DETAILED DESCRIPTION

[0031] The technical scheme of the utility model will be further illustrated by specific embodiments in combination with the drawings.

[0032] Embodiment one

[0033] As Figures 1-6As shown, the quick heat exchange device provided in the embodiment includes a heat exchange cylinder 1, a water blocking element 2, a first end cover 3 and a second end cover 4. The water blocking element 2 is inserted into the heat exchange cylinder 1. The first end cover 3 is connected to the water blocking element 2 through the first end of the heat exchange cylinder 1. The second end cover 4 is connected to the water blocking element 2 through the last end of the heat exchange cylinder 1. The water blocking element 2 is located between the first end cover 3 and the second end cover 4. Specifically, the heat exchange cylinder in the embodiment is a heating cylinder. The heating wire is wound outside the heat exchange cylinder. The heating wire is simple to set and has low space utilization requirements. Moreover, the heating speed is fast, which is very useful for scenarios that require rapid heating and can improve the heating efficiency. The quick heat exchange device of the embodiment disassembles the original integrated structure into three parts, i.e., the water blocking element, the first end cover and the second end cover. The structural design not only reduces the processing difficulty, but also reduces the processing error and damage risk caused by the complex structure, and improves the production efficiency. At the same time, the functionality of the water blocking element is not affected by the simplification of the structure, and the water flow can still be effectively guided to achieve efficient heat exchange. After disassembling the original integrated structure into three parts, the processing and quality control of each component become more independent and clear. This not only effectively reduces the quality control points in the processing process, improves the yield and consistency of the product, but also makes the processing technology and material selection of each component more flexible and optimized. The above technical solution solves the problem of large processing difficulty and low yield caused by the complex structure of the spiral water blocking element made of ceramic material.

[0034] Specifically, the first end cover 3 is provided with a water inlet 31, the second end cover 4 is provided with a water outlet 41, and the two ends of the water blocking element 2 are respectively provided with an inlet 21 and an outlet 22. The water inlet 31 and the inlet 21 are connected in communication, and the water outlet 41 and the outlet 22 are connected in communication. This design not only simplifies the fluid path and reduces the resistance of the fluid in the device, but also improves the heat exchange efficiency. At the same time, this connection method makes the structure of the device more compact, which is convenient for installation and maintenance. In addition, by accurately controlling the position and size of the inlet and outlet, the flow state of the fluid can be further optimized, the heat exchange effect can be improved, and the device can be ensured to operate stably under various working conditions, so as to meet different heat exchange requirements.

[0035] Preferably, the middle part of the water-blocking piece 2 is provided with a threaded channel 23, and the two ends of the threaded channel 23 are respectively provided with a spiral inlet 24 corresponding to the inlet 21 and a spiral outlet 25 corresponding to the outlet 22. The inlet 21 and the spiral inlet 24 are in communication, and the spiral outlet 25 and the outlet 22 are in communication. The surface side of the threaded channel 23 and the inner side of the heat exchange cylinder 1 form a spiral channel 5 for fluid heat exchange. The design of the threaded channel in the middle part of the water-blocking piece greatly enhances the heat exchange effect. The two ends of the threaded channel are respectively provided with a spiral inlet and a spiral outlet, which are in communication with the inlet and the outlet, forming a spiral channel for fluid heat exchange. This design not only increases the residence time of the fluid inside the device, but also increases the contact area of the fluid with the inner wall of the heat exchange cylinder through spiral flow, thereby improving the heat exchange efficiency. In addition, the design of the threaded channel also causes the fluid to generate vortex and turbulence during flow, further promoting heat transfer and exchange, so that the device has higher heat exchange performance under the same conditions.

[0036] Preferably, the first end cover 3 and / or the second end cover 4 are snap-connected with the water-blocking piece 2. In this embodiment, the first end cover 3 and the second end cover 4 are snap-connected with the water-blocking piece 2, and the snap structures of the first end cover 3 and the second end cover 4 are the same. Taking the first end cover 3 as an example, the first end cover 3 is provided with symmetrical snap convex parts 32, and the corresponding part of the water-blocking piece 2 is provided with an L-shaped snap groove 26 matched with the snap convex parts 32. When connected, the first end cover 3 inserts the snap convex parts 32 into the opening of the snap groove 26, and then rotates to snap the snap convex parts 32 inside the L-shaped snap groove 26. The connection of the second end cover 4 is the same. This snap connection has the advantages of easy installation, quick disassembly, no need for additional tools, etc. Through snap connection, the first end cover and the second end cover can be quickly fixed with the water-blocking piece to form a stable fluid channel. This connection method not only simplifies the installation process and reduces the installation cost, but also facilitates quick disassembly and replacement of parts when needed. In addition, the snap connection also has a certain elasticity, which can adapt to water-blocking pieces of different sizes and shapes to some extent, improving the versatility and flexibility of the device.

[0037] Preferably, the first end cover 3 and the second end cover 4 are provided with a hand holding part 6. The hand holding part of this embodiment is a flat platform-like structure. Through the hand holding part, the user can easily move the device to the desired position and perform installation, disassembly, maintenance and other operations. This design not only makes the device more flexible and convenient during use, but also reduces the operation difficulty and labor intensity. In addition, the hand holding part can also serve as the identification and recognition mark of the device, facilitating quick identification and use by users.

[0038] Preferably, the materials of the water-blocking member 2, the first end cover 3 and the second end cover 4 are ceramic. Ceramic materials have excellent high-temperature resistance, corrosion resistance, high strength and low thermal conductivity, etc. Using ceramic materials to make the water-blocking member, the first end cover and the second end cover can not only improve the high-temperature resistance and corrosion resistance of the device, but also reduce heat loss and energy consumption.

[0039] Preferably, a leakage-preventing sealing ring 7 is arranged between the first end cover 3 and / or the second end cover 4 and the heat exchange cylinder 1. In this embodiment, a leakage-preventing sealing ring 7 is arranged between the first end cover 3 and the heat exchange cylinder 1, and a leakage-preventing sealing ring 7 is also arranged between the second end cover 4 and the heat exchange cylinder 1. By arranging a sealing ring between the first end cover and / or the second end cover and the heat exchange cylinder, a tight sealing structure can be formed to ensure that the fluid does not leak outside the device during flow. This design not only improves the sealing performance and safety of the device, but also reduces maintenance costs and environmental pollution risks. In addition, the sealing ring can also absorb and buffer external pressure and vibration to a certain extent, protecting the internal components of the device from damage.

[0040] Preferably, the material of the sealing ring 7 is silicone rubber. Silicone rubber material has excellent high-temperature resistance and chemical stability, and can maintain stable physical and chemical properties in high-temperature environments without aging or deformation due to long-term high-temperature use. At the same time, silicone rubber material also has good elasticity and sealing performance, which can tightly fit the surface of the first end cover, the second end cover and the heat exchange cylinder, effectively preventing water leakage.
