Description

Technical Field

[0001] The utility model relates to the technical field of circulating electric furnace water cooling, in particular to a circulating electric furnace water cooling structure with high efficiency in heat exchange. Background Art

[0002] An electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. Electric furnaces can be divided into resistance furnaces, induction furnaces, arc furnaces, plasma furnaces, electron beam furnaces, etc. Electric furnaces will generate a lot of heat when working. If the heat cannot be dissipated in time, it will cause damage to the equipment. Therefore, water cooling technology is widely used in the manufacture of electric furnaces; the principle of electric furnace water cooling is mainly to use the high thermal conductivity of water. Through the high-speed flow of cooling water, the high-temperature heat generated inside the electric furnace is quickly taken away to achieve an effective cooling effect. However, since the cooling water in the water cooling structure needs to exchange heat quickly to ensure that the entire circulating water cooling structure can effectively provide heat dissipation and cooling for the electric furnace, when the conventional water cooling structure uses a heat recovery device to recycle the heat in the cooling water, although it can effectively recycle and reuse energy, the efficiency of heat exchange and cooling of the cooling water itself is relatively limited, which inevitably affects the efficiency of circulating water cooling to a certain extent. Summary of the invention

[0003] The utility model aims to provide a circulating electric furnace water cooling structure with high efficiency in heat exchange, so as to solve the problems raised in the above-mentioned background technology.

[0004] By making the thermal circulation box and the heat sink frame with the same good thermal conductive material, and setting up three sets of heat sink frames in a zigzag structure inside the thermal circulation box, when the cooling water carrying heat flows to the surface of the heat sink frame, the heat of the cooling water is fully contacted by its structure, so that the heat of the cooling water is quickly and as much as possible absorbed and transferred, and then dissipated into the external environment. The combined use of the spray rack and the heat dissipation fan can atomize the high-temperature cooling water and dissipate its heat quickly. At the same time, the air flow disturbance generated by the heat dissipation fan can be used to quickly cool down the mist-like cooling water.

[0005] By adopting the above technical solution, efficient heat exchange of cooling water inside the water cooling structure is achieved.

[0006] Compared with the prior art, the utility model has the following beneficial effects: the water-cooling structure of the circulating electric furnace with high efficiency heat exchange is provided with three groups of heat dissipation racks in the interior of the heat conduction circulation box, and the three groups of heat dissipation racks are arranged in a zigzag structure with respect to each other, and the guide plates are arranged equidistantly on the surface of the receiving plate, so that a plurality of water flow grooves are formed between them. Therefore, after the cooling water flows through the surface of the entire heat dissipation rack, it will be separated into a plurality of small water flows, and the water flow grooves are fully contacted with the entire heat dissipation rack. Moreover, since the entire heat dissipation rack is made of a material with good heat conduction, the heat dissipation rack is made of a material with good heat conduction. The residual heat in the cooling water will be transferred to the heat sink to the greatest extent, which plays a role in heat exchange and cooling. The several leakage holes opened on the surface of the oblique lower end of each group of receiving plates will make the cooling water between the current receiving plate and the guide plate fall directly to the next group of heat sinks. This process will be repeated three times, so that the residual heat in the cooling water can be transferred away as much as possible in a short time. Finally, the main box made of the same material as the heat sink can be used to dissipate the heat conducted therein to the outside as much as possible, so as to achieve the effect of rapid heat exchange and cooling of the cooling water.

[0007] By setting up a spray rack on the upper part of the main box body, when the high-temperature cooling water transported from the upstream is carried out, it will be finely sprayed under the action of several atomizing nozzles equidistantly arranged on both sides of the shunt pipe. At the same time, the three sets of cooling fans connected and installed at the bottom of the support beam through the adjustment rack and the connecting rack will operate synchronously, and blow the atomized and sprayed cooling water to quickly cool it down. By using the above structure, the temperature of the cooling water can be reduced as much as possible in a short time, and the atomized and blown cooling water will float around, or fall to the surface of the cooling rack, or adhere to the inner wall surface of the main box body to gather into water droplets, and finally flow to the surface of the cooling rack. In this process, the main box body made of good thermal conductive material will assist in absorbing and transferring heat from the cooling water to ensure the high efficiency of heat exchange and cooling of the cooling water.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-5 The utility model provides a technical solution: a circulating electric furnace water cooling structure with high efficiency in heat exchange, comprising a heat conduction circulation box 1 and a heat sink 6, wherein a stable support 2 is symmetrically installed at the bottom of the heat conduction circulation box 1, and a spray frame 3 is horizontally installed at the top of the inner part of the heat conduction circulation box 1, and the left and right sides of the spray frame 3 are connected with a fixing frame 4, and the bottom of the fixing frame 4 is connected with a heat dissipation fan 5, and the heat sink 6 is installed directly below the spray frame 3, and the heat sink 6 comprises a receiving plate 601, a guide plate 602, a baffle 603 and a leakage hole 604, and the top surface of the receiving plate 601 is provided with a guide plate 602, and the front and rear sides of the guide plate 602 are connected with a baffle 603, and the oblique downward end of the receiving plate 601 is provided with a leakage hole 604, and three groups of heat sinks 6 are arranged, and the heat sinks 6 are mutually opposite in a zigzag structure. The heat conduction circulation box 1 includes a main box body 101, a heat dissipation window 102, a first quick connector 103 and a second quick connector 104. The upper ends of the left and right sides of the main box body 101 are provided with heat dissipation windows 102, and the first quick connector 103 is vertically installed in the middle of the top of the main box body 101, and the second quick connector 104 is horizontally installed at the lower end of one side of the main box body 101. By arranging the guide plates 602 equidistantly on the surface of the receiving plate 601, a plurality of guide plates 602 form a water flow trough structure between them. Therefore, after the cooling water flows through the surface of the entire heat dissipation frame 6, it will be separated into a plurality of small water flows, and fully contact the entire heat dissipation frame 6. In addition, since the entire heat dissipation frame 6 is made of a good thermal conductive material, the residual heat in the cooling water will be transferred to the heat dissipation frame 6 to the greatest extent, thereby playing a role in heat exchange and cooling.

[0016] See also Figure 1-5, the structures of the first quick connector 103 and the second quick connector 104 are the same, and both the first quick connector 103 and the second quick connector 104 communicate with the inside of the main box body 101. The spraying rack 3 includes a water delivery pipe 301, a shunt pipe 302, a shunt valve 303 and atomizing nozzles 304. The lower ends of the left and right ends of the water delivery pipe 301 are connected with the shunt pipe 302, and a shunt valve 303 is installed on the surface of the shunt pipe 302. Moreover, one end of the shunt valve 303 away from the shunt pipe 302 is connected with the atomizing nozzle 304. The shunt pipe 302 is arranged in a "囗" - shaped structure, and the water delivery pipe 301 is horizontally arranged above the middle of the shunt pipe 302 and connected with the first quick connector 103. The fixing rack 4 includes a support beam 401, a fixing pipe sleeve 402, an adjusting rack 403 and a connecting rack 404. A plurality of fixing pipe sleeves 402 are arranged at equal intervals on one side of the support beam 401 close to the spraying rack 3, and an adjusting rack 403 is arranged at the bottom of the support beam 401. Moreover, the bottom of the adjusting rack 403 is connected with the connecting rack 404. The shunt pipe 302 horizontally penetrates through the middle of the inside of the fixing pipe sleeve 402. The bottom of the connecting rack 404 is fixedly connected with the top of the cooling fan 5. When the high - temperature cooling water is transported from upstream, under the action of a plurality of atomizing nozzles 304 arranged at equal intervals on both sides of the shunt pipe 302, it will be atomized and sprayed out. At the same time, three groups of cooling fans 5 connected and installed at the bottom of the support beam 401 through the adjusting rack 403 and the connecting rack 404 will operate synchronously, blow the atomized and sprayed cooling water, and quickly cool it down.

[0017] In summary, please refer to Figure 1-5 , first, with the assistance of the first quick connector 103, the used cooling water from upstream will enter the spraying rack 3 through the pipeline. Under the transportation of the water delivery pipe 301 and the shunt pipe 302, it will enter a plurality of shunt valves 303 arranged at equal intervals on both sides of the shunt pipe 302. Under the transportation of the shunt valve 303, it will enter the inside of the atomizing nozzle 304. By using the operation of the atomizing nozzle 304, the cooling water carrying high heat will be atomized and sprayed out;

[0018] At this time, the cooling fans 5 installed at the bottom of the support beam 401 by using the adjusting rack 403 and the connecting rack 404 start to operate synchronously, blow the atomized and sprayed cooling water on the left and right sides respectively. At this time, since a hydrophobic breathable film is installed on the surface of the heat dissipation window 102, the water vapor will not disperse to the outside of the entire heat conduction circulation box 1. With the cooperation of the spraying rack 3 and the cooling fans 5 at the bottom of the fixing rack 4, rapid heat exchange is carried out for the cooling water;

[0019] Then, the atomized cooling water will gradually fall onto the surface of the heat sink 6. As the cooling water contacts the receiving plate 601, the guide plate 602, and the baffle 603, since the entire heat sink 6 is made of a good thermal conductive material, the residual heat in the cooling water will be transferred to the heat sink 6 as much as possible, and dissipated to the outside world through the main box 101 made of the same material as the heat sink 6.

[0020] As the water mist on the surface of the heat sink 6 gathers and forms a water flow, the cooling water will flow along the surface of the receiving plate 601 and the guide plate 602 to the leakage hole 604, and fall vertically to the surface of the next group of heat sinks 6 for another heat exchange and cooling. This process is repeated three times, and finally converges on the inner bottom side of the receiving plate 601, and finally is output by the downstream equipment with the assistance of the second quick connector 104, and is re-delivered to the electric furnace for another round of water cooling treatment.
