Description

Technical Field

[0001] The invention relates to the technical field of mechanical heat dissipation, and in particular to a heat dissipation component and a radiator for oilfield machinery. Background Art

[0002] Radiator is a common heat transfer device, which generally transfers the heat generated inside the machine by circulating the refrigerant in the radiator, so as to achieve the cooling inside the machine. A large amount of heat will be generated during the operation of the mechanical equipment, so the radiator is an indispensable device for the normal operation of the mechanical equipment. For example, the existing public document CN105889104A - A radiator for petroleum machinery and equipment and the existing public document CN216282887U - A plate-fin radiator for engineering machinery, both disclose a radiator for heat dissipation of mechanical equipment. Although the above radiators can meet the heat dissipation requirements of mechanical equipment during normal operation, the existing radiators still have the following deficiencies in actual use: 1. Existing radiators are all fixed in structure when in use, which results in limited efficiency of heat conduction in actual use. In actual use, in order to improve the heat dissipation efficiency, it is necessary to increase the heat exchange rate by increasing the circulation efficiency of the refrigerant, which not only reduces the service life of the equipment but also increases energy consumption, resulting in poor overall practicality; 2. Because the working environment of oilfield machinery contains a lot of dust and oil gas when it is working, a lot of oily dirt will adhere to the inside of the radiator during long-term use. The adhesion of dirt will indirectly reduce the heat conduction efficiency, thereby reducing the heat dissipation effect; Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the problem that the above-mentioned existing heat dissipation components have energy waste when adjusting the heat exchange efficiency in actual use, a heat dissipation component for oilfield machinery is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a heat dissipation component for oilfield machinery, comprising: a heat dissipation part, comprising a fixed heat conducting plate and a dynamic heat conducting plate which is slidably inserted into the fixed heat conducting plate from the upper end of the fixed heat conducting plate, a plurality of fixed heat conducting plates are arranged in an array in a horizontal direction to form a group of fixed heat conducting plates, a plurality of groups of solid heat conducting plates are arranged in an array in a horizontal direction, the lower ends of a plurality of fixed heat conducting plates in the same group are connected through a fixed first connecting plate, and the side walls of two adjacent first connecting plates are connected through a fixed first transition plate, the upper ends of a plurality of dynamic heat conducting plates in the same group are connected through a fixed second connecting plate, and the side walls of two adjacent second connecting plates are connected through a fixed second transition plate, the plurality of first connecting plates and the plurality of second connecting plates are arranged in a one-to-one correspondence, an end plate is fitted at the lower end of the dynamic heat conducting plate, and a blocking column with a semicircular free end is fixed on the top surface of the end plate along the long side direction, An air intake groove for matching the gap of the blocking column is provided on the bottom surface of the dynamic heat conducting plate on both sides of the air intake groove, and magnetic plates are symmetrically embedded and fixed on the bottom surfaces of the dynamic heat conducting plates on both sides of the air intake groove, and guide blocks are symmetrically fixed on the two end surfaces of the end plates, and guide rail grooves for matching the gap of the guide blocks are provided in the vertical direction on the inner walls of the fixed heat conducting plates, and the number of fixed heat conducting plates in the same group is an odd number, and the length of the guide rail grooves is gradually reduced from the middle fixed heat conducting plate to the fixed heat conducting plates on both sides; and a matching part includes an upper fixed plate fixed above the heat dissipation element and a lower fixed plate fixed below the heat dissipation element, an L-shaped frame is fixedly provided on the bottom surface of one side of the upper fixed plate extending downward, a first screw rod is spirally sleeved on the horizontal plate of the L-shaped frame, and the lower end of the first screw rod is embedded in the output end of the first motor, the first screw rod is rotatably sleeved on the lower fixed plate through a rolling bearing, and the first motor is fixedly connected to the bottom surface of the lower fixed plate.

[0006] The beneficial effects of the present invention are as follows: when the radiator is in use, the first screw rod can be rotated by the operation of the first motor, and because of the spiral fit between the first screw rod and the L-shaped frame, the position of the movable heat conducting plate relative to the fixed heat conducting plate can be adjusted in the vertical direction under the operation of the first motor, so that the contact area between the movable heat conducting plate and the fixed heat conducting plate and the air can be increased, thereby increasing the surface area to improve the heat exchange efficiency; In addition, when the position of the moving heat transfer plate is adjusted relative to the fixed heat transfer plate, guide rail grooves of different lengths are set. When the moving heat transfer plate drives the end plate to move, after the guide block on one side of the end plate moves to the end of the guide rail groove, the moving heat transfer plate continues to move while the end plate is limited by the obstruction of the end of the guide rail groove, thereby realizing the opening of the air inlet groove at one end of the moving heat transfer plate to realize the circulation of refrigerant therein. In the case of different guide rail groove lengths, as the moving heat transfer plate is extended, the number of moving heat transfer plates through which the refrigerant circulates can be adjusted. In this way, the heat exchange is further improved by increasing the amount of refrigerant circulating per unit time. This heat exchange method is simple to operate and has high heat exchange efficiency, good overall practicality, and effectively reduces energy waste.

[0011] As a preferred solution of a heat dissipation component for oilfield machinery of the present invention, it also includes a fixed guide plate, a plurality of fixed guide plates are arranged in an array along the horizontal direction to form a group of fixed guide plates, a plurality of groups of solid guide plates are arranged in an array along the horizontal direction, a plurality of groups of solid guide plates and a plurality of groups of solid heat conducting plates are arranged alternately, and a plurality of fixed guide plates in the same group are staggered on one side of a plurality of fixed heat conducting plates in the same group; a dynamic guide plate is slidably sleeved in the solid guide plate, a plurality of fixed guide plates in the same group are fixed at their lower ends on the same connecting plate, a plurality of dynamic guide plates in the same group are fixed at their upper ends on another same connecting plate, connecting columns are symmetrically fixed at both ends of one side of the connecting plate, and the other end of the connecting column is fixed on the upper fixed plate and / or the lower fixed plate.

[0012] In view of the problem that the existing radiator cannot self-clean the internal dust when in use, thus reducing the heat exchange efficiency, a radiator for oilfield machinery is proposed, including a heat dissipation component for oilfield machinery; and a dust removal part, the dust removal part includes a chain, a rotating rod, a scraper frame and a second screw rod, the scraper frame is gap-fitted inside the moving heat conducting plate, and the second screw rod is arranged on the inner side of the scraper frame along the long side direction of the moving heat conducting plate, a second shovel frame is fixedly provided on the lower side wall of the scraper frame, and a threaded sleeve for spirally fitting with the second screw rod is fixedly provided on the inner wall of the scraper frame; a second conical tooth is fixedly provided on the upper end of the second screw rod, and the second screw rod is fixedly provided with a second conical tooth.

[0013] Another beneficial effect of the present invention is that when the radiator is in use, the transmission of each gear plate is realized through the chain. When the second motor is working, multiple rotating rods can be rotated synchronously. Because the first conical teeth and the second conical teeth on the rotating rod are meshed, multiple second screw rods can be rotated synchronously. Finally, the spiral matching setting between the second screw rod and the threaded sleeve, when the second screw rod rotates, will drive the second shovel frame to move up and down in the dynamic heat conduction plate, so as to scrape off the dirt on the inner wall of the dynamic heat conduction plate. When adjusting the heat exchange efficiency, when the dynamic heat conduction plate is moved relative to the solid heat conduction plate, the first shovel frame will scrape off the dirt on the inside of the solid heat conduction plate. Through the above-mentioned setting, the dirt inside the dynamic heat conduction plate and the solid heat conduction plate can be effectively scraped off, the heat exchange efficiency can be maintained, and the overall practicality can be improved.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0033] Reference Figure 1 , Figure 2 and Figure 3 , which is the first embodiment of the present invention, provides a heat dissipation assembly for oilfield machinery. The heat dissipation assembly is arranged inside the oilfield machinery. The heat dissipation element 100 is used for heat exchange, and the matching element 200 can adjust the shape of the heat dissipation element 100.

[0034] Specifically, it includes a heat sink 100, including a fixed heat conductive plate 101 and a movable heat conductive plate 102 that is slidably inserted into the fixed heat conductive plate 101 from the upper end of the fixed heat conductive plate 101; and a matching component 200, including an upper fixed plate 201 fixed above the heat sink 100 and a lower fixed plate 202 fixed below the heat sink 100.

[0035] See Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a plurality of fixed heat conducting plates 101 are arranged in an array in a horizontal direction to form a group of fixed heat conducting plates 101. The plurality of groups of fixed heat conducting plates 101 are arranged in an array in a horizontal direction. The lower ends of the plurality of fixed heat conducting plates 101 in the same group are connected through a fixed first connecting plate 101b, and the side walls of two adjacent first connecting plates 101b are connected through a fixed first transition plate 101b-1, so that the connection between the plurality of groups of fixed heat conducting plates 101 can be achieved. The upper ends of the plurality of dynamic heat conducting plates 102 in the same group are connected through a fixed second connecting plate 102b, and the side walls of two adjacent second connecting plates 102b are connected through a fixed second transition plate 102b-1, so that the connection between the plurality of groups of dynamic heat conducting plates 102 can be achieved. The plurality of first connecting plates 101b and the plurality of second connecting plates 102b are arranged in a one-to-one correspondence. An air inlet box 101c is fixedly provided on the first connecting plate 101b below one side of the heat sink 100, and an air outlet box 102c is fixedly provided on the second connecting plate 102b above the other side of the heat sink 100. An air inlet pipe 101c-1 is fixedly provided on the top surface of the air inlet box 101c to allow the refrigerant to enter, and an air outlet pipe 102c-1 is fixedly provided on the top surface of the air outlet box 102c to allow the refrigerant to be discharged; When the above arrangement is in use, the refrigerant enters the air inlet box 101c through the air inlet pipe 101c-1. After entering, the refrigerant can flow through each solid heat conductive plate 101 through the cooperation of the first connecting plate 101b and the first transition plate 101b-1. The refrigerant in the solid heat conductive plate 101 then enters each dynamic heat conductive plate 102, and is finally discharged from the air outlet pipe 102c-1 on the air outlet box 102c under the action of the second connecting plate 102b and the second transition plate 102b-1. In this way, heat exchange with the outside of the solid heat conductive plate 101 and the dynamic heat conductive plate 102 can be achieved.

[0036] In actual use, the refrigerant includes cold air sucked from the outside by an air intake fan or gas compressed by a compressor (including physical cooling); in addition, in actual use, the device also includes a controller (not shown in the drawings) for controlling various electrical components.

[0037] Furthermore, a first sealing frame 101a is fixedly provided on the inner wall of the upper end of the fixed heat conducting plate 101, and a first sealing groove 101a-1 for interference fit of the first sealing ring 101a-2 is opened on the inner wall of the first sealing frame 101a, thereby achieving a seal between the fixed heat conducting plate 101 and the movable heat conducting plate 102; a second sealing frame 102a is fixedly provided on the outer wall of the lower end of the movable heat conducting plate 102, and a second sealing groove 102a-1 for interference fit of the second sealing ring 102a-2 is opened on the outer wall of the second sealing frame 102a, thereby achieving a seal between the fixed heat conducting plate 101 and the movable heat conducting plate 102.

[0038] See Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, the lower end of the dynamic heat conducting plate 102 is fitted with an end plate 102d, and a blocking column 102d-1 with a semicircular free end is fixedly arranged on the top surface of the end plate 102d along the long side direction, and an air inlet groove 102e for gap fitting of the blocking column 102d-1 is opened on the bottom surface of the dynamic heat conducting plate 102, so that the air circulation of the air inlet groove 102e can be controlled. Magnetic plates 102f are symmetrically embedded and fixed on the bottom surface of the dynamic heat conducting plate 102 on both sides of the air inlet groove 102e, and the magnetic plates 102f are opposite to the end plates. 102d is magnetically adsorbed to achieve the firmness of the fit between the end plate 102d and the dynamic heat conducting plate 102. Guide blocks 102d-2 are symmetrically fixed on both end surfaces of the end plate 102d, and a guide rail groove 101d for the clearance fit of the guide block 102d-2 is opened in the vertical direction on the inner wall of the fixed heat conducting plate 101. The number of the fixed heat conducting plates 101 in the same group is an odd number, and the length of the guide rail groove 101d is gradually reduced from the middle fixed heat conducting plate 101 to the fixed heat conducting plates 101 on both sides. When the above arrangement is in use, when the blocking column 102d-1 is engaged on the air inlet groove 102e, the dynamic heat conductive plate 102 is in a closed state, and the refrigerant entering through the solid heat conductive plate 101 cannot be conducted out from the dynamic heat conductive plate 102; when the dynamic heat conductive plate 102 moves relative to the solid heat conductive plate 101, it will drive the end plate 102d to move synchronously; through the setting of the guide block 102d-2, when the guide block 102d-2 moves to the end of the guide rail groove 101d, the guide block 102d-2 is limited, and the end plate 102d is separated from the dynamic heat conductive plate 102; in this way, the refrigerant can enter the dynamic heat conductive plate 102 through the air inlet groove 102e; the guide rail groove 101d is set with different lengths, and the number of dynamic heat conductive plates 102 used for refrigerant conduction can be adjusted as the dynamic heat conductive plate 102 moves.

[0039] See Figure 1 , Figure 5 , Figure 6 and Fig.13 As shown, an L-shaped frame 201b is fixedly provided on the bottom surface of one side of the upper fixing plate 201 extending downward, a first screw rod 203 is spirally sleeved on the horizontal plate of the L-shaped frame 201b, and the lower end of the first screw rod 203 is embedded in the output end of the first motor 203a, the first screw rod 203 is rotatably sleeved on the lower fixing plate 202 through a rolling bearing, and the first motor 203a is fixedly connected to the bottom surface of the lower fixing plate 202; Relative to the other end of the lower fixed plate 202 provided with the first screw rod 203, fixed columns 202a are symmetrically fixed on both sides of the top surface, and a movable column 201a is slidably sleeved in the fixed column 202a, and the upper end of the movable column 201a is fixed on the bottom surface of the upper fixed plate 201. This arrangement can play a role in limiting and guiding the movement of the upper fixed plate 201; When the above arrangement is in use, the first motor 203a can be used to rotate the first screw rod 203. Due to the spiral matching arrangement between the first screw rod 203 and the L-shaped frame 201b, the L-shaped frame 201b can drive the upper fixed plate 201 to move in the vertical direction relative to the lower fixed plate 202 under the rotation of the first screw rod 203, thereby realizing the movement of the movable heat conducting plate 102 in the vertical direction relative to the fixed heat conducting plate 101.

[0040] Furthermore, first L-shaped plates 101b-2 for inserting the lower fixed plate 202 are symmetrically fixed on both sides of the bottom surface of the first connecting plate 101b, and the first L-shaped plate 101b-2 and the lower fixed plate 202 are fixed by bolts, and second L-shaped plates 102b-2 for inserting the upper fixed plate 201 are symmetrically fixed on both sides of the top surface of the second connecting plate 102b, and the second L-shaped plate 102b-2 and the upper fixed plate 201 are fixed by bolts, so that the detachable cooperation between the upper fixed plate 201 and the movable heat conducting plate 102, and the detachable cooperation between the lower fixed plate 202 and the fixed heat conducting plate 101 can be achieved. Example 2

[0041] Reference Figure 4 and Fig.13 , which is the second embodiment of the present invention, is based on the previous embodiment, except that, in order to improve the effect of heat exchange, the air is guided to a certain extent.

[0042] Specifically, it also includes a solid guide plate 204, and multiple solid guide plates 204 are arranged in an array along the horizontal direction to form a group of solid guide plates 204. Multiple groups of solid guide plates 204 are arranged in an array along the horizontal direction. Multiple groups of solid guide plates 204 and multiple groups of solid heat conducting plates 101 are arranged alternately, and multiple solid guide plates 204 in the same group are staggered on one side of multiple solid heat conducting plates 101 in the same group. When this arrangement is in use, the air inside the machine is driven by the fan to circulate to the heat sink 100, and the arrangement of the solid guide plates 204 can divert the guided air to both sides, so as to achieve full contact between the hot air and the heat sink 100, thereby improving the heat exchange efficiency.

[0043] Furthermore, a dynamic guide plate 204a is slidably sleeved in the fixed guide plate 204, and the lower ends of multiple fixed guide plates 204 in the same group are fixed on the same connecting plate 204b, and the upper ends of multiple dynamic guide plates 204a in the same group are fixed on another same connecting plate 204b. Connecting columns 204b-1 are symmetrically fixed at both ends of one side of the connecting plate 204b, and the other end of the connecting column 204b-1 is fixed on the upper fixed plate 201 and / or the lower fixed plate 202. When this arrangement is in use, when the dynamic heat conducting plate 102 moves in the vertical direction relative to the fixed heat conducting plate 101, the dynamic guide plate 204a will move synchronously relative to the fixed guide plate 204, so that sufficient guide air can be achieved. Example 3

[0044] Reference Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.10 , which is the third embodiment of the present invention, provides a radiator for oilfield machinery, including the heat dissipation component and dust removal component 300 in any of the above embodiments.

[0045] Specifically, the dust removal member 300 includes a chain 301, a rotating rod 302, a scraper frame 303 and a second screw rod 304. The scraper frame 303 is loosely fitted inside the dynamic heat conducting plate 102. The second screw rod 304 is arranged on the inner side of the scraper frame 303 along the long side direction of the dynamic heat conducting plate 102. A second shovel frame 303a is fixedly provided on the lower side wall of the scraper frame 303. At the same time, a threaded sleeve 303b for spirally fitting with the second screw rod 304 is fixedly provided on the inner wall of the scraper frame 303. The upper end of the second screw rod 304 is fixedly provided with a second conical tooth 304a, and the lower end of the second screw rod 304 is slidably sleeved with a fixing frame 304b, and the fixing frame 304b is fixedly connected to the inner wall of the dynamic heat conducting plate 102 by screws, and a rotating rod 302 is provided in the second connecting plate 102b, and a plurality of first conical teeth 302b are fixedly provided on the rotating rod 302, respectively meshing with a plurality of second conical teeth 304a in the same group of dynamic heat conducting plates 102, one end of the rotating rod 302 slides through the through hole and extends to the outside of the second connecting plate 102b and is fixedly connected to the gear plate 302a, and the plurality of gear plates 302a are driven by the same chain 301, one end of one of the rotating rods 302 also passes through the gear plate 302a and is embedded in the output end of the second motor 302c, and the second motor 302c is fixedly provided on the outer wall of the second connecting plate 102b; A first shovel frame 102a-3 is fixed on the bottom surface of the second sealing frame 102a and is in contact with the inner wall of the fixed heat conducting plate 101; The other end of the rotating rod 302 is slidably sleeved in the positioning sleeve 102b-3, and the positioning sleeve 102b-3 is fixed on the inner wall of the second connecting plate 102b. The positioning sleeve 102b-3 can limit one end of the rotating rod 302. The cross-section of the through hole is convex, and the large diameter end of the through hole is arranged on the side close to the inside of the second connecting plate 102b. A rubber ring is arranged in the large diameter end of the through hole. This arrangement can improve the sealing performance between the rotating rod 302 and the second connecting plate 102b. When the above arrangement is in use, the rotation of one of the rotating rods 302 can be realized through the operation of the second motor 302c, and because the gear plate 302a on the rotating rod 302 is driven by the chain 301, the synchronous rotation of multiple rotating rods 302 can be realized. Because the first conical tooth 302b and the second conical tooth 304a are engaged, the synchronous rotation of multiple second screw rods 304 is finally realized. Due to the spiral matching arrangement between the second screw rod 304 and the threaded sleeve 303b, the scraper frame 303 will move along the axial direction of the second screw rod 304, thereby realizing the second shovel frame 303a on the scraper frame 303 to scrape the dirt inside the movable heat conducting plate 102. At the same time, the movement of the movable heat conducting plate 102 relative to the solid heat conducting plate 101 can realize the scraping of the dirt inside the solid heat conducting plate 101 by the first shovel frame 102a-3.

[0046] Furthermore, the free end of the air inlet box 101c is open, and the free end of the air outlet box 102c is closed. The free end of the air inlet box 101c is slidably sleeved with an end box 101c-2. A first flange frame 101c-3 is fixedly provided on the outer side wall of the upper end of the end box 101c-2. A second flange frame 101c-4 is fixedly provided on the outer side wall of the air inlet box 101c.
