The lamp cover in related technologies is difficult to ensure high uniformity in lateral ventilation speed. The main reason is that the middle of the infrared lamp tube releases more heat energy than the two ends. Therefore, the heat dissipation performance of the lamp cover in related technologies needs to be improved. Utility Model Content

[0006] The first aspect of this application provides an infrared lampshade, including: a lampshade body and a flow equalization plate;

[0007] The flow equalization plate is disposed on the lampshade body and is used to form an air duct;

[0008] The lampshade body has air inlets at both ends along its length, and the flow equalization plate is used to communicate with each of the air inlets.

[0015] Furthermore, the infrared lamp cover is used to install an infrared heating component, which is used to heat the workpiece to be heated. The infrared lamp cover also includes a guide plate, which is disposed on the lamp cover body.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application discloses an infrared lampshade, including a lampshade body 100 and a flow equalization plate 200;

[0039] A flow equalization plate 200 is disposed on the lampshade body 100 and is used to form an air duct 201; air inlets 110 are respectively provided at both ends of the lampshade body 100 along its length, and the flow equalization plate 200 is used to communicate with each air inlet 110; wherein, the flow equalization plate 200 includes a first air outlet 210 and a second air outlet 220 for outputting cooling air, the first air outlet 210 is disposed in the middle of the air duct 201, and the second air outlet 220 is disposed at both ends of the air duct 201, and the air volume of the first air outlet 210 is greater than that of the second air outlet 220.

[0040] In the embodiments of this application, air intake is achieved by providing air inlets 110 at both ends. Cooling air is guided by a flow equalization plate 200 and then discharged using a first air outlet 210 and a second air outlet 220 provided on the flow equalization plate 200. Based on the characteristic that the middle part of the infrared lamp releases more heat energy than the two ends, the air volume of the first air outlet 210 is designed to be larger than that of the second air outlet 220 to achieve a balanced cooling effect and improve heat dissipation performance.

[0041] Understandably, in some embodiments, the air duct 201 of the flow equalization plate 200 is used to uniformly deliver cooling air to the infrared heating component 300 and cool it. Based on this, by specifically designing the first air outlet 210 and the second air outlet 220 for air outlet, and by adaptively adjusting the air volume of the first air outlet 210 and the second air outlet 220 according to the characteristic that the middle part of the infrared heating component 300 releases more heat energy than the two ends, and based on the setting that the air volume of the first air outlet 210 is larger than the air volume of the second air outlet 220, the air volume at the middle position of the flow equalization plate 200 is larger than the air volume at the two ends, so as to cool the infrared heating component 300 as uniformly as possible and improve the heat dissipation performance.

[0042] For example, the infrared heating component 300 is an infrared lamp tube. However, it should be understood that, based on the content disclosed in the embodiments of this application, if those skilled in the art make adaptive and simple improvements without creative effort, so that the resulting infrared lamp cover can be used for uniform heat dissipation in other types of products or other technical fields and achieve the effect of uniform heat dissipation, it should also be considered to fall within the scope of protection of this application.

[0043] The following will combine Figures 1 to 4 The infrared lampshade disclosed in the embodiments of this application will be explained and described in detail.

[0044] It should be understood that in order for the air volume of the first air outlet 210 to be greater than that of the second air outlet 220, the structural design of the first air outlet 210 and the second air outlet 220 is the key to achieving the corresponding functions.

[0045] In this regard, refer to Figure 1 and Figure 2 In some embodiments of this application, the first air outlet 210 and / or the second air outlet 220 are configured as air vent slits, each air vent slit being formed on the flow equalization plate 200 and communicating with the air duct 201. It is understood that using the air vent slit structure as the first air outlet 210 and the second air outlet 220 allows for the adjustment of the air volume while ensuring controllable airflow. This facilitates design, adjustment, and structural fabrication.

[0046] It is understandable that there are various ways to design the specific structure of the air vent slit, and those skilled in the art can design a specific structure according to actual needs and usage scenarios.

[0047] For example, in some embodiments, the number of first air outlets 210 is greater than the number of second air outlets 220; it is understood that by providing a greater number of first air outlets 210, the air volume can be increased. The specific required air volume can be obtained by adjusting the actual number.

[0048] For example, refer to Figure 1 and Figure 2 In some embodiments, the vent size of the first air outlet 210 is larger than that of the second air outlet 220. It is understood that the actual heat radiation from the lamp tube is hotter in the middle than at both ends. Based on this, the slit size of the air outlet on the flow equalization plate 200 for cooling the lamp tube is arranged with a larger size in the middle and smaller sizes at both ends, resulting in a larger airflow volume in the middle than at both ends, achieving balanced cooling. Furthermore, the duct of the air inlet 110 is generally relatively small, resulting in a faster incoming cooling air velocity. The airflow trend from both ends tends to push most of the air towards the middle, which, combined with the slit opening structure of the flow equalization plate 200 (larger size in the middle and smaller size at both ends), results in less airflow resistance in the middle and a larger airflow volume than at both ends.

[0049] In some embodiments of this application, reference is made to Figure 3 The lampshade body 100 also includes a flow equalization cavity 120, the two ends of which are connected to each air inlet 110. The flow equalization cavity 120 is used to evenly output cooling air to the flow equalization plate 200. It can be understood that the flow equalization cavity 120 receives the air input from the air inlets 110, and then outputs it to the first air outlet 210 and the second air outlet 220 respectively through the flow equalization effect. The flow equalization plate 200 then guides and equalizes all the cooling air, thereby ensuring high uniformity of the ventilation velocity of the infrared heating component 300.

[0050] In some embodiments, the flow equalization plate 200 is height-adjustable within the flow equalization cavity 120. It is understood that the height of the flow equalization plate 200 can be adaptively adjusted for different specifications of the infrared heating component 300, thereby adjusting the relative distance between the flow equalization plate 200 and the infrared heating component 300, controlling the cooling effect, and improving the applicability of the infrared lampshade in this application embodiment.

[0051] In some embodiments, the flow equalization plate 200 is disposed within the flow equalization cavity 120 via a common movable connection, thereby having a highly adjustable function.

[0052] In some embodiments of this application, reference is made to Figure 3 The infrared lamp cover is used to mount the infrared heating element 300, which is used to heat the workpiece to be heated. The infrared lamp cover also includes a guide plate 400, which is disposed on the lamp cover body 100. The guide plate 400 is used to guide the cooling air output from the flow equalization plate 200 and acting on the infrared heating element 300, so that the cooling air flows away from the workpiece to be heated. It can be understood that in some embodiments, the flow equalization cavity 120, the flow equalization plate 200 and the infrared heating element 300 are arranged sequentially from top to bottom, and the guide plate 400 is located on the side of the infrared heating element 300. Thus, after the cooling air acts on the infrared heating element 300 from top to bottom, it can be discharged to the outside through the guide plate 400, ensuring uniform cooling. Furthermore, the workpiece to be heated is usually located below the infrared heating element 300 to receive the heating effect. Therefore, the air is guided upward by the guide plate 400 to prevent the discharged hot air from affecting the electrode, thus ensuring the heating quality of the lower electrode.

[0053] Understandably, in order to improve the utilization rate of light and ensure concentrated reflection while meeting a certain energy-gathering effect, a radiating mirror can be installed on the infrared lamp cover.

[0054] Exemplary, in some embodiments, reference is made to Figure 3 The infrared lamp cover also includes a first radiating component 500, which is disposed on at least one surface of the lamp cover body 100 near the workpiece to be heated. It is understood that by disposing of the first radiating component 500 on the surface of the infrared lamp cover near the workpiece to be heated, the light emitted by the infrared heating component 300 is refracted and reflected twice, thereby improving the utilization rate of the light.

[0055] In some embodiments, the first radiating component 500 is a radiating mirror, disposed on both sides of the infrared heating component 300 and located at the bottom of the infrared lamp cover.

[0056] Exemplary, in some embodiments, reference is made to Figure 3The infrared lamp cover also includes a second radiating component 600. The first surface of the guide plate 400 is used for guiding the airflow, and the second radiating component 600 is disposed on the second surface of the guide plate 400 opposite to the first surface. It is understood that, considering that the guide plate 400 is also located on both sides of the infrared heating component 300, the second radiating component 600 can be disposed on the bottom surface of the outer side of the guide plate 400, thereby fully utilizing the secondary refraction and reflection of the light emitted by the infrared heating component 300 and improving the light utilization rate.

[0057] In some embodiments, the top surface of the relatively inner side of the guide plate 400 is used to guide the cooling air away, and the radiating mirror is set on the bottom surface of the relatively outer side of the guide plate 400. When light shines on the surface of the electrode, there will be reflection, and the reflection will be reflected back to the bottom surface of the relatively outer side of the guide plate 400, thereby making full use of the light emitted by the infrared lamp.

[0058] In some embodiments of this application, reference is made to Figure 4 The infrared lamp cover also includes protective support strips 700, which are obliquely spaced on the lamp cover body 100. It is understood that the obliquely spaced protective support strips 700 can, on the one hand, eliminate localized dark marks caused by the protective support strips 700 blocking light, making the radiating carrier heat up more evenly; on the other hand, they can protect the lamp tube during installation and transportation.

[0059] In some embodiments, the protective support strip 700 is the steel wire of the lamp tube cover.

[0060] The infrared lampshade of this application embodiment is described in detail below with a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0061] See Figures 1 to 4 As shown, the infrared lamp cover of this embodiment includes a cold air inlet 110, a lamp cover body 100, a flow equalizer 200, a hot air outlet guide plate 400, a lamp tube cover, and a radiating surface mirror. The flow equalizer 200 is installed in the flow equalization cavity 120 of the lamp cover body 100 to cool the lamp tube. The height of the flow equalizer 200 can be adjusted to accommodate multiple lamp tube models and facilitate replacement and maintenance. The design of the radiating surface mirror allows for secondary refraction and reflection of the light emitted by the infrared lamp tube, improving the light utilization rate. The air inlet 110 has two ends for air intake, which makes the cooling of the lamp tube surface more reasonable and is more in line with the heating characteristics of the infrared lamp tube, which releases more heat energy in the middle than at both ends. The function of the guide plate 400 is to guide the hot air to the back of the radiating surface to prevent the discharged hot air from affecting the heated carrier. The steel wire of the lamp tube cover is designed with an inclined design to eliminate local dark marks caused by the steel wire blocking the light, so that the radiating carrier is heated more evenly and to protect the lamp tube during installation and transportation.

[0062] It should be noted that the air vent slit of the flow equalization plate 200 for cooling the lamp tube is wider in the middle and narrower at both ends. The purpose is to ensure that the air volume of the cold air in the middle is greater than that at both ends, thereby achieving the purpose of balanced cooling. When the cooling air flows from the flow equalization cavity 120 to the air vent slit of the flow equalization plate 200, the air velocity is faster due to the smaller air vent. The airflow trend from both ends is that most of the air is pushed to the middle and concentrated. Combined with the slit opening structure of the flow equalization plate 200, the airflow resistance in the middle is smaller, and the airflow volume is greater than that at both ends.

[0063] The second aspect of this application discloses an infrared heating device, which can be a device that uses infrared lamps for heating. The infrared heating device includes: the infrared lamp cover of the first aspect of this application.

[0064] The production line of the third aspect of this application may be a lithium battery production line, and the production line includes: the infrared heating device of the second aspect of this application.
