Description

Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to a non-contact infrared focusing heater. Background Technology

[0002] Infrared focusing heating technology has advantages such as speed, efficiency, and energy saving, and is widely used in industrial heating. Infrared focusing heaters typically use a concentrator to focus infrared energy and directly irradiate it onto the object to be heated.

[0003] Existing infrared focusing heaters, when heating products, also heat the lamp housing and the internal air. The air then transfers heat outwards. In situations where localized heating of the product is necessary, but other parts cannot be heated (e.g., heating adhesive strips for battery electrodes), existing infrared focusing heaters often result in heating unwanted parts of the product, affecting product quality. Furthermore, if the equipment stops unexpectedly and the product is not removed promptly, the heat in the air cannot dissipate quickly, and the hot air will continue to heat the product, causing damage. In addition, the surrounding hot air and excessively high lamp housing temperatures pose a risk of injury. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a non-contact infrared focusing heater, which can cool the air inside and around the heater without affecting the heating effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a non-contact infrared focusing heater, including a lamp housing, an infrared heating tube, and a focusing plate. One side of the lamp housing is recessed to form an accommodating space, and the open end of the accommodating space is a light outlet. The infrared heating tube and the focusing plate are both installed in the accommodating space of the lamp housing, and the infrared heating tube is located between the focusing plate and the light outlet. The lamp housing is provided with two water inlets and outlets for cooling water and at least two air inlets. The lamp housing is provided with a water channel that connects the two water inlets and the air inlets that are connected to the accommodating space of the lamp housing.

[0006] Furthermore, the two water inlets are located on the lamp housing near both ends of the infrared heating tube.

[0007] Furthermore, one of the air connection points is connected to compressed air, and the other is connected to an exhaust fan.

[0008] Furthermore, all of the air connection connectors are connected to an exhaust fan.

[0009] Furthermore, the gas connectors are located on the lamp housing near both ends of the infrared heating tube.

[0010] Furthermore, the heater is provided with two gas connection connectors, both of which are located on the lamp housing near one end of the infrared heating tube, and are respectively located on both sides of the end of the infrared heating tube on the lamp housing.

[0011] Furthermore, the heater is provided with four air passage connectors, which are arranged in pairs on the lamp housing near the two ends of the infrared heating tube. The air passage connectors on the same end of the lamp housing are respectively located on both sides of the end of the infrared heating tube. The two air passage connectors at one end of the lamp housing are connected to compressed air, and the two air passage connectors at the other end are connected to a fan.

[0012] Furthermore, the heater is provided with four gas connection connectors, which are arranged in pairs on the lamp housing near the two ends of the infrared heating tube. The gas connection connectors on the same end of the lamp housing are respectively located on both sides of the end of the infrared heating tube. All four gas connection connectors are connected to a fan.

[0013] Furthermore, the heater is provided with four air passage connectors, which are arranged in pairs on the lamp housing near the two ends of the infrared heating tube. The air passage connectors on the same end of the lamp housing are respectively located on both sides of the end of the infrared heating tube. The two air passage connectors at one end of the lamp housing are blocked, and of the two air passage connectors at the other end, one is connected to compressed air and the other is connected to a fan.

[0024] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art should fall within the protection scope of this utility model.

[0025] Please refer to the following: Figures 1 to 6 This is a preferred embodiment of the present invention. The non-contact infrared focusing heater includes a lamp housing 1, an infrared heating tube 2, and a focusing plate 3. A recessed space 11 is formed on one side of the lamp housing 1. The open end of the space 11 is the light outlet. The infrared heating tube 2 and the focusing plate 3 are both installed within the space 11 of the lamp housing 1, with the infrared heating tube 2 located between the focusing plate 3 and the light outlet. The lamp housing 1 is provided with two water inlets and outlets 4 for cooling water and at least two air inlets. A water channel is provided inside the lamp housing 1, connecting the two water inlets 4. The air inlets are connected to the space 11 of the lamp housing 1.

[0026] The heater of this utility model has a water connector 4 and a water channel on the lamp housing 1, which can reduce the temperature of the lamp housing 1 by water cooling. At the same time, an air connector is provided on the lamp housing 1, which can reduce the temperature of the lamp housing 1 and the accommodating space 11 by air cooling, thereby making the equipment safer, producing better products, and reducing the probability of damage during product production.

[0027] Two water inlets 4 are connected to a chiller (not shown in the figure), allowing water to enter and exit the lamp housing 1 respectively. The cooling water flows within the lamp housing 1, carrying away heat and thus cooling the lamp housing 1. In this embodiment, the two water inlets 4 are located on the lamp housing 1 near both ends of the infrared heating tube 2. Inside the lamp housing 1, above the infrared heating tube 2, are a first water channel 6a and a second water channel 6b. The first and second water channels 6a and 6b extend parallel to each other along the length of the infrared heating tube 2, corresponding to positions on either side of the infrared heating tube 2. The first and second water channels 6a and 6b are connected by two third water channels 6c, which are respectively connected to the two water inlets 4. In this way, the cooling water can flow along the length of the infrared heating tube 2 within the lamp housing 1, effectively carrying away heat from the lamp housing 1. It is understood that the path design of the water channel inside the lamp housing 1 is not limited to the above-described implementation method, and can also be in other ways. For example, the water channel can be designed to be meandering along the length of the infrared heating tube 2, as long as the heat of the lamp housing 1 can be carried away by the flow of cooling water.

[0028] One of the aforementioned air connectors can be connected to compressed air, and the other can be connected to an exhaust fan (not shown in the figure), allowing air to be drawn in and drawn out simultaneously, or all air connectors can be connected to an exhaust fan, allowing air to flow in the housing space 11 of the lamp housing 1, thereby removing heat from the housing space 11 and the lamp housing 1.

[0029] In one embodiment, the gas connectors are located on the lamp housing 1 near both ends of the infrared heating tube 2. In another embodiment, the heater has two gas connectors, both located on the lamp housing 1 near one end of the infrared heating tube 2, and corresponding to the positions on both sides of the end of the infrared heating tube 2 on the lamp housing 1. In this embodiment, the heater has four gas connectors 5a, 5b, 5c, and 5d, arranged in pairs on the lamp housing 1 near both ends of the infrared heating tube 2, and the gas connectors 5a and 5b (5c and 5d) on the same end of the lamp housing 1 are respectively located on the positions on both sides of the end of the infrared heating tube 2 to achieve sufficient ventilation. Please refer to the following: Figure 7 Depending on the situation, the heater has several ventilation methods.

[0030] like Figure 7 As shown in (a), two air connectors 5a and 5b at one end of the lamp housing 1 are connected to compressed air, and two air connectors 5c and 5d at the other end of the lamp housing 1 are connected to an exhaust fan. Air can flow within the accommodating space 11 along the length of the infrared heating tube 2, thereby effectively removing heat from the accommodating space 11 and the lamp housing 1. The direction of air flow is as follows: Figure 7 The direction of the arrow in (a). Figure 7The arrow in (a) only indicates one implementation method. Of course, the air inlet / exhaust methods of the air connectors at both ends of the lamp housing 1 can be interchanged (i.e., air connectors 5c and 5d are connected to compressed air, and air connectors 5a and 5b are connected to the exhaust fan). In this case, the air flows towards... Figure 7 The flow is in the opposite direction of the arrow in (a).

[0031] like Figure 7 As shown in (b), all four air duct connectors 5a, 5b, 5c, and 5d are connected to an exhaust fan. Hot air can flow along the length of the infrared heating tube 2 within the accommodating space 11 towards the four air duct connectors 5a, 5b, 5c, and 5d at both ends of the lamp housing 1, and be extracted, thus effectively removing heat from the accommodating space 11 and the lamp housing 1. The direction of airflow is as follows: Figure 7 The direction of the arrow in (b).

[0032] like Figure 7 As shown in (c), the two gas line connectors 5c and 5d located at one end of the lamp housing 1 are blocked, and of the two gas line connectors 5a and 5b at the other end of the lamp housing 1, one of them ( Figure 7 (c) shows the air connector 5b) which connects to compressed air, and the other ( Figure 7 As shown in (c), air connector 5a) connects to the exhaust fan. Air can flow in the accommodating space 11 along the length of the infrared heating tube 2. Simultaneously, air can also flow radially from one side of the infrared heating tube 2 to the other, thus effectively removing heat from the accommodating space 11 and the lamp housing 1. The airflow direction is as follows: Figure 7 The direction of the arrow in (c). Figure 7 The arrow in (c) only indicates one implementation method. Of course, the air inlet / outlet methods of the air connectors can be interchanged (i.e., air connectors 5c and 5d are blocked, air connector 5a is connected to compressed air, and air connector 5b is connected to the exhaust fan). In this case, the air flows towards... Figure 7 The flow is in the opposite direction of the arrow in (c); in addition, it can also make the original Figure 7 In section (c), the two air passage connectors 5c and 5d that are blocked are one for air intake and one for air extraction. Blocking the two original air passage connectors 5a and 5b that are for air intake / extraction can also achieve the purpose of heat dissipation.

[0033] In this embodiment, the heater also includes a thermocouple 8, which is a K-type thermocouple mounted on the surface of the lamp housing 1 to detect the temperature of the lamp housing 1. The thermocouple 8 allows for real-time monitoring of the lamp housing 1 temperature, enabling better control of the equipment temperature and ensuring safety.

[0034] The aforementioned heater emits infrared light from the infrared heating tube 2 through the light outlet of the lamp housing 1, and focuses it onto the part of the product that needs to be heated through the focusing sheet 3, thereby achieving non-contact heating of the product. The heater dissipates heat from the lamp housing 1 and the housing space 11 of the lamp housing 1 simultaneously through both water cooling and air cooling, which can cool the air inside the heater and the surrounding air without affecting the heating effect, thus preventing damage to the product and operators.

[0035] The above embodiments are merely preferred embodiments of the present utility model, but the implementation of the present utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered as equivalent substitutions and shall be included within the protection scope of the present utility model.
