Description

Technical Field

[0001] The utility model relates to a motor, in particular to a high-efficiency explosion-proof brake motor, belonging to the technical field of motors. Background Art

[0002] Explosion-proof brake motor is a special motor used in flammable and explosive places. It has high safety and reliability. It adopts special structure and protective measures inside to prevent sparks or high temperature generated inside the motor from causing combustion or explosion of external explosive gas mixture. It is often used in dangerous environments, such as petroleum, chemical, coal mining and other industries to ensure the safety of personnel and equipment. Due to its wide applicability, it is sometimes used in some relatively high temperature environments.

[0003] When the explosion-proof brake motor is in use, it generates heat. Excessive heat will affect the internal resistance of the explosion-proof brake motor, resulting in increased power loss, which in turn reduces its efficiency. When the explosion-proof brake motor is in use, it generally dissipates heat naturally through the surface area of ​​the motor casing, or by installing a fan to promote air flow and accelerate heat dissipation. However, when the explosion-proof brake motor is used in some high-temperature environments, natural heat dissipation and fan heat dissipation are insufficient to quickly cool down the explosion-proof brake motor. When the heat dissipation structure is not sufficient to dissipate the heat generated by the motor itself, the motor will gradually increase its own temperature while affecting the efficiency of the motor itself.

[0004] Therefore, there is an urgent need to improve high-efficiency explosion-proof brake motors to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figure 1-Figure 7 As shown, the high-efficiency explosion-proof brake motor provided in this embodiment includes a motor body 1, a motor housing 5 with a plurality of heat dissipation strip protrusions 2, and a motor rear housing 4 with heat dissipation holes 3. The motor body 1 is located inside the motor housing 5, and a heat dissipation pipe structure component 6 is provided on the outer wall of the motor housing 5, and the heat dissipation pipe structure component 6 is embedded in the plurality of heat dissipation strip protrusions 2. The heat dissipation pipe structure component 6 is used for circulating the coolant. A circulation pump 7 is fixedly installed on the motor rear housing 4, and the circulation pump 7 is connected to the heat dissipation pipe structure component 6. A heat sink 8 is fixedly installed inside the motor rear housing 4, and the heat sink 8 is connected to the heat dissipation pipe structure component 6. The heat pipe structural component 6 is connected to the motor housing 5, and the heat dissipation pipe structural component 6 carries the heat on the motor housing 5 to the heat sink 8 through the circulation pump 7. When the explosion-proof brake motor is in use, the circulation pump 7 is started to drive the coolant to flow in the heat dissipation pipe structural component 6, and when flowing, the heat on the motor housing 5 is transferred to the heat sink 8, and then the heat sink 8 is subjected to heat dissipation treatment to dissipate the heat generated by the motor. In this process, the heat transfer on the motor housing 5 is accelerated by the coolant and the heat dissipation pipe structural component 6, so as to achieve the purpose of quickly cooling the motor housing 5, and then cool the motor host.

[0026] Among them, Figure 1-Figure 7 As shown, the heat dissipation pipe structural component 6 includes a heat absorption pipe 601, an input pipe 602, an output pipe 603 and a heat dissipation pipe 604. There are several heat absorption pipes 601, and one end of the heat absorption pipe 601 is connected to the input pipe 602, and the other end of the heat absorption pipe 601 is connected to the output pipe 603. The input pipe 602 and the output pipe 603 are both connected to the heat dissipation pipe 604. The heat absorption pipe 601, the input pipe 602, the output pipe 603 and the heat dissipation pipe 604 are connected. The coolant enters the heat absorption pipe 601 from the input pipe 602 and then flows out from the output pipe 603. When flowing, the heat on the motor housing 5 is absorbed by the heat dissipation strip protrusion 2, and then the heat is transferred to leave the motor housing 5. When the coolant flows to the heat sink 8, the heat dissipation area of ​​the coolant is expanded through the heat sink 8, so that the heat absorbed in the coolant is quickly released, thereby cooling the coolant.

[0027] Further, such as Figure 1-Figure 7As shown, a plurality of pipe housings 10 are embedded in the heat dissipation strip protrusion 2. The heat dissipation strip protrusion 2 increases the surface area of ​​the motor housing 5, thereby increasing the heat dissipation function of the motor housing 5 to the motor body, so that when the heat of the motor body 1 is transferred to the motor housing 5, the motor housing 5 can quickly dissipate the heat. The heat absorbing pipe 601 is fixedly connected to the pipe housing 10. The pipe housing 10 is used to protect the heat absorbing pipe 601 and transfer heat. The input pipe 602 and the output pipe 603 are fixedly installed The input pipe fitting 602 and the output pipe fitting 603 are respectively located on both sides of the motor housing 5. The input pipe fitting 602 is connected to the circulation pump 7. The circulation pump 7 provides power for the flow of the coolant, so that the coolant flows from the input pipe fitting 602, through the heat absorbing pipe fitting 601, to the output pipe fitting 603. The heat dissipation pipe fitting 604 is fixedly installed in the heat sink 8, and the output end of the heat dissipation pipe fitting 604 is connected to one end of the input pipe fitting 602, and the input end of the heat dissipation pipe fitting 604 is connected to one end of the output pipe fitting 603.

[0028] Furthermore, Figure 1 As shown, a fan body 9 is provided inside the motor rear shell 4, and the heat sink 8 is located between the fan body 9 and the heat dissipation hole 3. The fan body 9 blows the heat on the heat sink 8 to the outside of the motor rear shell 4 through the heat dissipation hole 3. The fan body 9 is connected to the motor body 1. The fan body 9 is a structure on the existing motor. The fan body 9 blows air to the heat sink 8, and then blows the heat on the heat sink 8 out of the heat dissipation hole 3, so as to achieve the purpose of quickly cooling the heat sink 8.

[0029] Further, if Figure 1 As shown, a plurality of fixing blocks 11 are fixedly connected to the motor housing 5, a protective cover 12 is fixedly connected to the fixing blocks 11, and the protective cover 12 is not in contact with the heat dissipation strip protrusion 2, a plurality of ventilation strip holes 13 are opened on the protective cover 12, the protective cover 12 provides protection for the motor housing 5 and the heat dissipation pipe structural assembly 6, and the ventilation strip holes 13 enable the protective cover 12 to have ventilation function while providing protection.

[0030] Further, such as Figure 3 as well as Figure 4 As shown, a plurality of heat dissipation fins 14 are fixedly connected to the bottom of the motor housing 5 , and the heat dissipation fins 14 increase the heat dissipation area of ​​the bottom of the motor housing 5 , thereby increasing the heat dissipation effect of the bottom of the motor housing 5 .

[0031] like Figure 1-Figure 7As shown, the principle of the high-efficiency explosion-proof brake motor provided in this embodiment is as follows: when the explosion-proof brake motor is in use, the circulation pump 7 is started to drive the coolant to flow in the heat dissipation pipe structural component 6. Driven by the circulation pump 7, the coolant flows out from the output pipe fitting 603. When flowing, the heat on the motor housing 5 is absorbed by the heat dissipation long strip protrusion 2, and then the heat is transferred to make the heat leave the motor housing 5. When the coolant flows to the heat sink 8, the heat dissipation area of ​​the coolant is expanded through the heat sink 8. The fan body 9 blows air to the heat sink 8, and then the heat on the heat sink 8 is blown out through the heat dissipation hole 3, so that the heat absorbed in the coolant is quickly released, so as to achieve the purpose of quickly cooling the heat sink 8, thereby cooling the coolant.

[0032] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
