Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchanger with a high disturbance rate. Background Art

[0002] Existing heat exchangers exchange heat energy through channeling tubes and fins. In order to maximize thermal efficiency and maintain the balance between flue gas and pressure difference, the number of fins is usually increased to improve thermal efficiency. The shape and number of fins directly affect the heat exchange efficiency and flue gas emissions of the heat exchanger. Changes in the shape of the fins will change the flow path and speed of the flue gas in the heat exchanger, thereby affecting the heat exchange efficiency and flue gas emissions.

[0003] If the fin shape changes too much, it may cause smoke emissions to exceed the standard. Therefore, it is necessary to accurately calculate and adjust the number and shape of the fins to ensure that the heat exchange efficiency and smoke emissions meet the standard requirements. The current effective solution is to maximize the straightness of the fins and minimize the convex shape to reduce the resistance and pressure changes to achieve a balance.

[0004] However, in actual use, it is found that when the fins remain straight, the heat exchange efficiency is low. Therefore, it is hoped that a fin can be designed to reduce the number of fins while ensuring the efficiency of the heat exchanger to meet existing needs, reduce corresponding costs, and keep the flue gas and pressure within the specified standard range.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] The utility model provides a heat exchanger with a high disturbance rate, so as to solve the problem that the heat exchange effect of the heat exchanger in the prior art is poor and cannot meet the use requirements.

[0029] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 3 A high disturbance rate heat exchanger in an embodiment of the present application comprises a heat exchange tube 1, a connecting plate 2, a water inlet pipe 3, a water outlet pipe 4, a connecting pipe 6 and a fin portion; a plurality of the heat exchange tubes 1 are arranged relatively in parallel; two connecting plates 2 are respectively arranged at both ends of the heat exchange tube 1, for connecting the two ends of the plurality of heat exchange tubes 1 together; one end of the plurality of heat exchange tubes 1 is communicated with each other through the connecting pipe 6, and a water inlet pipe 3 is provided on one side, and the other end of the plurality of heat exchange tubes 1 is communicated with each other through the connecting pipe 6, and a water outlet pipe 4 is provided on one side; the fin portion is arranged perpendicular to the plurality of heat exchange tubes 1, and is located between the two connecting plates 2.

[0030] The fin portion includes a plurality of fins 5 arranged relatively in parallel, and the plurality of heat exchange tubes 1 sequentially pass through the plurality of parallel fins 5; the fins 5 have a plurality of through holes 51 for the plurality of heat exchange tubes 1 to fit through, and between every two of the through holes 51 are a plurality of bridge components 52 and a plurality of hole-turning components 53 arranged up and down, for disturbing the airflow and generating cross disturbance.

[0031] The heat exchanger with a high disturbance rate of the utility model has a simple overall structure. Through the multiple bridge components 52 and multiple hole-turning components 53 arranged from bottom to top, the airflow is blocked and disturbed, so that the airflow stays in the heat exchanger tube 1 for a long time and is absorbed; at the same time, a cross-disturbance effect of the airflow is generated between the fins 5, so that more airflow can be absorbed by the heat exchange tube 1 as much as possible. When the fins are reduced, the heat exchange efficiency is not reduced, the heat exchange effect of the heat exchanger is improved, which meets the actual use requirements and reduces the cost to a certain extent.

[0032] In this embodiment, the shape of the heat exchange tube 1 is elliptical. Compared with the circular heat exchange tube 1, the elliptical shape has a high heat exchange efficiency, thereby further improving the heat exchange effect of the entire heat exchanger.

[0033] based on Figures 3 to 6 Furthermore, the bridge component 52 includes a first disturbance hole 520 opened on the fin 5, and the first disturbance hole 520 is in a long strip shape; a spoiler straight plate 521 is provided above the first disturbance hole 520, and the two ends of the spoiler straight plate 521 are connected to the two sides of the first disturbance hole 520 through spoiler inclined plates 522, so that gaps for airflow to flow are left between the first disturbance hole 520 and the spoiler straight plate 521 and the spoiler inclined plates 522. The airflow passes through the gap and passes through the first disturbance hole 520 and then enters other heat exchange tubes, thereby improving the efficiency of the heat exchange tube 1 in absorbing energy.

[0034] Specifically, in the present embodiment, three bridge components 52 of different lengths are arranged in sequence up and down, and the lengths of the three bridge components 52 are 7.3 mm, 15.3 mm, and 10.5 mm, respectively; in this way, the airflow flowing from bottom to top first encounters the spoiler straight plate 521 and the two spoiler inclined plates 522 and is then blocked, and the airflow can have more time to stay in the heat exchange tube 1 to be absorbed, and at the same time, the airflow will flow to the first disturbance hole 520 to form a cross disturbance, so that the heat exchange tube 1 can absorb more heat. The provision of three bridge components 52 can further improve the heat exchange efficiency.

[0035] Furthermore, the hole-turning component 53 in this embodiment includes a second disturbance hole 530 opened on the fin 5; the second disturbance hole 530 is circular, and a protruding hollow circular spoiler 531 is provided outward along the edge of the second disturbance hole 530; when the airflow flows from the bridge component 52 to the hole-turning component 53, the spoiler 531 also blocks the airflow, and the airflow can stay in the heat exchange tube 1 for more time to be absorbed, and the airflow will also enter the second disturbance hole 530 to form a cross-disturbed airflow.

[0036] During operation, when the airflow flows upward from the bottom of the fin 5, it will be blocked by the bridge component 52 and the hole-turning component 53 in a timely manner during the entire flow process, so that the airflow stays at the heat exchange tube 1 long enough to be absorbed by the heat exchange tube 1, and cross-disturbance of the airflow will be generated between the entire part of the fin 5. The range of the cross-disturbance is large, which can drive more airflow to be absorbed by the heat exchange tube 1, effectively improving the heat exchange performance of the heat exchanger.

[0037] Furthermore, in the present embodiment, the number of the perforated components 53 is three, and the three perforated components are arranged in an equilateral triangle, so that the three spoilers 531 on the three perforated components 53 form an encirclement within a small range, which allows the airflow to stay for a longer time, and the smoke also stays there for a longer time, which relatively reduces the emission of smoke in the same period of time, so that the heat exchange efficiency and the smoke exhaust are relatively balanced.

[0038] Furthermore, circular third disturbance holes 540 are provided on the fins 5 at both ends of the hole-turning component 53, so that when the airflow flows upward, turbulence is generated when passing through the third disturbance holes 540, thereby enhancing the heat transfer effect and further improving the thermal efficiency.

[0039] In actual use, the airflow generating hot air flows upward from the bottom of the exchanger. The airflow first encounters three bridge components 52 arranged vertically. Part of the airflow is blocked by the bridge component 52, part of the airflow flows directly upward, and the other part enters the rear of the fin through the first disturbance hole 520, thereby generating cross disturbance of the airflow. Due to the blocked airflow and the cross disturbance of the airflow, the heat exchanger 1 at the fin can absorb more heat energy; then the airflow enters the local area formed by the three hole-turning components 53, part of the airflow flows upward, and the other part of the airflow is blocked in the hole-turning component 53. In the encirclement formed by the component 53, more energy is absorbed by the heat exchange tube after a long stay, and the remaining part enters the back of the fin 5 through the second disturbance hole 530, thereby generating cross disturbance between the fins 5. Because more airflow flows to the fins, the heat exchange tube can absorb more energy; finally, a part of the remaining airflow flows directly upward, and another part generates turbulence when passing through the third disturbance hole 540, further improving the heat exchange effect. In addition, due to the similar encirclement formed by the three flip-hole components 53, the exhaust of smoke can be slowed down to a certain extent, meeting the actual use needs.

[0040] The high disturbance rate heat exchanger of the utility model is provided with a plurality of bridge components and a plurality of hole-turning components. When the airflow passes through the bridge components and the hole-turning components, turbulence and cross-disturbance are generated, so that the original direct upward airflow is changed into cross-disturbance and expanded, so that the airflow generating heat energy is more absorbed by the heat exchange tube, thereby improving the heat exchange efficiency. Thus, while reducing the number of fins, the heat exchange efficiency is ensured, and the production cost can also be reduced.

[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
