DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be interpreted as limitations on the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] Figure 1 A schematic diagram of the explosion structure of the first sintering mold provided by the embodiment of the utility model; Figure 2 A schematic diagram of the three-dimensional structure of the first sintering mold provided by the embodiment of the utility model; Figure 1 and Figure 2 As shown: The embodiment of the present application discloses a sintering mold for a heat exchanger plate, comprising: a core body 10; a first hollow column 20 coaxially sleeved on the outer wall of the core body 10; a second hollow column 30 coaxially sleeved on the outer wall of the first hollow column 20; wherein the first hollow column 20 is clearance-matched with both the core body 10 and the second hollow column 30, and the side wall of the first hollow column 20 is provided with a plurality of first through holes 23 whose shape is defined by the heat exchange plate and radially penetrate the first hollow column 20 along the first hollow column 20; any first through hole 23 cooperates with the outer wall of the core body 10 and the inner wall of the second hollow column 30 to form a first groove for accommodating a sintering material, so as to allow the sintering mold to form the heat exchange plate from the sintering material after sintering.

[0044] By opening a plurality of first through holes 23 on the side wall of the first hollow column 20, any of the first through holes 23 cooperates with the outer wall of the core body 10 and the inner wall of the second hollow column 30 to form a first groove for accommodating the sintered material. The plurality of first through holes 23 form a plurality of first grooves. When the first grooves are filled with the sintered material, the sintering mold is subjected to high-temperature sintering to form a plurality of heat exchange plates, thereby improving production efficiency. In addition, the core body 10 and the second hollow column 30 of this embodiment can not only limit and fix the axial direction of the first hollow column 20, but also provide heat conduction, so that the temperature during sintering can be simultaneously transmitted to the first hollow column 20 in the inner and outer directions through the second hollow column 30 and the core body 10, ensuring that the temperature of the first hollow column 20 is uniform and rises rapidly, thereby ensuring that the sintered material in the first groove is heated uniformly and heats up rapidly, so that the performance of the heat exchange plate formed after sintering is better.

[0045] In this embodiment, the shape of the first groove can be set according to the shape of the heat exchanger plate, and the depth of the first groove can also be determined according to the thickness of the heat exchanger plate. For heat exchangers of different shapes and thicknesses, a first groove of corresponding depth and shape can be used, and the first through hole 23 on the first hollow column 20 can be adjusted accordingly. At the same time, it is ensured that the second hollow column 30 and the core body 10 are sleeved with the first hollow column 20 along the axial gap.

[0046] In this embodiment, the shapes of the first hollow column 20, the second hollow column 30, and the core body 10 can be circular, square, rectangular, diamond, etc., ensuring that the three can be sleeved along the axial direction and the first groove formed by the three after matching matches the shape of the heat exchange plate; for example, Figure 1 As shown, the core body 10 is a cylinder, and the first hollow column 20 and the second hollow column 30 are both annular columns; in order to facilitate the installation and disassembly of the three, in some implementations of this embodiment, the outer wall of the core body 10, the inner wall and outer wall of the first hollow column 20, and the inner wall of the second hollow column 30 all have a taper.

[0047] In this embodiment, the arrangement of the plurality of first through holes 23 is not specifically limited, and three structures of the first hollow column 20 under different arrangements of the plurality of first through holes 23 are given as follows.

[0048] Example 1: The first hollow column 20 includes a hollow seat 21 with a notch and a plurality of axially stacked and spaced pressing blocks 22 disposed at the notch; the notch penetrates the inner and outer walls of the hollow seat 21 so that a plurality of the first through holes 23 are formed at the plurality of the spaced locations. Specifically, Figure 1 As shown, when two pressing blocks 22 are arranged at the notch, when filling the sintered material, the hollow seat 21 is first coaxially sleeved on the outer wall of the core body 10, and then the second hollow column 30 is coaxially sleeved on the outer wall of the hollow seat 21; then the notch of the hollow seat 21 is filled with a preset amount of sintered material for the first time, and when the sintered material is filled, one of the pressing blocks 22 is placed on top of the sintered material, and then the upper surface of the pressing block 22 is filled with a preset amount of sintered material for the second time, and when the sintered material is filled, the other pressing block 22 is placed on top of the sintered material, so that the sintering mold can prepare two heat exchanger plates at the same time. In this embodiment, by arranging the pressing block 22 above the sintered material, the sintered material is not only pressed more compactly, but also distributed more evenly, so that the performance of the heat exchanger plate finally obtained is more stable.

[0049] Example 2: The first hollow column 20 includes a hollow seat 21 with a plurality of notches and a pressing block 22 disposed at each notch and spaced apart from the notch along the axial direction; the plurality of notches are arranged along the radial direction of the hollow seat 21 and any of the notches penetrates the inner and outer walls of the hollow seat 21 so that the first through hole 23 is formed at the spaced locations. Specifically, Figure 3 A schematic diagram of the explosion structure of the second sintering mold provided by the embodiment of the utility model; Figure 4 A schematic diagram of the three-dimensional structure of a second sintering mold provided by an embodiment of the utility model; Figure 3 and Figure 4 As shown: when there are two notches, when filling the sintered material, the hollow seat 21 is first coaxially sleeved on the outer wall of the core body 10, and then the second hollow column 30 is coaxially sleeved on the outer wall of the hollow seat 21; then the two notches of the hollow seat 21 are filled with a preset amount of sintered material, and when the sintered material is filled, the two pressing blocks 22 are respectively placed on the sintered materials at the two notches, so that the sintering mold can prepare two heat exchanger plates at the same time. In this embodiment, by setting the pressing block 22 above the sintered material, the sintered material is not only pressed more compactly, but also distributed more evenly, so that the performance of the heat exchanger plate finally obtained is more stable.

[0050] In this example, the hollow seat 21 can be an integrally formed structure or a structure composed of multiple parts; in some implementations of this embodiment, the hollow seat 21 includes a plurality of arc blocks 211 arranged at intervals around its central axis and a separator block 212 disposed between adjacent arc blocks 211; the separator block 212 is gap-matched with the arc block 211 and the height of the separator block 212 is higher than the arc block 211 to form a plurality of the gaps. For example, Fig. 9 A schematic diagram of an exploded structure of a first hollow column 20 provided in an embodiment of the utility model is shown as follows: Fig. 9 As shown: the hollow seat 21 includes two arc blocks 211 and two separator blocks 212, forming two gaps. When filling the sintering material, the arc blocks 211 and the separator blocks 212 are first coaxially attached to the outer wall of the core body 10, and then the second hollow column 30 is coaxially sleeved on the outer wall of the arc blocks 211 and the separator blocks 212 to form two gaps; then a preset amount of sintering material is filled in the two gaps of the hollow seat 21. When the sintering material is filled, the two pressing blocks 22 are respectively placed above the sintering material at the two gaps, so that the sintering mold can prepare two heat exchanger plates at the same time.

[0051] Example 3: The first hollow column 20 includes a hollow seat 21 with a plurality of notches and a plurality of pressure blocks 22 arranged at each notch and stacked in the axial direction and arranged at intervals; the plurality of notches are arranged in the radial direction of the hollow seat 21; each of the notches penetrates the inner and outer walls of the hollow seat 21 so that a plurality of the first through holes 23 are formed at the plurality of intervals. Specifically, Figure 5 A schematic diagram of the explosion structure of a third sintering mold provided by an embodiment of the utility model; Figure 6 A schematic diagram of the three-dimensional structure of a third sintering mold provided by an embodiment of the utility model; Figure 5 and Figure 6 As shown, the first hollow column 20 includes a hollow seat 21 with two notches, and each notch is provided with two pressing blocks 22 stacked axially and arranged at intervals. The steps of filling the sintering material are analogous to those of Examples 1 and 2 above. The sintering mold of this example can prepare 4 heat exchange plates at the same time.

The first fixing member 40 and the second fixing member 50 are used to fix the sleeved core body 10, the first hollow column 20, and the second hollow column 30 to prevent shaking from affecting the heat conduction effect during sintering.

[0053] Continue as Figure 7 As shown, in some implementations of the present embodiment, the first fixing member 40 and the second fixing member 50 are provided with a plurality of second through holes corresponding to each other along the periphery, and the second through holes are used for fixing the first fixing member 40 and the second fixing member 50 with bolts 60. Specifically, the sizes of the first fixing member 40 and the second fixing member 50 are respectively larger than the sizes of the second hollow column 30, and a plurality of second through holes corresponding to each other are provided on the outer periphery of the first fixing member 40 and the second fixing member 50, and the first fixing member 40 and the second fixing member 50 are fastened and connected by fastening the bolts 60 through the second through holes, so as to ensure the fixing and pressing effect of the first hollow column 20, the second hollow column 30 and the core body 10 after loading.

[0054] Fig.10 A schematic diagram of the structure of a bolt 60 provided in an embodiment of the utility model; Fig.10 As shown: In some implementations of this embodiment, a first spring washer 61 and a second spring washer 62 are sleeved on the screw rod of the bolt 60, the first spring washer 61 is attached to the upper end surface of the first fixing member 40, and the second spring washer 62 is attached to the lower end surface of the second fixing member 50. By providing the first spring washer 61 and the second spring washer 62, the fixing and pressing effect of the first hollow column 20, the second hollow column 30 and the core body 10 after loading is further ensured; in addition, the resilience of the first spring washer 61 and the second spring washer 62 can also be relied on to provide the mold pressure loss caused by the sintering shrinkage of the sintering material.

[0056] By providing the first pressure column 70 and the second pressure column, the radial positions of the first fixing member 40 and the second fixing member 50 can be fixed, so as to avoid uneven force on the first fixing member 40 and the second fixing member 50 due to the tightening of the bolt 60, thereby affecting the fixing effect. In a specific implementation, the first pressure column 70 and the second pressure column can be in various shapes such as a cylinder, a square column, and a circular ring column; they can be solid metal columns or hollow metal columns.
