[0030] Embodiment

[0031] Please refer to Figs. 1 to 3 The present embodiment provides an infrared module, which comprises a fixed frame 1, an infrared heating plate 2 and a reflecting plate 3. The infrared heating plate 2 is arranged on the side of the fixed frame 1 facing the heating target. The reflecting plate 3 is arranged on the side of the fixed frame 1 away from the heating target. The fixed frame is provided with flow guide holes 12 on both sides in the width direction. The fixed frame is provided with wind barriers 11 on both sides in the width direction of the infrared heating plate.

[0032] In the present embodiment, the infrared module is usually installed between two groups of air knives 4. The airflow of the air knives 4 often rapidly takes away the temperature on the surface of the infrared module, resulting in a large temperature loss of the infrared module, inaccurate temperature measurement, poor heating effect, etc. In order to ensure the heating effect of the infrared module, a wind barrier 11 is arranged on each side of the fixed frame 1 of the infrared module close to the air knives 4, so as to reduce the influence of the airflow of the air knives 4 on the infrared module, improve the internal and external temperature difference of the infrared module, make the temperature measurement more accurate, and thus improve the heating efficiency.

[0033] By arranging the flow guide holes 12 on both sides of the fixed frame 1 in the width direction, heat exchange and cooling of the interior of the infrared module can be achieved, the temperature difference between the interior and exterior of the infrared module is reduced, and the service life of the infrared module is prolonged.

[0034] In an embodiment, the structure of the flow guide hole 12 is improved to ensure the temperature balance of the infrared module. Specifically, the aperture of the flow guide hole 12 gradually decreases from both ends to the middle of the fixed frame 1.

[0035] In the embodiment, in actual application, the temperature of the two ends of the long infrared heating plate 2 is higher than the temperature of the middle part due to the material characteristics and process problems, and the heating is not uniform. Therefore, the flow guide holes 12 are arranged on the side of the fixed frame 1, and the aperture of the flow guide holes 12 gradually decreases from the two ends to the middle of the fixed frame 1, so as to strengthen the heat dissipation of the two ends of the infrared heating plate 2 and weaken the heat dissipation of the middle part of the infrared heating plate 2, thereby realizing more uniform heating of the long infrared heating plate 2.

[0036] In an embodiment, the structure of the flow guide holes 12 is improved to ensure the temperature balance of the infrared module. Specifically, the spacing between the flow guide holes 12 gradually increases from the two ends to the middle of the fixed frame 1.

[0037] In the embodiment, in actual application, the temperature of the two ends of the long infrared heating plate 2 is higher than the temperature of the middle part due to the material characteristics and process problems, and the heating is not uniform. Therefore, the flow guide holes 12 are arranged on the side of the fixed frame 1, and the spacing between the flow guide holes 12 gradually increases from the two ends to the middle of the fixed frame 1, so as to strengthen the heat dissipation of the two ends of the infrared heating plate 2 and weaken the heat dissipation of the middle part of the infrared heating plate 2, thereby realizing more uniform heating of the long infrared heating plate 2.

[0038] In an embodiment, the structure of the flow guide holes 12 is improved to ensure the temperature balance of the infrared module. Specifically, the flow guide holes 12 are long circular holes.

[0039] In the embodiment, in order to ensure the flow guide heat dissipation effect, the flow guide holes 12 can be long circular holes, which can provide larger ventilation capacity. The length direction of the long circular holes is consistent with the length direction of the fixed frame 1.

[0040] In an embodiment, the structure of the flow guide holes 12 is improved to ensure the temperature balance of the infrared module. Specifically, the aperture of the flow guide holes 12 is d, wherein 2mm < d < 12.5mm.

[0041] In the embodiment, in order to avoid accidents caused by accidental insertion of fingers into the interior of the infrared module, the aperture of the flow guide holes 12 is not greater than 12.5mm, and in order to avoid blockage by foreign matter, the aperture of the flow guide holes 12 is not less than 2mm.

[0042] In an embodiment, the structure of the reflection plate 3 is improved to ensure the heating efficiency of the infrared module. Specifically, the reflection plate 3 is a stainless steel plate.

[0043] In the embodiment, the reflecting plate 3 is a stainless steel plate, which has good oxidation resistance at high temperature and can ensure the structural strength.

[0044] The stainless steel plate is fixed to the side of the fixing frame 1 away from the heating target through the fixing piece 31, and the stainless steel plate can well reflect the heat radiated by the infrared heating plate, thereby ensuring the heating efficiency of the infrared module.

[0045] In an embodiment, the material of the fixing frame 1 is improved to facilitate the processing of the fixing frame 1.

[0046] In the embodiment, the stainless steel has good oxidation resistance at high temperature and can ensure the structural strength.

[0047] In an embodiment, the structure of the fixing frame 1 is improved to facilitate the adaptive adjustment of the air baffle 11 to the air knife with different air outlet angles.

[0048] In the embodiment, the air baffle 11 cannot be too long, otherwise the air baffle 11 will cause air turbulence and make the heating target shake easily.

[0049] Specifically, a limiting screw can be arranged on the fixing frame, and a sliding groove corresponding to the limiting screw can be arranged on the air baffle.

[0050] As can be seen from the above description, the infrared module with the air baffle has the advantages of reasonable structure, which can reduce the influence of the air knife airflow on the surface temperature of the module, thereby improving the heating efficiency.

[0051] The utility model also relates to a kind of coating oven, including the infrared module as above. Coating oven includes at least two groups of air knives, and infrared module is equipped between adjacent two groups of air knives.

[0052] The coating oven has the same advantages as the above-mentioned infrared module compared to the prior art, and the description is not repeated.
