Description

Technical Field

[0001] This utility model relates to the field of air conditioning and refrigeration technology, specifically to a heat dissipation and air distribution structure for air conditioning and refrigeration. Background Technology

[0002] The evaporator is a crucial component of the four main refrigeration systems. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. It is widely used in various industrial equipment with refrigeration systems, such as household air conditioners, ships, and automobiles. In air conditioning structures, during the heat exchange process, due to the positional relationship between the evaporator and the cooling fan (generally, the cooling fan is closer to one end of the evaporator than the other), when the cooling fan draws air in from the air conditioner inlet, the airflow is uneven as it passes through the evaporator. This results in a larger airflow at the end of the evaporator closer to the cooling fan and a smaller airflow at the other end, leading to uneven airflow and poor heat exchange. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a heat dissipation and air distribution structure for air conditioning, which can distribute air evenly on the evaporator, thereby improving the heat exchange effect of the evaporator.

[0004] This utility model adopts the following technical solution: a heat dissipation and air distribution structure for air conditioning refrigeration, including a chassis. The interior of the chassis is divided by a partition to form a cooling space and an installation space for installing a cooling fan. The installation space and the cooling space are arranged vertically. An air outlet is provided on the chassis located in the installation space to draw airflow from the installation space out through the air outlet. An air inlet is provided on the chassis located in the cooling space. An evaporator is mounted on the chassis located at the air inlet. Airflow is introduced into the cooling space after passing through the air inlet and the evaporator. An air intake is provided on the partition. The cooling fan draws airflow from the cooling space into the installation space through the air intake. Symmetrically arranged air distribution plates are installed at the upper and lower ends of the evaporator. The air distribution plates are Z-shaped and extend into the cooling space at both ends to form independent air guide channels. The diameter of the air guide channels gradually decreases in the direction away from the air inlet.

[0005] Furthermore, the air distribution plate includes a connecting part, a constricted part, and an extension part, which are sequentially connected to form a Z-shaped structure; the connecting part is encapsulated and connected to the evaporator, and the constricted part is obliquely connected between the connecting part and the extension part; the air guide channel is formed between the constricted parts on the air distribution plates at both ends. Furthermore, the air outlet width of the air guide channel is greater than half the height of the evaporator; the evaporator is at least partially located within the cooling space; and the air guide channel is located in the middle of the evaporator. Furthermore, the extension direction of the extension is consistent with the horizontal direction, and the extension end of the extension does not exceed the axial position of the mounting center of the cooling fan; Furthermore, the included angles between the constricted portion, the connecting portion, and the extension portion are all obtuse angles; the length of the connecting portion is greater than the width of the evaporator; Furthermore, sealing strips are installed at the connection points between the evaporator and the air inlet of the casing, and the sealing strips are made of ethylene propylene rubber.

[0006] The beneficial effect of this utility model is that by setting symmetrical air distribution plates at the upper and lower ends of the evaporator, it can ensure that each position of the evaporator receives the same air volume and forms the same air resistance path. This forces the air in the upper part of the evaporator to be pushed to the lower part of the evaporator, thereby playing a role in equalizing the airflow in the evaporator and improving the heat exchange effect of the evaporator. It has good economic value. Attached Figure Description

[0008] like Figure 1 , Figure 2 As shown, this utility model discloses a heat dissipation and air distribution structure for air conditioning refrigeration, including a casing 1. The casing 1 is divided by a partition 2 to form a cooling space 3 and an installation space 5 for mounting a cooling fan 4. The installation space 5 and the cooling space 3 are arranged vertically to ensure that airflow can enter the cooling space 3 from the evaporator 6 fins. An air outlet 7 is provided on the casing 1 located in the installation space 5 to guide the airflow from the installation space 5 out through the air outlet 7. An air inlet 8 is provided on the casing 1 located in the cooling space 3. The evaporator 6 is mounted on the chassis 1 located at the air inlet 8. The airflow passes through the air inlet 8 and the evaporator 6 and is then introduced into the cooling space 3. The partition 2 has an air intake 9, and the cooling fan 4 introduces the airflow in the cooling space 3 into the installation space 5 through the air intake 9. The upper and lower ends of the evaporator 6 are equipped with symmetrically arranged air distribution plates 10. The air distribution plates 10 are Z-shaped and extend into the cooling space 3 to form independent air guide channels 11. The diameter of the air guide channels 11 gradually decreases in the direction away from the air inlet 8.

[0009] The air distribution plate 10 includes a connecting part 12, a constricted part 13, and an extension part 14, which are connected in sequence to form a Z-shaped structure. The connecting part 12 is encapsulated and connected to the evaporator 6, and the constricted part 13 is obliquely connected between the connecting part 12 and the extension part 14. An air guide channel 11 is formed between the constricted parts 13 on the air distribution plates 10 at both ends.

[0010] The air outlet width d of the air guide channel 11 is greater than half the height of the evaporator 6; the evaporator 6 is at least partially located within the cooling space 3; the air guide channel 11 is located in the middle of the evaporator 6; the extension direction of the extension 14 is consistent with the horizontal direction, and the extension end of the extension 14 does not exceed the axis position of the mounting center of the cooling fan 4, which is conducive to the formation of the overall air guide channel; if it exceeds this, it will block the inlet air intake of the cooling fan 4. The included angles between the constricted portion 13, the connecting portion 12, and the extension 14 are all obtuse angles (e.g., 120°); the length of the connecting portion 12 is greater than the width of the evaporator 6; The connection between the evaporator 6 and the air inlet 8 of the casing 1 is equipped with sealing strips (not shown in the figure), which are made of ethylene propylene rubber. If there is a gap between the evaporator 6 and the casing 1, it may cause airflow short circuit. By setting the sealing strips, the airflow short circuit can be blocked.

[0011] In this invention, the symmetrically arranged air distribution plates 10 at the upper and lower ends of the evaporator 6 facilitate the formation of a complete air guide channel 11. When the incoming air passes through the evaporator 6, since the diameter of the air guide channel 11 gradually decreases away from the air inlet 8, and since the air guide channel 11 is located in the middle of the evaporator 6, the incoming air will reach each position of the evaporator 6 with the constriction of the air guide channel 11 as the center, forming a symmetrical structure. This allows each position of the evaporator 6 to receive the same air volume, resulting in the same air resistance path. That is, the airflow resistance from each position of the evaporator 6 to the center of the cooling fan 4 is similar, which is conducive to the realization of air distribution. This allows the air in the upper part of the evaporator 6 to be forced to the lower part of the evaporator 6, thereby playing a role in air distribution in the evaporator 6 and improving the heat exchange effect of the evaporator 6.

[0012] In summary, this invention not only achieves uniform airflow and heat dissipation, but also improves the efficiency of the evaporator 6, allowing the refrigerant in the air conditioning pipes to fully evaporate and improving the cooling effect.
