Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange units, in particular to a high-efficiency heat exchange unit. Background Art

[0002] The heat exchanger unit can use the heat exchanger to transfer the high-level thermal energy of the heat medium to the heated medium through the metal surface, so that the temperature of the heat medium is reduced and the temperature of the heated medium is increased, thereby reaching the temperature required by the user. It is generally composed of a heat exchanger, a temperature control valve group, a steam trap group (when the heat medium is steam), a circulation pump, an electric control cabinet, a base, pipes, valves, instruments, etc., and can be equipped with an expansion tank, water treatment equipment, water pump frequency conversion control, temperature control valve, remote communication control, etc., to form a complete heat exchange station. It has the advantages of standardization, modularization, easy installation, high efficiency and energy saving, reliable operation, simple and intuitive operation, etc. It is the preferred high-efficiency and energy-saving product and is suitable for sanitary hot water in residences, offices, factories, mines, hospitals, hotels, schools and other occasions.

[0003] However, the current heat exchanger units are troublesome to transport and assemble during installation and use due to the large number of parts and the large size. In addition, they are generally of fixed structure type. Once assembled, the position of the pipeline cannot be adjusted. Under some special conditions, it will be very troublesome to adjust the pipeline. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] The high-efficiency heat exchange unit includes a pipeline structure, a plate heat exchanger and a positioning frame. The input end of the pipeline of the pipeline structure and the output end of the output pipeline are fixedly connected to the input port and the output port of the plate heat exchanger respectively. The plate heat exchanger is fixedly connected to the frame of the positioning frame.

[0006] An outer rotating ball tube is fixedly connected to the bend of the front horizontal pipe structure. The ball at the end of the outer rotating ball tube is movably connected to the end of the inner rotating ball tube fixed with the ball. The inner rotating ball tube is slidably connected to a telescopic tube inside the end away from the ball. By connecting the outer rotating ball tube and the inner rotating ball tube inside the pipe structure, the rotational connection can be used to adjust the main part of the pipe structure to any angle while ensuring pipeline transportation, so as to meet installation requirements in special circumstances and be more convenient for dealing with narrow installation environments.

[0007] A sealing ring is provided at the front end of the piston-shaped end of the telescopic tube, and an active ball is rolledly connected to the inside of the sealing ring. An auxiliary ball is rolledly connected to the inside of the piston-shaped end of the telescopic tube on the side of the sealing ring away from the end face. By connecting the telescopic tube in the pipeline and connecting the sealing ring, active ball and auxiliary ball to the end of the telescopic tube, the inward retraction form can be promoted to quickly realize the scaling adjustment of the pipeline, which not only reduces the space occupied, but also is more conducive to transportation before installation. The adjustable pipeline structure has a higher fault tolerance rate and is more convenient to deal with some problems caused by the pipeline length during installation and use.

[0008] Furthermore, a spherical sealing ring is provided inside the sphere connecting the outer rotating ball tube and the inner rotating ball tube.

[0009] Furthermore, the telescopic tube is a piston-shaped structure.

[0010] Furthermore, the active balls are distributed in a ring shape along the axis of the telescopic tube 103 in the groove on the side of the sealing ring.

[0011] Furthermore, the inner rotating ball tube can rotate around the outer rotating ball tube in the Z-axis direction.

[0012] Furthermore, the auxiliary balls are distributed in an annular manner along the axis of the telescopic tube 103 on the side surface of the piston end of the telescopic tube.

[0013] Furthermore, the telescopic distance of the telescopic tube is determined by the long straight tube distance of the pipeline structure.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model connects the outer rotating ball tube and the inner rotating ball tube inside the pipeline structure in a rotatable manner. While meeting the pipeline transportation requirements, the main part of the pipeline structure can be adjusted to any angle to meet the installation requirements in special circumstances and is more convenient for dealing with narrow installation environments.

[0016] 2. The utility model connects a telescopic tube in the pipeline and connects a sealing ring, an active ball and an auxiliary ball to the end of the telescopic tube, which can promote the inward retraction and quickly realize the scaling adjustment of the pipeline. It not only reduces the space occupied, but also facilitates transportation before installation. The adjustable pipeline structure has a higher fault tolerance rate and is more convenient for dealing with some problems caused by the pipeline length during installation and use.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] Example 1

[0025] like Figure 1-5 As shown, the high-efficiency heat exchange unit includes a pipeline structure 1, a plate heat exchanger 2 and a positioning frame 3. Before assembly and use, the parts can be arranged according to Figure 1 As shown in the structural diagram, the pipeline structure 1 is pre-assembled. After the assembly is completed, the pipe body of the pipeline structure 1 can be pushed inward to shrink it, reducing the area occupied by the pipeline structure 1. Then, the pre-assembled pipeline structure 1, the plate heat exchanger 2 and the positioning frame 3 can be loaded and transported to the designated location for rapid installation and use.

[0026] The pipeline structure 1 is composed of a temperature control valve group, a steam trap group, a circulation pump, pipelines, valves, instruments, etc. The input end and output end of the pipeline are fixedly connected to the input port and output port of the plate heat exchanger 2 respectively, and are fixedly connected to an outer rotating ball tube 101 with a spherical end at the bend. The ball at the end of the outer rotating ball tube 101 is provided with a transfer ball groove. The end of the inner rotating ball tube 102 fixed with the ball is movably connected to the inside of the ball groove, and a sealing ring is provided at the connection position. The inner rotating ball tube 102 is provided with a slideway larger than the inner diameter of the pipeline structure 1 at the end away from the ball, and the interior of the slideway is slidably connected to the telescopic tube 103.

[0027] To sum up, when using the pipeline structure 1, if a special situation occurs and the pipeline position needs to be adjusted, the pipeline structure 1 can be rotated through the inner rotating ball tube 102, so that it rotates in the Z-axis direction around the outer rotating ball tube 101 until it rotates to the appropriate angle, and then it can be positioned; by connecting the outer rotating ball tube 101 and the inner rotating ball tube 102 inside the pipeline structure 1, the connection can be rotated to meet the pipeline transportation while adjusting the main part of the pipeline structure 1 at any angle to meet the installation requirements in special circumstances, which is more convenient for coping with narrow installation environments.

[0028] Example 2

[0029] like Figure 1-5 As shown, in some embodiments, the telescopic tube 103 is a piston-shaped structure, and the piston end is slidably connected to the inner rotating ball tube 102 or the pipeline of the pipeline structure 1, and a sealing ring 1031 is sleeved at the end of the piston head. A V-shaped groove is formed on the annular surface of the sealing ring 1031, and active balls 1032 distributed annularly along the axis of the telescopic tube 103 are rollingly connected inside the groove. At the piston-shaped end of the telescopic tube 103, on the side away from the end surface of the sealing ring 1031, auxiliary balls 1033 distributed annularly along the axis of the telescopic tube 103 are also rollingly connected.

[0030] To sum up, when the pipeline is to be extended or retracted, the position of the telescopic tube 103 must be found first, and the telescopic tube 103 must be pushed according to the direction of the telescopic tube 103 so that it slides inward along the preset telescopic groove inside the pipeline. During the sliding process, the active balls 1032 and the auxiliary balls 1033 inside the sealing ring 1031 will assist the inward movement of the telescopic tube 103, thereby reducing the friction resistance of the sealing ring 1031. By connecting the telescopic tube 103 in the pipeline and connecting the sealing ring 1031, the active balls 1032 and the auxiliary balls 1033 to the end of the telescopic tube 103, the inward retraction can be promoted to quickly realize the scaling adjustment of the pipeline, which not only reduces the space occupied and is more conducive to transportation before installation, but also the adjustable pipeline structure has a higher fault tolerance rate and is more convenient for dealing with some problems caused by the pipeline length during installation and use.

[0031] like Figure 1-4 As shown, in some embodiments, the telescopic distance of the telescopic tube 103 is determined by the long straight pipe distance of the pipeline structure 1; this setting is to maximize the scaling of the pipeline.

[0032] like Figure 1-4 As shown, in some embodiments, the front horizontal inner rotating ball tube 102 is also movably connected to the telescopic tube 103 in the symmetrical pipe of the pipe structure 1; this arrangement is to enable synchronous telescopic extension and contraction to avoid restrictions between structures.

[0033] How it works

[0034] Before assembling and using, first place the parts according to Figure 1 , the pipe structure 1 is pre-assembled as shown in the structural diagram. After the assembly is completed 1, the position of the telescopic tube 103 can be found, and the telescopic tube 103 can be pushed according to the direction of the telescopic tube 103 so that it slides inward along the preset telescopic groove inside the pipeline. During the sliding process, the active balls 1032 and the auxiliary balls 1033 inside the sealing ring 1031 will assist the inward movement of the telescopic tube 103, reducing the friction resistance of the sealing ring 1031, thereby reducing the area occupied by the pipe structure 1. Then the pre-assembled pipe structure 1, the plate heat exchanger 2 and the positioning frame 3 can be loaded and transported to the designated position for rapid installation and use. When installing and using the pipe structure 1, if special circumstances are encountered and the position of the pipe needs to be adjusted, the pipe structure 1 can be rotated by the inner rotating ball tube 102 so that it rotates in the Z-axis direction around the outer rotating ball tube 101 until it rotates to the appropriate angle, and then it can be positioned.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
