Description

[0001] This application claims priority to the Chinese patent application for invention with the application number CN202510240352.2 and the filing date of 2025-03-03, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application belongs to the technical field of human micro-environment temperature regulation, and specifically relates to a matching structure and a matching method of a human heat exchange equipment shunt device and a flow collecting device. BACKGROUND

[0003] Many industry workers need to work in extreme temperature environments outdoors. Long-term work in high-temperature or low-temperature environments not only affects work efficiency, but also harms physical health. In order to protect the physical health of workers and improve work efficiency, it is necessary to equip personnel working in extreme temperature environments outdoors with human micro-environment temperature regulation equipment. The more effective method at present is to let the workers wear a specially designed garment covered with evenly distributed liquid circulation pipes. The circulation pipes are flexible, and the inner lining of the garment is in full contact with the outer surface of the human body. In a high-temperature working environment, cooled low-temperature liquid is allowed to flow through the circulation pipes, and the low-temperature liquid in the pipes exchanges heat with the outer surface of the human body, reducing the body surface temperature of the human body and improving the comfort of the human body. The liquid flowing out after heat exchange is cooled, and the cooled liquid is pumped into the garment pipe again by a circulating pump, and the cycle is repeated. In a low-temperature working environment, the liquid flowing into the pipe is heated high-temperature liquid, and the circulation process of the high-temperature liquid is similar to that of the low-temperature liquid, which will not be described again. That is, this heat exchange garment can be used for human body heating in low-temperature environments and human body cooling in high-temperature environments, and the more common application scenario is human body cooling in high-temperature environments.

[0004] There are many types of soft pipes that can be used in heat exchange garments, including silicone pipes and plastic soft pipes, and the most commonly used is flexible PVC (polyvinyl chloride) soft pipe. In heat exchange garments, a single loop structure with a pipe running from the beginning to the end is rarely used. This structure has many disadvantages, such as a long pipe, a large temperature difference between the beginning and the end, and an impact on the uniformity of the temperature in the heat exchange garment. A multi-loop structure with multiple liquid circulation pipes in parallel is commonly used. The circulating liquid from the cold / heat source flows into the input end of the heat exchange garment, and the liquid from the main pipe is distributed to the multiple parallel loops connected thereto through a shunt. After the circulating liquid completes heat exchange in the heat exchange garment, the liquid flowing out of each parallel loop is concentrated to the output main pipe through a flow collector, and the output main pipe is connected to the cold / heat source.

[0005] Ideally, heat exchange garments should have internal liquid circulation tubing that conforms perfectly to the body without restricting movement. This requires the tubing to exhibit good flexibility; from a heat exchange perspective, thinner walls are better. On the other hand, when heat exchange garments are worn, different parts of the tubing experience varying external pressures due to movement. Under these pressures, deformation of the tubing's lumen is undesirable, as it reduces the fluid cross-sectional area and hinders flow. This necessitates good rigidity in the tubing. Requiring both flexibility and rigidity is clearly contradictory, requiring a compromise. Current technologies mostly utilize PVC tubing with moderate wall thickness and rigidity.

[0006] For distributors / collectors used in liquid circulating heat exchange garments, the materials typically used are rigid plastics, such as polyamide (PA). One implementation of a distributor / collector is as follows: Figure 3 and Figure 4 As shown, Figure 4 yes Figure 3 A cross-sectional view. A central fluid conduction chamber connects all ports of the distributor / collector, with the inner bore of each port communicating with the central fluid conduction chamber. The ports have barbs on their outer sides. When the barbed ports of the distributor / collector are connected to the pipe hose, the barbed ports are inserted into the pipe hose bore. An example implementation... Figure 5 As shown, the third splitter / collector 300 has one main port and four sub-ports, namely: first sub-port 311, second sub-port 312, third sub-port 313, and fourth sub-port 314; the first main port 301 is connected to the third main pipe hose 33, and the first sub-port 311 is connected to the first circulation pipe hose 25.

[0007] The basic principle of the liquid-tight fit between the hose and the barbed port of the distributor / collector is that the outer diameter of the barbed port of the distributor / collector should be slightly larger than the inner diameter of the hose. This "slightly larger" amount is the interference fit, which causes the hose to generate a radial compressive force on the barbed port, and the hose and barbs to engage. The radial compressive force causes the inner wall of the hose to fit tightly against the conical surface of the barbed port, forming an initial seal; the barbed engagement forms a mechanical lock, preventing the hose from being pushed out or loosened under the pressure of the liquid inside the pipe or under external tension.

[0008] The barb height of the barb port matching the pipe hose is determined by multiple factors, including: the pipe diameter of the pipe hose, the wall thickness of the pipe hose, the hardness of the pipe hose. It is generally considered that the barb height of the barb port should not exceed the wall thickness of the pipe hose to be connected, and the barb height of the barb port is usually designed to be between 25% and 75% of the wall thickness of the pipe hose to be connected, so as to ensure that the port barb can reliably engage with the pipe hose, and the pipe hose is not pierced or torn by the port barb. As can be seen, the wall thickness of the pipe hose determines the barb height of the barb port to be connected; the thicker the wall thickness of the pipe hose, the greater the radial compression force it generates, and the better the liquid tightness at the connection of the barb port. Deeper barbs make the pipe hose less likely to come loose. For the pipe hose installed in the heat exchange garment, the wall thickness must first meet the heat exchange requirements and cannot be arbitrarily thickened, and it is not possible to increase the liquid tightness and anti-loose of the pipe hose at the connection of the barb port by adjusting the wall thickness of the pipe hose. The solution in the prior art is to apply a glue adhesive at the connection between the pipe hose and the barb port, and bond the two together; or lock the pipe hose on the port by a buckle.

[0009] By Figure 5 As can be seen, since the shunt / collector barb port has a certain wall thickness, the inner diameter of the port is significantly smaller than the inner diameter of the pipe hose to be inserted, and when the liquid flows from the pipe hose through the port of the shunt / collector, the resistance is generated due to the reduction of the fluid cross-sectional area, which affects the liquid flow velocity and thus the performance of the heat exchange garment.

[0010] In order to solve the problem of resistance to the liquid flowing caused by the mismatch of the inner diameters of the rigid shunt / collector and the pipe hose when they are connected, US20110095523A1 and US9399149B2 disclose a so-called improved shunt / collector. The basic principle is to change the structure of the shunt / collector, so that the inner diameter of the port is the same as that of the pipe hose to be connected, thereby avoiding the problem of resistance caused by the reduction of the fluid cross-sectional area when the liquid flows from the pipe hose through the port of the shunt / collector.

[0011] Each port of the improved shunt / collector has a proximal inner diameter and a distal inner diameter relative to the central fluid conducting chamber, the proximal inner diameter is the same as the inner diameter of the pipe hose to be connected, and the distal inner diameter is the same as the outer diameter of the pipe hose to be connected; a step surface is formed at the interface between the proximal inner diameter and the distal inner diameter, and the step surface becomes a stop when the end of the pipe hose is inserted into the hole cavity formed by the distal inner diameter. As can be clearly seen from the working principle, in an ideal state, there is no reduction of the fluid cross-sectional area when the liquid flows from the pipe hose through the port of the shunt / collector.

[0012] If the pipe hose is simply inserted into the distal cavity of the corresponding port of the flow distributor / collector, the connection is obviously unreliable; for this reason, the flow distributor / collector is made of flexible PVC material, which is the same as the material of the pipe hose; the compatibility between the two materials allows a reliable liquid-tight joint to be formed by means of known methods, including solvent bonding, ultrasonic welding, and radio frequency welding.

[0013] Since the flow distributor / collector is made of flexible PVC material, this non-rigid structure deforms when subjected to external forces, and the deformation of the cavity of the flexible flow distributor / collector causes the fluid cross-sectional area to decrease, and in the worst case, the cavity collapses completely and the flow is interrupted. In order to increase the rigidity of the flexible flow distributor / collector, the wall thickness of the flexible flow distributor / collector is increased, and four reinforcing ribs are added along the axis of the port on the outside of all the ports. Obviously, the increased rigidity of the flexible flow distributor / collector is related to the increase in the wall thickness and the increase in the width and height of the reinforcing ribs. This means that the increase in rigidity comes at the cost of an increase in the volume and the amount of material, both of which are undesirable. In practice, a trade-off must be made between rigidity and volume, or in other words, it is difficult to achieve 100% deformation of the cavity when the fluid flows through the flexible flow distributor / collector, which causes the fluid cross-sectional area to decrease. When the flexible flow distributor / collector is installed on the heat exchange garment, different extrusion forces are exerted on the flexible flow distributor / collector in different body postures of the wearer as the wearer moves freely.

[0014] As mentioned above, the pipe hose can be connected to the corresponding port of the flexible flow distributor / collector by means of solvent bonding or welding, which has the advantage of excellent liquid-tightness, but the disadvantage that it cannot be disassembled again during production and maintenance, but only destructively removed, which means an increase in production and maintenance costs.

[0015] In summary, in practical applications, it is difficult for the flexible flow distributor / collector to completely avoid resistance to the fluid flowing through it; compared to a rigid flow distributor / collector, the increase in size and the increase in the amount of material result in an increase in cost; the bonding or welding connection between the pipe hose and the flow distributor / collector cannot be disassembled again during production and maintenance, which causes trouble and an increase in cost.

[0016] There are also many problems for the common rigid shunt / collector. Since the inner diameter of the port is significantly smaller than the inner diameter of the pipe hose inserted therein, when the liquid flow passes through the port of the shunt / collector from the pipe hose, the resistance is generated due to the reduction of the fluid cross-sectional area, affecting the liquid flow speed. Since the wall thickness and hardness of the pipe hose cannot be arbitrarily selected, it is impossible to increase the liquid tightness and anti-loosening at the connection between the pipe hose and the port by adjusting the wall thickness of the pipe hose, and the pipe hose and the port can only be bonded together by applying a glue adhesive at the connection therebetween; or the pipe hose is locked on the port by a buckle; the flexibility at the connection between the pipe hose and the port cannot be arbitrarily adjusted. SUMMARY

[0017] Based on the shunt / collector of the prior art, whether rigid or flexible structure, there are different problems in the application in the liquid circulating heat exchange garment. A good solution should be that when the shunt / collector is connected to the liquid circulating pipe hose loop, no additional resistance is generated to the liquid flow passing therethrough; the outer shape and size should be small; when subjected to a certain external pressure, the cavity will not deform to reduce the fluid cross-sectional area; and it is easy to disassemble and assemble during production and maintenance.

[0018] The basic idea of the present application is that the shunt / collector adopts a rigid structure, and compared with the conventional rigid structure shunt / collector, the inner diameter of each barb port is enlarged, and the inner diameter of each barb port is the same as the inner diameter of the pipe hose to be connected thereto; obviously, the outer diameter of the barb port also increases accordingly. In this case, the size of the barb port of the shunt / collector no longer matches the size of the hole cavity of the pipe hose to be connected, and cannot be normally inserted. The further solution of the present application is to increase a matching device between the two, one end of the matching device is sleeved with the pipe hose, and the other end is inserted with the barb port of the corresponding shunt / collector. In another aspect, after the pipe hose end is sleeved with the matching device, the inner diameter of the pipe hose end is equivalent to being enlarged, so that the barb port of the shunt / collector with the increased outer diameter can be inserted therein. As can be seen, after the inner diameter of the barb port is enlarged and the matching device is added, when the liquid flow passes through the barb port of the shunt / collector from the pipe hose, there is no resistance generated due to the reduction of the fluid cross-sectional area.

[0019] The matching device is a flexible sleeve, which is compatible with the material of the pipe hose to be connected, and has the same inner diameter as the outer diameter of the pipe hose to be connected. The end of the pipe hose is placed in the hole cavity at one end of the flexible sleeve, and is tightly sleeved together. The outer diameter of the barb port of the flow distributor / flow collector is slightly larger than the inner diameter of the flexible sleeve. The "slightly larger" amount is the interference amount, so that the flexible sleeve generates a radial compression force on the barb port after insertion, and the flexible sleeve is engaged with the barb of the port. The radial compression force makes the inner wall of the flexible sleeve tightly fit on the tapered surface of the barb port, forming an initial seal; the barb engagement forms a mechanical lock to prevent the flexible sleeve from being pushed out or loosened under the pressure of the liquid in the pipe or the external pulling force.

[0020] Further, the matching device flexible sleeve has two end faces, a first end and a second end. The end of the pipe hose is placed in the hole cavity at the first end of the flexible sleeve, and is tightly sleeved together because the outer diameter of the pipe hose is the same as the inner diameter of the flexible sleeve. The material compatibility can form a reliable liquid-tight joint by existing methods, including solvent bonding, ultrasonic welding, and radio frequency welding. The second end of the flexible sleeve sleeved on the pipe hose is inserted into the corresponding barb port of the flow distributor / flow collector, which is located in the hole cavity of the flexible sleeve. Because the outer diameter of the barb port is slightly larger than the inner diameter of the flexible sleeve, a liquid-tight structure is formed by using the radial compression force of the flexible sleeve. Increasing the barb height of the port, the number of barbs, and increasing the wall thickness of the flexible sleeve can improve the liquid tightness and engagement force of the connection between the flexible sleeve and the barb port.

[0021] The pipe hose described in the present application is a general term for circulating pipe hoses and main pipe hoses. Under the premise of knowing the inner diameter, outer diameter, and material of the pipe hose, three aspects of work need to be done to realize its liquid flow resistance-free connection with the flow distributor / flow collector:

[0022] The first aspect is to construct a barb port of the flow distributor / flow collector that matches the inner diameter of the pipe hose. The inner diameter of the barb port is the same as the inner diameter of the pipe hose to be connected.

[0023] The second aspect is to construct a matching device flexible sleeve that matches the outer diameter of the pipe hose. The inner diameter of the flexible sleeve is the same as the outer diameter of the pipe hose to be connected.

[0024] The third aspect is to further optimize the barb structure of the flow distributor / flow collector, the wall thickness, hardness, and length of the flexible sleeve, and other related parameters, so that the wall thickness, hardness, and length of the flexible sleeve can effectively match the barb height, barb number, and barb spacing of the flow distributor / flow collector barb port, and a reliable liquid-tight structure can be formed after mutual insertion.

[0025] Since the pipeline hose and the matching device flexible sleeve are two independent components, the wall thickness and material hardness of the flexible sleeve can be selected independently of the wall thickness and material hardness of the pipeline hose; increasing the wall thickness of the flexible sleeve can increase the liquid tightness and occlusivity at the connection between the flexible sleeve and the barbed port; changing the material hardness of the flexible sleeve can change the flexibility at the connection between the flexible sleeve and the pipeline hose; this is a significant feature that distinguishes the present application from the prior art.

[0026] With the above working principle, the present application provides the following technical solutions:

[0027] A human body heat exchange equipment shunt device and a matching structure of a flow collecting device, the human body heat exchange equipment comprising: a garment main body, a liquid circulation pipeline hose loop, a shunt and a flow collector, input and output main pipeline hoses; the liquid circulation pipeline hose loop adopts a multi-loop structure with multiple paths in parallel; the shunt and the flow collector are rigid structures and are provided with at least one main port and multiple sub-ports; the ends of the liquid circulation pipeline hose loop are connected to the sub-ports of the shunt and the flow collector, and the input and output main pipeline hoses are connected to the main ports of the shunt and the flow collector; characterized in that the shunt and the flow collector are connected to the pipeline hose through a matching structure, and the matching structure comprises at least one barbed port of the rigid shunt and flow collector and a matching device.

[0028] The barbed port of the rigid shunt and flow collector is provided with a barb structure distributed along the axial direction on the outer side of each barbed port, and the inner diameter of each barbed port is the same as the inner diameter of the pipeline hose connected thereto.

[0029] The matching device is a flexible sleeve, the material of the flexible sleeve is compatible with the material of the pipeline hose connected thereto, and the inner diameter of the flexible sleeve is the same as the outer diameter of the pipeline hose connected thereto.

[0030] The flexible sleeve has two end faces, a first end and a second end; the end of the pipeline hose is placed in the hole cavity of the first end of the corresponding flexible sleeve and is tightly sleeved together; the second end of the flexible sleeve is inserted into the corresponding barbed port of the shunt and the flow collector, and the barbed port is located in the hole cavity of the flexible sleeve; the flexible sleeve and the barbed structure of the barbed port cooperate to form a liquid tight structure.

[0031] Further, the wall thickness of the flexible sleeve is the same as the wall thickness of the pipeline hose connected thereto, or is the wall thickness of a standard pipe material close to the wall thickness of the pipeline hose, i.e. wherein, is the wall thickness of the flexible sleeve, is the wall thickness of the pipeline hose connected to the flexible sleeve, the wall thickness of the flexible sleeve is increased to a predetermined value, i.e. , is a wall thickness adjustment coefficient, ; for non-standard pipe materials, the wall thickness is increased to a predetermined value, i.e. , is a wall thickness increase value, .

[0032] Further, the hardness of the flexible sleeve is selected to be the same as that of the pipe hose to which it is connected, or the hardness of the flexible sleeve is reduced to improve flexibility; the reduction in the liquid tightness and the engagement force at the connection of the barbed port caused by the reduction in the material hardness of the flexible sleeve is compensated by various methods, including: increasing the wall thickness of the flexible sleeve increasing the barb height of the barbed port .

[0033] Further, the number of barbs of the barbed port is preferably: the main port , the sub-port ; the more the number of barbs of the barbed port, the better the liquid tightness and the engagement force at the connection of the barbed port and the flexible sleeve; when the liquid tightness and the engagement force at the connection of the barbed port and the flexible sleeve are not enough, the number of barbs of the barbed port is increased to compensate for the reduction in the liquid tightness and the engagement force at the connection of the barbed port; for example, the reduction in the wall thickness of the flexible sleeve or the reduction in the material hardness of the flexible sleeve can be compensated by increasing the number of barbs of one or two barbed ports.

[0034] Further, the higher the barb height of the barbed port, the better the liquid tightness and the engagement force at the connection of the barbed port and the flexible sleeve; it is generally considered that the barb height of the barbed port should not exceed the wall thickness of the flexible sleeve to which it is connected, and the barb height is usually set to be 0.25 to 0.75 times the wall thickness of the flexible sleeve to which it is connected; the barb height of the main port is preferably 0.5 times the wall thickness of the flexible sleeve to which it is connected, and the barb height of the sub-port is preferably 0.4 times the wall thickness of the flexible sleeve to which it is connected. Therefore, the relationship between the barb height and the wall thickness of the flexible sleeve is: wherein, is the barb height of the barbed port, is the wall thickness of the flexible sleeve to which the barbed port is connected, is a proportionality coefficient, preferably for the main port, and preferably for the sub-port. , the value range is .

[0035] Further, the outer diameter of the barb port of the flow divider and flow collector at the barb valley is the same as the outer diameter of the pipeline hose, or the outer diameter of the barb port at the barb valley is increased to increase the minimum wall thickness of the barb port at the barb valley , to improve the mechanical strength at the minimum wall thickness, to meet , and , wherein, is the wall thickness of the pipeline hose, is the wall thickness increment, is the barb height.

[0036] Further, the barb spacing of the barb port is generally designed to be about 3.8 mm; according to needs, the barb spacing of the barb port can be adjusted, and generally the barb spacing rarely exceeds 8 mm; in the case that the port length of the barb port is limited and the number of barbs cannot be reduced, the barb spacing of the barb port can be reduced, and generally the wall thickness value of the flexible sleeve connected with the barb port is taken as the minimum limit value of the barb spacing. Therefore, the barb spacing of the barb port of the flow divider and flow collector is: , and the preferred value is 3.8 mm, wherein, is the barb spacing of adjacent barbs, is the wall thickness of the flexible sleeve connected therewith.

[0037] Further, the length of the flexible sleeve is which is the sum of the three relevant length values, i.e. , wherein, is the port length of the barb port of the flow divider and flow collector connected therewith, is the bridging gap between the end side of the barb port and the end side of the pipeline hose, is the sleeving length between the flexible sleeve and the pipeline hose.

[0038] Further, the end of the flexible sleeve and the end of the pipeline hose are tightly sleeved together to form a reliable liquid-tight joint by utilizing the compatibility of the materials, and the method for forming a reliable liquid-tight joint includes solvent bonding, ultrasonic welding, and radio frequency welding.

[0039] The principle of the present application is to, under the premise of known pipeline hose inner diameter, outer diameter and material quality, by configuring the flexible sleeve and the barb port of the flow divider / flow collector, so that when the liquid flow passes through the port of the flow divider / flow collector from the pipeline hose, there is no reduction in the fluid cross-sectional area. The configuration and matching method process includes the following steps:

[0040] Step S10: Constructing the barb port of the flow divider and flow collector

[0041] (a) Determine the inner diameter of the barb port: according to the inner diameter of the pipe hose to be connected , set the inner diameter of the barb port , and the inner diameter tolerance is ±0.1 mm;

[0042] (b) Determine the outer diameter of the barb port at the barb valley: the outer diameter of the barb port of the flow divider and flow collector at the barb valley , is the outer diameter of the pipe hose to be connected thereto; or by increasing the outer diameter of the barb port at the barb valley to increase the minimum wall thickness of the barb port at the barb valley to improve the mechanical strength thereof at the minimum wall thickness, to meet , and , wherein, is the wall thickness of the pipe hose to be connected thereto, is the wall thickness increment, is the barb height of the barb port;

[0043] (c) Determine the barb height of the barb port: according to , calculate the barb height of the barb port of the flow divider and flow collector, wherein, is the barb height of the barb port, is the wall thickness of the flexible sleeve to be connected thereto, is the proportionality coefficient, preferably of the main port, preferably of the sub-port, and the value range is ;

[0044] (d) Determine the number of barbs of the barb port: preferably the number of barbs of the main port , preferably the number of barbs of the sub-port , and the number of barbs can be adjusted to meet the bite force requirement ;

[0045] (e) Set the barb spacing of the barb port: , preferably 3.8 mm, wherein, is the barb spacing of adjacent barbs, is the wall thickness value of the flexible sleeve to be connected thereto;

[0046] (f) Forming: according to the parameters of steps (a)-(e), calculate the outer diameter of the barb port at the barb peak and the port length; the inner diameter, the outer diameter at the barb valley, the outer diameter at the barb peak, the number of barbs, and the barb spacing of the barb port are all clear, and the barb port of the flow divider and flow collector is constructed;

[0047] Step S20: Constructing the flexible sleeve

[0048] (a) Selecting compatible materials: the material of the flexible sleeve is compatible with the material of the pipeline hose to be connected;

[0049] (b) Determining the inner diameter of the flexible sleeve: the inner diameter of the flexible sleeve is set to be , the outer diameter of the pipeline hose to be connected;

[0050] (c) Determining the wall thickness of the flexible sleeve: the wall thickness of the flexible sleeve is set to be , wherein is the wall thickness of the pipeline hose to be connected to the flexible sleeve, is the wall thickness of the standard pipe material close to the wall thickness of the pipeline hose; when the liquid tightness and the engagement force at the barb port connection of the flexible sleeve are insufficient, or when the hardness of the flexible sleeve needs to be reduced to maintain its radial compression force and engagement force, the wall thickness of the flexible sleeve is increased: for standard pipe materials, the wall thickness of the flexible sleeve is preferably increased by 0.5 mm each time, i.e. , wherein is the wall thickness adjustment coefficient, ; for non-standard pipe materials, the wall thickness is increased to a predetermined value, i.e. , wherein is the wall thickness increase value, ;

[0051] (d) Determining the hardness of the flexible sleeve: the hardness of the flexible sleeve is selected to be the same as the hardness of the pipeline hose to be connected, or the hardness of the flexible sleeve is reduced to improve flexibility; if the hardness of the flexible sleeve is reduced, its liquid tightness and engagement force at the barb port connection are compensated by increasing the barb height of the barb port , increasing the number of barbs of the barb port , and increasing the wall thickness of the flexible sleeve ;

[0052] (e) Calculating the length of the flexible sleeve: , wherein is the length of the flexible sleeve, is the length of the port of the barb port of the shunt and the manifold to be connected, is the bridging gap between the end side of the barb port and the end side of the pipeline hose, is the sleeving length between the flexible sleeve and the pipeline hose;

[0053] (f) The flexible sleeve is thus finalized: all parameters of the flexible sleeve, including the inner diameter, the outer diameter, the length, the hardness, and the material, are determined, and the flexible sleeve is constructed;

[0054] Step S30: Assembling and fixing the flexible sleeve and the flow distributor and flow collector constructed in steps S10 and S20

[0055] (a) Pipe hose and flexible sleeve tight connection: Put the end of the pipe hose into the hole of the corresponding end of the flexible sleeve, tightly connect them together, adjust the interface of the two to the length required by the used tight connection process, and connect them together by the selected tight connection process, which includes solvent bonding, ultrasonic welding, and radio frequency welding;

[0056] (b) Flexible sleeve and barb port insertion: Insert the other end of the flexible sleeve assembled on the pipe hose into the corresponding barb port of the flow distributor and flow collector, and the barb port is located in the hole of the flexible sleeve and is inserted into the root of the barb port to form a mechanical bite and a liquid-tight seal by the barb structure;

[0057] (c) Overall fixation: After completing the connection of all pipe hoses to the corresponding barb ports of the flow distributor and flow collector, install and fix the flow distributor and flow collector to the predetermined position of the heat exchange garment.

[0058] As mentioned above, the inner diameter of the flow distributor / flow collector barb port is required to be the same as that of the pipe hose connected thereto, and there is an error in engineering. As long as the inner diameters of the two are close, they are connected together by the flexible sleeve, which belongs to the protection scope of the present application. Even if the resistance to the liquid flow at the port connection is not completely eliminated, it is minimized. Similarly, the present application requires that the two corresponding sizes be the same in many other places. In order to facilitate the description of the theoretical principles, as long as the sizes of the two are basically close in actual engineering, the connection method using the sleeve belongs to the protection scope of the present application.

[0059] In one embodiment, only part of the ports in the flow distributor / flow collector are connected to the pipe hose using the sleeve connection technology of the present application, and the connection of the remaining ports uses conventional technology; for example, the main pipe hose has a relatively large diameter, and the connection with the main port uses the conventional direct insertion method, while the connection between the circulating pipe hose and the sub-port uses the sleeve connection technology of the present application. It cannot be excluded from the protection scope of the present application just because only part of the ports use the sleeve connection technology of the present application. As long as one port uses the sleeve connection technology of the present application, it belongs to the protection scope of the present application.

[0060] In one embodiment, in order to further enhance the liquid tightness and prevent the sleeve from falling off at the connection between the flexible sleeve and the barb port, the flexible sleeve is locked on the port by a tie, which still belongs to the protection scope of the present application.

[0061] In one embodiment, to further enhance the liquid tightness and prevent the sleeve from falling off at the connection between the flexible sleeve and the barbed port, an adhesive is applied at the interface between the outside of the port and the inside of the flexible sleeve, and the two are bonded together, which also belongs to the protection scope of the present application.

[0062] The present application has many advantages:

[0063] 1. In terms of structural design, the present application adopts a transition connection mode of rigid shunt / collector cooperating with an independent flexible sleeve, replacing the traditional single rigid or fully flexible structure. The inner diameter of the barbed port of the shunt / collector is strictly consistent with the inner diameter of the pipeline hose, with a tolerance controlled within ±0.1 mm, ensuring that the liquid flow from the pipeline hose through the port will not produce resistance due to the reduction of fluid cross-sectional area, fundamentally solving the problem of liquid flow resistance caused by the mismatch of inner diameter of the traditional rigid shunt. The flexible sleeve, as an independent component, is sleeved with the pipeline hose and the barbed port at both ends, and its wall thickness and hardness can be adjusted according to actual needs. When the hardness of the flexible sleeve is reduced, the wall thickness can be increased to compensate for the decrease in radial compression force, so as to balance the flexibility and liquid tightness at the connection between the flexible sleeve and the barbed port, avoiding the defect that the fully flexible shunt / collector is easily deformed due to insufficient rigidity, and realizing the dual goals of non-resistance liquid flow transmission and structural stability for the first time.

[0064] 2. The parametric design of the barbed port is another core of the present application. The barb height is determined by the product of the wall thickness of the flexible sleeve and the proportionality coefficient, and the proportionality coefficient is in the range of 0.25 to 0.75, which not only ensures sufficient engagement force, but also avoids the problem of flexible sleeve puncture or connection loosening caused by fixed barb height. The number of barbs is configured differently according to the type of port: 2-3 for the main port and 1-2 for the sub-port, to match the pipe diameter and stress requirements of different ports; the barb spacing is controlled between the wall thickness of the flexible sleeve and 8 mm (preferably 3.8 mm), which balances stress dispersion and engagement strength through reasonable spacing design, ensuring that fatigue damage will not occur due to stress concentration in long-term use.

[0065] 3. The independent adjustment mechanism of the flexible sleeve further improves the versatility and flexibility of the matching device. As an intermediate transition piece connecting the pipeline hose and the shunt / collector, the flexible sleeve can be independently selected in terms of wall thickness and hardness, without changing the parameters of the pipeline hose or the shunt / collector, to realize reliable liquid-tight butt joint. The specific adjustment methods include: when the hardness of the flexible sleeve is unchanged, the wall thickness of the flexible sleeve can be increased to improve its liquid tightness and engagement force at the connection with the barbed port; when the hardness of the flexible sleeve is reduced to improve the flexibility of the pipeline hose at the connection with the barbed port, the wall thickness of the flexible sleeve can be increased to compensate for the decrease in its radial compression force, maintain its liquid tightness and engagement force at the barbed port, and improve its flexibility at the connection with the hose to adapt to complex installation environments.

[0066] 4. The barb port of the shunt / collector is designed in coordination with the parameters of the flexible sleeve. Increasing the wall thickness of the flexible sleeve can improve its liquid tightness and bite force at the connection with the barb port; when the hardness of the flexible sleeve is reduced to improve flexibility, the liquid tightness and bite force at the connection with the barb port can be compensated by increasing the wall thickness of the flexible sleeve, increasing the height of the barbs of the barb port, and increasing the number of barbs of the barb port.

[0067] 5. In the connection process and maintenance design, the pipe hose and the flexible sleeve are connected by solvent bonding or welding, and the flexible sleeve and the barb port are double-sealed by mechanical bite without the need for additional clamping devices. Compared with the rigid shunt / collector of the prior art, the shunt / collector of the present application only needs to adjust the port size, and the rest of the volume remains unchanged; compared with the flexible shunt / collector, the device has a smaller size, and when subjected to external force, the liquid flow resistance caused by the deformation of the cavity is avoided. The detachable plug-in design supports secondary disassembly, solving the problem of the need for overall replacement during maintenance of the traditional bonding or welding structure, and effectively reducing the total life cycle cost.

[0068] Through the above design, the technical bottleneck of rigid resistance and flexible instability is successfully broken, and the unity of liquid flow transmission efficiency, structural stability, and maintenance convenience is achieved. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0081] As used herein, "body heat exchange device" or "heat exchange clothing" refers to wearable clothing items, including vests, jackets, sleeves, coats, shirts, suits, trousers, work clothes, headscarves, hats, boots, gloves, and any other type of complete or partial body covering, including blankets or tarpaulins. It can be configured to support tubing in close contact with the body to carry circulating fluid, thereby controlling body temperature through the cooling or heating of the circulating fluid.

[0082] As used herein, the terms “first,” “second,” “third,” “fourth,” “fifth,” “sixth,” “seventh,” and “eighth” are used to describe various parts, but these parts are not limited by these terms. These terms are only used to distinguish one part of the same class from the rest of the parts and should not be construed as indicating or implying relative importance.

[0083] As used in this article, pipe hose is a general term for liquid circulation pipe hose and main pipe hose.

[0084] Figure 1 and Figure 2 This is a schematic diagram of one embodiment of heat exchange garment. Figure 1 This is a front view. Figure 2is a back view, showing a heat exchange vest. Heat exchange clothing is generally composed of an inner lining fabric, a middle liquid circulating tube and an outer fabric. In order to see the structure of the inner liquid circulating tube, we hide the outer fabric.

[0085] The heat exchange vest includes a vest body 1, four liquid circulating tube loops, two distributors / collectors and two circulating liquid input / output main tube loops connected to a cooling / heating source. The four liquid circulating tube loops include a left front liquid circulating tube loop 21, a right front liquid circulating tube loop 22, a left rear liquid circulating tube loop 23 and a right rear liquid circulating tube loop 24; the two distributors / collectors include a first distributor / collector 100 and a second distributor / collector 200; the two input / output main tube loops include a first input / output main tube loop 31 and a second input / output main tube loop 32.

[0086] In a multi-liquid circulating tube path and parallel multi-loop heat exchange clothing, distributors and collectors are essential accessories. When the first input / output main tube loop 31 is input and the second input / output main tube loop 32 is output, the first distributor / collector 100 becomes a distributor and the second distributor / collector 200 becomes a collector; conversely, when the second input / output main tube loop 32 is input and the first input / output main tube loop 31 is output, the second distributor / collector 200 becomes a distributor and the first distributor / collector 100 becomes a collector. The same accessory can be a distributor or a collector, and the role is determined by the direction of the liquid flow.

[0087] There are many kinds of rigid distributors / collectors, in addition to Figure 3 the third distributor / collector 300 shown in the figure, the commonly used structure of the distributor / collector also has the fourth distributor / collector 400 shown in Figure 6 and the fifth distributor / collector 500 shown in Figure 7 Some distributors / collectors are designed with double-row sub-ports, and even some sub-ports are at an angle with the central fluid conduction chamber. The examples of distributors / collectors given here are all one main port and four sub-ports, only for the convenience of principle description, and are not a limitation of the invention, and the invention is applicable to any number of ports of the distributor / collector. In an application, what kind of structure of the distributor / collector is selected depends on the number of tube loops to be connected, the direction and position of the end of the tube loop, and the principles of smoothness of connection, liquid tightness and reliability after connection with the tube loop.

[0088] Next, take the third distributor / collector 300 as an example to further describe the structure of the relevant ports. As shown inFigure 4 As shown, the third flow distributor / collector 300 is composed of one main port and four sub-ports, and the four sub-ports are identical in structure, and we only take one of them as an example for illustration.

[0089] For the first main port 301, the inner diameter of the port is d21, the outer diameter of the port barb valley is d22, the outer diameter of the port barb peak is d23, and the barb height is (d23-d22) / 2. As can be seen, when the inner diameter d21 of the first main port 301 is a constant value, the outer diameter d22 of the port barb valley determines the minimum wall thickness of the port, thereby determining the mechanical strength of the first main port 301. Usually, the value of the outer diameter d22 of the port barb valley is selected to be the same as the inner diameter value of the main pipe hose to be connected, and thus the value of the outer diameter d23 of the first main port 301 barb peak determines the barb height.

[0090] For the first sub-port 311, the inner diameter of the port is d11, the outer diameter of the port barb valley is d12, the outer diameter of the port barb peak is d13, and the barb height is (d13-d12) / 2. As can be seen, when the inner diameter d11 of the first sub-port 311 is a constant value, the outer diameter d12 of the port barb valley determines the minimum wall thickness of the port, thereby determining the mechanical strength of the first sub-port 311. Usually, the value of the outer diameter d12 of the port barb valley is selected to be the same as the inner diameter value of the circulating pipe hose to be connected, and thus the value of the outer diameter d13 of the first sub-port 311 barb peak determines the barb height.

[0091] Figure 5 is a common embodiment of the connection of a rigid flow distributor / collector and a pipe hose. As shown, Figure 5 The barb height of the first main port 301 cooperates with the wall thickness of the third main pipe hose 33 to determine the liquid tightness at the connection of the first main port 301 and the third main pipe hose 33, and the barb height of the first sub-port 311 cooperates with the wall thickness of the first circulating pipe hose 25 to determine the liquid tightness at the connection of the first sub-port 311 and the first circulating pipe hose 25.

[0092] As can be seen from Figure 5 It can be seen that due to the existence of a certain wall thickness of the barb port of the flow distributor / collector, the inner diameter of the port is obviously smaller than the inner diameter of the pipe hose inserted therein. When the liquid flow passes through the port of the flow distributor / collector from the pipe hose, due to the reduction of the fluid cross-sectional area, resistance is generated, which affects the liquid flow velocity, thereby affecting the performance of the heat exchange garment. Obviously, the reason for generating resistance is that the inner diameter of the pipe hose does not match the inner diameter of the barb port connected thereto.

[0093] The present application is to solve the problem of inner diameter mismatching when the pipe hose and the flow divider / flow collector barb port are connected. The basic idea is that the flow divider / flow collector adopts rigid structure, compared with the conventional rigid structure flow divider / flow collector, the inner diameter of each barb port is enlarged, and the inner diameter of each barb port is the same as the inner diameter of the pipe hose connected with it. Obviously, the outer diameter of the barb port also needs to be increased accordingly. In this case, the size of the flow divider / flow collector barb port no longer matches the size of the pipe hose cavity to be connected, and cannot be normally inserted. The further solution of the present application is to add a matching device between the two, namely a flexible sleeve, one end of the flexible sleeve is sleeved with the pipe hose, and the other end is inserted with the corresponding flow divider / flow collector barb port. In another aspect, after the pipe hose end is sleeved with the flexible sleeve, the inner diameter of the pipe hose end is enlarged, so that the barb port of the flow divider / flow collector with increased outer diameter can be inserted therein. As can be seen, after enlarging the inner diameter of the barb port and adding the flexible sleeve, when the liquid flows from the pipe hose through the flow divider / flow collector barb port, there is no resistance caused by the reduction of fluid cross-sectional area.

[0094] The matching device flexible sleeve is compatible in material with the pipe hose to be connected, and the inner diameter is the same as the outer diameter of the pipe hose to be connected; the end of the pipe hose is placed in the cavity of one end of the flexible sleeve and is tightly sleeved together; the outer diameter of the flow divider / flow collector barb port is slightly larger than the inner diameter of the flexible sleeve, and this "slightly larger" amount is the interference amount, so that the flexible sleeve after insertion generates a radial compression force on the barb port, and the flexible sleeve and the barb port are engaged. The radial compression force makes the inner wall of the flexible sleeve tightly fit on the conical surface of the barb port, forming an initial seal; the barb engagement forms a mechanical lock to prevent the flexible sleeve from being pushed out or loosened under the pressure of the liquid in the pipe or the external pulling force. The thicker the wall thickness of the flexible sleeve, the greater the radial compression force. Since the hose needs to be formed by a mold, the outer diameters of the series of finished pipe materials on the market are usually different by 1 mm, and the corresponding wall thicknesses are different by 0.5 mm; for example, a PVC hose with an inner diameter of 4 mm, the common outer diameter types are 5 mm, 6 mm and 7 mm, and the corresponding wall thicknesses are 0.5 mm, 1 mm and 1.5 mm respectively; if necessary, a mold can be customized to produce a hose product with any wall thickness; usually, the performance difference of the hose is not obvious when the wall thickness difference is very small, and the wall thickness classification does not need to be very fine in actual engineering, and the wall thickness difference of 0.1 mm is very fine.

[0095] The wall thickness of the flexible sleeve is usually the same as the wall thickness of the pipe hose to be connected, or the wall thickness of the standard pipe material close to the wall thickness of the pipe hose, that is, wherein, is the wall thickness of the flexible sleeve, the wall thickness of the flexible sleeve, the wall thickness of the standard pipe material close to the wall thickness of the flexible sleeve; when the liquid tightness and the bite force at the barbed port connection of the flexible sleeve are not enough, or when the hardness of the flexible sleeve is reduced and the radial compression force and the bite force of the flexible sleeve need to be maintained, the wall thickness of the flexible sleeve is increased; for the standard pipe material, the wall thickness of the flexible sleeve is preferably increased by 0.5 mm each time, i.e. , wherein, is the wall thickness adjustment coefficient, ; for the non-standard pipe material, the wall thickness is increased to a predetermined value, i.e. , wherein, is the wall thickness increase value, .

[0096] In one embodiment, the liquid circulating pipe hose is a standard PVC hose with an inner diameter of 2 mm, an outer diameter of 4 mm, and a Shore A hardness of 60, and the wall thickness is 1 mm; the flexible sleeve usually connected therewith is a standard PVC hose with an inner diameter of 4 mm, an outer diameter of 6 mm, and a Shore A hardness of 60, and the wall thickness is also 1 mm, i.e. , the flexible sleeve has the same wall thickness, the same material, and the same material hardness as the pipe hose, and the inner diameter of the flexible sleeve is the same as the outer diameter of the pipe hose. In another embodiment, all parameters of the liquid circulating pipe hose remain unchanged, and the liquid tightness and the bite force at the barbed port connection of the flexible sleeve need to be improved by increasing the wall thickness of the flexible sleeve by 0.5 mm, and the flexible sleeve is a standard PVC hose with an inner diameter of 4 mm, an outer diameter of 7 mm, and a Shore A hardness of 60, and the wall thickness is 1.5 mm, i.e. , , obviously is 0.5 mm more than ; at this time, the flexible sleeve has the same material and the same material hardness as the pipe hose, but the wall thickness is not the same, and the inner diameter of the flexible sleeve is the same as the outer diameter of the pipe hose.

[0097] In another embodiment, the liquid circulating pipe hose is also a standard PVC hose with an inner diameter of 2 mm, an outer diameter of 4 mm, and a Shore A hardness of 60, and the wall thickness is 1 mm; the flexible sleeve usually connected therewith should be a standard PVC hose with an inner diameter of 4 mm, an outer diameter of 6 mm, and a Shore A hardness of 60, and the wall thickness is 1 mm, i.e. Although the flexible sleeve with these parameters can meet the requirements for liquid tightness and interlocking force at the barbed end connection, its flexibility at the connection with the pipe hose is not ideal. Therefore, the hardness of the flexible sleeve was reduced to Shore A hardness 50. To compensate for the decrease in radial compressive force at the barbed end caused by the reduced hardness, the wall thickness of the flexible sleeve was increased. It increased by 0.5 mm, that is , The final selected flexible sleeve is a PVC hose with an inner diameter of 4 mm, an outer diameter of 7 mm, and a Shore A hardness of 50. It perfectly meets the requirements for liquid tightness, interlocking force, and flexibility at the barbed end connection.

[0098] In some applications, even if the hardness of the flexible sleeve is reduced within a certain range and its radial compressive force is reduced, the radial compressive force can still maintain the liquid tightness and interlocking force requirements at the barbed end connection. In this case, the wall thickness of the flexible sleeve can remain unchanged.

[0099] In one embodiment, to improve the thermal conductivity of the liquid circulation pipeline hose, the wall thickness was reduced. A PVC hose with an inner diameter of 2.4 mm, an outer diameter of 4 mm, and a Shore A hardness of 60 was selected. It is 0.8 mm; the flexible sleeve that it is usually connected to should be a PVC hose with an inner diameter of 4 mm, an outer diameter of 5.6 mm, a Shore A hardness of 60, and a wall thickness of 0.8 mm. It is also 0.8 mm, that is While flexible sleeves with these parameters can meet the liquid tightness and interlocking force requirements at the barbed end connection, these are non-standard sizes on the market and require customization. Another economical approach is to use standard PVC flexible tubing with dimensions close to these specifications as the flexible sleeve, such as a PVC flexible tubing with an inner diameter of 4 mm, an outer diameter of 6 mm, a Shore A hardness of 60, and a wall thickness of [missing information]. It is 1 mm, that is , Compare With an extra 0.2mm, it can obviously meet the requirements for liquid tightness and interlocking force at the barb port connection very well.

[0100] The present invention will be further described below with reference to specific embodiments.

[0101] like Figure 8As shown, the length of the first flexible sleeve 41 is L1, and the length of the interface between the first flexible sleeve 41 and the second circulation pipe hose 26 is L11. The inner diameter of the first flexible sleeve 41 is the same as the outer diameter of the second circulation pipe hose 26, and the two are tightly fitted together. Their materials are compatible. In one embodiment, the first flexible sleeve 41 and the second circulation pipe hose 26 are both made of PVC material, so a reliable liquid-tight joint can be formed by known methods, including solvent bonding, ultrasonic welding, and radio frequency welding. Typically, the material hardness of the first flexible sleeve 41 is the same as that of the second circulation pipe hose 26, and the wall thickness of the first flexible sleeve 41 is the same as that of the second circulation pipe hose 26, or a standard pipe wall thickness close to the wall thickness value of the hose.

[0102] like Figure 9 As shown, the length of the second flexible sleeve 42 is L2, and the length of the interface between the second flexible sleeve 42 and the fourth main pipe hose 34 is L21. The inner diameter of the second flexible sleeve 42 is the same as the outer diameter of the fourth main pipe hose 34, and the two are tightly fitted together. Their materials are compatible. In one embodiment, the second flexible sleeve 42 and the fourth main pipe hose 34 are both made of PVC material, so a reliable liquid-tight joint can be formed by known methods, including solvent bonding, ultrasonic welding, and radio frequency welding. Typically, the material hardness of the second flexible sleeve 42 is the same as that of the fourth main pipe hose 34, and the wall thickness of the second flexible sleeve 42 is the same as that of the fourth main pipe hose 34, or a standard pipe wall thickness close to the wall thickness of the main pipe hose.

[0103] like Figure 10 As shown, the sixth distributor / collector 600 has one main port and four sub-ports; the main port is the second main port 601, whose inner diameter is the same as the inner diameter of the fourth main pipe hose 34 to which it is connected; the four sub-ports include: the fifth sub-port 611, the sixth sub-port 612, the seventh sub-port 613, and the eighth sub-port 614. The four sub-ports have the same function and size, and their inner diameter is the same as the inner diameter of the second pipe hose 26 to which they are connected. Here, only the fifth sub-port 611 is used as an example to describe its connection process with the second circulation pipe hose 26.

[0104] Bundle Figure 8The first flexible sleeve 41, which is fitted onto the second circulation pipe hose 26, is inserted into the fifth sub-port 611 of the sixth distributor / collector 600. The outer diameter of the fifth sub-port 611 is slightly larger than the inner diameter of the first flexible sleeve 41. The barbed end of the fifth sub-port 611 is located inside the cavity of the first flexible sleeve 41. The interference fit between the two forms a liquid-tight structure. Since the inner diameter of the second circulation pipe hose 26 is the same as the inner diameter of the fifth sub-port 611, when the liquid flows from the second circulation pipe hose 26 through the fifth sub-port 611, there will be no resistance caused by the reduction of the fluid cross-sectional area, thus affecting the liquid flow velocity.

[0105] Similarly, put Figure 9 The second flexible sleeve 42, which is sleeved on the fourth main pipe hose 34, is inserted into the second main port 601 of the sixth distributor / collector 600. The outer diameter of the second main port 601 is slightly larger than the inner diameter of the second flexible sleeve 42. The barbed end of the second main port 601 is located inside the cavity of the second flexible sleeve 42. The interference fit between the two forms a liquid-tight structure. Since the inner diameter of the fourth main pipe hose 34 is the same as the inner diameter of the second main port 601, when the liquid flows from the fourth main pipe hose 34 through the second main port 601, there will be no resistance caused by the reduction of the fluid cross-sectional area, thus affecting the liquid flow velocity.

[0106] Typically, the material hardness of the flexible sleeve is selected to be the same as that of the pipe hose it connects to; or the hardness of the flexible sleeve is reduced to improve flexibility. The material hardness of the flexible sleeve determines its flexibility at the connection with the pipe hose; better flexibility makes it less prone to breakage even after repeated bending; the lower the material hardness, the better the flexibility. If the hardness of the flexible sleeve is reduced, various methods can be used to compensate for the liquid tightness and interlocking force at the barbed end connection. These methods include increasing the wall thickness of the flexible sleeve. Increase the barb height at the barb port. Increase the number of barbs at the barbed port. .

[0107] As mentioned earlier, the wall thickness of the flexible sleeve is typically selected to be the same as the wall thickness of the pipe hose it is mating with, or the wall thickness of a standard pipe material that is close to the wall thickness of the pipe hose. Increasing the wall thickness of the flexible sleeve of the matching device can improve the liquid tightness and interlocking force at its connection with the barbed port. When the hardness of the flexible sleeve decreases, the wall thickness of the flexible sleeve should be increased to maintain its radial compressive force and interlocking force.

[0108] The barb height of the shunt / collector barb port depends on the pipe diameter, wall thickness and hardness of the flexible sleeve connected thereto; for pipe hoses used in heat exchange clothing, pipe materials with moderate hardness are usually selected, and pipes with special hardness are not selected; it is generally considered that the barb height of the barb port should not exceed the wall thickness of the flexible sleeve connected thereto, and the barb height is usually designed to be between 25% and 75% of the wall thickness of the flexible sleeve connected thereto, so as to ensure that the port barb can be reliably engaged with the flexible sleeve, and the flexible sleeve is not pierced or torn by the port barb; the corresponding barb height of the flexible sleeve with small pipe diameter should be taken in the direction of 25% of the lower limit of the wall thickness, and the corresponding barb height of the flexible sleeve with large pipe diameter should be taken in the direction of 75% of the upper limit of the wall thickness; in order to simplify the design, the barb height is taken as the middle value, the barb height of the main port is designed to be 50% of the wall thickness of the flexible sleeve connected to the main port, and the barb height of the sub-port is designed to be 40% of the wall thickness of the flexible sleeve connected to the sub-port. The relationship between the barb height and the wall thickness of the flexible sleeve is: wherein, is the barb height of the barb port, is the wall thickness of the flexible sleeve, is a proportional coefficient, preferably corresponding to the main port, corresponding to the sub-port, the barb height of the barb port can be adjusted according to needs, the adjustment range of .

[0109] The number of barbs of the barb port is determined according to the size of the pipe diameter of the shunt / collector barb port and the length requirement of the port; the number of barbs of the barb port is preferably: the main port has barbs, and the sub-port has barbs; the more the number of barbs of the barb port, the better the liquid tightness and the stronger the engagement force at the connection between the barb port and the flexible sleeve; when the liquid tightness and the engagement force at the connection between the barb port and the flexible sleeve are not enough, the number of barbs of the barb port can be increased to compensate; for example, the decrease of the wall thickness of the flexible sleeve or the decrease of the hardness of the flexible sleeve material can be compensated by increasing one or two barbs of the barb port.

[0110] as Figure 10As shown, since the inner diameter of the fifth sub-port 611 is the same as that of the second circulating pipe hose 26, if the outer diameter of the fifth sub-port 611 at the valley of the barb is the same as that of the second circulating pipe hose 26, the minimum wall thickness of the fifth sub-port 611 is the same as that of the second circulating pipe hose 26, and at this time the outer diameter of the fifth sub-port 611 at the peak of the barb determines the height of the barb of the port; the liquid tightness between the first flexible sleeve 41 and the fifth sub-port 611 is determined by the wall thickness of the first flexible sleeve 41 and the height and number of the barbs of the fifth sub-port 611. Generally, the height of the barb of the fifth sub-port 611 is selected to be 40% of the wall thickness of the first flexible sleeve 41, and the number of the barbs is 1; for special requirements, the wall thickness of the first flexible sleeve 41 and the height and number of the barbs of the fifth sub-port 611 can be further adjusted to meet the condition that the first flexible sleeve 41 is not pushed out or loosened from the fifth sub-port 611 under the action of a specific internal liquid pressure or a specific external pulling force.

[0111] Similarly, since the inner diameter of the second main port 601 is the same as that of the fourth main pipe hose 34, if the outer diameter of the second main port 601 at the valley of the barb is the same as that of the fourth main pipe hose 34, the minimum wall thickness of the second main port 601 is the same as that of the fourth main pipe hose 34, and at this time the outer diameter of the second main port 601 at the peak of the barb determines the height of the barb of the port; the liquid tightness between the second flexible sleeve 42 and the second main port 601 is determined by the wall thickness of the second flexible sleeve 42 and the height and number of the barbs of the second main port 601; generally, the height of the barb of the second main port 601 is selected to be 50% of the wall thickness of the second flexible sleeve 42, and the number of the barbs is 3. For special requirements, the wall thickness of the second flexible sleeve 42 and the height and number of the barbs of the second main port 601 can be further adjusted to meet the condition that the second flexible sleeve 42 is not pushed out or loosened from the second main port 601 under the action of a specific internal liquid pressure or a specific external pulling force.

[0112] The barb spacing of the barb port is reasonably selected to disperse stress while ensuring continuous engagement, and generally the barb spacing is designed to be about 3.8 mm, and generally the barb spacing rarely exceeds 8 mm; according to needs, the barb spacing of the barb port can be adjusted; in the case that the port length of the barb port is limited and the number of the barbs of the barb port cannot be reduced, the barb spacing of the barb port can be reduced to achieve it, and generally the wall thickness value of the flexible sleeve connected thereto is taken as the minimum limit value of the barb spacing. Therefore, the barb spacing of the barb port of the flow divider and the flow collector is: , and the preferred value is 3.8 mm; wherein, is the barb spacing, is the wall thickness value of the flexible sleeve.

[0113] As mentioned before, the minimum wall thickness of the barb port is usually selected to be the same as the wall thickness of the pipe hose it is connected to; when the wall thickness of the pipe hose is thin, if the minimum wall thickness of the corresponding barb port cannot meet the mechanical strength requirement, the minimum wall thickness of the barb port at the barb valley needs to be increased by increasing the outer diameter of the barb port at the barb valley to increase the minimum wall thickness of the barb port at the barb valley to improve the mechanical strength of the barb port at the minimum wall thickness, to meet , and (usually the increment of the minimum wall thickness of the barb port should not exceed the barb height of the port it is in), wherein, is the wall thickness of the pipe hose, is the increment of the wall thickness, is the barb height.

[0114] As shown in Figure 10 , the length of the first flexible sleeve 41 is L1, the length of the interface between the first flexible sleeve 41 and the second circulating pipe hose 26 is L11, the distance between the end face of the second circulating pipe hose 26 and the end face of the fifth sub-port 611 is L12, and the length of the interface between the fifth sub-port 611 and the first flexible sleeve 41 is L13.

[0115] As can be seen from Figure 10 , the value of the length L1 of the first flexible sleeve 41 is determined by the three length values of L11, L12 and L13.

[0116] The minimum length of L11 is related to the sealing process used, which includes solvent bonding, ultrasonic welding and radio frequency welding as mentioned before.

[0117] The minimum value of L12 can be zero, and when it is not zero, a bridge can be formed by the first flexible sleeve 41, and the L12 is the gap value of the bridge.

[0118] The maximum value of L13 is the length of the first sub-port 611, which at least includes a port barb.

[0119] The length of the second flexible sleeve 42 is L2, the length of the interface between the second flexible sleeve 42 and the fourth main pipe hose 34 is L21, the distance between the end face of the fourth main pipe hose 34 and the end face of the second main port 601 is L22, and the length of the interface between the second main port 601 and the second flexible sleeve 42 is L23.

[0120] Similarly, the value of the length L2 of the second flexible sleeve 42 is determined by the three length values of L21, L22 and L23. The influencing factors of the values of L21, L22 and L23 are the same as those of the values of L11, L12 and L13, and will not be described again.

[0121] The length of the flexible sleeve wherein, is the port length of the shunt and the hub barb port to be interfaced with, is the bridging gap between the barb port end side and the conduit hose end side, is the sleeve length between the flexible sleeve and the conduit hose.

[0122] The principle of the present invention is to construct the flexible sleeve and the shunt / hub barb port under the premise of known conduit hose inner diameter, outer diameter and material quality, so that there is no reduction in fluid cross-sectional area when the fluid flows from the conduit hose through the port of the shunt / hub. The construction and matching method includes the following steps:

[0133] (c) Determining the wall thickness of the flexible sleeve: The wall thickness of the flexible sleeve , wherein, is the wall thickness of the pipeline hose that interfaces with the flexible sleeve, is the wall thickness of the standard pipe material close to the wall thickness of the pipeline hose; when the liquid tightness and bite force at the connection of the barb port of the flexible sleeve are not enough, or when the hardness of the flexible sleeve needs to be reduced to maintain its radial compression force and bite force, increase the wall thickness of the flexible sleeve: for standard pipe materials, preferably increase the wall thickness of the flexible sleeve by 0.5 mm each time, i.e. , wherein, is the wall thickness adjustment coefficient, ; for non-standard pipe materials, the wall thickness is increased to a predetermined value, i.e. , wherein, is the wall thickness increase value, ;

[0134] (d) Determining the hardness of the flexible sleeve material: The hardness of the flexible sleeve is the same as the hardness of the pipeline hose that interfaces with it, or the hardness of the flexible sleeve is reduced to improve flexibility; if the hardness of the flexible sleeve is reduced, compensate for its liquid tightness and bite force at the connection of the barb port by increasing the wall thickness of the flexible sleeve , increasing the barb height of the barb port , and increasing the number of barbs of the barb port ;

[0141] The flexible sleeve and the barb port of the shunt and the collector are matched as described in steps S10 and S20. The matching of the flexible sleeve and the barb port of the shunt and the collector needs to be considered comprehensively from the aspects of cost, space occupation, liquid tightness, bite force, flexibility, etc. The wall thickness, hardness and length of the flexible sleeve and the height, number and spacing of the barbs of the barb port are optimized to meet the requirements of size, liquid tightness, bite force and flexibility at the connection between the flexible sleeve and the barb port. Steps S10 and S20 are not in a certain order. The wall thickness, hardness and length of the flexible sleeve and the height, number and spacing of the barbs of the barb port are changed repeatedly until the matching device flexible sleeve with the required inner diameter, outer diameter, length, material and hardness and the port with the required inner diameter, number of barbs, spacing of barbs, outer diameter at the valley of the barb and outer diameter at the peak of the barb are obtained.

[0142] As described above, the inner diameter of the barb port of the shunt and the collector is required to be the same as the inner diameter of the pipeline hose connected thereto. However, there is an error in engineering. As long as the inner diameters of the two are close, they are connected together by the flexible sleeve and belong to the protection scope of the present application. Even if the resistance to the liquid flow at the port connection is not completely eliminated, it is minimized. Similarly, the two corresponding sizes are required to be the same in many other places of the present application.

[0143] In an embodiment, only part of the ports of the shunt and the collector are connected to the corresponding pipeline hose by using the sleeve connection technology of the present application, and the connection of the remaining ports is performed by using the conventional technology. For example, the connection between the main pipeline hose with a relatively large diameter and the main port is performed by using the common direct plug-in method, and the connection between the circulating pipeline hose and the sub-port is performed by using the sleeve connection technology of the present application. As long as one port adopts the sleeve connection technology of the present application, it belongs to the protection scope of the present application.

[0144] In an embodiment, in order to further enhance the liquid tightness at the connection between the flexible sleeve and the barb port and prevent the sleeve from falling off, the flexible sleeve is locked on the port by using a strap, which still belongs to the protection scope of the present application.

[0145] In an embodiment, in order to further enhance the liquid tightness at the connection between the flexible sleeve and the barb port and prevent the sleeve from falling off, an adhesive is applied to the interface between the outside of the port and the inside of the flexible sleeve, and the two are bonded together, which also belongs to the protection scope of the present application.

[0146] The shunt / collector described in the embodiments herein is a main port and four sub-ports, which is only for the convenience of description and is not a limitation of the present application, and the present application is applicable to any number of ports of the shunt / collector; the present application solves the problem of matching the inner diameter of the barbed port with the inner diameter of the pipeline hose, and is applicable to any shape structure of the shunt / collector.

[0147] The technical principles of the present application are described above in combination with specific embodiments, and these descriptions are only for explaining the principles of the present application, and cannot be explained as a limitation on the protection scope of the present application in any way. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative labor, and these embodiments will fall within the protection scope of the present application.

[0148] The steps in the present application are arranged by using labels, but are not used to limit the sequence of the steps, unless the sequence of the steps is explicitly described or the execution of a certain step needs other steps as a basis, otherwise the relative sequence of the steps can be adjusted. It can be understood that the term “and / or” used herein involves and covers any and all possible combinations of one or more of the associated listed items.

[0149] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in any way, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
