Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, specifically relating to a heat dissipation structure for a light-blocking plate, a printing component, and printing equipment. Background Technology

[0002] Printing equipment includes printing components, on which light-blocking plates are installed. However, after a certain period of operation, due to the limited installation space and small size of the light-blocking plates, the heat dissipation area is insufficient. When exposed to light sources for a long time, the heat accumulation rate exceeds the heat dissipation rate, resulting in a local temperature rise. This temperature rise will affect the stability of digital printing. To solve the technical problem of poor heat dissipation of the light-blocking plates, it is necessary to develop a heat dissipation structure for the light-blocking plates, printing components, and printing equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation structure, printing component and printing equipment for a light-blocking plate to solve the above-mentioned technical problems. The heat dissipation module is set so that the light-blocking plate body can dissipate heat synchronously during operation. The heat dissipation module is set on one side of the light-blocking plate body and transfers heat in a close-fitting manner, thereby increasing the heat dissipation area of ​​the light-blocking plate in the heat dissipation process.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A heat dissipation structure for a light-blocking plate includes a light-blocking plate body. A heat dissipation module is attached to one side of the light-blocking plate body and projected perpendicularly to the extending direction of the light-blocking plate body. The projection surface of the heat dissipation module falls within the projection range of the light-blocking plate body. The heat dissipation module allows the light-blocking plate body to dissipate heat simultaneously during operation. The heat dissipation module is located on one side of the light-blocking plate body and transfers heat in a bonded manner, thereby increasing the heat dissipation area of ​​the light-blocking plate during heat dissipation.

[0006] Preferably, the light-blocking plate body is provided with a light-blocking surface and a bonding surface in the direction perpendicular to the extension direction;

[0007] The heat dissipation module includes a bonding block with one end attached to a bonding surface. The bonding block extends along the extension direction of the bonding surface; an extension spacing is provided along the extension direction from the light-blocking surface to the bonding surface. The additional bonding block is bonded to the side away from the light-blocking surface, allowing heat from the light-blocking plate to be transferred through the bonding block, thereby increasing the heat dissipation area. Furthermore, the extension spacing further increases the heat dissipation area.

[0008] Preferably, the bonding block has a through-hole for heat dissipation. The axial direction of the heat dissipation hole is perpendicular to the extension direction of the bonding block; along the extension direction from the light-blocking surface to the bonding surface, the projection of the bonding block falls within the projection range of the bonding surface. By providing a bonding block and a through-hole for heat dissipation, the heat dissipation area of ​​the light-blocking plate body is increased compared to a plate without a heat dissipation structure.

[0009] Preferably, one heat dissipation hole or multiple heat dissipation holes are provided along the extension direction of the bonding block. In this technical solution, providing multiple heat dissipation holes is beneficial to improving the heat dissipation effect.

[0010] Preferably, the cross-sectional shape of the heat dissipation through-hole is one of the following: circular, rounded square, elliptical, or polygonal. Specifically, in this technical solution, the cross-sectional shape of the heat dissipation through-hole is a rounded square.

[0011] Preferably, the bonding block is equipped with one or more cooling fans, which are connected to the heat dissipation holes. The cooling fans accelerate airflow, allowing the flowing air to contact the bonding block and the inner walls of the heat dissipation holes, thereby carrying away heat and increasing the rate of heat dissipation. Simultaneously, the axial direction of the heat dissipation holes is perpendicular to the extension direction of the bonding block, allowing multiple heat dissipation holes to be arranged along the extension direction of the bonding surface. Furthermore, during airflow, the heat dissipation holes contain multiple airflows perpendicular to the extension direction of the bonding block, improving the heat dissipation effect.

[0012] Preferably, the cooling fan includes a first cooling fan, a second cooling fan, and a third cooling fan arranged sequentially along the extension direction of the mating block;

[0013] A gap is provided between the first cooling fan and the second cooling fan;

[0014] A gap is provided between the second and third cooling fans. The first, second, and third cooling fans are arranged on the same straight line. The spacing between the first, second, and third cooling fans ensures airflow in multiple sections along the extension direction of the contact block, thereby improving the heat dissipation effect.

[0015] Preferably, multiple heat dissipation holes are provided, with the first cooling fan coaxially connected to one of the heat dissipation holes; the second cooling fan coaxially connected to one of the heat dissipation holes; and the third cooling fan coaxially connected to one of the heat dissipation holes. The cooling fans are coaxially arranged at their connections to the heat dissipation holes; the first, second, and third cooling fans coaxially connected to one of the heat dissipation holes allow airflow to pass through them. This connection scheme also requires less space.

[0017] This technical solution also provides a printing device, which includes the aforementioned printing components.

[0026] Reference Figures 1 to 2 A heat dissipation structure for a light-blocking plate includes a light-blocking plate body 1. A heat dissipation module 2 is attached to one side of the light-blocking plate body 1 and projected perpendicularly to the extending direction of the light-blocking plate body 1. The projection surface of the heat dissipation module 2 falls within the projection range of the light-blocking plate body 1. The heat dissipation module 2 allows the light-blocking plate body 1 to dissipate heat synchronously during operation. The heat dissipation module 2 is located on one side of the light-blocking plate body and transfers heat in a bonded manner, thereby increasing the heat dissipation area of ​​the light-blocking plate during heat dissipation.

[0028] The heat dissipation module 2 includes a bonding block 21 with one end bonded to the bonding surface 12. The bonding block 21 extends along the extension direction of the bonding surface 12; and along the extension direction from the light-blocking surface 11 to the bonding surface 12, the bonding block 21 has an extension spacing. The added bonding block 21 is bonded to the side away from the light-blocking surface 11, so that the heat of the light-blocking plate body 1 is transferred through the bonding block 21, thereby increasing the heat dissipation area during the heat dissipation process. Furthermore, the extension spacing further increases the heat dissipation area.

[0029] The bonding block 21 is provided with a heat dissipation through hole 22. The axial direction of the heat dissipation through hole 22 is perpendicular to the extension direction of the bonding block 21; along the extension direction from the light-blocking surface 11 to the bonding surface 12, the projection of the bonding block 21 falls within the projection range of the bonding surface 12. Based on the bonding block 21, the heat dissipation through hole 22 is provided on the bonding block 21, thereby increasing the heat dissipation area of ​​the light-blocking plate body 21 compared to the area without a heat dissipation structure.

[0032] The bonding block 21 is equipped with one or more cooling fans 23, which are connected to the heat dissipation holes 22. The cooling fans 23 accelerate airflow, and the flowing air contacts the inner walls of the bonding block 21 and the heat dissipation holes 22, thereby carrying away heat and increasing the rate of heat dissipation. Simultaneously, the axial direction of the heat dissipation holes 22 is perpendicular to the extension direction of the bonding block, allowing multiple heat dissipation holes 22 to be arranged along the extension direction of the bonding surface 12.

The first cooling fan 232, the second cooling fan 232, and the third cooling fan 233 with a certain gap are arranged so that air can flow in multiple sections of the attached block in the extension direction, thereby improving the heat dissipation effect.

[0036] Multiple heat dissipation holes 22 are provided. The first cooling fan 231 is coaxially connected to one of the heat dissipation holes 22; the second cooling fan 232 is coaxially connected to one of the heat dissipation holes 22; and the third cooling fan 233 is coaxially connected to one of the heat dissipation holes 22.

Specifically, the support members 4 are disposed below both sides of the light-blocking plate body 1, wherein the upper end surface of the bonding block 21 is flush with the upper end surface of the support member 4.
