Description

Technical Field

[0001] The invention relates to the technical field of cooling devices, and in particular to a cooler with a top indirect spraying device. Background Art

[0002] Coolers are a type of heat exchange equipment used to cool fluids. Usually water or air is used as a coolant to remove heat. They can be mainly divided into shell and tube coolers, plate coolers and air-cooled coolers. Coolers are heat exchange devices commonly used in industrial sectors such as metallurgy, chemical industry, energy, transportation, light industry, and food.

[0003] It is suitable for different working conditions such as cooling, condensing, heating, evaporation, and waste heat recovery. Therefore, among the many types of heat exchangers, coolers still occupy an important position.

[0004] At present, in order to form heat exchange, the cooler generally introduces the fluid to be cooled into the inner cavity of the cooler, and the heat exchange is formed by the fluid flowing inside the array tubes in the cooler. However, most of the existing coolers are directly introduced through pipes, so that a large amount of fluid to be cooled flows densely through the array pipes and flows down quickly. In this case, since the contact area between the fluid and the array tubes is limited, and heat exchange also takes time, when such a large amount of fluid is injected into the cooler at the same time, it is easy to cause incomplete heat exchange of the fluid, thereby failing to completely cool the fluid to the required temperature, which will affect the subsequent recovery and use of the fluid. Summary of the invention

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] Reference Figure 1-9 A cooler with an indirect top spray device is provided. In order to form an intermittent spraying effect inside the cooler and increase the spraying coverage area, it is convenient for the fluid to be cooled to contact and exchange heat with the heat exchange structure, that is, the array tube assembly 2 below. Here, it is provided to include a cooling box 1, an array tube assembly 2 for heat exchange is provided inside the cooling box 1, a pumping assembly 3 for pumping a hot fluid into the cooling box 1 is provided at the bottom of the cooling box 1, and a vertical channel 4 for concentrating the fluid is provided inside the cooling box 1;

[0036] The intermittent spray mechanism 5 includes a transverse pipe 51, an intermittent connecting nozzle 52, an extrusion steering mechanism 53 and a reset component 54. The transverse pipe 51 is arranged at the top of the internal cavity of the cooling box 1, and the transverse pipe 51 is connected to the pumping component 3. The intermittent connecting nozzle 52 is rotatably installed on the transverse pipe 51. The extrusion steering mechanism 53 is arranged on the top wall of the cooling box 1, and the extrusion end of the extrusion steering mechanism 53 acts on the intermittent connecting nozzle 52. The reset component 54 is arranged on the outside of the transverse pipe 51, and the reset component 54 is connected to the intermittent connecting nozzle 52. Through the joint action of the reset component 54 and the extrusion steering mechanism 53, the intermittent connecting nozzle 52 forms a cyclic reciprocating swinging state on the outside of the transverse pipe 51, forming intermittent reciprocating spraying.

[0037] The pumping assembly 3 includes an inlet pump 301, an inlet pipe 302 and an outlet pipe 303. The inlet pump 301 is arranged at the bottom of the cooling box 1 and is controlled by the control assembly. The inlet pipe 302 is arranged at one side of the cooling box 1, and one end of the inlet pipe 302 is connected to the inlet pump 301, and the other end passes through the side wall of the cooling box 1 and is connected to the transverse pipe 51. The outlet pipe 303 is arranged at the bottom of the cooling box 1 and can outlet the fluid gathered at the bottom of the cooling box 1.

[0038] Among them, the inlet pipe 302 is a three-way pipe, and one pipe inlet is connected to the inlet pump 301, and the two outlets both pass through the side wall of the cooling box body 1. Two intermittent spray mechanisms 5 are arranged at the top of the inner cavity of the cooling box body 1, and the transverse pipes 51 of the two intermittent spray mechanisms 5 are respectively connected to the two pipe outlets of the inlet pipe 302 passing through the side wall of the cooling box body 1.

[0039] The transverse pipe 51 is provided with a plurality of long grooves at equal intervals, and the intermittently connected nozzle 52 is arranged close to the outer side of the long grooves at intervals, so that when the intermittently connected nozzle 52 swings on the outer side of the transverse pipe 51, it will reciprocately sweep the long grooves at intervals on the transverse pipe 51, so that the intermittently connected nozzle 52 is intermittently connected with the transverse pipe 51, so that the liquid in the transverse pipe 51 can be intermittently sprayed through the intermittently connected nozzle 52, forming an intermittent spraying effect;

[0040] The wall of the transverse pipe 51 is provided with two long groove groups spaced apart along the wall, and the intermittently connected nozzles 52 are arranged outside the two long groove groups spaced apart along the wall of the transverse pipe 51, such as Figure 7 , Figure 8 and Fig. 9As shown, each long slot group includes a plurality of long slots spaced apart from each other, and the long slot groups at two locations on the same transverse pipe 51 and spaced apart along the pipe wall have their long slots staggered on the curved surface of the pipe wall. At the same time, the long slot groups at the same position of the two transverse pipes 51 also present a staggered distribution, so that when the two intermittently connected nozzles 52 on the same transverse pipe 51 are rotated to the same angle, one of the transverse pipes 51 can be connected to the transverse pipe 51 through the long slots, while the other transverse pipe 51 cannot be connected to the transverse pipe 51 through the long slots, so that the two intermittently connected nozzles 52 are alternately connected to the transverse pipe 51. Under the circumstances, when four different intermittently connected nozzles 52 rotate outside different long slot groups of two transverse pipes 51, due to the extrusion of the extrusion steering mechanism 53 and the resetting action of the resetting component 54, the four intermittently connected nozzles 52 will undergo a reciprocating pendulum rotation state on the two transverse pipes 51, and at the same time, the four intermittently connected nozzles 52 will present different rotation angles, so that the connection states of the four intermittently connected nozzles 52 and the corresponding long slot groups are regularly converted, so that the four intermittently connected nozzles 52 present regular intermittent spraying, so that the four intermittently connected nozzles 52 present a mutually staggered intermittent spraying state at the top of the inner cavity of the cooling box 1.

[0041] The intermittent connecting nozzle 52 includes a sealing sleeve 521 and a connecting nozzle 522. The sealing sleeve 521 is sleeved on the pipe of the transverse pipe 51 with long grooves distributed at intervals. The connecting nozzle 522 is arranged on the sealing sleeve 521, and the connecting port of the connecting nozzle 522 passes through the sealing sleeve 521 and fits the outer wall of the transverse pipe 51, so that when the sealing sleeve 521 fits the outer wall of the transverse pipe 51 and rotates, the connecting port of the connecting nozzle 522 will intermittently fit the long grooves distributed at intervals on the wall of the transverse pipe 51, so that the fluid in the transverse pipe 51 can intermittently enter the connecting nozzle 522 through the long grooves distributed at intervals and the connecting port.

[0042] The extrusion steering mechanism 53 includes a driving motor 531 and an eccentric extrusion wheel 532. The driving motor 531 is arranged at the end of the cooling box 1. The eccentric extrusion wheel 532 is installed at the end of the inner cavity of the cooling box 1 through a vertical rotating shaft and is rotatable in the horizontal direction. The rotating shaft of the eccentric extrusion wheel 532 is connected to the output end of the driving motor 531.

[0043] Among them, the eccentric extrusion wheel 532 and the four connecting nozzles 522 are all at the same level, and the edge of the eccentric extrusion wheel 532 squeezes the connecting nozzle 522, so that the eccentric extrusion wheel 532 will squeeze the connecting nozzle 522 and the sealing sleeve 521 to rotate outside the transverse pipe 51 when it rotates eccentrically. Since the eccentric extrusion wheel 532 rotates eccentrically, when the eccentric extrusion wheel 532 squeezes the four connecting nozzles 522 on the same plane, the positions at which the four connecting nozzles 522 contact the edge of the eccentric extrusion wheel 532 at the same time are all different, so that the angles at which the four connecting nozzles 522 are squeezed and rotated are all different. At this time, the four connecting nozzles 522 cover a wider area when spraying.

[0044] The reset assembly 54 includes a positioning collar 541 and a torsion spring 542. The positioning collar 541 is fixedly arranged on the outside of the transverse pipe 51, and the torsion spring 542 is arranged around the outside of the transverse pipe 51. One end of the torsion spring 542 is connected to the positioning collar 541, and the other end is connected to the sealing sleeve 521, so that the sealing sleeve 521 maintains a tendency to rotate toward one side of the extrusion steering mechanism 53, so that when the sealing sleeve 521 and the connecting nozzle 522 are squeezed and rotated by the eccentric extrusion wheel 532, when the eccentric extrusion wheel 532 rotates until it no longer squeezes the sealing sleeve 521 and the connecting nozzle 522, the reverse torque of the torsion spring 542 drives the sealing sleeve 521 and the connecting nozzle 522 to reset, so that the connecting nozzle 522 forms a reciprocating swinging state under the transverse pipe 51.

[0045] Furthermore, the vertical channel 4 is a channel that is wide at the top and bottom and narrow in the middle, and the vertical channel 4 is arranged in close contact with the inner cavity of the cooling box 1;

[0046] Among them, the array tube assembly 2 is arranged in the middle narrow channel of the vertical channel 4. Through the vertical channel 4 which is wide on the upper and lower sides and narrow in the middle, the fluid tends to flow toward the array tube assembly 2 in the middle of the vertical channel 4 during the flow process, which facilitates the array tube assembly 2 to perform heat exchange.

[0047] The array tube assembly 2 includes a positioning frame 201 and a circulation array tube 202. The positioning frame 201 is arranged in the middle narrow channel of the vertical channel 4, and the circulation array tube 202 is installed on the positioning frame 201.

[0048] Among them, the circulation array tube 202 includes a multi-layer heat exchange tube circulated and installed on the positioning frame 201, and a water inlet pipe and a water outlet pipe arranged at both ends of the heat exchange tube, and the water inlet pipe and the water outlet pipe of the circulation array tube 202 are connected to the outside through the vertical channel 4 and the side wall of the cooling box 1, and the intermittent spraying mechanism 5 is located above the wide channel above the vertical channel 4, and the outlet pipe 303 passes through the side wall of the cooling box 1 and is connected to the wide channel below the vertical channel 4, so that the fluid to be cooled intermittently sprayed by the intermittent spraying mechanism 5 passes through the circulation array tube 202 in the middle narrow channel of the vertical channel 4, and after completing the heat exchange, it flows into the outlet pipe 303 below for outlet.

[0049] Working principle: First, the water inlet pipe and the water outlet pipe of the circulation array pipe 202 are connected to the outside world respectively, and the heat-absorbing fluid passes through the water inlet pipe into the circulation array pipe 202 and flows out from the water outlet pipe. At this time, the fluid to be cooled is introduced into the two transverse pipes 51 at the top of the inner cavity of the cooling box 1 through the three-way introduction pipe 302 by the introduction pump 301. At this time, the driving motor 531 is started to drive the eccentric extrusion wheel 532 to rotate horizontally, and the eccentric extrusion wheel 532 will come into contact with the four intermittently connected nozzles 52 and squeeze the intermittently connected nozzles 52. The head 52 rotates on the transverse pipe 51. When the intermittent connecting nozzle 52 rotates, it squeezes the torsion spring 542 to twist, so that when the intermittent connecting nozzle 52 is no longer squeezed by the eccentric squeezing wheel 532, it will reset under the reverse torsion of the torsion spring 542. Since the wall of the transverse pipe 51 is provided with a plurality of long grooves with similar intervals, when the sealing sleeve 521 and the connecting nozzle 522 rotate on the transverse pipe 51, the connecting port of the connecting nozzle 522 will intermittently fit the long grooves with intervals on the wall of the transverse pipe 51, so that The fluid in the transverse pipe 51 can intermittently enter the connecting nozzle 522 through the long grooves and the connecting port that are distributed at intervals, so that the connecting nozzle 522 maintains an intermittent spraying state when spraying. Since the four intermittent connecting nozzles 52 are evenly distributed at the top of the inner cavity of the cooling box 1, and the positions where the four connecting nozzles 522 contact the edge of the eccentric extrusion wheel 532 at the same time are different, the angles at which the four connecting nozzles 522 are squeezed and rotated are different. At this time, the spraying coverage of the four connecting nozzles 522 is wider, and as the eccentric extrusion wheel 532 The four connecting nozzles 522 continuously rotate, and a continuous rotation reset and intermittent spraying state is formed above the vertical channel 4, so that the fluid to be cooled flows into the circulation array tube 202 in the middle of the vertical channel 4 evenly and intermittently. At this time, the fluid flowing through the circulation array tube 202 will form a heat exchange with the fluid to be cooled that is evenly sprayed and flows down from the outside of the circulation array tube 202, so that the fluid to be cooled is cooled and flows down to the bottom of the inner cavity of the cooling box 1 through the vertical channel 4. At this time, the outlet pipe 303 at the bottom of the cooling box 1 outlets the cooled fluid.
