Abstract
Description
Technical Field
[0001] The present application relates to the technical field of radiators, and in particular to a radiator for a mine explosion-proof cabinet. Background Art
[0002] When mining, there are flammable and explosive gases such as methane in the mine. Once these gases leak and encounter sparks or high temperatures, explosions will occur. In order to ensure the safety of miners and equipment, some controllers and other equipment that generate more heat are usually equipped with explosion-proof and flameproof radiators to prevent fire and explosion incidents and protect the lives and property of miners.
[0003] At present, the heat sinks of general-purpose controller products are mostly made of aluminum, but due to explosion-proof requirements, aluminum materials cannot be used in underground coal mine products. Usually, the radiators used in mines are usually made of copper, especially red copper, which has excellent thermal conductivity and corrosion resistance. Most underground coal mining machine intermediate boxes, scraper conveyor main controls and belt conveyor main controls use pure copper radiators.
[0004] However, as a radiator mainly used for explosion-proof purposes in mines, the equipment protected by the radiator may explode in the unpredictable environment of the mine, and a material that can withstand high pressure, impact and vibration is required. Therefore, copper may not provide sufficient strength to meet the explosion-proof requirements. In addition, the cost of copper is high, and the price of pure copper radiators is relatively high. Utility Model Content
[0005] In order to address the deficiencies in the prior art, the present application provides a radiator for a mine explosion-proof cabinet, which can have good heat dissipation and high hardness to withstand the impact force caused by the explosion.
[0006] The present application provides a mine explosion-proof cabinet radiator adopting the following technical solution:
[0007] A mine explosion-proof cabinet radiator comprises a steel shell, wherein the top surface of the steel shell is provided with an embedding groove, a copper heat sink is embedded in the steel shell in the embedding groove, and the joint between the steel shell and the copper heat sink forms an explosion-proof joint surface.
[0008] By adopting the above technical scheme, the copper heat sink has good thermal conductivity, so that the equipment operating in the mine can dissipate heat efficiently when protected by the steel shell. At the same time, the steel shell surrounding the copper heat sink has high strength and hardness. The explosion-proof joint surface formed by the joint surface of the copper heat sink and the steel shell can withstand the high pressure and impact in the mine environment, and can save the amount of copper and save costs.
[0009] The present application further provides that: a sealing strip is provided at the bottom of the copper heat sink, and the sealing strip is embedded in the bottom wall of the embedding groove in the steel shell.
[0010] By adopting the above technical solution, the sealing strip can strengthen the sealing of the joint between the steel shell and the copper heat sink, making the connection between the steel shell and the copper heat sink tighter, thereby enhancing the overall waterproofness.
[0011] The present application further configures: a first screw hole is opened on the top surface of the copper heat sink, a second screw hole is opened on the bottom wall of the steel shell located in the embedded groove, the copper heat sink is threadedly connected with a screw rod in the first screw hole, and the rod end of the screw rod is threadedly connected in the second screw hole.
[0012] By adopting the above technical solution, while the screw is fastening the copper heat sink and the steel shell, since the rod head of the screw is located on the top surface of the copper heat sink, that is, one side of the copper heat sink on the steel shell is exposed, and the exposed side of the copper heat sink faces the protected object, and the rod end is located inside the steel shell, when the side of the steel shell away from the copper heat sink contacts water, water will not enter the explosion-proof joint surface along the screw and the copper heat sink.
[0013] The present application further provides that: a waterproof ring is sleeved on the bottom of the rod head of the screw rod, and the bottom of the waterproof ring abuts against the groove wall of the embedding groove located at the top of the second screw hole.
[0014] By adopting the above technical solution, the waterproof ring can block part of the water located near the explosion-proof joint from entering the copper heat sink, thereby minimizing the impact of water on the explosion-proof effect of the steel shell at the copper heat sink.
[0015] The present application further provides that: the top surface of the copper heat sink is raised above the top surface of the steel shell.
[0016] By adopting the above technical solution, the heat dissipation area of the copper heat sink can be increased, and the heat diffused from the copper heat sink to the steel shell can be reduced, thereby enhancing the heat dissipation performance of the steel shell.
[0017] The present application further arranges: a water channel group is opened in the steel shell and / or the copper heat sink, and a water outlet and a water inlet are arranged on the bottom surface of the steel shell and / or the copper heat sink, the water inlet is connected to one end of the water channel group, and the water outlet is connected to the other end of the water channel group.
[0018] By adopting the above technical solution, the water inlet and the water outlet are arranged on the bottom surface of the steel shell, that is, they are arranged on the opposite surface of the steel shell where the copper heat sink is exposed, which does not affect the explosion-proof performance. In addition, the coolant is injected into the water inlet and enters the water channel group. The coolant flows through the water channel group and is discharged from the water outlet. The flow of the coolant in the water channel group of the steel shell and / or the copper heat sink can take away part of the heat, so that the heat dissipation efficiency of the steel shell and / or the copper heat sink is higher.
[0019] The present application further provides that: a plurality of the copper heat sinks are provided, the plurality of the copper heat sinks are embedded in the embedding grooves of the steel shell, and a plurality of the water channel groups are provided.
[0020] By adopting the above technical solution, multiple copper heat sinks and multiple water channel groups can improve the heat dissipation effect of the side of the steel shell facing the protected object.
[0021] The present application further provides that: a first connecting groove is opened between adjacent water channel groups in the steel shell and / or the copper heat sink, and the first connecting groove is connected to both ends of the adjacent water channel groups in the steel shell and / or the copper heat sink.
[0022] By adopting the above technical solution, the first connecting groove connects all the water channel groups in series. The series-connected water channel groups can enable the coolant to flow evenly in the water channel groups of the steel shell and / or the copper heat sink, thereby making the heat dissipation effect of the steel shell and / or the copper heat sink more stable.
[0023] The present application further arranges: a second connecting groove and a third connecting groove are opened between adjacent water channel groups in the steel shell and / or the copper heat sink, the second connecting groove is connected to one end of the adjacent water channel group close to the water inlet and the water outlet, and the third connecting groove is connected to one end of the adjacent water channel group away from the water inlet and the water outlet.
[0024] By adopting the above technical solution, the second connecting groove and the third connecting groove connect all the water channel groups in parallel, and the coolant can pass through the water channel groups in the second connecting groove and the third connecting groove at the same time. The parallel water channel groups are discharged from the water inlet to the water outlet more quickly, thereby increasing the flow rate of the coolant and increasing the heat absorption and dissipation capacity of the steel shell and / or the copper heat sink, thereby improving the heat dissipation efficiency.
[0025] In summary, this application has the following beneficial effects:
[0026] The copper heat sink in the present application can achieve good heat dissipation, and the steel shell outside the copper heat sink can protect the copper heat sink, thereby improving the overall strength and hardness, so that the equipment operating in the mine can dissipate heat efficiently when protected by the steel shell, and the joint surface between the copper heat sink and the steel shell forms an explosion-proof joint surface, which can withstand high pressure and impact in the mine environment, and at the same time can save the amount of copper, thereby saving the cost of production.

DETAILED DESCRIPTION
[0034] The following is combined with Figures 1 to 6 This application is described in further detail.
[0035] Embodiment 1:
[0036] refer to Figures 1 to 3 In this embodiment, a mine explosion-proof cabinet radiator includes a steel shell 1, and an embedding groove 101 is provided on the top surface of the steel shell 1. A copper heat sink 2 is fixedly embedded in the steel shell 1 in the embedding groove 101. Copper has good thermal conductivity. The high thermal conductivity can effectively transfer heat from the radiator to the surrounding environment, providing an efficient heat dissipation effect. The copper heat sink 2 has excellent corrosion resistance, and can reduce the risk of overall corrosion damage in mines with corrosive gases, liquids, etc. The strength and hardness of copper are relatively low compared to steel. The steel shell 1 surrounds the copper heat sink 2, and the joint of the steel shell 1 and the copper heat sink 2 forms an explosion-proof joint surface 100, which enhances the overall strength and hardness, and can withstand high pressure and impact in the mine environment. In addition, the cost of copper is relatively high, and the low-cost steel as the main component can save the amount of copper and save production costs.
[0037] Furthermore, a sealing strip 10 is fixedly connected to the bottom of the copper heat sink 2, and the sealing strip 10 is embedded in the bottom wall of the embedding groove 101 in the steel shell 1. In the present embodiment, the sealing strip 10 is selected as a rubber ring, which is elastic and can enhance the connection strength between the steel shell 1 and the copper heat sink 2, reduce the width of the connection seam between the steel shell 1 and the copper heat sink 2, and thus improve the waterproofness of the connection between the steel shell 1 and the copper heat sink 2.
[0038] Furthermore, a first screw hole 102 is provided on the top surface of the copper heat sink 2, and a second screw hole 103 is provided on the bottom wall of the steel shell 1 located in the embedding groove 101. The copper heat sink 2 is located in the first screw hole 102 and is threadedly connected with a screw 6, and the rod end of the screw 6 is threadedly connected to the second screw hole 103, that is, the screw 6 fixes the steel shell 1 and the copper heat sink 2 together, and the top surface of the steel shell 1, that is, the exposed surface of the copper heat sink 2 on the steel shell 1, faces the protected object, while the bottom surface of the steel shell 1, that is, the opposite side of the exposed surface of the copper heat sink 2 on the steel shell 1, is easily exposed to water during underground mining operations, and the rod head of the screw 6 is located on the top surface of the steel shell 1, and the rod end is located inside the steel shell 1, so the screw 6 is difficult to contact with water, and then it is difficult for water to enter the steel shell 1 and / or the copper heat sink 2 from the screw 6, thereby improving the waterproofness of the steel shell 1 and / or the copper heat sink 2.
[0039] In addition, a waterproof ring 11 is sleeved at the bottom of the rod head of the screw rod 6, and the bottom of the waterproof ring 11 abuts against the groove wall of the embedded groove 101 located at the top of the second screw hole 103. In the present embodiment, the waterproof ring 11 is selected as a rubber ring to block part of the water located on the top surface of the steel shell 1 from entering the interior of the copper heat sink 2, thereby reducing the water from entering the explosion-proof joint surface 100 of the steel shell 1 located at the copper heat sink 2, thereby reducing the impact on the explosion-proof effect.
[0040] Preferably, in this embodiment, the surface roughness of the steel shell 1 and the copper heat sink 2 is 6.3 μm, and the width of the joint surface between the steel shell 1 and the copper heat sink 2 is 12.5 mm, so as to meet the first-class explosion-proof standard.
[0041] Furthermore, the top surface of the copper heat sink 2 is raised above the top surface of the steel shell 1. The raised copper heat sink 2 increases the heat dissipation area of the surface, thereby being able to dissipate heat in multiple directions, and avoiding the copper heat sink 2 from diffusing heat to the top surface of the steel shell 1 as much as possible, thereby improving the heat dissipation efficiency of the steel shell 1.
[0042] Furthermore, a water channel group 3 is opened in the steel shell 1 and / or the copper heat sink 2, and a plurality of water channel groups 3 are arranged, and the plurality of water channel groups 3 are interconnected. A water outlet 5 and a water inlet 4 are fixedly connected to the bottom surface of the steel shell 1 and / or the copper heat sink 2. The water inlet 4 is connected to one end of the water channel group 3, and the water outlet 5 is connected to the other end of the water channel group 3. The coolant can enter the water channel group 3 from the water inlet 4, and the coolant absorbs the heat of the steel shell 1 and / or the copper heat sink 2 through the inner wall of the water channel group 3. The coolant carrying the heat is discharged from the water outlet 5, thereby further improving the heat dissipation efficiency of the steel shell 1 and / or the copper heat sink 2.
[0043] In addition, multiple copper heat sinks 2 are provided, and multiple copper heat sinks 2 are embedded in the embedding groove 101 of the steel shell 1. Multiple water channel groups 3 are provided, which can enhance the heat dissipation effect of the steel shell 1 and / or the copper heat sink 2. In this embodiment, three copper heat sinks 2 are provided, and the water channel group 3 is located inside the copper heat sink 2, thereby improving the heat dissipation performance of the copper heat sink 2.
[0044] refer to Figure 4 and Figure 5 In this embodiment, a first connecting groove 7 is provided between adjacent water channel groups 3 in the steel shell 1 and / or the copper radiating plate 2. The first connecting groove 7 is connected to both ends of the adjacent water channel groups 3 in the steel shell 1 and / or the copper radiating plate 2. The first connecting groove 7 connects all the water channel groups 3 in series. Therefore, when the coolant enters from the water inlet 4 through the water channel groups 3 in the steel shell 1 and / or the copper radiating plate 2 and is discharged from the water outlet 5, it can flow evenly in the water channel group 3, thereby making the heat dissipation effect of the steel shell 1 and / or the copper radiating plate 2 more stable.
[0045] The implementation principle of the embodiment of the present application is as follows: the steel shell 1 provides higher strength and hardness for the outer edge of the copper heat sink 2, most of the heat of the protected equipment is dissipated from the copper heat sink 2, and part is dissipated from the steel shell 1, and the coolant enters from the water inlet 4 through the water channel group 3 and the first connecting groove 7, and is then discharged from the water outlet 5, thereby achieving heat dissipation of the steel shell 1 and / or the copper heat sink 2.
[0046] Embodiment 2:
[0047] refer to Figure 6 , the difference between this embodiment and embodiment 1 lies in the connection mode of the water channel group 3. In this embodiment, a second connecting groove 8 and a third connecting groove 9 are provided between adjacent water channel groups 3 in the steel shell 1 and / or the copper heat sink 2. The second connecting groove 8 is connected to one end of the adjacent water channel group 3 close to the water inlet 4 and the water outlet 5, and the third connecting groove 9 is connected to one end of the adjacent water channel group 3 away from the water inlet 4 and the water outlet 5. The second connecting groove 8 and the third connecting groove 9 connect all the water channel groups 3 in parallel, and the coolant flows in the water channel group 3 and the second connecting groove 8 and the third connecting groove 9. The shortest distance of the coolant from the water inlet 4 to the water outlet 5 is short. Therefore, the flow rate of the coolant entering and leaving the steel shell 1 and / or the copper heat sink 2 per unit time is increased, and the renewal speed of the coolant is fast, thereby increasing the heat absorption and dissipation capacity of the steel shell 1 and / or the copper heat sink 2.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
