Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger-related equipment, and more specifically to a cavity heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] Meanwhile, existing heat exchangers are generally composed of heat exchange tubes and fins. The heat exchange tubes consist of multiple horizontal rods, with U-shaped bends welded between adjacent horizontal rods to form an S-shaped heat exchange tube. During processing, it is necessary to ensure that each U-shaped bend is welded to the corresponding two horizontal rods. Each heat exchanger requires a large number of U-shaped bends for installation and connection, resulting in a large number of parts to be processed, making welding and manufacturing difficult. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cavity heat exchanger. It connects two corresponding heat exchange tubes by forming corresponding liquid-passing grooves on the left connecting plate at the end of the laterally extending straight heat exchange tubes, thereby realizing the connection between the two corresponding heat exchange tubes. This eliminates the need for welding U-shaped connectors for connection, greatly reducing the number of U-shaped connectors, reducing the number of processed parts, and making processing and manufacturing convenient.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A cavity heat exchanger includes heat exchange tubes and multiple heat exchange fins. All heat exchange tubes are inserted into corresponding mounting holes in all heat exchange fins. The left ends of all heat exchange tubes are fixed to the same left vertical plate and communicate with corresponding through holes on the left vertical plate. A vertical plate body of a left connecting plate is welded to the left side wall of the left vertical plate. Multiple left-extending protrusions are formed on the left side wall of the vertical plate body of the left connecting plate. The interior of the protrusions is a liquid-passing groove. The right side wall of the liquid-passing groove extends out of the right side wall of the vertical plate of the left connecting plate and communicates with the corresponding through holes.

[0007] The protrusion is waist-shaped, and each liquid-passing groove communicates with two corresponding through holes.

[0008] Multiple heat exchange tubes are arranged in a vertical heat exchange tube group, and all heat exchange tubes are arranged in two vertical columns corresponding to each other.

[0009] The left ends of the two heat exchange tubes corresponding to each other in the two rows of heat exchange tubes are connected to the same liquid passage groove.

[0010] The inner wall of all the through holes on the left vertical plate is formed with a connecting extension sleeve that extends to the left. The left end of the heat exchange tube is inserted into the corresponding connecting extension sleeve, and the outer wall of the left end of the heat exchange tube is welded and fixed to the inner wall of the corresponding connecting extension sleeve.

[0011] All heat exchange tubes are fixed to the same right vertical plate at their right ends and communicate with the corresponding right through hole on the right vertical plate. The right connecting plate is welded to the right side wall of the right vertical plate. Two vertically extending protrusions extending to the right are formed on the right side wall of the right connecting plate. The interior of the vertically extending protrusions is a vertical liquid-passing groove. The left end of the vertical liquid-passing groove extends out of the left side wall of the right connecting plate and communicates with the corresponding right through hole in the same vertical column.

[0012] A feed through hole is formed on the outer wall of the middle part of a vertically extending protrusion, and the feed through hole communicates with the corresponding vertical liquid passage groove. A discharge through hole is formed on the outer wall of another vertically extending protrusion, and the discharge through hole communicates with the corresponding vertical liquid passage groove.

[0013] The outstanding effect of this utility model is:

[0014] Compared with existing technologies, it connects two corresponding heat exchange tubes by forming corresponding liquid-passing grooves on the left connecting plate at the end of the laterally extending straight heat exchange tube, thereby achieving the connection between the two corresponding heat exchange tubes. This eliminates the need for welding U-shaped connectors for connection, greatly reducing the number of U-shaped connectors, reducing the number of processed parts, and making processing and manufacturing easier.

[0015] Meanwhile, the fluid-passing groove on its left connecting plate can be formed by one-time stamping, which greatly reduces the processing difficulty, makes processing more convenient, and reduces manufacturing costs. Attached Figure Description

[0024] For example, see below. Figures 1 to 8 As shown, a cavity heat exchanger includes heat exchange tubes 10 and multiple heat exchange fins 20, all of which are straight tubes extending laterally.

[0025] All heat exchange tubes 10 are inserted into the corresponding mounting holes of all heat exchange fins 20. The left ends of all heat exchange tubes 10 are fixed to the same left vertical plate 30 and communicate with the corresponding through holes 31 on the left vertical plate 30. The left vertical plate body of the left connecting plate 40 is welded and fixed to the left side wall of the left vertical plate 30. Multiple protrusions 41 extending to the left are formed on the left side wall of the left connecting plate 40. The inside of the protrusions 41 is a liquid-passing groove 42. The right side wall of the liquid-passing groove 42 extends out of the right side wall of the left connecting plate 40 and communicates with the corresponding through holes 31.

[0026] Furthermore, the protrusion 41 is waist-shaped, and each fluid-passing groove 42 communicates with the corresponding two through holes 31. In this embodiment, the protrusion 61 is a waist-shaped protrusion extending obliquely. All protrusions 61 are arranged vertically and parallel to each other. The side plate of the protrusion 41 is arc-shaped, which is formed by stamping the vertical plate of the left connecting plate 40 in one go, forming multiple protrusions 41 extending to the left with internal cavities. These cavities are the fluid-passing grooves 42. The one-time stamping process makes it easy to manufacture, greatly reduces the processing difficulty, eliminates the need for U-shaped connectors, saves materials and costs, reduces processing difficulty, and improves production efficiency.

[0027] Furthermore, in this embodiment, half of the heat exchange tubes 10 are arranged in a vertical heat exchange tube group, and all the heat exchange tubes 10 are arranged in two vertical columns of heat exchange tube groups that are corresponding to each other. The two columns of heat exchange tube groups are corresponding to each other, and the left end of each pair of corresponding heat exchange tubes 10 is connected to the same liquid passage groove 42.

[0028] Furthermore, the left connecting plate 40 has a bent connecting edge extending to the left formed on the front or rear side of its vertical plate body. The bent connecting edge is used for fixing and connecting to the position where it needs to be installed.

[0029] Furthermore, all the through holes 31 on the left vertical plate 30 have a left-extending connecting extension sleeve 32 formed on their inner sidewalls. The left end of the heat exchange tube 10 is inserted into the corresponding connecting extension sleeve 32, and the outer sidewall of the left end of the heat exchange tube 10 is welded and fixed to the inner sidewall of the corresponding connecting extension sleeve 32.

[0030] Furthermore, the right end of all heat exchange tubes 10 is fixed to the same right vertical plate 50 and communicates with the corresponding right through hole 51 on the right vertical plate 50. The right vertical plate body of the right connecting plate 60 is welded and fixed to the right side wall of the right vertical plate 50. Two vertically extending protrusions 61 extending to the right are formed on the right side wall of the vertical plate body of the right connecting plate 60. The interior of the vertically extending protrusions 61 is a vertical liquid passage groove 62. The left end of the vertical liquid passage groove 62 extends out of the left side wall of the vertical plate body of the right connecting plate 60 and communicates with the corresponding right through hole 51 in the same vertical column.

[0031] The vertical plate of the right connecting plate 60 is formed by one stamping, forming two vertically extending protrusions 61 with vertical cavities inside, which are corresponding to each other. These vertical cavities are vertical liquid passage grooves 62. The one-time stamping makes it easy to manufacture, greatly reduces the processing difficulty, and eliminates the need to weld other liquid collection components, saving materials and costs, reducing processing difficulty and improving production efficiency.

[0032] Furthermore, a feed through hole 63 is formed on the outer wall of the middle part of a vertically extending protrusion 61, and the feed through hole 63 communicates with the corresponding vertical liquid passage groove 62. A discharge through hole 64 is formed on the outer wall of the upper part of another vertically extending protrusion 61, and the discharge through hole 64 communicates with the corresponding vertical liquid passage groove 62.

[0033] Furthermore, the right connecting plate 60 has a rightwardly extending bent connecting edge formed on the front or rear right side of its vertical plate body. The bent connecting edge is used for fixing and connecting to the required installation position.

[0034] Furthermore, all the through holes 51 on the right vertical plate 50 have right connecting extension sleeves 52 formed on their inner walls, extending to the right. An annular groove is formed on the inner wall of the left end of the right connecting extension sleeve 52. The right end of the heat exchange tube 10 is inserted into the corresponding right connecting extension sleeve 52. A radially extending positioning protrusion ring 11 is formed on the outer wall of the left part of the right end of the heat exchange tube 10. The positioning protrusion ring 11 is inserted into the annular groove, with its right end face pressing against the right end face of the annular groove. Its outer wall is in contact with or tightly attached to the inner wall of the annular groove. The outer wall of the right end of the heat exchange tube 10 is welded and fixed to the inner wall of the right connecting extension sleeve 52. The right end face and outer wall of the positioning protrusion ring 11 are welded and fixed to the right end face and inner wall of the corresponding annular groove. This positioning protrusion 11 has a positioning effect when the heat exchange tube 10 is connected and fixed to the right vertical plate 50. At the same time, it extends into the corresponding annular groove to connect, increasing the support strength of the connection between the heat exchange tube 10 and the right vertical plate 50 and improving the connection firmness.

[0035] This embodiment omits the U-shaped connector and instead forms a protrusion 41 on the left side wall of the vertical plate of the left connecting plate 40 through a single stamping process. A vertically extending protrusion 61 is formed on the right connecting plate 50 through a single stamping process. All heat exchange tubes 10 are connected through the protrusion 41 and the vertically extending protrusion 61. This process is fast, the difficulty is reduced, the number of parts is greatly reduced, the processing efficiency is improved, and the manufacturing cost is reduced.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
