Description

Technical Field

[0001] The utility model relates to the technical field of fin heat exchangers, in particular to a fin heat exchanger. Background Art

[0002] Finned heat exchanger is the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes. The base tube can be made of steel tubes, stainless steel tubes, copper tubes, etc. The fins can also be made of steel strips, stainless steel strips, copper strips, aluminum strips, etc. The finned heat exchanger uses mechanical winding, the contact surface between the heat dissipation fins and the heat dissipation tube is large and tight, the heat transfer performance is good and stable, the air resistance is small, and the steam or hot water flows through the steel tube. The heat is transferred to the air passing through the fins through the fins tightly wound on the steel tube, achieving the effect of heating and cooling the air.

[0003] For the heat exchanger fins used inside the water tank, since the fins of the traditional fin heat exchanger are fixed to the base tube by welding, if the local fins are bent due to extrusion or impact, the heat exchange effect will be affected, and the entire heat exchange tube can only be replaced, resulting in a waste of materials;

[0004] For this purpose, a heat exchanger fin is proposed in the patent with publication number CN112797835A, which facilitates the installation and removal of the fin by setting a first half and a second half. When a local fin is bent due to squeezing or impact, the local fin can be replaced, saving materials and reducing cost expenditure; however, its disassembly and assembly method is relatively complicated and inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a fin heat exchanger to solve the problem that the disassembly and assembly method is relatively complicated and inconvenient to use in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fin heat exchanger, comprising a fin, wherein the fin comprises a first half ring and a second half ring, the second half ring is located above the second half ring, a slide groove is provided on the upper surface of the second half ring along the circumferential direction, and a slider capable of cooperating with the slide groove is provided on the lower surface of the first half ring.

[0007] Preferably, the slide groove is a T-shaped slide groove, and the second half ring is a T-shaped slider.

[0008] Preferably, both ends of the slide groove are sealed ends.

[0009] Preferably, it further comprises a heat exchange pipe, and the fins are engaged with the outer surface of the heat exchange pipe.

[0010] Preferably, the outer surface of the heat exchange pipe is evenly provided with mounting grooves along the length direction, and the fins are located inside the mounting grooves.

[0011] Preferably, the first half ring and the second half ring are made of heat-conducting metal.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: in the utility model, when installation is required, the first half ring and the second half ring are first inserted into the outer surface of the heat exchange pipe, and then the first half ring is rotated so that the slider under the first half ring can slide inside the slide groove, so that the first half ring and the second half ring form a complete ring to achieve the purpose of heat exchange, and when one of the fins is damaged, the first half ring is rotated in the opposite direction so that the first half ring and the second half ring overlap again, and the state shown in the figure can be returned to the state again, and it can be conveniently removed.

When one of the fins 3 is damaged, the first half ring 31 is rotated in the opposite direction so that the first half ring 31 and the second half ring 32 overlap again, and the heat exchange pipe 1 can be restored to the original state.
