Abstract
Description
Technical Field
[0001] This invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger, which can be widely used in flat tube heat exchangers with built-in spiral fins. Background Technology
[0002] In existing flat tube heat exchangers, the built-in spiral vane flat tubes are subject to thermal expansion and contraction during the exchange of hot and cold gases, with the top of the tubes easily bearing downward force. Due to the lack of a reinforcing structure, firstly, the structural strength is low, making it highly susceptible to deformation under impact, thus affecting its performance; it has poor impact resistance, poor high-temperature resistance, and a short service life. Secondly, uneven stress within the built-in spiral vane flat tubes leads to deformation and a decrease in heat transfer efficiency. Summary of the Invention
[0003] The purpose of this invention is to provide a high-temperature impact-resistant flat tube heat exchanger with high structural strength, strong impact resistance, reliable protection, strong safety performance, long service life, good heat transfer effect, and high temperature resistance.
[0004] To achieve the above objectives, the present invention provides a high-temperature resistant and impact-resistant flat tube heat exchanger, comprising an outer cylinder, an inner cylinder located inside the outer cylinder and connected to the outer cylinder, a plurality of built-in spiral flat tubes installed on the inner wall of the inner cylinder, a reinforcing ring plate installed on the outer wall of the outer cylinder, a support reinforcement plate installed on the inner wall of the inner cylinder, a support bracket plate installed on the support reinforcement plate, flat tube reinforcement plates installed on both sides of each built-in spiral flat tube, and a flat tube connecting plate that is both installed on the support bracket plate and located between and installed on the two flat tube reinforcement plates.
[0005] The present invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger, wherein the bracket reinforcing plates are installed by welding, and each bracket reinforcing plate is firmly welded to the inner wall of the inner cylinder.
[0006] The present invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger, wherein the flat tube reinforcing plates are installed by welding, and each flat tube reinforcing plate is firmly welded to both sides of each built-in spiral flat tube.
[0007] The present invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger, wherein one end of the support plate is welded and fixed to the support reinforcement plate, and the other end only supports the flat tube connecting plate without welding to it, and can expand freely when affected by high temperature.
[0008] This invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger. It employs multiple reinforcing structures, including a reinforcing ring plate, a support reinforcement plate, a support bracket, a flat tube reinforcement plate, and a flat tube connecting plate, to distribute the forces acting on the internal spiral flat tubes. This improves the structural strength and impact resistance of the internal spiral flat tubes. Therefore, this invention features high structural strength, strong impact resistance, and will not deform under impact, providing reliable protection, strong safety performance, and a long service life.
[0009] This invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger. Because the internal spiral blade flat tube is subjected to uniform stress, it avoids damage to the internal spiral blade flat tube caused by thermal expansion and contraction. The internal spiral blade flat tube will not deform, thus it has good heat transfer effect and high temperature resistance.
[0010] The present invention relates to a high-temperature resistant and impact-resistant flat tube heat exchanger. The support plate has a fixed end at one end and a free end at the other end. The support plate can freely expand and contract when affected by temperature to compensate for dimensional changes caused by temperature differences. Therefore, it is resistant to high temperatures, achieves multi-directional expansion, and has a long service life.
[0011] In summary, the high-temperature resistant and impact-resistant flat tube heat exchanger of this invention has high structural strength, strong impact resistance, reliable protection, strong safety performance, long service life, good heat transfer effect, and high temperature resistance.
