Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to an indoor condenser. Background Technology

[0002] Currently, new energy vehicles on the market are increasingly using heat pump air conditioning systems to address battery degradation issues in low-temperature winter conditions. The indoor condenser is a crucial component of this system, primarily responsible for warming incoming cold air and delivering it into the vehicle to meet heating needs. However, existing indoor condensers employ a dual-row cold airflow design, resulting in a complex structure and significant space requirements. The fins within require dual-row splicing, leading to complex assembly processes. During welding, fins are prone to falling off or misaligning, affecting air resistance and heat exchange capacity, resulting in poor heat exchange performance and an inability to effectively handle the increased heating demands of the entire vehicle. Utility Model Content

[0003] The purpose of this utility model is to provide an indoor condenser with a simple structure and high strength, which can avoid the problem of heat dissipation fins falling off or misaligning during the welding and assembly process, while reducing wind resistance loss and improving heat exchange efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution: an indoor condenser, comprising two tube assemblies and multiple heat dissipation fins. Each tube assembly includes two manifolds and a branch pipe group. The branch pipe group includes multiple flat tubes, which are parallel to each other and spaced apart between the two manifolds. Both ends of each manifold are connected to the two manifolds respectively. The manifolds on both sides of the two tube assemblies are correspondingly connected to form a heat dissipation channel for refrigerant flow. The heat dissipation fins and the flat tubes are staggered and welded together. In the width direction of the flat tubes, the width of the heat dissipation fins is greater than or equal to the total width of the two branch pipe groups. Each heat dissipation fin includes multiple sequentially connected heat dissipation plates, each heat dissipation plate having a reinforcing structure at its four corners, the reinforcing structure abutting against the flat tube.

[0005] Preferably, the heat sink has a first hollow portion and a second hollow portion that are connected. The first hollow portion and the second hollow portion are symmetrically arranged. The first hollow portion corresponds to the position of one of the shunt pipe groups, and the second hollow portion corresponds to the position of the other shunt pipe group.

[0006] Preferably, the first hollow portion includes a plurality of oblique teeth, and a gap is formed between two adjacent oblique teeth for airflow to pass through.

[0007] Preferably, in the width direction of the heat sink, two of the reinforcing structures located on the same side of the heat sink cooperate to form a slot, and two corresponding flat tubes of the two tube assemblies are confined within the slot.

[0008] Preferably, the reinforcing structure includes a planar portion and an inclined portion, the planar portion being flush with the side end face of the heat sink, and the inclined portion protruding from the surface of the heat sink along the width direction of the heat sink.

[0009] Preferably, the inclined portion and the heat dissipation fins are connected by an arc surface.

[0010] Preferably, the heat sink is provided with arc-shaped connecting parts on both sides, and two adjacent heat sinks are connected through the connecting parts. The reinforcing structure is provided at both ends of the connecting parts on the side away from the heat sink.

[0011] Preferably, the two adjacent heat sinks are arranged at an angle.

[0012] Preferably, the indoor condenser also includes two side plates, which are located on both sides of the diversion pipe assembly, and the heat dissipation fins are also provided between the side plates and the diversion pipe assembly.

[0013] Preferably, the indoor condenser further includes a baffle plate located between two corresponding connected manifolds.

[0014] The beneficial effects of this utility model are as follows: By setting heat dissipation fins with a width greater than or equal to the total width of two branch pipe groups, one heat dissipation fin can be welded and fixed to four flat tubes on both sides. The heat dissipation fins do not need to be spliced, which effectively simplifies the structure of the indoor condenser, improves production efficiency and overall strength, and the integrated heat dissipation fins can effectively reduce wind resistance loss at the inlet and outlet of the channel within a limited heat exchange area, thus improving heat exchange efficiency. By setting reinforcing structures at the four corners of each heat dissipation plate in the heat dissipation fins, and by having these reinforcing structures abut against the flat tubes on both sides of the heat dissipation fins, the heat dissipation fins are positioned, preventing them from falling off or misaligning during welding and assembly, effectively improving the installation stability and ease of assembly of the heat dissipation fins.

[0024] Reference Figures 1 to 4As shown, an indoor condenser according to an embodiment of this application includes two tube assemblies 100 and multiple heat dissipation fins 200. Each tube assembly 100 includes two manifolds 110 and a branch pipe group 120. The branch pipe group 120 includes multiple flat tubes 121, which are parallel to each other and spaced apart between the two manifolds 110. Both ends of each manifold 110 are connected to the two manifolds 110 respectively. The manifolds 110 on both sides of the two tube assemblies 100 are correspondingly connected to form a heat dissipation channel for refrigerant flow. One manifold 110 in one tube assembly 100 has a refrigerant inlet communicating with the heat dissipation channel, and the manifold 110 in the other tube assembly 100 has a refrigerant outlet communicating with the heat dissipation channel. The refrigerant inlet and outlet are arranged side-by-side and connected to the same pipe head 111.

[0025] The heat dissipation fins 200 and flat tubes 121 are arranged alternately. In the width direction of the flat tubes 121, the width of the heat dissipation fins 200 is greater than or equal to the total width of the two shunt tube groups 120, so that in the length direction of the tube assembly 100, the heat dissipation fins 200 located between two adjacent flat tubes 121 are welded and fixed to the four flat tubes 121 on both sides respectively.

[0026] The heat dissipation fins 200 include a plurality of heat dissipation plates 210 connected in sequence. The heat dissipation plates 210 are rectangular, and each heat dissipation plate 210 has a protruding reinforcing structure 211 at each of its four corners. The reinforcing structure 211 abuts against the flat tube 121.

[0027] Understandably, by setting heat dissipation fins 200 with a width greater than or equal to the total width of two branch pipe groups 120, one heat dissipation fin 200 can be welded and fixed to four flat tubes 121 on both sides. The heat dissipation fins 200 do not need to be spliced, which effectively simplifies the indoor condenser structure, improves production efficiency and overall strength, and the integrated heat dissipation fins 200 can effectively reduce airflow resistance loss on the heat dissipation fins 200 within a limited heat exchange area, thus improving heat exchange efficiency. By setting reinforcing structures 211 at the four corners of each heat dissipation plate 210 in the heat dissipation fins 200, and the reinforcing structures 211 abutting against the flat tubes 121 on both sides of the heat dissipation fins 200, the heat dissipation fins 200 are positioned, preventing them from falling off or misaligning during welding and assembly, effectively improving the installation stability and assembly convenience of the heat dissipation fins 200.

[0028] Furthermore, arc-shaped connecting portions 214 are provided on both sides of the heat sink 210, and two adjacent heat sinks 210 are connected through the connecting portions 214. The reinforcing structure 211 is provided at both ends of the connecting portion 214 on the side away from the heat sink 210.

[0029] By connecting the heat sink 210 with an arc-shaped connecting part 214, stress concentration between adjacent heat sinks 210 can be reduced, providing higher tensile and compressive strength, thereby improving the overall performance of the heat sink fins 200. In addition, the arc-shaped connecting part 214 between two adjacent heat sinks 210 can be processed by stamping or bending, improving the production efficiency of the heat sink fins 200.

[0030] Furthermore, the adjacent heat sinks 210 are arranged at an angle, that is, the multiple heat sinks 210 are arranged in a V-shape.

[0031] Arranging two adjacent heat sinks 210 at an angle can improve the compactness of multiple heat sinks 210, allowing for a greater number of heat sinks 210 to be arranged within a limited length, thereby improving the heat dissipation efficiency of the heat dissipation fins 200.

[0032] In some embodiments, two adjacent heat sinks 210 can also be arranged in parallel, and the two adjacent heat sinks 210 are connected by a straight connecting part 214, thereby simplifying the structure of the heat sink fins 200 and facilitating the processing of the heat sink fins 200.

[0033] Reference Figures 2 to 4 As shown, it can be understood that the heat sink 210 is provided with a first hollow portion 212 and a second hollow portion 213 that are connected. The first hollow portion 212 and the second hollow portion 213 are symmetrically arranged. The first hollow portion 212 corresponds to one of the shunt pipe groups 120, and the second hollow portion 213 corresponds to the other shunt pipe group 120. In other words, the first hollow portion 212 and one of the shunt pipe groups 120 are spaced apart in the length direction of the pipe body assembly 100, and the second hollow portion 213 is spaced apart in the length direction of the other shunt pipe group 120. The two shunt pipe groups 120 are spaced apart in the width direction of the pipe body assembly 100.

[0034] By setting the first hollow part 212 and the second hollow part 213, the same airflow can exchange heat with the sidewalls of the two flat tubes 121 corresponding to the two split tube groups 120, further reducing the airflow resistance loss on the heat dissipation fins 200 and improving the heat dissipation efficiency of the heat dissipation fins 200.

[0035] Reference Figure 3 and Figure 4 As shown, it can be understood that the first hollow portion 212 includes multiple helical teeth 2121, and a gap is formed between two adjacent helical teeth 2121 to allow airflow to pass through. The structure of the second hollow portion 213 is the same as described above regarding the first hollow portion 212, and will not be repeated here.

[0036] By setting multiple helical teeth 2121, the heat sink 210 forms multiple heat dissipation channels at the first hollow part 212. When the airflow passes through the first hollow part 212, it exchanges heat with both sides of each helical tooth 2121, thereby greatly increasing the contact area between the airflow and the first hollow part 212 and ensuring the heat exchange capacity of the heat sink fins 200.

[0037] Reference Figure 1 and Figure 3 As shown, it can be understood that in the width direction of the heat sink 210, two reinforcing structures 211 located on the same side of the heat sink 210 cooperate to form a slot, and the two corresponding flat tubes 121 in the two tube body assemblies 100 are confined within the slot. In other words, the two opposite sides of the two adjacent flat tubes 121 in the width direction of the heat sink 210 are engaged with the two reinforcing structures 211.

[0038] Two reinforcing structures 211 form slots to hold two corresponding flat tubes 121. On the one hand, the slots can increase the contact area between the reinforcing structure 211 and the flat tube 121, further improving the installation stability of the heat dissipation fins 200. On the other hand, the slots on both sides of the multiple heat dissipation plates 210 cooperate to form a positioning structure on both sides of the heat dissipation fins 200, which facilitates the alignment of the heat dissipation fins 200 and further improves the assembly convenience of the heat dissipation fins 200.

[0039] Reference Figure 3 As shown, the reinforcing structure 211 includes a planar portion 2111 and an inclined portion 2112. The planar portion 2111 is flush with the side face of the heat sink 210 (i.e., the side face of the connecting portion 214). The inclined portion 2112 protrudes from the surface of the heat sink 210 along the width direction of the heat sink 210. When the connecting portion 214 is arc-shaped, the reinforcing structure 211 is a conical structure protruding from the generatrix of the arc-shaped connecting portion 214. At this time, the projection of the reinforcing structure 211 onto the heat sink 210 is a right-angled triangle, and one right-angled side of the triangle is collinear with the short side of the projection of the heat sink 210.

[0040] By setting the flat part 2111 and the inclined part 2112, the shape of the reinforcement structure 211 can be simplified, making the design and processing of the reinforcement structure 211 more convenient. Furthermore, the inclined part 2112 of the reinforcement structure 211 can be tangent to the rounded corner of the edge of the flat tube 121, increasing the stress between the reinforcement structure 211 and the flat tube 121, and further improving the installation stability of the heat dissipation fins 200.

[0041] Furthermore, the inclined portion 2112 and the heat dissipation fins 200 (or the surface of the connecting portion 214) are transitioned by an arc surface.

[0042] By setting the end of the arc-shaped excessively inclined part 2112 and the heat dissipation fins 200, the stress exerted by the flat tube 121 on the reinforcement structure 211 can be evenly distributed, reducing stress concentration, improving the overall strength and rigidity of the heat dissipation fins 200, and reducing the risk of fracture and deformation of the reinforcement structure 211.

[0043] Reference Figure 1 As shown, it can be understood that the indoor condenser also includes two side plates 130, which are symmetrically arranged on both sides of the branch pipe group 120 along the length of the pipe assembly 100. Heat dissipation fins 200 are also provided between the side plates 130 and the branch pipe group 120.

[0044] By setting the side plate 130, on the one hand, the side plate 130 can hide the heat dissipation fins 200 on both sides of the tube assembly 100, effectively improving the appearance of the indoor condenser; on the other hand, the integrally formed side plate 130 and the heat dissipation fins 200 spanning the two side plates 130 are welded and fixed, which can indirectly fix the two shunt tube groups 120, effectively improving the overall structural stability of the indoor condenser.

[0045] Furthermore, the indoor condenser also includes a baffle 140, which is located between two corresponding connected manifolds 110 and extends into the two manifolds 110. Multiple baffles 140 can be selectively provided according to the flow path of the refrigerant, and multiple baffles 140 are spaced apart along the length of the pipe assembly 100.

[0046] By setting up the partition 140, the two corresponding connected manifolds 110 can be fixed, and the flow direction distribution of the refrigerant in the entire pipe assembly 100 can be adjusted, effectively solving the problem of uneven temperature on the air outlet side. It can also prevent the refrigerant from shaking or shifting between the two manifolds 110 during the flow process, further improving the overall structural stability of the indoor condenser.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
