Description

Technical Field

[0001] The utility model relates to a refrigeration device, in particular to a condensing unit. Background Art

[0002] The condensing unit includes a condenser. When working, the refrigerant in the condenser needs to exchange heat with the air and cool down. Therefore, in order to improve the heat exchange effect of the condenser, the condenser is set with a larger area, thereby increasing the heat exchange area with the air. However, when the area of ​​the condenser is increased, the lateral volume occupied by the entire condensing unit will increase, affecting the installation of the condensing unit. Therefore, a condensing unit that can both increase the heat exchange effect and be easy to install and use is needed. Utility Model Content

[0003] The utility model aims to provide a condensing unit to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A condensing unit comprises: a base, a top side of which is connected to a heat exchange box, a cavity interconnected with the heat exchange box is arranged in the base, the heat exchange box extends in a ring shape on the top side of the base, a storage cavity is formed between the heat exchange box and the top side of the base, an air outlet is arranged on the top side of the heat exchange box, and an air inlet interconnected with the cavity is arranged on the bottom side of the base; a condenser connected to the heat exchange box; a fan connected to the cavity, an air inlet end of the fan is opposite to the air inlet; a compressor connected to the storage cavity, and the compressor and the condenser are interconnected.

[0006] This technical solution has at least the following beneficial effects: a cavity for air intake is provided inside the base, a heat exchange box is provided on the top side of the base, the cavity and the internal space of the heat exchange box are interconnected, and when the fan is working, air is taken in from the air inlet on the bottom side of the base box, the air enters the cavity and then flows into the heat exchange box, at this time the air exchanges heat with the condenser located in the heat exchange box, and then is discharged from the air outlet on the top side of the heat exchange box. Since the heat exchange box extends in a ring shape on the top side of the base, the condenser can also extend in a ring shape in the heat exchange box, which can increase the heat exchange area of ​​the condenser and better control the lateral occupied area, thereby better controlling the condensing unit to occupy a smaller installation space, which not only improves the overall heat exchange efficiency, but also increases the convenience of installation and use.

[0007] As a further improvement of the above technical solution, the condenser includes a condenser tube and a fin. The condenser tube spirally extends around the center line of the heat exchange box in the heat exchange box, and the fin is connected to the outside of the condenser tube. The fin extends in the up-down direction. One end of the refrigerant tube is connected to the compressor, and the other end is used to connect to an external device. The refrigerant tube spirally extends in the heat exchange box, which effectively increases the heat exchange stroke of the refrigerant tube. The heat of the refrigerant tube can also be directly transferred to the fin, and the fin is used to further increase the contact area with the air. The fin extends in the up-down direction. When the air enters the heat exchange box, it can flow upward along the fin and exchange heat, so that the air can be discharged from the air outlet on the top side of the heat exchange box.

[0008] As a further improvement of the above technical solution, the heat exchange box includes an inner baffle, an outer baffle and an upper baffle. The shapes of the inner baffle and the outer baffle are both annular. The outer baffle is arranged at intervals on the outer side of the inner baffle. The upper baffle is connected between the top side of the inner baffle and the top side of the outer baffle. The upper baffle is provided with the air outlet. A space is formed between the inner baffle, the outer baffle and the upper baffle to surround and accommodate the condenser. When air enters the space, the inner baffle can block the air so that the air does not flow to the compressor installed in the storage cavity. When the air flows to the upper baffle on the top side, it will also flow out from the mesh on the outer baffle. This can increase the heat dissipation efficiency of the condenser and allow heat to be discharged from the heat exchange box faster.

[0009] As a further improvement of the above technical solution, the outer side of the outer baffle is connected with an air guide rib, the air guide rib extends obliquely in the up-down direction, and a plurality of air guide ribs are arranged around the outer side of the outer baffle at intervals. Part of the airflow blown out from the outer baffle flows along the air guide rib, and because the air guide rib extends obliquely in the up-down direction, part of the airflow blown out can flow upward around the outer side of the outer baffle along the air guide rib, thereby better improving the air flow outside the outer baffle, thereby improving the heat exchange efficiency inside the heat exchange box.

[0010] As a further improvement of the above technical solution, the wind guide edge extends downwardly at an angle away from the outer baffle. Since the airflow entering the heat exchange box is generally in an upward flow direction, the airflow flowing out from the outer baffle will also have an upward flow speed. At this time, the wind guide edge inclined downward can block the airflow flowing out from the outer baffle, increase the airflow flowing along the wind guide edge, and make the airflow flowing up and down along the wind guide edge cover a larger range, thereby better improving the air flow outside the outer baffle, and further improving the heat exchange efficiency of the heat exchange box.

[0011] As a further improvement of the above technical solution, the outer baffle is detachably connected to the base. When the condenser inside the heat exchange box needs to be maintained, the outer baffle can be removed to expose the condenser, which can improve the convenience of maintaining and replacing the condenser and further improve the user experience.

[0012] As a further improvement of the above technical solution, a connecting ring is connected to the bottom side of the outer baffle, a connecting groove is provided on the top side of the base, and the connecting ring is connected in the connecting groove. The bottom side of the outer baffle is connected to the connecting ring, and the connecting ring can be used to strengthen the structural strength of the bottom side of the outer baffle, so that the outer baffle is not easy to twist and deform, and when the outer baffle is installed on the base, the cooperation of the connecting ring and the connecting groove can realize the rapid installation of the outer baffle and the base, thereby improving the installation efficiency of the entire condensing unit.

[0013] As a further improvement of the above technical solution, the inner top surface of the cavity is a conical surface with a larger top and a smaller bottom. When the fan is working, air enters from the air inlet and then blows upward to the inner top surface of the cavity. Since the inner top surface of the cavity is a conical surface with a larger top and a smaller bottom, the wind blowing toward the inner top surface of the cavity can be guided and evenly flows into the heat exchange box located outside the conical surface, which is conducive to evenly distributing the fan exhaust air and improving the heat exchange efficiency of the condenser.

[0014] As a further improvement of the above technical solution, a pulley is connected to the bottom side of the base. When the whole needs to be moved, the pulley on the bottom side of the base can be used to conveniently move the whole, thereby improving the convenience of the whole use.

[0023] Reference Figure 1 and Figure 2A condensing unit comprises a base 100, a condenser, a fan and a compressor 400, wherein a heat exchange box 200 is connected to the top side of the base 100, and a cavity communicating with the heat exchange box 200 is arranged in the base 100, that is, the cavity formed by the heat exchange box 200 has a lower opening arranged downward, and the cavity in the base 100 has an upper opening arranged upward, so that the cavity of the heat exchange box 200 is communicated with the cavity in the base 100, and the heat exchange box 200 extends in a ring shape on the top side of the base 100, and a storage cavity 210 is formed between the heat exchange box 200 and the top side of the base 100, and the heat exchange box 200 is arranged in a ring shape on the top side of the base 100. 0 is provided with an air outlet 211 on the top side, and an air inlet 110 interconnected with the cavity is provided on the bottom side of the base 100. The condenser is connected in the heat exchange box 200, and the fan is connected in the cavity. The air inlet end of the fan is directly opposite to the air inlet 110. In actual application, there is an air inlet gap between the air inlet end of the fan and the placement surface of the external device, so as to ensure that air can be introduced into the cavity from the air inlet 110. Similarly, there is an air outlet gap between the air outlet end of the fan and the inner top surface of the cavity, so as to ensure that the fan can blow air into the cavity. The compressor 400 is connected in the storage cavity 210, and the compressor 400 and the condenser are interconnected.

[0024] As can be seen from the above, a cavity for air intake is provided inside the base 100, and a heat exchange box 200 is provided on the top side of the base 100. The cavity is connected to the internal space of the heat exchange box 200. When the fan is working, air is taken in from the air inlet 110 on the bottom side of the bottom box, and the air enters the cavity and then flows into the heat exchange box 200. At this time, the air exchanges heat with the condenser located in the heat exchange box 200, and then is discharged from the air outlet 211 on the top side of the heat exchange box 200. Since the heat exchange box 200 extends in a ring shape on the top side of the base 100, the condenser can also extend in a ring shape in the heat exchange box 200. This can increase the heat exchange area of ​​the condenser and better control the lateral occupied area, thereby better controlling the condensing unit to occupy a smaller installation space, which not only improves the overall heat exchange efficiency, but also increases the convenience of installation and use.

[0025] As a specific structural embodiment of the condenser, the condenser includes a condenser tube 310 and a fin 320. The condenser tube 310 extends spirally around the center line of the heat exchange box 200 in the heat exchange box 200. The fin 320 is connected to the outside of the condenser tube 310. The fin 320 extends in the up and down directions. In actual applications, a plurality of fins 320 are arranged at intervals around the center line of the heat exchange box 200 in the heat exchange box 200, and holes for the condenser tube 310 to pass through are provided on the fin 320. When the condenser tube 310 extends spirally, it passes through the holes on the plurality of fins 320, thereby realizing an overall integrated connection. One end of the refrigerant pipe is connected to the compressor 400, and the other end is used to connect to external equipment. The refrigerant pipe extends spirally in the heat exchange box 200, which effectively increases the heat exchange range of the refrigerant pipe. The heat of the refrigerant pipe can also be directly transferred to the fins 320. The fins 320 are used to further increase the contact area with the air. The fins 320 extend in the up and down directions. When the air enters the heat exchange box 200, it can flow upward along the fins 320 and exchange heat, so that the air can be discharged from the air outlet on the top side of the heat exchange box 200.

[0026] In the above embodiments, the heat exchange box 200 may only have an air outlet 211 connected to the outside arranged on the upper part, while in the present embodiment, the heat exchange box 200 includes an inner baffle plate 220, an outer baffle net 230 and an upper baffle net, the shape of the inner baffle plate 220 and the shape of the outer baffle net 230 are both annular, the outer baffle net 230 is arranged at intervals on the outer side of the inner baffle plate 220, the upper baffle net is connected between the top side of the inner baffle plate 220 and the top side of the outer baffle net 230, and the air outlet 211 is arranged on the upper baffle net. The inner baffle plate 220, the outer baffle net 230 and the upper baffle net form a space for surrounding and accommodating the condenser. When air enters the space, the inner baffle plate 220 can block the air so that the air does not flow to the compressor 400 installed in the storage chamber 210. When the air flows to the upper baffle net on the top side, it will also flow outward from the mesh holes on the outer baffle net 230, thereby increasing the heat dissipation efficiency of the condenser and allowing the heat to be discharged from the heat exchange box 200 more quickly. In actual applications, the high-temperature refrigerant can be introduced from the end of the heat exchange tube located at the bottom of the heat exchange box 200. At this time, the air blown into the heat exchange box 200 directly exchanges heat with the high-temperature refrigerant, and then part of the high-temperature air after heat exchange is dissipated outward from the outer baffle net 230. As the high-temperature refrigerant gradually flows upward in the heat exchange box 200, the remaining air can also gradually flow upward in the heat exchange box 200 and continue to exchange heat with it.

[0027] The airflow blown out from the mesh holes on the outer baffle 230 usually directly diffuses to the surroundings. In order to better utilize the airflow blown out from the outer baffle 230 to remove the temperature of the surface of the heat exchange box 200, in this embodiment, the outer side of the outer baffle 230 is connected with an air guide rib 240, and the air guide rib 240 extends obliquely in the up-down direction. A plurality of air guide ribs 240 are arranged at intervals around the outer side of the outer baffle 230. Part of the airflow blown out from the outer baffle 230 flows along the air guide rib 240. Since the air guide rib 240 extends obliquely in the up-down direction, part of the airflow blown out can flow upward around the outer side of the outer baffle 230 along the air guide rib 240, so as to better improve the air flow outside the outer baffle 230, thereby improving the heat exchange efficiency inside the heat exchange box 200.

[0028] In order to further increase the distance of the airflow blown out from the mesh of the outer baffle 230 along the surface of the heat exchange box 200, so as to better remove the heat from the surface of the heat exchange box 200, in this embodiment, the air guide rib 240 extends downwardly at an angle away from the outer baffle 230. Since the airflow entering the heat exchange box 200 is generally in an upward flow direction, the airflow flowing out from the outer baffle 230 will also have an upward flow speed. At this time, the air guide rib 240 inclined downward can block the airflow flowing out from the outer baffle 230, increase the amount of airflow flowing along the air guide rib 240, and make the airflow flowing up and down along the air guide rib 240 cover a larger range, thereby better improving the air flow outside the outer baffle 230 and further improving the heat exchange efficiency of the heat exchange box 200.

[0029] The condenser can be directly loaded into the heat exchange box 200, and then the heat exchange box 200 is connected and fixed to the base 100. In order to facilitate the subsequent use and maintenance, in this embodiment, the outer baffle 230 is detachably connected to the base 100. When the condenser inside the heat exchange box 200 needs to be maintained, the outer baffle 230 can be removed to expose the condenser, which can improve the convenience of maintenance and replacement of the condenser and further improve the user experience.

[0030] A hole reserved for the installation of the outer baffle 230 can be directly opened on the top side of the base 100. When the outer baffle 230 and the base 100 are connected to each other, the bottom side of the outer baffle 230 can be directly plugged into the hole reserved on the base 100, so as to achieve a quick assembly connection between the two. In this embodiment, a connecting ring 250 is connected to the bottom side of the outer baffle 230, and a connecting groove is provided on the top side of the base 100. The connecting ring 250 is connected to the bottom side of the outer baffle 230. The connecting ring 250 can be used to strengthen the structural strength of the bottom side of the outer baffle 230, so that the outer baffle 230 is not easy to twist and deform. When the outer baffle 230 is installed on the base 100, the cooperation of the connecting ring 250 and the connecting groove can achieve a quick installation of the outer baffle 230 and the base 100, thereby improving the efficiency of the installation of the entire condensing unit. In actual applications, a plurality of through holes may be provided on the connecting ring 250 around the center line of the outer baffle 230. Correspondingly, a plurality of screw holes facing the through holes are provided on the bottom of the connecting groove. After the connecting ring 250 and the connecting groove are connected to each other, screws may be driven into the through holes, and the screws and the screw holes may be connected to each other, thereby further fastening the connecting ring 250 in the connecting groove.

[0031] The air discharged from the fan into the cavity will directly hit the inner top surface of the cavity, then spread out to the surroundings and flow to the connection between the heat exchange box 200 and the cavity. In order to better guide the airflow, in this embodiment, the inner top surface of the cavity is a conical surface with a larger top and a smaller bottom. When the fan is working, air enters from the air inlet 110, and then blows upward to the inner top surface of the cavity. Since the inner top surface of the cavity is a cone with a larger top and a smaller bottom, the wind blowing toward the inner top surface of the cavity can be guided and evenly flows into the heat exchange box 200 located outside the conical surface, which is conducive to evenly distributing the air discharged by the fan and improving the heat exchange efficiency of the condenser.

[0032] In some embodiments, a pulley 500 is connected to the bottom side of the base 100. When the whole needs to be moved, the whole can be conveniently moved through the pulley 500 on the bottom side of the base 100, thereby improving the convenience of overall use. In practical applications, the pulley 500 may be provided with a brake design. After the adjustment of the base 100 is completed, the pulley 500 may be locked and braked, thereby stably placing the base 100.

[0033] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
