plurality of first medium flow channels 2 and second medium flow channels 3 which are crisscrossed but not connected within the welded plate heat exchanger are formed. Generally, the plurality of first medium flow channels 2 are connected outside the heat exchanger by a flow divider and a flow combiner, and the plurality of second medium flow channels 3 are connected outside the heat exchanger by a flow divider and a flow combiner. The first medium flow channel 2 enters from the left end (or the right end), the first positioning protrusion 14 at the left end of the second plate does not contact the first mounting groove 121 (the groove corresponding to the first mounting protrusion 12) of the first plate, flows rightward and downward or rightward and upward from the gap between the first positioning protrusion 14 and the spoiler corrugated groove 151 (the gap is formed by the concave-convex surfaces on the left and right sides of the spoiler corrugated protrusion 15), and can flow forward, backward, and rightward in the gap between the top of the first positioning protrusion 14 and the bottom of the spoiler corrugated groove 151, thereby allowing the medium to flow between the two plates, and finally flowing out from the right end (or the left end), thus forming the second medium flow channel 3.
