Description

Technical Field

[0001] The utility model relates to the field of printing production, and more specifically, to a controller of digital printing equipment. Background Art

[0002] Digital printing equipment is increasingly being used, and its performance requirements are becoming increasingly higher. As the core component of digital printing equipment, the performance of the controller directly affects the operation of the entire equipment. However, since the controller generates a lot of heat during operation, if the heat cannot be dissipated in a timely and effective manner, the controller temperature will be too high, affecting its normal operation and even causing damage to the equipment.

[0003] The traditional heat dissipation method mainly relies on the combination of cooling fins and cooling fans. The cooling fins conduct the heat generated by the controller body into the air by increasing the heat dissipation area; the cooling fan takes away the heat on the fins by accelerating the air flow. However, this heat dissipation method often fails to meet the demand for heat dissipation when facing high-load work, especially in high-temperature environments, where the controller temperature is prone to be too high, affecting equipment performance. For example, patent No. CN202320261543.3 discloses a controller housing cooling fin. This heat dissipation method, which is simply based on the action of fins and natural wind, often fails to meet the demand for heat dissipation when facing high-load work.

[0004] Therefore, how to dissipate heat from the controller of digital printing equipment more effectively has become a problem that needs to be solved urgently. Utility Model Content

[0025] Figure 1 A controller of a digital printing device of the utility model is shown, including a controller body 1, a group of heat dissipation fins 2 arranged at the heat source of the controller body 1, a heat dissipation fan Ⅰ3 is arranged at the other end of the heat dissipation fins 2, and also includes: a water cooling device arranged between the heat dissipation fins 2; wherein the water cooling device is tightly fitted with the heat dissipation fins 2.

[0026] Working principle:

[0027] First, the controller body 1 generates heat when performing various printing tasks and data processing. In order to effectively manage this heat, the heat sink 2 is set at the heat source of the controller body 1. The heat sink 2 is made of a material with good thermal conductivity, which can quickly absorb the heat generated by the controller body 1 and conduct it to its surface.

[0028] Next, the cooling fan I3 is located at the other end of the cooling fin 2. When the cooling fan I3 is turned on, it accelerates the air flow. When the air passes through the cooling fin 2, it takes away the heat on the fin and dissipates it into the surrounding environment. This process further improves the heat dissipation efficiency by means of convection heat dissipation.

[0029] However, under high-load operation or high-temperature environment, the heat dissipation requirements cannot be met by relying solely on the heat dissipation fins 2 and the heat dissipation fan Ⅰ3. Therefore, a water cooling device is provided. The water cooling device fits tightly with the heat dissipation fins 2, and the heat on the heat dissipation fins 2 is taken away by the circulating coolant. During the circulation process, the coolant continuously absorbs the heat on the fins and brings it to the cold end of the water cooling device for heat dissipation, thereby achieving a more efficient heat dissipation effect.

[0030] In the above scheme, the water cooling device includes: a water cooling pipe 4 having a plurality of curved structures, a water tank 5 connected to the water cooling pipe 4, a cooling fan II 7 arranged on the water tank 5, and a circulating pump 6 arranged on the passage of the water cooling pipe 4, wherein the water tank 5, the water cooling pipe 4 and the circulating pump 6 form a water cooling circulation passage;

[0031] Among them, the water cooling pipe 4 is located between each heat dissipation fin 2 and is tightly fitted with the heat dissipation fin 2, and the circulating pump 6 is connected to the controller body 1 through a fixing mechanism. With this technical solution, the water cooling device mainly consists of a water cooling pipe 4 with multiple curved structures, the water cooling pipe 4 is connected to the water tank 5 through the water inlet pipe and the water outlet pipe at both ends, a cooling fan II 7 arranged on the water tank 5, and a circulating pump 6 arranged on the water cooling pipe 4 passage. These components together construct a complete water cooling circulation passage, realizing efficient heat dissipation of the controller. The water cooling pipe 4 has multiple curved structures. This design not only increases the heat dissipation area, but also enables the water cooling pipe 4 to fit better between the heat dissipation fins 2. The water cooling pipe 4 fits tightly with the heat dissipation fins 2, which can ensure that heat can be quickly transferred from the heat dissipation fins 2 to the coolant, thereby improving the heat dissipation efficiency. The water tank 5 is connected to the water cooling pipe 4 as the storage and circulation center of the coolant. The circulating pump 6 is arranged on the water cooling pipe 4 passage, and the construction of the water cooling circulation passage is realized by driving the flow of the coolant. The circulation pump 6 is connected to the controller body 1 through a fixing mechanism, wherein the fixing mechanism is screw fixing or snap-on fixing. When screw fixing is adopted, a threaded hole or a mounting plate is reserved on the controller body. The circulation pump is fixed to the controller body with screws. Its stability and reliability during operation are ensured. The cooling fan II 7 is arranged on the water tank 5, and its function is to take away the heat in the water tank 5 and dissipate it to the surrounding environment by accelerating the air flow. This design further improves the heat dissipation effect of the water cooling device and ensures the temperature stability of the controller when working under high load.

[0032] In the above solution, each heat sink fin 2 is provided with a plurality of micro through holes 10. With this technical solution, the micro through holes 10 can also increase the surface area of ​​the heat sink fin 2 and improve the heat dissipation efficiency. By providing the micro through holes 10, the effective heat dissipation area of ​​the heat sink fin 2 is increased, so that more heat can be dissipated through the heat sink fin 2.

[0033] In the above solution, a plurality of heat dissipation holes 8 are provided on both sides of the controller body 1 and are connected to the inside of the controller body 1. With this technical solution, the design of the heat dissipation holes 8 increases the heat dissipation area of ​​the controller body 1. By providing a plurality of heat dissipation holes 8 on both sides of the controller body 1, the heat inside the controller can be dissipated to the external environment more quickly through these holes. This effectively improves the heat dissipation efficiency and reduces the heat accumulation generated by the controller during operation.

[0034] In the above scheme, a cooling fan III 9 is arranged inside one of the heat dissipation holes 8, and a heat dissipation channel is constructed in the space of the controller body 1 by cooperating with the heat dissipation holes 8 on both sides and the heat dissipation fan III 9. With this technical scheme, a high-efficiency heat dissipation channel is constructed by arranging a cooling fan III 9 inside one of the heat dissipation holes 8 and cooperating with the heat dissipation holes 8 on both sides. This technical scheme further improves the heat dissipation effect of the controller and ensures the stability and reliability of the device when working under high load.

[0035] The function of the cooling fan III 9 is to actively guide the air flow, and by accelerating the air flow speed between the cooling holes 8, the heat inside the controller body 1 is quickly taken out and dissipated to the external environment. Compared with natural convection cooling, this active cooling method can more efficiently remove heat and significantly reduce the temperature of the controller body 1.

[0036] In the above solution, the water cooling tube 4 is configured as a copper tube, and the contact surface between the water cooling tube 4 and the heat sink fin 2 is filled with silicone grease. With this technical solution, first of all, the copper tube has significant advantages as the choice of water cooling tube 4. Copper has good thermal conductivity and can quickly transfer the heat on the heat sink fin 2 to the coolant, thereby improving the efficiency of the entire heat dissipation system. In addition, the copper tube also has high corrosion resistance and wear resistance, which can ensure that the water cooling system maintains stable performance during long-term operation.

[0037] Secondly, the method of filling the contact surface of the water cooling tube 4 and the heat dissipation fin 2 with silicone grease further enhances the heat dissipation effect. As an excellent heat conducting medium, silicone grease can fill the tiny gap between the water cooling tube 4 and the heat dissipation fin 2, reduce thermal resistance, and enable heat to be transferred from the heat dissipation fin 2 to the water cooling tube 4 more smoothly. This can not only improve the heat dissipation efficiency, but also help to extend the service life of the heat dissipation component.

[0038] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
