Detailed Description
For the purpose of facilitating an understanding of the technical features, contents and advantages of the present invention, and the technical effects achieved thereby, the present invention will be described in detail by embodiments with reference to the accompanying drawings, wherein the drawings are used for illustrative purposes and for supporting the specification, and are not intended to be in actual scale and precise configuration after the implementation of the present invention, and therefore the scope of the present invention is not to be read and limited by the appended drawings in terms of scale and configuration.
Advantages, features and embodiments of the invention will be described in greater detail with reference to exemplary embodiments and the accompanying drawings so that the invention may be more readily understood, and may be embodied in different forms, and therefore should not be construed as limited to the embodiments set forth herein, but rather should be construed as providing embodiments that will fully convey the scope of the invention and that will be defined only by the appended claims to which the invention pertains, to a person of ordinary skill in the art having the benefit of the common general knowledge in the art.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a copier of the present invention, and fig. 2 is a schematic diagram of a heat dissipation and flow guiding structure of the present invention. As shown in fig. 1, the copier 100 includes a main body 10, a scanning module 20, an image forming module 30, a fixing module 40, and a heat dissipation structure 50. The device body 10 may have a plurality of ventilation holes 14, and particularly, an open structure ventilation hole feature disposed below the positioning module 40. in practice, the device body 10 may further include a plurality of raised foot pads 18 below the positioning module to increase ventilation space, so that external air can enter the device body 10 to form a heat dissipation airflow. The scanning module 20 is disposed above the device body 10 for a user to scan a document. The image forming module 30 is disposed inside the apparatus body 10, and the image forming module 30 forms an image on a sheet of paper by means of a photoreceptor drum and transfers the image onto the sheet of paper. The fixing module 40 fixes and cures the paint transferred to the sheet through a thermal fixing step to complete the job of copying data.
The heat dissipation and flow guiding structure 50 is disposed between the fixing module 40 and the image forming module 30 to dissipate the high temperature generated by the fixing module 40 during the thermal fixing step to avoid the accumulation of waste heat, the heat dissipation and flow guiding structure 50 includes a heat insulation plate 51 and a flow guiding plate 52, the heat insulation plate 51 and the flow guiding plate 52 are spaced a certain distance apart to form a first air flow channel 55 to avoid the high temperature affecting the image forming module 30. In practice, the baffle 52 may utilize the temperature difference effect of the air flow and form an insulating air curtain 555 at the first air flow channel 55 according to the arc-shaped structure of the baffle 52, and in practice, the surface of the baffle 52 may further include a plurality of guide lines to increase the stability of the insulating air curtain 555.
Further, the heat-insulating air curtain 555 can effectively separate the ambient temperature on the two sides of the baffle plate 52, so as to prevent the high-temperature air flow 565 of the fixing module 40 from diffusing to the image forming module 30 and other areas, and further maintain the temperature of the working environment of the image forming module 30 within an allowable range.
The second air flow path 56 is formed by the area enclosed by the heat insulation board 51 and the side plate 12 of the apparatus body 10, and the heat insulation board 51 may further include a plurality of heat discharging holes 515, so that the hot air of the fixing module 40 is accelerated to flow to the second air flow path 56, thereby preventing the waste heat from accumulating at the turning point of the heat insulation board 51.
The heat dissipation opening 16 is designed above the second airflow channel 56, and the high temperature airflow 565 generated by the fixing module 40 in the thermal fixing step can be directly guided to the heat dissipation opening 16 by using the hot air rising principle to dissipate heat, wherein the heat dissipation opening 16 is arranged in the structure of the side plate 12 by a built-in design, and the heat dissipation opening 16 with a large area is used to replace a plurality of well-known heat dissipation holes arranged on the side plate 12, so that the integrity of the side plate 12 can be maintained.
Further, the copying and scanning module 20 may further be designed with a lifting hole 22 structure of a hidden handle at a position corresponding to the heat dissipation opening 16, and in practice, the lifting hole 22 is designed to be arc-shaped, which not only has the technical effect of accelerating the guiding out of the high-temperature air flow 565, but also facilitates the user to effectively buckle and open the scanning module 20, so as to facilitate the processes of repairing or replacing the components of the copier 100.
However, the heat dissipation and flow guiding structure 50 of the present invention is found by experimental test results: when the fixing module 40 is continuously operated for 2 hours, the temperature of the inner side of the thermal insulation plate 51 is between 165 ℃ and 185 ℃, the temperature measured at the detection point of the heat dissipation opening 16 is between 70 ℃ and 80 ℃, and the temperature detected around the image forming module 30 is between 45 ℃ and 50 ℃. Experiments prove that the heat dissipation and flow guiding structure 50 of the present invention can indeed block the high temperature air flow 565 outside the first air flow channel 55 by means of the heat insulation air curtain 555, so as to avoid affecting key components such as the image forming module 30.
Furthermore, as shown by the measured result of the heat dissipation opening 16, the heat dissipation and flow guiding structure 50 of the present invention can still have the capability of rapidly guiding the high temperature air flow 565 without the device such as a fan, so as to save the configuration of the components such as the fan, and to save the related cost such as the material and energy consumption of the components.
However, if the copier 100 needs to operate for a longer continuous operation time, the fan may be disposed at the heat dissipation opening 16, and the air flow inside the second air flow channel 56 is guided by the air suction principle to generate forced convection, so as to accelerate the guiding out of the high temperature air flow 565, thereby further improving the heat dissipation efficiency.
The copier of the invention hides the heat dissipation hole in the device body by means of the hidden design to maintain the integrity and the aesthetic property of the outer surface of the device, and quickly guides out the high temperature generated by the image fixing module by the flow guide design of the heat dissipation flow guide structure to avoid the image forming module from being influenced by the high temperature, thereby having the aesthetic property of the device and meeting the heat dissipation function.
The above-described embodiments are only for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to put them into practice, and are not to be construed as limiting the scope of the present invention, and variations or modifications may be made on the spirit of the present invention disclosed therein without departing from the scope of the present invention claimed in the claims.
