Description

Technical Field

[0001] This utility model belongs to the technical field of heat pipe row air conditioning units, specifically relating to a chamfered heat exchanger. Background Technology

[0002] Currently, in-row heat pipe air conditioners use V-type heat exchangers as heat exchange components when there is a large cooling capacity requirement. The fan blows out the hot air from the room, which is cooled down as it flows through the heat exchanger. The refrigerant absorbs heat and heats up by flowing through copper pipes in the heat exchanger.

[0003] However, the current V-type heat exchanger design suffers from a poor airflow problem, such as... Figure 3 As shown, heat exchangers are typically square (i.e., their fins are square), resulting in a significant angle between the outlet airflow and the heat exchanger fins. This leads to airflow loss and higher fan energy consumption. Therefore, this issue needs to be addressed. Summary of the Invention

[0004] To address the problem that existing heat exchangers are square, resulting in a significant angle between the air outlet direction and the heat exchanger fins, leading to airflow loss and higher fan energy consumption, this invention provides a chamfered heat exchanger.

[0005] The chamfered heat exchanger of this utility model includes two fin groups connected at the bottom in a V-shape and connected at the top by a sheet metal connecting rod. Each fin group contains several fins of the same shape. Each fin has a lower end plate at the bottom, an upper end plate at the top, and side plates on both sides. The lower end plate, fins, and upper end plate are all parallelograms and are connected to form a parallelogram. The acute angles of the interior angles of the lower end plate, fins, and upper end plate are equal and are all between 30° and 70°. The sheet metal connecting rod is connected to the side plate, and the vertex of the fin edge contacted by the side plate is higher than the vertex of its opposite edge.

[0006] Furthermore, the acute angles in the inner angles of the lower end plate, fins, and upper end plate are all 60°.

[0007] Furthermore, the sheet metal connecting rod is fastened to the side plate by bolts, nuts, and bolts.

[0008] Furthermore, the side plate is an isosceles trapezoid, and the length of the side plate that contacts the fin is greater than the length of its opposite side.

[0009] Beneficial effects: This utility model's chamfered heat exchanger changes the traditional square fins to parallelograms, with the top interior angle being acute. The upper and lower end plates are also set as parallelograms, forming a single parallelogram when connected. As airflow passes through the heat exchanger, the included angle decreases, resulting in smoother airflow and reduced airflow loss and fan energy consumption. The chamfered heat exchanger has a larger size and a wider width within the standard specification. Furthermore, due to optimized airflow, it offers greater heat exchange performance. By setting the acute angles in the lower end plate, fins, and upper end plate to 60°, airflow loss and fan energy consumption are further reduced. Installation is convenient by using bolts, nuts, and side plates to fasten the sheet metal connecting rods. The side plates are designed as isosceles trapezoids, with the length of the side contacting the fins greater than the length of its opposite side, without obstructing the airflow.

Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0012] like Figure 1-2 As shown, this utility model is a chamfered heat exchanger, including two fin groups. The bottom of the two fin groups are connected in a V-shape, and the upper parts are connected by a sheet metal connecting rod 4. Each fin group includes several fins 1 of the same shape. Each fin 1 has a lower end plate 3 at the bottom, an upper end plate 2 at the top, and side plates 5 on both sides. The lower end plate 3, fins 1, and upper end plate 2 are all parallelograms and are connected to form a parallelogram. The acute angles of the interior angles of the lower end plate 3, fins 1, and upper end plate 2 are equal and all are 60°. Figure 2 The image shows an outer angle of 120°. The sheet metal connecting rod 4 is connected to the side plate 5, and the vertex of the fin edge that the side plate 5 contacts is higher than the vertex of its opposite edge (e.g., Figure 1 (As shown). The sheet metal connecting rod 4 is fastened to the side plate 5 by bolts and nuts; the side plate 5 is an isosceles trapezoid, and the length of the side (lower base) of the side plate 5 that contacts the fin 1 is greater than the length of its opposite side (upper base).

[0013] In the heat exchanger described above, the refrigerant pipes are connected to the copper pipes by brazing, which allows the refrigerant to flow; the copper pipes and fins 1 are fitted with an interference fit through tube expansion, which transfers heat from the refrigerant to the fins 1; the sheet metal connecting rod 4 is fastened to the side plate 5 by bolts, nuts and bolts, which fixes the heat exchanger; the upper end plate 2 and the lower end plate 3 reinforce the heat exchanger; the entire heat exchanger fins form a parallelogram with a "chamfered" shape.

[0014] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0015] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
