Description

Technical Field

[0001] This utility model relates to the field of high-temperature box furnace technology, and in particular to a heat insulation and cooling structure for a control module of a high-temperature box furnace. Background Technology

[0002] High-temperature box furnaces are commonly used equipment in industrial heat treatment processes. The control module is responsible for monitoring and adjusting key parameters such as temperature and heating time inside the furnace to ensure that the entire heat treatment process meets the preset process requirements. In order to avoid damage to the electronic components in the control module due to direct exposure to high temperature environment, these control modules are usually not installed in the heating zone of the high-temperature box furnace, but in a separate control cabinet. This control cabinet is usually placed next to the furnace body, which is convenient for operation and away from the high-temperature area.

[0003] However, when the box furnace heats the products, the temperature inside the furnace will rise significantly. If the insulation performance of the control cabinet itself is insufficient, the heat conducted from the furnace will cause the temperature inside the control cabinet to rise. The system components inside the control cabinet will be at risk of high temperature and damage, affecting the accuracy of the adjustment of important parameters such as temperature and heating time, and thus affecting the normal use of the high-temperature box furnace. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a heat insulation and cooling structure for a control module of a high-temperature box furnace, including an outer shell 1, an inner shell 9, a control cabinet 2, and a water-circulating chiller 6. It also includes two open-type shells, with the inner shell 9 fitted inside the outer shell 1, and a U-shaped cooling water cavity 12 formed between the two shells. The U-shaped cooling water cavity 12 is filled with cooling water. Several heat sinks 7 (such as copper sheets) are fixedly connected to the inner wall of the inner shell 9, contacting the surface of the control cabinet 2. Cabinet 2 is detachably inserted into the inner shell 9. One end of the water outlet pipe 3 is fixedly connected to the top side of the cooling water chamber 12, and one end of the water inlet pipe 4 is fixedly connected to the bottom side of the cooling water chamber 12. The other end of the water inlet pipe 4 is fixedly connected to the input end of the booster pump 5, and the other end of the water outlet pipe 3 and the output end of the booster pump 5 are fixedly connected to the water circulation chiller 6. Several heat dissipation slots 201 are provided on both sides of the control cabinet 2. A ventilation pipe 10 is fixedly connected between the outer shell 1 and the back of the inner shell 9, and a cooling fan 11 is fixedly installed inside the ventilation pipe 10. First, the cooling water circulates in a closed loop composed of the water circulation chiller 6, the booster pump 5, the water inlet pipe 4, and the water outlet pipe 3. The booster pump 5 pushes the cooling water through the cooling water chamber 12. As the water flows through the cooling water chamber, it absorbs the heat transferred from the control cabinet 2 and is then cooled by the water circulation chiller 6, thus forming a continuous heat removal process. The heat sink 7 greatly increases the heat conduction area, enabling the heat generated by the control cabinet 2 to be transferred to the cooling water in the cooling water chamber 12 more efficiently, accelerating the heat transfer. Secondly, when the cooling fan 11 is working, it can promote airflow between the inner and outer shells, further helping the control cabinet 2 to dissipate heat. The multiple heat dissipation slots 201 opened on both sides of the control cabinet 2 also help improve the airflow inside the cabinet and improve the heat dissipation effect.

[0029] This device effectively reduces the temperature inside the control cabinet by combining a water cooling system, high-efficiency heat sinks, and forced air convection, ensuring that the control module can operate within a safe operating temperature range and avoiding damage or performance degradation caused by overheating.

[0030] Specifically, such as Figure 1 and Figure 5 As shown, the inner housing 9 has a connecting groove 901 around its front end. The control cabinet 2 is fixedly connected around its perimeter with a fixing seat 8 that mates with the connecting groove 901. The fixing seat 8 and the connecting groove 901 are fixedly connected by bolts 13, so that the control cabinet 2 is stably installed inside the inner housing 9 and is easy to disassemble, maintain or replace.

[0031] Working principle: When in use, the booster pump 5 pushes the cooling water through the cooling water chamber 12. When the water flows through the cooling water chamber, it absorbs the heat transferred from the control cabinet 2, and then it is cooled by the water circulation chiller 6, thus forming a continuous heat removal process. The heat sink 7 greatly increases the heat conduction area, so that the heat generated by the control cabinet 2 can be transferred to the cooling water in the cooling water chamber 12 more efficiently, accelerating the heat transfer.

[0032] Secondly, when the cooling fan 11 is working, it can promote airflow between the inner and outer shells, further helping the control cabinet 2 to dissipate heat. The multiple heat dissipation slots 201 on both sides of the control cabinet 2 also help improve airflow inside the cabinet and enhance the heat dissipation effect.

[0033] By combining a water-cooling system, high-efficiency heat sinks, and forced air convection, the temperature inside the control cabinet is effectively reduced, ensuring that the control module can operate within a safe operating temperature range and avoiding damage or performance degradation due to overheating.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
