Description

Technical Field

[0001] The invention relates to the technical field of pipe connection, in particular to a fin pipe connector of a plate-type radiator. Background Art

[0002] The plate radiator is composed of several radiators connected by pipes, and a cavity is provided inside the radiator for fluid heat dissipation. The old-fashioned plate radiator connects several radiators together by welding. This method is simple and effective and is widely used. However, the plate radiator may be damaged during use. The radiator connected by welding is not convenient to disassemble and repair. The only way is to replace the entire plate radiator, which has a high maintenance cost. The existing solution changes the traditional welding connection to a pipe flange connection. When the plate radiator is damaged, only a damaged radiator needs to be replaced, without replacing the entire radiator, which greatly reduces the maintenance cost. However, this method also has shortcomings. One is that the plate radiator is usually filled with liquid during use. When a single radiator needs to be disassembled, the liquid inside the entire plate radiator needs to be released. After draining, the flange can be loosened to remove the radiator, which is inconvenient to disassemble. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a fin-pipe connector for a plate-type radiator, which solves the problem that it is inconvenient to disassemble and assemble the radiating fins of the prior plate-type radiator during maintenance.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fin-pipe connector for a plate-type radiator, comprising a heat dissipation fin and a spherical valve body, two pairs of mounting tubes are respectively connected to the two sides of the heat dissipation fin, the spherical valve body is connected to the mounting tube, connecting tubes are respectively provided at both ends of the spherical valve body, a piston column is provided inside the connecting tube, a cavity is provided inside the piston column, a plurality of first liquid guide ports and a second liquid guide port are respectively provided on the side walls at both ends of the cavity, a switch mechanism is provided in the spherical valve body, a flange ring is provided on the outer wall of the connecting tube, a plurality of bolts are provided on the flange ring, and a sealing mechanism is provided on the flange ring.

[0005] Preferably, the switching mechanism includes a bidirectional screw rod rotatably installed in the spherical valve body, both ends of the bidirectional screw rod are respectively screwed with circular rings, a pair of connecting rods are respectively hinged on the two side walls of the circular rings, one end of the two pairs of connecting rods is hinged with a pair of arc plates, one end of a pair of piston columns and located in the spherical valve body are respectively installed with arc guide plates, and a pair of arc plates are respectively connected to a pair of arc guide plates.

[0006] Preferably, the sealing mechanism includes a first annular groove opened in the side wall of the flange ring and a second annular groove in the inner wall of the flange ring, and a first sealing ring and a second sealing ring are respectively installed in the first annular groove and the second annular groove, the second sealing ring is sleeved on the outer wall of the connecting pipe and a conical sealing ring is provided on one side, and several of the bolts pass through the first sealing ring.

[0007] Preferably, the upper end of the bidirectional screw rod extends into the outside of the spherical valve body and is provided with a handle.

[0008] Beneficial Effects

[0009] The present invention provides a fin pipe connector for a plate-type radiator, which has the following beneficial effects:

[0010] Connecting pipes are respectively provided at both ends of the spherical valve body, and flange rings are sleeved on the outside of the connecting pipes. The spherical valve body is placed between the two heat dissipation fins, and then the flange rings on both sides of the spherical valve body are connected to the flanges of the mounting tubes on the heat dissipation fins by bolts. During the connection process, the conical sealing ring will be pushed by the flange ring between the inner wall of the mounting tube of the heat dissipation fin and the outer wall of the front end of the connecting pipe. As the flange ring and the flange connection of the mounting tube are completed, the mounting tube will be sleeved on the outside of the conical sealing ring to fix the connecting pipe through the conical sealing ring, and the first sealing ring and the second sealing ring will play a sealing role.

[0011] When working, turning the handle drives the two-way screw rod to rotate, so that a pair of circular rings move toward each other, and then pushes the arc guide plate to both sides through the connecting rod and the arc plate, so that the first liquid guide port of the piston column leaves the connecting pipe, and the heat sink is connected with the adjacent heat sink through the first liquid guide port, the cavity, the second liquid guide port and the spherical valve body. When the heat sink needs to be removed, the reverse turning of the handle drives the two-way screw rod to rotate in the opposite direction, so that the circular ring moves in the opposite direction, thereby pulling the piston column back into the connecting pipe, closing the first liquid guide port of the piston column, and then removing the bolts on the flange ring to replace the heat sink. The device can realize the disassembly and replacement of a single heat sink fin, and can also close two adjacent heat sink fins to avoid the release of liquid in the entire plate radiator. Only the liquid in the single heat sink needs to be released.

[0012] The design of the spherical valve body also has the function of blocking impurities. The first liquid guide port on the piston column and the arc-shaped guide plate in the spherical valve body can prevent larger impurity particles from flowing with the liquid in the plate radiator, thereby avoiding damage to the entire radiator.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-2 The present invention provides a technical solution: a fin-pipe connector of a plate-type radiator, comprising a heat dissipation fin 18 and a spherical valve body 1, two pairs of mounting tubes 19 are respectively connected to the two sides of the heat dissipation fin 18, the spherical valve body 1 is connected to the mounting tube 19, connecting tubes 14 are respectively provided at both ends of the spherical valve body 1, a piston column 8 is provided inside the connecting tube 14, a cavity 15 is provided inside the piston column 8, a plurality of first liquid guide ports 16 and a second liquid guide port 17 are respectively opened on the side walls at both ends of the cavity 15, a switch mechanism is provided inside the spherical valve body 1, a flange ring 9 is sleeved on the outer wall of the connecting tube 14, a plurality of bolts 11 are provided on the flange ring 9, and a sealing mechanism is provided on the flange ring 9;

[0018] In the current design of the fin type heat sink, the open end of each heat dissipating fin 18 is provided with a mounting tube 19, and each mounting tube 19 is provided with a flange, and the flange is used for connection. This structure belongs to the existing mature technology, so there is no need to describe the structure of the mounting tube 19 and the flange structure on the mounting tube 19 in detail;

[0019] The first liquid guide port 16 can prevent large granular impurities from entering the spherical valve body 1 , while the arc-shaped guide plate 6 can prevent the impurities entering the spherical valve body 1 from entering the heat dissipation fins 18 on the other side through the piston rod 8 .

[0020] Furthermore, the switch mechanism includes a bidirectional screw rod 2 rotatably installed in the spherical valve body 1, and circular rings 4 are respectively screwed on both ends of the bidirectional screw rod 2, and connecting rods 5 are respectively hinged on the two side walls of a pair of circular rings 4, and a pair of arc plates 7 are hinged at one end of the two pairs of connecting rods 5, and arc guide plates 6 are respectively installed at one end of a pair of piston columns 8 and located in the spherical valve body 1, and a pair of arc plates 7 are respectively connected to a pair of arc guide plates 6.

[0021] Furthermore, the sealing mechanism includes a first annular groove provided in the side wall of the flange ring 9 and a second annular groove provided in the inner wall of the flange ring 9, wherein a first sealing ring 10 and a second sealing ring 12 are respectively installed in the first annular groove and the second annular groove, and the second sealing ring 12 is sleeved on the outer wall of the connecting pipe 14 and a conical sealing ring 13 is provided on one side, and the plurality of bolts 11 all pass through the first sealing ring 10;

[0022] The conical sealing ring 13 is a metal ring with an inner circle and an outer cone. The spherical valve body 1 and the connecting pipes 14 at both ends are located between the mounting pipes 19 on a pair of heat dissipation fins 18, and are installed by screwing the bolts 11 on the flange ring 9 to the mounting pipes 19 (the mounting pipes of the heat dissipation fins have flanges that are known in the art). During the installation process, the outer diameter of the connecting pipe 14 is smaller than the inner diameter of the mounting pipe 19, but the connecting pipe 14 is not inserted into the mounting pipe 19, but a gap is left between the connecting pipe 14 and the mounting pipe 19. During the process of screwing the bolts 11 , the flange ring 9 will gradually approach the mounting tube 19, one end of the conical sealing ring 13 will gradually be inserted into the mounting tube 19, and the other end will tightly wrap the outer wall of the connecting tube 14. When the flange ring 9 and the flange of the mounting tube 19 are connected, the mounting tube 19 will wrap the tip of the conical sealing ring 13, so that the tail end of the conical sealing ring 13 will wrap the outer wall of the connecting tube 14 to complete the dual functions of sealing and fixing, while the first sealing ring 10 and the second sealing ring 12 simultaneously play the role of auxiliary sealing.

[0023] Furthermore, the upper end of the bidirectional screw rod 2 extends into the outside of the spherical valve body 1 and is provided with a handle 3 .

[0024] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0025] Embodiment: When in use, by rotating the handle 3 to drive the bidirectional screw 2 to rotate, the pair of rings 4 on the bidirectional screw 2 can be adjusted to move toward or in the opposite direction, and then the piston rod 8 is pulled to move left and right in the connecting pipe 14 through the hinged connecting rod 5 and the arc plate 7 and the arc guide plate 6. When the first liquid guide port 16 is exposed from the connecting pipe 14, the heat dissipation fin 18 is connected, otherwise it is closed. The flange ring 9 is connected to the mounting tube 19 (with its own connecting flange) on the heat dissipation fin 18 by bolts 11, which is convenient for disassembly and assembly.

[0026] A conduit 15 is connected to the air outlet of the support plate 5. When air is filled into the heat sinks 8, the air enters the conduit 15 and pushes the piston rod 18 to the right. The piston rod 18 pushes the push rod 19 and the connecting rod 20 to the right at the same time. The push rod 19 pushes the annular piston 23 to the right, thereby compressing the air at the right end of the conduit 15, so that the pressure gauge 16 displays the pressure indication, and the connecting rod 20 pushes the piston 22 to the right, pushing the hydraulic oil in the sleeve 24 from the metal tube 25 into the pressure tube 27, and squeezing the airbag 28 to make it Contraction. After the air pump 11 is stopped, if the pressure gauge 16 is in a stable state, it indicates that the heat sink 8 is intact. If the heat sink 8 has small cracks, the air in the heat sink 8 will slowly overflow from the cracks. At this time, the air bag 28 gradually expands and squeezes the hydraulic oil in the pressure tube 27 into the sleeve 24, and then pushes the piston 22 to the left. Then the piston 22 pushes the annular piston 23 to the left through the connecting rod 20, the piston column 18 and the push rod 19, so that the reading of the pressure gauge 16 gradually becomes smaller, indicating that the heat sink 8 is not intact.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
