Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange parts, and specifically relates to a plate heat exchanger. Background Art

[0002] There are many types of heat exchangers located in the mold temperature controller, such as the common plate heat exchanger, which mainly uses screws to fix multiple layers of heat exchange plates together, and the hot and cold fluids are discharged through the corner holes to complete the heat transfer.

[0003] It is worth noting that the distance between the heat sink fins largely determines its heat dissipation effect. When dealing with variable amounts of hot and cold fluid conversion, we can appropriately adjust the distance between the heat sink fins according to actual needs, but existing heat sinks are clamped by screws. If the distance needs to be adjusted, the screws must be loosened first. In this way, all the heat sink fins will lose control and cannot be adjusted evenly. Utility Model Content

[0020] Example 1

[0021] like Figures 1 to 4The plate heat exchanger with adjustable heat dissipation shown in the figure comprises a shell 1, a support plate 2 is arranged on the right side of the shell 1, a first guide rail 3 is symmetrically arranged on the left side of the support plate 2, a first end plate 4 and a second end plate 5 are connected between the first guide rails 3, a plurality of heat exchange cores 6 are slidably arranged on the first guide rail 3, and is characterized in that a second guide rail 7 is symmetrically arranged on the rear side of the shell 1, a guide block 8 is arranged on the front side of the second guide rail 7, a distance exchange plate 9 is connected between the guide blocks 8, a plurality of inclined holes 10 are opened on the distance exchange plate 9, and a slider 11 is arranged on the rear side of the lower part of the heat exchange core 6; the number of the inclined holes 10 is the same as that of the heat exchange core 6; the inner wall of the shell 1 A receiving plate 12 is symmetrically arranged at the right side of the pitch-changing plate 9, and a screw 13 is rotatably arranged between the receiving plates 12, and the screw 13 passes through the top of the shell 1 and is connected to a handle 14; a connecting block 15 is arranged on the right side of the pitch-changing plate 9, and the connecting block 15 is rotatably connected to the screw 13; the first end plate 4 is fixedly connected to the left side of the first guide rail 3, and the second end plate 5 is slidably connected between the first guide rails 3; a support frame 16 is connected to the top of the second end plate 5, and a roller 17 is rotatably arranged on the support frame 16; the roller 17 is in contact with the top of the first guide rail 3; the heat exchange core 6 is located between the first end plate 4 and the second end plate 5.

[0022] The utility model provides a distance exchange plate 9 with the same number of sliding holes as the heat exchange core 6. When the heat exchange core 6 in its initial combined state is placed in the distance exchange plate 9, the heat exchange core 6 is slidably arranged in the sliding holes. When the distance exchange plate 9 moves downward, the heat exchange core 6 will be evenly dispersed outward under the action of the distance exchange plate 9, thereby realizing the equidistant adjustment of the heat exchange core 6. At the same time, a screw rod 13 is provided on the right side of the distance exchange plate 9 for linkage, so that the operator can indirectly realize the up and down adjustment of the heat exchange core 6 outside the machine without performing unnecessary and complicated disassembly steps, thereby reducing labor costs.

[0023] Example 2

[0024] like Figures 1 to 4 A plate heat exchanger with adjustable heat dissipation is shown, including a shell 1, which specifically refers to the shell 1 of the mold temperature controller, which protects the plate heat exchanger and other electronic components inside it. A support plate 2 is provided on the right side of the shell 1, and a first guide rail 3 is symmetrically provided on the left side of the support plate 2. A first end plate 4 is connected between the left sides of the first guide rail 3. The first end plate 4 is fixedly arranged on the first guide rail 3, and together with the support plate 2, it forms a movable periphery of the heat exchange plate; a plurality of heat exchange cores 6 are slidably connected between the first guide rails 3. The heat exchange core 6 is composed of 2 layers of corrugated thin plates and a layer of ventilation plate sandwiched therein. The thickness and mass are greater than those of common heat exchange plates. Therefore, it will not easily break or be damaged during movement, and it is more convenient to adjust the heat exchange core 6.

[0025] A second end plate 5 is also slidably connected between the first guide rails 3. The second end plate 5 is located on the right side of the heat exchange core 6 and is connected to the rightmost heat exchange core 6. They are mutually restrained. When the sheet spacing of the heat exchange core 6 is adjusted, the second end plate 5 can follow the movement on the first guide rail 3 to maintain the limit on the right side of the heat exchange core 6. A support frame 16 is also connected to the second end plate 5. A roller 17 is rotatably provided on the support frame 16. The bottom of the roller 17 is in close contact with the top of the first guide rail 3. The existence of the roller 17 greatly reduces the friction resistance during the movement, so that the second end plate 5 can move more smoothly and easily with the assistance of the roller 17.

[0026] Example 3

[0027] like Figures 1 to 4 The plate heat exchanger with adjustable heat dissipation shown in the figure can drive the heat exchange core 6 to move on the first guide rail 3 to adjust the plate spacing; and in order to further achieve the equidistant adjustment between the heat exchange cores 6, a distance exchange plate 9 is specially provided, and the distance exchange plate 9 can achieve the action of moving up and down, and a plurality of sliding holes are opened on the distance exchange plate 9, the number of sliding holes is the same as the number of heat exchange cores 6, and the inclination angles are equal, that is, the distances between the sliding holes located at the same horizontal position are equal; it can be imagined that when the initial combined state of the heat exchange core 6 is placed in the distance exchange plate 9, the heat exchange core 6 is respectively slidably arranged in the sliding holes, and when the distance exchange plate 9 moves downward, the heat exchange core 6 will be dispersed outward equidistantly under the action of the distance exchange plate 9, so as to achieve the equidistant adjustment of the heat exchange core 6.

[0028] Therefore, a second guide rail 7 is symmetrically provided on the rear side of the inner wall of the shell 1, which is used to connect the heat exchange core 6 and drive it to move up and down. Guide blocks 8 are slidably provided on the second guide rail 7, and distance exchange plates 9 are connected between the guide blocks 8. The distance exchange plates 9 are provided with multiple inclined sliding holes; sliders 11 are provided on the rear side of the heat exchange core 6, and the sliders 11 are slidably connected with the sliding holes. When the distance exchange plate 9 moves downward, the sliders 11 can drive the heat exchange core 6 to spread outward between the first guide rails 3, otherwise it can gather inward, and the second end plate 5 will move with the heat exchange core 6 on the far right to realize the limitation of all heat exchange cores 6.

[0029] Example 4

[0030] like Figures 1 to 4The plate heat exchanger with adjustable heat dissipation shown in the figure drives the distance exchange plate 9 to move up and down, drives the heat exchange core 6 to spread outward between the first guide rails 3, and vice versa, gathers inward, completes the one-time distance adjustment of the heat exchange core 6, and ensures that the distance between the heat exchange cores 6 is equal. In order to more easily adjust the heat exchange core 6, a receiving plate 12 is provided at the right side of the distance exchange plate 9 in the housing 1. The receiving plates 12 are provided with two, which are symmetrical up and down. The receiving plates 12 are rotatably connected with a screw rod 13, and the screw rod 13 passes through the top of the housing 1 and is connected with a handle 14, that is, the operator can indirectly adjust the heat exchange core 6 up and down by rotating the handle 14 on the outside of the cold and hot exchanger, without unnecessary and complicated disassembly steps; and the right side of the distance exchange plate 9 is connected to the screw rod 13 by a fixed connection block 15, and the rotation of the screw rod 13 can drive the distance exchange plate 9 to move up and down under the action of the connection block 15, thereby realizing the automatic distance change of the heat exchange core 6.

[0031] It should be noted that in order to further reduce labor costs and achieve precise adjustment, the operator can choose to replace the handle 14 with a motor, and realize the rotation of the screw 13 by controlling the operation of the motor outside the machine. At the same time, the self-locking function of the motor shaft can be used to achieve stable maintenance of the adjusted sheet spacing.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0033] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
