Description

Technical Field

[0001] This utility model is a heat exchanger head, belonging to the field of heat exchangers. Background Technology

[0002] The heat exchanger head is a key component of a heat exchanger, located at the end of the equipment, primarily serving a sealing and connecting function. Elliptical heads are one of the most common types of heat exchanger heads. Composed of a semi-ellipse and straight edges, elliptical heads are widely used in medium- and high-pressure heat exchangers due to their excellent load-bearing capacity and ability to withstand high pressures. In heat exchangers and other equipment, baffles are welded inside the elliptical head to separate the internal space, allowing the medium to flow through two independent spaces within the head. Due to its unique structure, the elliptical head has a considerable depth. While this feature contributes to performance optimization in some aspects, it also presents challenges for the installation of the internal baffles.

[0003] When it is necessary to fix the partition plate to the inside of an elliptical head by welding, the relatively small internal space of the head provides very limited space for welding operations. In such a confined environment, welders find it difficult to flexibly use welding tools and techniques, increasing the difficulty of precisely controlling the welding angle and position. Furthermore, the limited space results in poor ventilation during the welding process, making it difficult to quickly expel welding fumes and exhaust gases, which not only affects the welder's vision but may also pose a health hazard. In addition, welding in a confined space places special demands on the size and flexibility of the welding equipment; conventional welding equipment may not meet the operational requirements, further increasing the difficulty of welding and presenting the entire welding process with numerous technical challenges. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat exchanger head to solve the problems mentioned in the background art. This utility model avoids the complicated operation of welding baffles inside the narrow head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger end cap, comprising a cylindrical body, a removable plug installed at one end of the cylindrical body, a baffle welded inside the plug, the end of the baffle away from the plug extending into the cylindrical body, an inlet pipe and an outlet pipe symmetrically arranged about the baffle installed on the outer surface of the cylindrical body, two symmetrically arranged U-shaped frames installed on each of the two parallel sides of the baffle, a support strip installed at the end of the U-shaped frame away from the baffle, a sealing strip installed on the side of the support strip away from the center area of ​​the baffle, four insertion grooves that mate with the sealing strips being opened on the inner wall of the cylindrical body, the end of the sealing strip away from the support strip being inserted into the insertion groove, the sealing strip being tightly fitted to the inner wall of the insertion groove, and the length of the U-shaped frame being the same as the length of the insertion groove.

[0006] Furthermore, a first connecting ring is fitted onto one end of the cylinder near the plug and is fixed to the cylinder. A second connecting ring is provided on one side of the first connecting ring to cooperate with the first connecting ring. The second connecting ring is fitted onto the plug and is fixed to the plug. The first connecting ring is connected to the second connecting ring by fasteners formed by multiple sets of screws and nuts.

[0007] Furthermore, a sealing ring is provided between the cylinder and the plug, the sealing ring is located between the first connecting ring and the second connecting ring, and one end of the screw passes through the sealing ring.

[0008] Furthermore, the side of the sealing strip away from the support strip is a first arc-shaped surface, and the side of the insertion groove facing the support strip is a second arc-shaped surface, with the first arc-shaped surface and the second arc-shaped surface fitting together.

[0009] Furthermore, a flange ring is fitted onto the end of the cylinder away from the plug, and the flange ring has multiple circular holes equidistantly spaced on one side.

[0010] Furthermore, a raised ring is installed on the side of the flange facing the plug, and the raised ring is sleeved on the cylinder and connected and fixed to the cylinder.

[0011] Furthermore, a first flange is installed at the end of the inlet pipe that is away from the cylinder, and a second flange is installed at the end of the outlet pipe that is away from the cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. A removable plug is installed at one end of the cylinder to avoid the complicated operation of welding baffles inside the confined head. The baffles are pre-welded to the plug, and then the plug is installed on the cylinder, which greatly reduces the installation difficulty, facilitates welding operations, and makes it easier to inspect and replace the baffles or other internal components of the head, reducing maintenance costs and time.

[0014] 2. The U-shaped frame, support strip and sealing strip on the side of the partition plate are matched with the insertion groove on the inner wall of the cylinder, and the first arc surface of the sealing strip is closely fitted with the second arc surface of the insertion groove, which can effectively prevent the medium from leaking between the two independent spaces, ensure that the medium flows in the two independent spaces in the head according to the design path, and improve the working efficiency and stability of the heat exchanger.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-4This utility model provides a technical solution: a heat exchanger end cap, including a cylinder 1, a detachable plug 12 installed at one end of the cylinder 1, a first connecting ring 11 fitted and fixed to the cylinder 1 at the end of the cylinder 1 near the plug 12, a second connecting ring 13 provided on one side of the first connecting ring 11 to cooperate with the first connecting ring 11, the second connecting ring 13 fitted on the plug 12 and fixed to the plug 12, the first connecting ring 11 being connected to the second connecting ring 13 by fasteners formed by multiple sets of screws and nuts, a sealing ring 14 being provided between the cylinder 1 and the plug 12, the sealing ring 14 being located between the first connecting ring 11 and the second connecting ring 13, one end of a screw passing through the sealing ring 14, the first connecting ring 11 at the end of the cylinder 1 near the plug 12 and the second connecting ring 13 on the plug 12 being connected by screws and nuts, the connection method is simple and reliable, easy to disassemble and install, and the sealing ring 14 improves the sealing performance between the plug 12 and the cylinder 1.

[0023] See Figures 1-3 The outer surface of the cylinder 1 is equipped with an inlet pipe head 10 and an outlet pipe head 2 symmetrically arranged about the partition plate 5. The end of the inlet pipe head 10 away from the cylinder 1 is equipped with a first flange 9, and the end of the outlet pipe head 2 away from the cylinder 1 is equipped with a second flange 3. The end of the cylinder 1 away from the plug 12 is fitted with a flange ring 4 that is connected and fixed to the cylinder 1. One side of the flange ring 4 has multiple circular holes that are equidistantly spaced in an annular shape. A convex ring 15 is installed on the side of the flange ring 4 facing the plug 12. The convex ring 15 is fitted onto the cylinder 1 and connected and fixed to the cylinder 1. The convex ring 15 increases the connection range between the cylinder 1 and the flange ring 4 and enhances the stability of the connection.

[0024] See Figures 1-4A partition 5 is welded inside the plug 12. The end of the partition 5 away from the plug 12 extends into the cylinder 1. Two symmetrically arranged U-shaped frames 6 are installed on each of the two parallel sides of the partition 5. A support strip 8 is installed on the end of the U-shaped frame 6 away from the partition 5. A sealing strip 7 is installed on the side of the support strip 8 away from the center area of ​​the partition 5. The side of the sealing strip 7 away from the support strip 8 is a first arc-shaped surface. Four insertion slots 16 are formed on the inner wall of the cylinder 1 to mate with the sealing strip 7. The side of the insertion slot 16 facing the support strip 8 is a second arc-shaped surface. After the end of the sealing strip 7 away from the support strip 8 is inserted into the insertion slot 16, the first arc-shaped surface and the second arc-shaped surface fit together, and the sealing strip 7 fits tightly against the inner wall of the insertion slot 16. The length of the U-shaped frame 6 is the same as the length of the insertion slot 16. In actual operation, the operator only needs to weld the partition 5 onto the plug 12 beforehand, and then install the plug 12 into the cylinder 1. This method significantly simplifies the installation process, reduces installation difficulty, and makes welding work easier and more convenient. Furthermore, when it is necessary to inspect or replace the baffle 5 or other components inside the head, there is no need for the difficult operations in confined spaces required by traditional methods; simply removing the plug 12 is sufficient, effectively reducing maintenance costs and time, and significantly improving the efficiency and convenience of equipment maintenance. The U-shaped frame 6 and support strip 8 on the side of the baffle 5 are tightly fitted with the insertion groove 16 on the inner wall of the cylinder 1 through the sealing strip 7, where the first arc-shaped surface of the sealing strip 7 perfectly fits the second arc-shaped surface of the insertion groove 16. This carefully designed structure effectively prevents leakage of the medium between the two independent spaces within the head, ensuring that the medium flows strictly according to the designed path within its respective space. As a result, the heat exchange process inside the heat exchanger is more stable and orderly, reducing heat loss and efficiency reduction caused by medium leakage, thereby improving the working efficiency and operational stability of the heat exchanger and ensuring the continuous and efficient operation of the entire heat exchange system.
