TECHNICAL FIELD
[0001] The utility model relates to machine tool technical field, concretely is a machine tool heat dissipation assembly. BACKGROUND
[0002] Numerical control machine tool is the abbreviation of digital control machine tool, and it is an automatic machine tool with a program control system. The control system can logically process the program with control code or other symbol instructions, and translate it into code numbers. Through the information carrier, the numerical control device is input. After operation processing, various control signals are sent out by the numerical control device to control the action of the machine tool. According to the shape and size required by the drawing, the parts are automatically processed. Numerical control machine tool belongs to precision machining machinery. Generally, the electric control box of numerical control machine tool is closed. However, the heat dissipation effect of closed electric control box is not very good. In summer, the temperature is too high, which may cause damage or insensitivity of components, causing trouble to production.
[0003] In order to prevent the internal components from overheating and overloading, the existing machine tool adopts heat dissipation groove and installs fan to increase the internal air circulation and accelerate the heat exhaust rate, so as to achieve the purpose of cooling and heat dissipation. Although this method can accelerate the dispersion of hot air, the heat generated by the machine tool during high frequency work is very large. Only relying on the fan to blow the outside fresh air, the fresh air will quickly warm up and assimilate heat when it enters the machine tool and is affected by the temperature transmission of high heat accumulation gas, so that the single fan blowing heat dissipation is difficult to effectively cool the machine tool during high frequency work.
[0004] As the disclosure document with application number 201810625825.0, a machine case heat dissipation assembly for numerical control machine tool is disclosed. The heat dissipation assembly has reasonable structure, effectively cools the working elements in the numerical control machine tool, improves the service life of the machine tool, and has high practical value. However, the machine tool heat dissipation assembly is consistent with the above problems, and a single fan is used to blow the new air flow to dissipate heat, which is difficult to ensure that the machine tool with high heat generated during high frequency work is fully and effectively cooled, which may still cause the internal temperature to be too high and the components to be overheated and damaged.
[0005] Therefore, in view of the above problems, the existing structure is improved, and a machine tool heat dissipation assembly is provided. Utility model content
[0006] The utility model aims at providing a machine tool heat dissipation assembly to solve the problems in the above background.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a machine tool heat dissipation assembly, comprising a machine tool body, with a back panel door rotatably mounted on both the left and right ends of the front surface of the machine tool body, a liquid storage box fixedly mounted on the lower center of the side of the back panel door near the interior of the machine tool body, and air boxes fixedly mounted on both the left and right sides of the back panel door and the liquid storage box, with an air groove on the rear side of the air box surface, a baffle plate fixedly mounted on the middle of the inner surface of the liquid storage box, a submersible pump fixedly mounted on the right side of the inner surface of the liquid storage box, a semiconductor cooling chip fixedly mounted on the lower left side of the inner surface of the liquid storage box, and a flow pipe fixedly connected to the right end of the submersible pump through the liquid storage box.

[0014] Preferably, the filter plate consists of a perforated plate and a filter screen inside the perforated body, and a fan is mounted on the inner surface of the fixing cover using a bracket.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model, through the arrangement of a liquid storage box, air box, air groove, baffle plate, submersible pump, semiconductor cooling chip and flow pipe, allows the cooled low-temperature air to be blown into the machine tool body through the air groove, which can cool the electrical components more quickly and efficiently, and the cooling and heat dissipation effect is better, thereby greatly improving the cooling and heat dissipation efficiency and fully avoiding the situation of overheating and overload of internal electrical components caused by high-frequency use of the machine tool;

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figs. 1-3 As shown, a machine tool heat dissipation assembly includes a machine tool body 1. A back panel door 2 is rotatably mounted on both the left and right ends of the front surface of the machine tool body 1. A liquid storage box 3 is fixedly mounted on the lower center of the surface of the back panel door 2 near the interior of the machine tool body 1. Air boxes 4 are fixedly installed on both the left and right sides of the surface of the back panel door 2 and the liquid storage box 3. An air groove 5 is opened on the rear side of the surface of the air box 4. A baffle plate 6 is fixedly mounted on the middle of the inner surface of the liquid storage box 3. A submersible pump 7 is fixedly mounted on the right side of the inner surface of the liquid storage box 3. A semiconductor cooling chip 8 is fixedly mounted on the lower left side of the inner surface of the liquid storage box 3. A flow pipe 9 is fixedly connected to the right end of the submersible pump 7 through the liquid storage box 3. Both the liquid storage box 3 and the flow pipe 9 are filled with coolant.
[0024] By adopting the above technical solution, the semiconductor cooling chip 8 lowers the temperature of the coolant inside the liquid storage box 3, which is then pumped into the flow pipe 9 by the submersible pump 7. The low-temperature coolant flowing inside the flow pipe 9 exchanges heat with the air inside the air box 4 as it flows through a section of the pipe, thereby making the air temperature inside the air box 4 lower than the temperature of the fresh air flowing outside. The cooled air is then blown into the machine tool body 1 through the air groove 5, which can cool the electrical components more quickly and efficiently, resulting in better cooling and heat dissipation.
[0025] Furthermore, the flow pipes 9 all pass through the air boxes 4 on both the left and right sides, and the section of the flow pipe 9 inside the air box 4 is set as an "S" shaped pipe.
[0026] By adopting the above technical solution, the "S"-shaped pipeline makes the flow pipe 9 longer inside the air box 4, and the air flowing inside the air box 4 is cooled more thoroughly.
[0027] Furthermore, the lower left end of the flow tube 9 is connected to the upper left side of the inner surface of the liquid storage box 3, and the water-permeable holes on the surface of the baffle plate 6 are located in the lower middle part of the plate.
[0028] By adopting the above technical solution, the lower left end of the flow pipe 9 and the liquid storage box 3 form a closed loop channel, so that the coolant can continuously circulate under the suction of the submersible pump 7.
[0029] After heat exchange, the coolant can flow back into the storage box 3 and be cooled again by the semiconductor cooling chip 8.
[0030] Since the return port of the flow pipe 9 is at the top and the water permeation hole of the baffle plate 6 is at the bottom, the two are not on the same horizontal level. As a result, the warm coolant returning is blocked by the baffle plate 6 and will not immediately rush to the right to be sucked in by the submersible pump 7. Instead, it will be cooled down by the semiconductor cooling chip 8 and then flow into the right side for secondary suction through the water permeation hole below, ensuring that the coolant is at a sufficiently low temperature during circulation.
[0031] Furthermore, a heat-conducting plate 10 is fixedly installed in the middle of the surface of the back door 2. The heat-conducting plate 10 is a copper plate embedded in the middle inner wall of the back door 2.
[0032] By adopting the above technical solution, the heat-conducting plate 10 can continuously absorb the heat emitted from the air inside the machine tool body 1 and actively exchange heat with the outside air.
[0033] Furthermore, fins 11 are evenly distributed and fixedly installed on the front side of the heat-conducting plate 10, and heat dissipation mesh holes 12 are opened on both the left and right sides of the outer surface of the machine tool body 1.
[0034] By adopting the above technical solution, the heat dissipation mesh 12 ensures air circulation inside the machine tool body 1, allowing hot air to be discharged.
[0035] Furthermore, a fixing cover 13 is fixedly installed on the front side of the outer surface of the back door 2, and four fixing covers 13 are symmetrically installed on the left and right sides along the middle of the surface of the back door 2.
[0036] The rear opening of the fixed cover 13 passes through the back box door 2 and communicates with the inside of the air box 4. A dust filter plate 14 is installed on the front surface of the fixed cover 13. The dust filter plate 14 is composed of a perforated plate and a filter screen inside the perforated body. A fan 15 is installed on the inner surface of the fixed cover 13 using a bracket.
[0037] By adopting the above technical solution, the dust filter plate 14 prevents dust from entering when the fan 15 draws in air;
[0038] Fan 15 can draw in fresh air from the outside, which passes through the inside of the air box 4 and is blown into the machine tool body 1 through the air groove 5, accelerating the air circulation inside the machine tool body 1. The fresh air can not only cool down the electrical components, but also blow out the hot air through the heat dissipation mesh 12.
[0039] Working principle: When using this machine tool heat dissipation component, firstly, when the machine tool body 1 operates at low frequency, the heat conduction plate 10 can continuously absorb the heat dissipated from the air inside the machine tool body 1. The fins 11 increase the contact surface with the outside air, thereby quickly exchanging heat and cooling the internal components. The heat dissipation mesh 12 also ensures normal heat flow and dissipation, allowing for sufficient heat dissipation without the need for other heat dissipation components. However, when the machine tool body 1 operates at high frequency, and the heat conduction plate 10 cannot convert the generated heat in time, the fan 15 and submersible pump 7 are activated. The fan 15 draws in fresh outside air, which passes through the air box 4 and... Air is blown into the machine tool body 1 through the air channel 5, accelerating the air circulation inside the machine tool body 1. Meanwhile, the semiconductor cooling chip 8 lowers the temperature of the coolant inside the liquid storage box 3, which is then pumped into the flow pipe 9 by the submersible pump 7. The low-temperature coolant flowing inside the flow pipe 9 exchanges heat with the air inside the air box 4 as it flows through a section of the pipe inside the air box 4. This causes the air temperature inside the air box 4 to be lower than the temperature of the fresh air flowing outside. At this time, the fan 15 blows the cooler air after heat exchange into the machine tool body 1, which can cool the electrical components more quickly and efficiently. This is the working principle of the heat dissipation component of the machine tool.
