[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] First of all, it should be noted that the above and below the text are all attached Figure 1 The current view direction prevails.
[0029] The utility model embodiment discloses a pressure tank, as shown in the attached Figures 1 to 5 As shown, it includes a tank body 1 and an insulation layer 2. The outer side surface of the tank body 1 is cylindrical, and one end is closed and the other end is open. A accommodating cavity is formed in the center of the tank body 1 for storing gas or liquid. If a fixing seat is set in the accommodating cavity, the fixing seat is L-shaped and is used to provide support for the installation of other equipment. The fixing seat can be fixed on the inner wall of the accommodating cavity by welding. The insulation layer 2 is annular, and the insulation layer 2 is sleeved on the outer side surface of the tank body 1 to insulate the tank body 1. The insulation layer 2 is composed of several layers of heat-insulating layers nested inside and outside, and each heat-insulating layer is made of heat-insulating material, such as heat-insulating cotton, and the thickness of each heat-insulating layer can reach 20 mm. Specifically, the insulation layer 2 is composed of two layers of heat-insulating cotton nested inside and outside. Of course, the structure and material of the insulation layer 2 are not limited to this.
[0030] A closed cooling chamber 3 is formed in the insulation layer 2. The cooling chamber 3 is annular and is formed between two insulation layers. It can completely cover the outer side of the tank body 1 to achieve the purpose of heat preservation. A plurality of partitions 4 are arranged in the cooling chamber 3. All the partitions 4 are used to divide the cooling flow channel 5 in the cooling chamber 3. Figure 1 As shown, the cooling medium flows along the cooling channel 5 and flows through the surface of the tank body 1, taking away the heat on the surface of the tank body 1, cooling the tank body 1, and effectively preventing the tank body 1 from overheating.
[0031] As attached Figure 1 As shown, the partition 4 includes a plurality of upper partitions 41 and a plurality of lower partitions 42, all of the upper partitions 41 are fixedly arranged at the upper end of the cooling cavity 3, and all of the lower partitions 42 are fixedly arranged at the lower end of the cooling cavity 3, and all of the upper partitions 41 and all of the lower partitions 42 can be fixed by welding or clamping. All of the upper partitions 41 and all of the lower partitions 42 are arranged at intervals, that is, a lower partition 42 is arranged between any two upper partitions 41, so that an axial flow channel 51 is formed between any adjacent upper partitions 41 and lower partitions 42, and all of the axial flow channels 51 are evenly distributed along the axial direction of the cooling cavity 3, so that the cooling medium flows along the axial direction of the cooling cavity 3 under the guidance of the axial flow channel 51. The length of all upper baffles 41 and the length of all lower baffles 42 are both smaller than the height of the cooling chamber 3. An upper guide channel 52 is formed between the upper end of the upper baffle 41 and the upper end of the cooling chamber 3, and a lower guide channel 53 is formed between the lower end of the lower baffle 42 and the lower end of the cooling chamber 3. Both the upper guide channel 52 and the lower guide channel 53 are U-shaped channels. Both ends of the axial channel 51 are respectively connected to the upper guide channel 52 and the lower guide channel 53, so that the cooling channel 5 becomes a serpentine channel extending along the circumference of the cooling chamber 3. The serpentine channel increases the heat exchange efficiency between the cooling medium and the tank body 1 by extending the flow path of the cooling medium, so that the cooling medium takes away more heat, ensuring that the cooling effect of the tank body 1 is optimal.
[0032] The lengths of all upper baffles 41 and all lower baffles 42 are equal, and there is no need to distinguish between the upper baffles 41 and the lower baffles 42 during assembly, which reduces the difficulty of assembly. Of course, the lengths of both the upper baffles 41 and the lower baffles 42 can be flexibly adjusted according to the heated area of the tank body 1. For example, in an area where the tank body 1 is severely heated, the lengths of the upper baffles 41 and the lower baffles 42 can be increased to extend the length of the cooling channel 5 to increase the heat exchange efficiency.
[0033] All upper baffles 41 and all lower baffles 42 are arranged parallel to the center line of the tank body 1, which makes it easier to install the upper baffles 41 and the lower baffles 42. Of course, all upper baffles 41 and all lower baffles 42 can also be arranged at an angle to the center line of the tank body 1, but all upper baffles 41 and all lower baffles 42 are still parallel to each other, and the purpose of the utility model is still achieved.
[0034] The spacing between any adjacent upper baffles 41 and lower baffles 42 is equal, so that the width of the cooling channel 5 remains constant, ensuring that the cooling medium flows stably in the cooling channel 5. Of course, the spacing between the upper baffles 41 and the lower baffles 42 can also be flexibly adjusted according to the heating conditions of the tank body 1. For example, in the area where the heating of the tank body 1 is more serious, the spacing between the upper baffles 41 and the lower baffles 42 can be reduced to extend the length of the cooling channel 5, so that the cooling medium heat exchange is more sufficient and more heat is taken away.
[0035] In addition to being arranged at equal intervals, the upper baffles 41 and the lower baffles 42 are arranged in a manner that the spacing between any adjacent upper baffles 41 and lower baffles 42 in the direction from the medium inlet 6 to the medium outlet 7 gradually decreases along the circumference of the cooling chamber 3. In other words, the closer to the medium outlet 7, the denser the upper baffles 41 and the lower baffles 42 are arranged. Considering that the temperature of the cooling medium near the medium outlet 7 is relatively high, the compact arrangement of the upper baffles 41 and the lower baffles 42 can improve the cooling effect at the outlet of the cooling channel 5 by further extending the length of the cooling channel 5, thereby ensuring that the heat dissipation at various locations of the tank body 1 is not very different, thereby ensuring that the internal temperature of the tank body 1 is uniform and avoiding excessive local temperature of the tank body 1.
[0036] The opposite sides of the cooling chamber 3 are provided with a medium inlet 6 and a medium outlet 7, respectively. The low-temperature cooling medium flows into the cooling chamber 3 from the medium inlet 6, and the high-temperature cooling medium after heat exchange is discharged from the medium outlet 7. Of course, the medium inlet 6 and the medium outlet 7 are provided on the same side of the cooling chamber 3, so that the cooling medium can flow completely through the surface of the tank body 1, and the heat exchange effect is better. The medium inlet 6 and the medium outlet 7 are provided at both ends of the cooling chamber 3, respectively, which can also ensure that the cooling medium flows completely through the surface of the tank body 1.
[0037] The cooling chamber 3 is preferably cooled by air, and a blower is added at the medium inlet 6 to blow low-temperature cold air into and out of the cooling chamber 3 from the medium inlet 6. Of course, the cooling chamber 3 can also be cooled by water, and a water pump can be provided at the medium inlet 6 to pump low-temperature cooling water into the cooling chamber 3 from the medium inlet 6.
[0038] The partition 4 includes a plurality of spiral partitions arranged around the circumference of the cooling chamber 3. A spiral flow channel is formed between any two adjacent spiral partitions, which can still ensure that the cooling medium flows through the surface of the tank body 1 along each spiral flow channel to cool the tank body 1. The widths of all spiral flow channels are equal to ensure that the cooling medium flows stably in each spiral flow channel. Of course, the setting of the spiral partition can be flexibly adjusted according to the heating condition of the tank body 1.
[0039] To further improve the cooling effect, at least one side of each partition 4 is provided with a heat dissipation fin or a heat dissipation protrusion to increase the heat dissipation efficiency by increasing the contact area between the partition 4 and the cooling medium.
[0040] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0041] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
