Description

Technical Field

[0001] The utility model relates to a refrigeration device, in particular to a shell and tube condenser. Background Art

[0002] The shell and tube condenser generally includes a condenser shell, a compressor and other components. The shell is generally installed on a base frame, and a horizontal support plate is welded on the top side of the shell for mounting components such as the compressor on the support plate. When welding the support plate, since the top surface of the shell is an arc surface, in order to weld the support plate firmly, it is necessary to first weld a clip that fits the arc surface of the shell on the bottom side of the support plate, and use the clip plate to increase the contact area with the arc surface of the shell, thereby improving the stability of the support plate installation. This makes the production and assembly of the shell and tube condenser more troublesome, as it is necessary to produce and design clips that match the shapes of shells of different specifications, and then assemble and weld them. The production efficiency is low, and it is difficult to improve production benefits. Therefore, there is an urgent need for a shell and tube condenser that is easier to produce and assemble. Utility Model Content

[0003] The utility model aims to provide a shell and tube condenser to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A shell and tube condenser comprises: a base frame; a shell connected to the top side of the base frame, a condensing assembly is arranged in the shell; a support plate, which is located on the top side of the shell; a compressor, which is located above the support plate, a plurality of connecting legs are connected to the bottom side of the compressor, and the condensing assembly and the compressor are connected to each other through pipelines; a support unit, which comprises a connecting rod and a spring, the spring is located between one of the connecting legs and the support plate, one end of the connecting rod is connected to one of the support plates, and the other end of the connecting rod passes downward through the spring and the support plate in sequence and then is connected to the base frame, so that the two support units arranged in front and rear of the shell form a support group, and the support group is provided with a plurality of support units spaced apart in the left and right directions.

[0006] The technical solution has at least the following beneficial effects: the shell for installing the condensing component is relatively fixed on the base frame, and the support plate for supporting the compressor is directly connected to the base frame through a plurality of support units. For example, four connecting feet are connected to the bottom side of the compressor, and the four connecting feet are distributed in a rectangular shape on the bottom side of the compressor. A spring is arranged between the bottom side of each connecting foot and the top side of the support plate. The connecting rods connected to the bottom side of each connecting foot pass through the spring directly opposite to it, and then pass downward out of the support plate and are connected to the base frame. In this way, the four connecting rods distributed in a rectangular shape directly and relatively fix the compressor, the support plate, the shell and the base frame. There is no need to weld the support plate and the shell again, and there is no need to equip the shell with a clamping structure that is mutually compatible with the arc surface of the shell for shells of different specifications, which greatly improves the overall production and assembly efficiency. In addition, the multiple springs between the compressor and the support plate can provide buffering and support for the compressor, which can effectively reduce the mutual transmission of vibration generated when the compressor is working and vibration generated when the condensing component is working, thereby improving the stability and reliability of the whole machine when it is working.

[0007] As a further improvement of the above technical solution, the top end of the connecting rod passes through the connecting foot upward and is connected to the limiting head, and a screw hole is provided on the top side of the base frame, and the bottom end of the connecting rod is connected in the screw hole. The connecting rod and the connecting rod are split structures. When the two are assembled with each other, the connecting rod passes through the connecting foot, spring, and support plate from top to bottom, and then is connected to the screw hole of the base frame through threaded cooperation, and the limiting head at the top end of the connecting rod is used to press the connecting foot down and position it, so that the support unit can realize the mutual connection and positioning of the compressor, the support plate and the base frame.

[0008] As a further improvement of the above technical solution, the connecting rod is threadedly connected to a limiting cylinder, and the top end of the limiting cylinder abuts against the support plate. Before locking and positioning the multiple support units, the limiting cylinder is rotated to change the threaded matching position between the connecting rod and the limiting cylinder, so that the limiting cylinder moves upward relative to the connecting rod, and the top end of the limiting cylinder abuts against the support plate, so that the support plate is placed horizontally. At this time, the connecting rods in the multiple support units are repeatedly tightened, so that the supporting plate is supported by the limiting cylinder, which can facilitate the support and positioning of the support plate during installation.

[0009] As a further improvement of the above technical solution, an elastic ring is sleeved on the connecting rod, and the elastic ring is located between the limiting cylinder and the support plate. The limiting cylinder is against the bottom side of the support plate through the elastic ring, and the elastic ring can be used to buffer and offset the vibration directly transmitted downward from the support plate, avoiding the problem of noise generated by the vibration of the support plate and the collision between the limiting cylinder when the limiting cylinder directly abuts against the bottom side of the support plate, thereby further improving the stability and practicality of the whole machine during operation.

[0010] As a further improvement of the above technical solution, the support plate is provided with an avoidance hole for the connecting rod to pass through, and the inner diameter of the avoidance hole is larger than the outer diameter of the connecting rod. When the compressor is working and transmits vibration downward to the support plate, since the inner diameter of the avoidance hole on the support plate is larger than the outer diameter of the connecting rod, the support plate can be driven to produce slight movement, so that the vibration will not be directly transmitted downward to the shell, thereby further improving the stability of the whole machine when working.

[0011] As a further improvement of the above technical solution, a shock-absorbing pad is provided between the shell and the base frame. The condensing assembly in the shell will vibrate when working. Since the shell contacts the base frame through the shock-absorbing pad, the vibration directly transmitted to the base frame through the shell can be effectively reduced, thereby further improving the stability of the whole machine when working.

[0012] As a further improvement of the above technical solution, the bottom side of the support plate is connected with a plurality of convex ribs extending in the front-rear direction. The convex ribs can increase the anti-bending performance of the support plate and improve the stability of the support plate when subjected to stress for a long time.

[0013] As a further improvement of the above technical solution, a buffer pad is connected to the bottom side of the support plate, and a convex strip is arranged on the top side of the buffer pad at the position between two adjacent convex ribs. The bottom side of the support plate contacts the shell through the buffer pad, and the elastic buffering effect of the buffer pad can reduce the problem that the top side of the shell is easily crushed and deformed when the support plate directly contacts the top side of the shell, thereby improving the overall structural stability, and the convex strip on the top side of the buffer pad cooperates with the concave position formed between the two convex ribs on the bottom side of the support plate, thereby improving the tightness of the connection between the buffer pad and the support plate.

[0014] As a further improvement of the above technical solution, the condensing assembly includes a heat exchange tube connected to the shell, and the compressor is connected to one end of the heat exchange tube through a pipeline. When in use, the compressor transports heat exchange medium to the heat exchange tube through the pipeline, and the shell can transport liquid to exchange heat with the heat exchange tube.

[0015] As a further improvement of the above technical solution, a pulley is connected to the bottom side of the base frame, through which the whole machine can be conveniently moved, thereby improving the flexibility and convenience of the whole machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figure 1 and Figure 2A shell and tube condenser comprises a base frame 100, a shell 200, a support plate 300, a compressor 400 and a support unit, wherein the shell 200 is connected to the top side of the base frame 100, a condensing assembly is arranged in the shell 200, the support plate 300 is located on the top side of the shell 200, the compressor 400 is located above the support plate 300, a plurality of connecting pins 410 are connected to the bottom side of the compressor 400, the condensing assembly and the compressor 400 are connected to each other through a pipeline, and the support unit comprises a connecting rod 510 and a spring 520, the spring 520 is located on one of the connecting pins 410. 0 and the support plate 300, one end of the connecting rod 510 is connected to one of the support plates 300, and the other end of the connecting rod 510 passes through the spring 520 and the support plate 300 downward in sequence and is connected to the base frame 100, so that the two support units arranged in front and rear of the shell 200 are a support group, and a plurality of support groups are arranged at intervals along the left and right directions. For example, four connecting legs 410 are connected to the bottom side of the compressor 400, and the four connecting legs 410 are distributed in a rectangular shape. At this time, there are two corresponding support groups, and the four support units in the two support groups are also distributed in a rectangular shape.

[0026] As can be seen from the above, the shell 200 for installing the condensing assembly is relatively fixed on the base frame 100, and the support plate 300 for supporting the compressor 400 is directly connected to the base frame 100 through a plurality of support units. For example, four connecting legs 410 are connected to the bottom side of the compressor 400, and the four connecting legs 410 are distributed in a rectangular shape on the bottom side of the compressor 400. A spring 520 is arranged between the bottom side of each connecting leg 410 and the top side of the support plate 300. The connecting rod 510 connected to the bottom side of each connecting leg 410 passes through the spring 520 directly opposite to it, and then passes through the support plate 300 downward and is connected to the base frame 100. In this way, the four connecting legs 410 distributed in a rectangular shape are connected to the bottom side of the compressor 400. A connecting rod 510 directly and relatively fixes the compressor 400, the support plate 300, the shell 200 and the base frame 100. There is no need to weld the support plate 300 and the shell 200, and there is no need to equip the shell 200 with a clamping structure that is mutually compatible with the arc surface of the shell 200 for shells 200 of different specifications, which greatly improves the overall production and assembly efficiency. In addition, the multiple springs 520 between the compressor 400 and the support plate 300 can provide buffering and support for the compressor 400, which can effectively reduce the mutual transmission of vibrations generated by the compressor 400 when it is working and vibrations generated by the condensing component when it is working, thereby improving the stability and reliability of the entire machine when it is working.

[0027] In the above embodiment, the top of the connecting rod 510 can be directly fixed to the bottom of the connecting leg 410. In this case, the two need to be integrally formed during production, or the two need to be welded or screwed together to be locked and fixed together. In order to facilitate production and assembly, Figure 3As shown, in this embodiment, the top end of the connecting rod 510 passes through the connecting foot 410 upward and is connected to the limiting head 530. The top side of the base frame 100 is provided with a screw hole, and the bottom end of the connecting rod 510 is connected in the screw hole. The connecting rod 510 and the connecting rod 510 are split structures. When the two are assembled with each other, the connecting rod 510 passes through the connecting foot 410, the spring 520, and the support plate 300 from top to bottom, and then is connected to the screw hole of the base frame 100 through threaded cooperation. The limiting head 530 at the top end of the connecting rod 510 is used to press the connecting foot 410 downward to position it, so that the support unit can realize the mutual connection and positioning of the compressor 400, the support plate 300 and the base frame 100.

[0028] After the support plate 300 is horizontally positioned on the housing 200 by using multiple support units, in addition to relying on the housing 200 located below the middle of the support plate 300 to provide support for it, support can also be provided at the position of each connecting rod 510, thereby improving the stability of the installation of the support plate 300. Specifically, the connecting rod 510 is connected with a limiting cylinder 540 by threading, and the top of the limiting cylinder 540 abuts against the support plate 300. Before locking and positioning the multiple support units, the limiting cylinder 540 is rotated, and the threaded matching position between the connecting rod 510 and the limiting cylinder 540 is changed, so that the limiting cylinder 540 moves upward relative to the connecting rod 510, and the top of the limiting cylinder 540 abuts against the support plate 300, so that the support plate 300 is placed horizontally. At this time, the connecting rods 510 in the multiple support units are repeatedly tightened. In this way, the supporting plate 300 is supported by the limiting cylinder 540, which can facilitate the support and positioning of the support plate 300 during installation.

[0029] In the above embodiment, if the limiting cylinder 540 directly abuts against the bottom side of the support plate 300, when the compressor 400 is working, vibration is transmitted to the support plate 300, and when the support plate 300 vibrates, it will collide with the limiting cylinder 540, which is easy to generate noise and affect the stability of the limiting cylinder 540 installed on the support rod. Therefore, in this embodiment, an elastic ring 550 is sleeved on the connecting rod 510, and the elastic ring 550 is located between the limiting cylinder 540 and the support plate 300. The limiting cylinder 540 abuts against the bottom side of the support plate 300 through the elastic ring 550, and the elastic ring 550 can be used to buffer and offset the vibration directly transmitted downward from the support plate 300, so as to avoid the problem of noise generated by the vibration of the support plate 300 and the collision of the limiting cylinder 540 when the limiting cylinder 540 directly abuts against the bottom side of the support plate 300, thereby further improving the stability and practicality of the whole machine when it is working.

[0030] Since the connecting rod 510 needs to pass downward through the support plate 300, in the above embodiment, the support plate 300 may be processed with a hole reserved for the connecting rod 510 to pass through, while in this embodiment, the support plate 300 is provided with an avoidance hole for the connecting rod 510 to pass through, and the inner diameter of the avoidance hole is larger than the outer diameter of the connecting rod 510. When the compressor 400 transmits vibration downward to the support plate 300 during operation, since the inner diameter of the avoidance hole on the support plate 300 is larger than the outer diameter of the connecting rod 510, the support plate 300 can be driven to produce slight movement, so that the vibration will not be directly transmitted downward to the housing 200, thereby further improving the stability of the whole machine during operation.

[0031] In some embodiments, a shock-absorbing pad is provided between the housing 200 and the base frame 100. The condensing assembly in the housing 200 will vibrate during operation, and since the housing 200 is in contact with the base frame 100 through the shock-absorbing pad, the vibration directly transmitted to the base frame 100 through the housing 200 can be effectively reduced, thereby further improving the stability of the entire machine during operation.

[0032] In each support group, the support units located in front and rear of the shell 200 provide downward pulling force to the support plate 300. Since the top side of the shell 200 is usually also an arc-shaped surface that arches upward, the contact area between the shell 200 and the support plate 300 is small, and the support effect on the support plate 300 is poor. In order to improve the structural strength of the support plate 300, in this embodiment, a plurality of convex ribs extending in the front-to-back direction are connected to the bottom side of the support plate 300. The convex ribs can increase the anti-bending performance of the support plate 300 and improve the stability of the support plate 300 when it is subjected to force for a long time.

[0033] In order to reduce the small contact area between the support plate 300 and the shell 200, the pressure on the position where the top side of the shell 200 contacts the support plate 300 is too large, and in order to better protect the shell 200, in this embodiment, the bottom side of the support plate 300 is connected with a buffer pad 310, and the top side of the buffer pad 310 is provided with a convex strip corresponding to the position between two adjacent convex ribs. The bottom side of the support plate 300 contacts the shell 200 through the buffer pad 310, and the elastic buffering effect of the buffer pad 310 can reduce the problem that the top side of the shell 200 is easily crushed and deformed when the support plate 300 directly contacts the top side of the shell 200, thereby improving the overall structural stability, and the convex strip on the top side of the buffer pad 310 cooperates with the concave position formed between the two convex ribs on the bottom side of the support plate 300, thereby improving the tightness of the connection between the buffer pad 310 and the support plate 300.

[0034] As a further embodiment of the condensation component structure, the condensation component includes a heat exchange tube connected to the shell 200, and the compressor 400 is connected to one end of the heat exchange tube through a pipeline. In actual application, a plurality of fixed plates are arranged at intervals in the shell 200 along its length extension direction. When the heat exchange tube extends in the shell 200, it passes through the fixed plate, and the heat exchange tube is supported by the fixed plate. One end of the heat exchange tube is connected to one end of the shell 200 to form a heat exchange inlet, and the other end of the heat exchange tube is connected to the other end of the shell 200 to form a heat exchange outlet. When in use, the compressor 400 is connected to the heat exchange inlet through a pipeline to transport heat exchange medium to the heat exchange tube. At the heat exchange outlet, the compressor 400 is connected to an external expansion valve through a pipeline. The expansion valve is then connected to an external evaporator through a pipeline. The evaporator is then connected back to the compressor 400 through a pipeline, thereby forming a circulating refrigerant circuit. A water inlet is provided on one side of the shell 200, and a water outlet is provided on the other side of the shell 200. The water inlet and the water outlet are respectively connected to an external water supply device and a water storage device. Liquid is transported into the shell 200 through the water inlet to exchange heat with the heat exchange tube, so that the heat exchange tube is cooled down, and then the water is discharged outward from the water outlet.

[0035] In some embodiments, a pulley is connected to the bottom side of the base frame 100. The pulley on the bottom side of the base frame 100 can be used to conveniently move the entire machine, thereby improving the flexibility and convenience of using the entire machine. In practical applications, when the entire machine does not need to be moved, the pulley can be locked and braked to limit the rotation of the pulley.

[0036] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
