Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production, and in particular to a hydrogen compression cylinder and a hydrogen compressor. Background Art

[0002] Hydrogen is a clean energy source with a wide range of applications. Its production requires multiple pieces of equipment, a key component of which is the hydrogen compressor. This compressor compresses the produced hydrogen to reduce its volume and increase its density. Furthermore, the compressor removes moisture from the hydrogen through compression.

[0003] However, the compressor generates a lot of heat during the compression process. Most traditional treatment methods are to install cooling fins on the outside of the compressor. The heat dissipation method is single and the heat dissipation effect is limited. If the compressor cannot be cooled in time and is at a high temperature for a long time, the service life of the compressor will be greatly reduced.

[0004] Therefore, a device for rapidly cooling a compressor is now needed. Utility Model Content

[0005] Based on this, in order to solve the problem of excessively high compressor temperature, the present invention provides a hydrogen compression cylinder and a hydrogen compressor, and its specific technical solutions are as follows:

[0007] A water cooling assembly is sleeved outside the cylinder body, with cooling liquid flowing between the water cooling assembly and the cylinder body;

[0008] The fin heat dissipation assembly includes multiple heat sinks, a base and a fixing rod. The multiple heat sinks are fixedly connected to the base in sequence. The base is sleeved on the water cooling assembly. The fixing rod passes through one side of the base and is detachably fixed to the bracket at both ends.

[0009] Furthermore, the water cooling assembly includes a cooling tube sleeved outside the cylinder body, and two ends of the cooling tube are sealed and connected to two ends of the cylinder body.

[0010] Furthermore, a cooling groove is provided on a side of the cooling barrel facing the cylinder body, and the cooling groove cooperates with the cylinder body to form a cooling channel for circulating cooling liquid.

[0011] Furthermore, there are multiple cooling cylinders, each of which is provided with a liquid inlet and a liquid outlet. The liquid inlet of one cooling cylinder is connected to the liquid outlet of another cooling cylinder, and the liquid inlet and the liquid outlet are connected to the cooling tank.

[0012] Furthermore, the cooling groove is opened along the length direction of the cooling cylinder and is arranged in a serpentine shape.

[0013] Furthermore, the cooling groove is spirally opened on the inner wall of the cooling cylinder.

[0014] Furthermore, the cross section of the heat sink is arranged in a tree-like shape.

[0015] Furthermore, the heat sink and the base are integrally provided, and the water cooling assembly and the cylinder body are integrally provided.

[0016] A hydrogen compressor comprises a compression host and all the technical features of the above-mentioned hydrogen compression cylinder, wherein the compression host is connected to the hydrogen compressor.

[0017] Furthermore, the hydrogen compressor also includes an air cooling component, which is arranged on one side of the cylinder body, with the blowing end facing the fin heat dissipation component.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In the present invention, “first” and “second” do not represent specific quantities and orders, but are merely used to distinguish names.

[0031] like Figure 1 As shown in ˉ5, a hydrogen compression cylinder in one embodiment of the present invention includes a water-cooling component 4, which is sleeved on the outside of the cylinder body 2, and coolant flows between the water-cooling component 4 and the cylinder body 2; a fin heat dissipation component 5, which includes a plurality of heat sinks 51, a base 52 and a fixing rod 53, and the plurality of heat sinks 51 are fixedly connected to the base 52 in turn, and the base 52 is sleeved on the water-cooling component 4, and the fixing rod 53 passes through one side of the base 52, and both ends are detachably fixed to the bracket 1.

[0032] In one embodiment, when the piston 3 in the cylinder 2 begins to compress hydrogen due to friction, the friction between the cylinder 2 and the piston 3 causes the temperature of the cylinder 2 to gradually increase. This prolonged high temperature exposure of the cylinder 2 can shorten the life of the cylinder 2. The water-cooling assembly 4 is mounted on the outside of the cylinder 2, and coolant flowing through the water-cooling assembly 4 lowers the temperature of the cylinder 2. The fin heat sink assembly 5 further absorbs heat from the water-cooling assembly 4 and releases it to the surrounding environment, thereby lowering the temperature of the cylinder 2. Therefore, the water-cooling assembly 4 and the fin heat sink assembly 5 mounted on the cylinder 2 work together to efficiently cool the cylinder 2.

[0033] The water-cooling assembly 4, typically a cooling cylinder 41, is sleeved onto the cylinder body 2. A cooling channel for coolant flow is defined on the side of the water-cooling assembly 4 facing the cylinder body 2. This channel is formed by the water-cooling assembly 4 and the cylinder body 2, allowing the coolant to directly contact the outer wall of the cylinder body 2, absorbing heat generated by the cylinder body 2 and achieving a cooling effect. After the coolant absorbs heat from the cylinder body 2, its temperature rises. The finned heat sink 5, mounted on the water-cooling assembly 4, absorbs the coolant's heat and releases it to the surrounding environment.

[0034] A fan can be installed on one side of the water cooling assembly 4 and the fin heat dissipation assembly 5, with the blowing end of the fan facing the fin heat dissipation assembly 5, which can further accelerate the cooling of the fin heat dissipation assembly 5. The lowering of the temperature of the fin heat dissipation assembly 5 can accelerate the absorption of the temperature of the coolant, thereby lowering the temperature of the coolant. The lowering of the coolant temperature leads to a lowering of the temperature of the cylinder body 2.

[0035] In another embodiment, a water-cooling assembly 4 is wound around the cylinder body 2. The water-cooling assembly 4 includes a cooling pipe that is spirally wound around the cylinder body 2. Coolant in the cooling pipe flows continuously to remove heat from the cylinder body 2. Since the cooling pipe and the cylinder body 2 can be integrally provided, heat from the cylinder body 2 can be more easily transferred to the cooling pipe.

[0036] The base 52 can be integrated with the water cooling assembly 4 to increase heat conduction efficiency.

[0037] like Figure 1 As shown in FIG5 , in some embodiments, the water cooling assembly 4 includes a cooling tube 41 sleeved outside the cylinder body 2 , and both ends of the cooling tube 41 are sealed and connected to both ends of the cylinder body 2 .

[0038] In one embodiment, the water-cooling assembly 4 includes a cooling tube 41 connected to the cylinder body 2 at both ends. A sealed space is formed between the cooling tube 41 and the cylinder body 2, and coolant flows between the cooling tube 41 and the cylinder body 2. Because the coolant directly contacts the cylinder body 2, heat from the cylinder body 2 is more easily transferred to the coolant, thereby accelerating the cooling of the cylinder body 2.

[0039] It can be understood that the cooling cylinder 41 and the cylinder body 2 are integrally provided, thereby improving the airtightness of the cooling cylinder 41 and the cylinder body 2 and preventing the coolant from leaking out. Secondly, the integral provision of the cooling cylinder 41 and the cylinder body 2 can provide a better cooling effect on the cylinder body 2. Because the heat of the cylinder body 2 is not only transferred to the coolant, it can also be transferred to the cooling cylinder 41 itself. The heat of the fin heat sink assembly 5 provided on the cooling cylinder 41 will be absorbed by the fin heat sink assembly 5, thereby releasing the heat to the environment.

[0040] like Figure 1 As shown in FIG5 , in some embodiments, a cooling groove 411 is provided on a side of the cooling barrel 41 facing the cylinder body 2 , and the cooling groove 411 cooperates with the cylinder body 2 to form a cooling channel for circulating the coolant.

[0041] In one embodiment, a cooling groove 411 is provided on the contact surface between the cooling cylinder 41 and the cylinder body 2, and the cooling groove 411 and the cylinder body 2 cooperate to form a cooling channel. Reducing the activity space of the coolant can speed up the flow rate of the coolant. According to the definition formula of flow rate, the smaller the cross-sectional area of ​​the fluid, the faster its flow rate. Therefore, opening a cooling groove 411 for only coolant circulation is equivalent to reducing the flow space of the coolant, which can speed up the flow rate of the coolant. The coolant that has absorbed the heat of the cylinder body 2 will also leave the cooling channel faster to improve the cooling effect. If the cooling cylinder 41 and the cylinder body 2 are spaced apart, and coolant circulates between the cooling cylinder 41 and the cylinder body 2, the following problems will be faced:

[0042] The flow rate of the coolant is too slow. According to the definition formula of the flow rate, the larger the cross-sectional area of ​​the fluid, the greater the flow rate. The cooling tube 41 is circularly mounted on the cylinder body 2. Due to gravity, the coolant cannot flow to some parts of the cylinder body 2.

[0043] The loss of coolant increases because the circulation space of the coolant increases, the amount of coolant injected will also increase, and because its flow rate is too slow, the injection of coolant will be accelerated to achieve the cooling effect.

[0044] Therefore, it can be seen that after the cooling groove 411 is opened, not only the flow speed of the coolant can be accelerated, but also the consumption of the coolant can be reduced.

[0045] In another embodiment, a pipe for circulating coolant is provided inside the cooling cylinder 41 , and the cooling cylinder 41 is sleeved outside the cylinder body 2 .

[0046] In another embodiment, a cooling channel may be directly opened in the wall of the cylinder body 2 .

[0047] In another embodiment, the cooling cylinder 41 is cylindrical, with an opening on one side and a hinge on the other end. When the cooling cylinder 41 is mounted on the cylinder body 2, the opening is closed. To remove the cooling cylinder 41, the opening is opened and the cooling cylinder 41 is rotated around the hinge. Coolant circulates within the cooling cylinder 41, making cleaning and maintenance of the compression cylinder more convenient.

[0048] like Figure 1 As shown in FIG5 , in some embodiments, a plurality of cooling cylinders 41 are provided, each of which is provided with a liquid inlet 412 and a liquid outlet 413 . The liquid inlet 412 of one cooling cylinder 41 is connected to the liquid outlet 413 of another cooling cylinder 41 .

[0049] In one embodiment, multiple cooling cylinders 41 are provided, each of which is sleeved on the cylinder body 2. The cooling cylinders 41 are provided with a liquid inlet 412 and a liquid outlet 413 for coolant to carry heat and flow out of the cooling tank 411. The liquid inlet 412 of one cooling cylinder 41 is connected to the liquid outlet 413 of another cooling cylinder 41, ensuring flexible placement of the cooling cylinders 41.

[0050] like Figure 1 As shown in FIG5 , in some embodiments, the cooling groove 411 is opened along the length direction of the cooling cylinder 41 and is arranged in a serpentine shape.

[0051] In one embodiment, the liquid inlet 412 and the liquid outlet 413 of the cooling groove 411 are both opened at the top of the cooling cylinder 41 and are connected to the cooling groove 411. The cooling groove 411 extends in the forward direction along the length direction of the cooling cylinder 41 to one end of the cooling cylinder 41, then extends a distance along the arc direction of the cooling cylinder 41, and then extends in the reverse direction along the length direction of the cooling cylinder 41 to the other end of the cooling cylinder 41. In this way, the cooling groove 411 can be arranged in a serpentine shape on the side of the cooling cylinder 41 facing the cylinder body 2.

[0052] The distance extending in the arc direction of the cooling cylinder 41 can also be adjusted as needed to increase or decrease the contact area between the coolant and the cylinder body 2. The cooling groove 411 is arranged in a serpentine shape so that the temperature of the cylinder body 2 can be quickly cooled.

[0053] like Figure 1 As shown in FIG5 , in some embodiments, the cooling groove 411 is spirally opened on the inner wall of the cooling cylinder 41 .

[0054] In one embodiment, the cooling groove 411 is spirally arranged along the length direction of the cooling tube 41 . The spirally arranged cooling groove 411 has a faster circulation speed.

[0055] like Figure 1 As shown in FIG5 , in some embodiments, the cross section of the heat sink 51 is arranged in a tree-like shape.

[0056] In one embodiment, the cross-section of the heat sink 51 is dendritic, which makes it easier to cool the heat sink 51. Due to the dendritic arrangement, the size of each heat sink 51 is different. The heat sink 51 closer to the peripheral side is smaller and thinner, and heat can be more easily transferred out.

[0057] like Figure 1 As shown in FIG5 , in some embodiments, the heat sink 51 and the base 52 are integrally provided;

[0058] The water cooling assembly is integrated with the cylinder body 2.

[0059] In one embodiment, the integrated setting can make the heat conduction faster and the structure more stable. Secondly, the integrated setting can also regard the water cooling component as a part of the cylinder body 2, that is, the two can be produced together during the manufacturing process.

[0060] like Figure 1 As shown in ˉ5, a hydrogen compressor includes a compression host and all the technical features of the above-mentioned hydrogen compression cylinder, and the compression host is connected to the hydrogen compressor.

[0061] In one embodiment, the bracket 1 is provided with an air inlet and an air outlet, which are communicated with the compression space inside the cylinder 2 for transporting and collecting hydrogen.

[0062] In some embodiments, an air cooling component 6 is further included. The air cooling component 6 is arranged on one side of the cylinder body 2 , with the blowing end facing the fin heat dissipation component 5 .

[0063] In one embodiment, the air cooling component 6 can dissipate heat from the fin heat dissipation component 5 to further improve the cooling effect on the cylinder body 2 .

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
