Description

Technical Field

[0001] The utility model relates to the technical field of thermal management and heat exchangers, in particular to a modular heat exchanger based on a skeleton. Background Art

[0002] Heat transfer technology is widely used in various fields, and the common heat transfer technology needs are mainly heat exchangers and thermal management devices. Modular heat exchangers are based on the modular principle and are formed by splicing several integrated heat exchange units. They can improve the heat transfer coefficient while reducing the cost and manufacturing difficulty of the heat exchanger, and have considerable development potential. The existing skeleton modular heat exchanger has a splicing structure of a transverse structure and a longitudinal structure. Considering that the current processing level is not enough to produce these structures at low cost and in large quantities, it is difficult to reduce the cost of modular heat exchangers at the current stage, making it difficult to directly put them into engineering applications. At the same time, the existing technology of spliced ​​heat exchanger tube sheets, that is, splicing tube sheet splicing units containing tube holes to directly form the tube sheet of a shell and tube heat exchanger, is essentially still an ordinary shell and tube heat exchanger tube sheet manufacturing method, which requires high assembly accuracy and still cannot solve the difficulty and cost of inserting capillary heat exchangers with a large number and high pressure resistance. Utility Model Content

[0003] The purpose of the utility model is to provide a modular heat exchanger based on a skeleton, which can meet the needs of simulating micro-drilling tests with different well inclination angles. By proposing the concept and structure of a skeleton, the heat exchange unit is horizontally spliced ​​to achieve modular functions. The skeleton of this solution is based on a modular capillary heat exchanger, in which the tube sheets of the assembled heat exchange unit are attached to the skeleton to provide sealing, pressure-bearing and connection functions to solve the problems raised in the above-mentioned background technology.

[0005] Preferably, the heat exchanger skeleton and the heat exchanger tube sheet are connected by welding.

[0006] Preferably, the heat exchanger tube sheet is made of metal materials such as copper, stainless steel, high-temperature alloy steel, nickel alloy, and titanium alloy.

[0007] Preferably, the tube sheet assembly holes inside the heat exchanger skeleton are arranged according to a certain pattern.

[0008] Preferably, the diameter of the heat exchanger skeleton is determined by the modular arrangement requirements of the tube sheet assembly holes.

[0009] Preferably, tube holes are provided inside the tube sheet of the heat exchanger.

The modular heat exchanger based on the skeleton realizes the modularization of the heat exchanger based on the skeleton, comprehensively considers the manufacturing cost and the high-pressure bearing requirements, and realizes the construction of the modular heat exchanger by connecting the tube sheet of the heat exchange unit with the skeleton, which has strong versatility and feasibility.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3The utility model provides a technical solution: a modular heat exchanger based on a skeleton, comprising: a heat exchanger skeleton 101 and a heat exchanger tube sheet 102 spliced ​​therewith, the heat exchanger skeleton 101 and the heat exchanger tube sheet 102 are welded together, the heat exchanger tube sheet 102 is made of metal materials such as copper, stainless steel, high-temperature alloy steel, nickel alloy, titanium alloy, etc., the interior of the heat exchanger skeleton 101 is provided with a chamfered regular hexagonal tube sheet assembly hole, the fillet after chamfering can avoid the phenomenon of stress concentration, and the heat exchanger tube sheet 102 is placed in the tube sheet assembly hole.

[0021] The tube sheet assembly holes inside the heat exchanger skeleton 101 are arranged according to a certain pattern.

[0022] The diameter of the heat exchanger skeleton 101 is determined by the modular arrangement requirements of the tube sheet assembly holes. The modular arrangement can keep the heat exchanger skeleton 101 under maximum stress.

[0023] The heat exchanger tube sheet 102 is provided with tube holes inside, through which micro-pipes can be inserted. Usually, the diameter of the tube holes is between 0.3 and 3 mm, and the distance between the tube holes is maintained at 0.5 to 5 mm.

[0024] Example 2: Reference Figure 1-3 In this embodiment, the transverse splicing of 7 heat exchange units is taken as an example. The end plate of the entire heat exchanger is formed by splicing the heat exchanger skeleton 101 and the heat exchanger tube sheets 102 of the 7 heat exchange units to form a circular end plate. The tube sheets of the heat exchange units and the heat exchanger skeleton 101 are welded to form a whole. When modularizing the heat exchanger, since heat exchangers with different cylinder diameters have different requirements for the thickness of the end plates, when only one thickness of end plates is made, when splicing heat exchangers with smaller heat exchange areas and splicing heat exchangers with larger heat exchange areas, the thickness of the end plates will definitely not meet the pressure requirements. In order to better modularize, this embodiment proposes the concept of a skeleton, that is, the tube sheets of the heat exchange units are all processed into a consistent size that meets the minimum requirements, and then skeletons of different thicknesses are processed according to the cylinder diameter of the modular heat exchanger to meet the pressure requirements of the heat exchanger end plates, and the heat exchange units are expanded horizontally at the same time. In this way, the pressure requirements of the heat exchanger can be met by the skeleton, and the heat exchange can be met by the heat exchange unit, so that the modular heat exchanger can be quickly assembled.

[0025] Example 3: Reference Figure 4 In this embodiment, modular heat exchange units are connected by a skeleton structure to form a modular heat exchanger. Considering that most tube sheets of engineering shell and tube heat exchangers are circular, the heat exchanger skeleton 101 in Embodiments 1 and 2 is circular. In fact, skeletons of different shapes can be designed according to needs. This embodiment is a rectangular skeleton. The advantage of a rectangular skeleton is that it is highly splicable. The same product can be stacked. When in use, the semi-cylindrical head can be welded to achieve heat exchanger sealing and pipe-pass medium.

[0026] Example 4: Reference Figure 5 The present embodiment is a hexagonal frame, which has the advantage of being compatible with the structure of a modular capillary heat exchanger and improving its compactness.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
