[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Example 1:

[0029] like Figures 1-2 As shown, Embodiment 1 of this utility model provides a surround-type cooler, including a tube bundle 1, a fixing assembly 2 for fixing the tube bundle 1, a rotating housing 3, and a driving device 4 for driving the rotating housing 3 to rotate.

[0030] The rotating housing 3 is cylindrical; if the rotating housing 3 is vertically arranged, the rotating housing 3 has a first through-hole 31 extending from the top to the bottom; the tube bundle 1 is fitted inside the rotating housing 3;

[0031] The fixing assembly 2 includes an upper tube sheet 21 and a lower tube sheet 22; the surfaces of the upper tube sheet 21 and the lower tube sheet 22 are both circular; the upper tube sheet 21 and the lower tube sheet 22 are horizontally arranged; the tube bundle 1 is vertically arranged; the two ends of the tube bundle 1 are fixed to the upper tube sheet 21 and the lower tube sheet 22 respectively; the top and bottom of the rotating housing 3 are adjacent to the lower surface of the upper tube sheet 21 and the upper surface of the lower tube sheet 22 respectively.

[0032] The rotating housing 3 has several air inlets 32 on its side wall; a guide plate 33 with an oblique angle to the air inlet 32 ​​is provided on the left side of the air inlet 32.

[0033] The drive unit 4 drives the rotating housing 3 to rotate.

[0034] When using the surround cooler provided in Embodiment 1 of this utility model, the hot fluid enters the tube bundle 1 from one end of the upper tube sheet 21 and exits the tube bundle 1 from one end of the lower tube sheet 22. When the hot fluid flows through the tube bundle 1, the rotating housing 3 is driven to rotate counterclockwise by the driving device 4, so that the surface of the air guide plate 33 contacts the surrounding air. The rotation introduces the surrounding air into the air inlet 32 ​​along the surface of the air guide plate 33. As the rotating housing 3 rotates, the position of the air inlet 32 ​​changes, and the rotating housing 3 introduces air from multiple angles, and the air surrounds and cools the tube bundle 1.

[0035] The surrounding cooler provided in Embodiment 1 of this utility model includes a tube bundle 1 and a fixing assembly 2. The fixing assembly 2 includes an upper tube sheet 21 and a lower tube sheet 22. Both ends of the tube bundle 1 are fixed to the upper tube sheet 21 and the lower tube sheet 22 respectively, thereby fixing a plurality of heat dissipation tubes in the tube bundle 1 together. It also includes a rotating housing 3 and a driving device 4. The tube bundle 1 is sleeved inside the rotating housing 3. The rotating housing 3 is located between the upper tube sheet 21 and the lower tube sheet 22. A plurality of air inlets 32 are opened on the side wall of the rotating housing 3, allowing air to enter the rotating housing 3 from the air inlets 32. At the same time, the driving device 4 drives the rotating housing 3. The rotating housing 3 rotates, allowing air to be introduced from multiple angles, thus enabling the air to circulate and cool the tube bundle 1 inside the rotating housing 3, improving the cooling efficiency of the air cooler. Furthermore, a guide plate 33 with an angled air inlet 32 ​​is provided on the left side of the air inlet 32. When the driving device 4 drives the rotating housing 3 to rotate counterclockwise, the guide plate 33 on the driving housing 3 can intercept the surrounding air. The rotation of the guide plate 33 allows the surrounding air to be introduced into the air inlet 32 ​​along the guide plate 33. Using the guide plate 33 can replace the induced draft fan in the prior art, reducing the manufacturing cost of the air cooler.

[0036] When using existing technology, there is a problem that the induced draft fan can only introduce airflow from one direction to cool the hot fluid in the tube bundle 1. The tube bundle 1 that is blocked cannot be cooled by the airflow, thereby reducing the cooling efficiency of the air cooler. The surrounding cooler provided in Embodiment 1 of this utility model is used to cool the tube bundle 1 inside the rotating housing 3. Several air inlets 32 are opened on the side wall of the rotating housing 3, and a guide plate 33 with an oblique angle to the air inlet 32 ​​is set on the left side of the air inlet 32. The driving device 4 drives the rotating housing 3 to rotate counterclockwise, so that the guide plate 33 rotates and the surrounding air is introduced into the air inlet 32 ​​along the guide plate 33. This achieves air surrounding and cooling of the tube bundle 1 in the rotating housing 3, thereby improving the cooling efficiency of the air cooler.

[0037] like Figure 2 As shown, in the surrounding cooler provided in Embodiment 1 of this utility model, preferably, when dust is adsorbed on the tube bundle 1, the contact area between the tube bundle 1 and the air is reduced, thereby reducing the cooling effect of the air on the tube bundle 1; for this purpose, the fixing component 2 also includes a filter cover 23, which can filter dust in the air, and the filter cover 23 can connect the upper tube plate 21 and the lower tube plate 22, thereby improving the fixing stability of several heat dissipation tubes in the tube bundle 1;

[0038] Specifically, the filter cover 23 is fitted inside the rotating housing 3. The filter cover 23 is cylindrical and vertically arranged. The filter cover 23 has a second through-hole 231 running from top to bottom. The tube bundle 1 is fitted inside the filter cover 23 through the second through-hole 231. Several vent holes 232 are provided on the side wall of the filter cover 23 to allow several heat dissipation tubes in the tube bundle 1 to come into contact with the air, while filtering dust brought in by the air, thereby reducing the amount of dust adsorbed on the surface of the tube bundle 1 and improving the cooling effect of the air on the tube bundle 1. The top of the filter cover 23 is fixed to the lower plate surface of the upper tube plate 21, and the bottom of the filter cover 23 is fixed to the upper plate surface of the lower tube plate 22. Since the two ends of the tube bundle 1 are fixed to the upper tube plate 21 and the lower tube plate 22 respectively, the filter cover 23 connects the upper tube plate 21 and the lower tube plate 22 together, which can improve the fixing stability of several heat dissipation tubes in the tube bundle 1.

[0039] like Figure 2 and Figure 5 As shown, in the embodiment 1 of this utility model, the surrounding cooler preferably includes a drive device 4 comprising a connecting bearing 41 and a first drive mechanism 42 to achieve relative rotation between the rotating housing 3 and the tube bundle 1. The connecting bearing 41 is disposed between the filter cover 23 and the rotating housing 3 to rotatably fix the rotating housing 3 and the filter cover 23. Further, the inner ring of the connecting bearing 41 is fixed to the outer wall of the filter cover 23, and the outer ring of the connecting bearing 41 is fixed to the inner wall of the rotating housing 3, thereby allowing the rotating housing 3 to rotate relative to the filter cover 23. The connecting bearing 41 is located near the top of the filter cover 23.

[0040] To drive the rotating housing 3 to rotate, more specifically, the first drive mechanism 42 includes a first motor 421, a drive gear 422, and a driven internal gear 423. The first motor 421 is fixed to the lower tube plate 22 with its shaft facing upwards. The drive gear 422 is fixed to the shaft of the first motor 421, and the axis of the drive gear 422 coincides with the axis of the shaft of the first motor 421. The driven internal gear 423 is fixed to the inner wall of the rotating housing 3, and the drive gear 422 and the driven internal gear 423 are meshed and connected. When the first motor 421 drives the shaft to rotate, the drive gear 422 is driven to rotate by the shaft of the first motor 421. Since the drive gear 422 and the driven internal gear 423 are meshed and connected, the rotation of the drive gear 422 drives the rotation of the driven internal gear 423. Since the driven internal gear 423 is fixed to the inner wall of the rotating housing 3, the rotation of the driven internal gear 423 drives the rotating housing 3 to rotate.

[0041] like Figure 2 and Figure 4As shown, the surround cooler provided in Embodiment 1 of this utility model preferably includes a cleaning component 5 to remove dust from the filter cover 23 in order to avoid reducing the air intake rate of the filter cover 23 due to clogging. Specifically, the cleaning component 5 includes a cleaning brush 51 and a second drive mechanism 52 for controlling the movement of the cleaning brush 51.

[0042] More specifically, the cleaning brush 51 includes a carrier 511 and several bristles. In order to remove dust from the filter cover 23 from all directions, the carrier 511 is made into a ring shape and all the bristles are evenly distributed on the outer wall of the carrier 511. The carrier 511 is placed inside the filter cover 23, and the tube bundle 1 is fitted inside the inner ring of the carrier 511. The outer wall of the carrier 511 is adjacent to the inner wall of the filter cover 23, so that the bristles can contact the filter cover 23. At the same time, the carrier 511 can have a movement space within the filter cover 23 to clean more parts of the filter cover 23.

[0043] The second drive mechanism 52 drives the carrier 511 to move vertically. The bristles on the carrier 511 contact and squeeze the air vents 232 on the filter cover 23, discharging the dust in the air vents 232 to the outside of the filter cover 23. The fallen dust can be discharged from the air cooler through the air inlet 32 ​​on the rotating housing 3.

[0044] like Figures 2-3 As shown, the surround-type cooler provided in Embodiment 1 of this utility model, preferably, in order to enable the second drive mechanism 52 to drive the carrier 511 to move in the vertical direction, specifically, the second drive mechanism 52 includes two cylinders 521; the cylinders 521 are fixed to the upper tube plate 21, the telescopic rods of the cylinders 521 face the lower tube plate 22, and the telescopic rods of the cylinders 521 are fixed to the top of the cleaning brush 51; when the telescopic rods of the cylinders 521 extend downward, the cleaning brush 51 moves towards the lower tube plate 22, and when the telescopic rods of the cylinders 521 retract upward, the cleaning brush 51 moves towards the upper tube plate 21, and the reciprocating motion of the cleaning brush 51 cleans the vent holes 232 on the filter cover 23.

[0045] In summary, the surround-type cooler provided by this utility model can solve the problem in the prior art where the induced draft fan can only introduce airflow from one direction to cool the hot fluid in the tube bundle, and the blocked tube bundle cannot be cooled by the airflow, thereby reducing the cooling efficiency of the air cooler. It can achieve surround cooling of the tube bundle and improve the cooling efficiency of the air cooler.
