For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] According to Figures 1 to 4 As shown in the figure, the condenser provided by the present application comprises a first support 10, a fin group 20 and a fan 30.

[0033] The fin group 20 is mounted on the first support 10, and the fin group 20 is in a cylindrical shape, and the inner diameter of the fin group 20 gradually decreases from the direction close to the first support 10 to the direction away from the first support 10.

[0034] The first support 10 has an air flow channel for connecting the external environment and the space surrounded by the fin group 20.

[0035] The fan 30 is mounted on the first support 10 and located in the direction close to the end of the fin group 20 with larger inner diameter.

[0036] The first support 10 is in a plate or block shape, and the first support 10 at least partially has a hollow area to form an air flow channel, so that air can enter the space surrounded by the fin group 20 through the air flow channel. The fin group 20 is mounted on the first support 10 by fixed connection (such as welding, bonding, fastener connection, etc.) or detachable connection.

[0037] The inner diameter of the fin group 20 gradually decreases from the direction close to the first support 10 to the direction away from the first support 10, forming a gradually tapered trumpet or cone structure.

[0038] For example Figure 1 As shown in the figure, the inner diameter of the fin group 20 gradually and uniformly decreases from the direction close to the first support 10 to the direction away from the first support 10, and the fin group 20 is in a conical cylindrical structure.

[0039] Preferably, the conical angle of the fin group 20 is 60°, and the inner diameter of the small end (i.e. the end with smaller inner diameter) of the fin group 20 is one third of the inner diameter of the large end (i.e. the end with larger inner diameter) of the fin group 20, so as to ensure that the heat exchange efficiency of the fin group 20 and air is optimal.

[0040] The fan 30 is installed on the first support 10 and located close to the large end of the fin group 20. The fan 30 is used to blow air flow to promote air convection and improve the heat dissipation effect of the fin group 20. When the fan 30 is running, air flow enters the space surrounded by the fin group 20 from the external environment through the air flow channel and flows from the large end of the fin group 20 to the small end of the fin group 20, so that the condensing fins far away from the fan 30 can also fully exchange heat with the air flow, effectively increasing the heat exchange area of the fin group 20. Optionally, the fan 30 is at least partially located in the space surrounded by the fin group 20.

[0041] Preferably, for example Figure 2 and Figure 3 As shown in the figure, in the normal working state of the condenser, the first support 10 is located above the fin group 20, and the inner diameter of the fin group 20 gradually decreases in the direction from top to bottom, which not only increases the heat exchange area of the fin group 20, but also prevents dust from accumulating on the condensing fins, avoiding the influence of dust on the contact between air and condensing fins.

[0042] The condenser provided by the application gradually reduces the inner diameter of the fin group 20 from the direction close to the first support 10 to the direction away from the first support 10, so that the fin group 20 has a tapered cylindrical structure. The fan 30 is located close to the end of the fin group 20 with a larger inner diameter, so that the air flow blown by the fan 30 blows from the large end of the fin group 20 to the small end of the fin group 20, so that the air flow fully contacts the fin group 20, greatly increasing the heat exchange area of the fin group 20, facilitating the contact between air and the fin group 20 for heat exchange, and improving the heat exchange efficiency of the condenser.

[0043] Specifically, the fin group 20 includes a condensing pipe and condensing fins, the condensing pipe is surrounded by a tapered cylinder, the condensing pipe penetrates through the plurality of condensing fins, and the plurality of condensing fins are distributed around the central axis of the condensing pipe.

[0044] The condensing pipe is used as a flow channel for refrigerant, the condensing pipe is surrounded by a tapered cylinder with two open ends, the plurality of condensing fins are vertically arranged around the condensing pipe at intervals, and the angle between each condensing fin and the central axis of the condensing pipe is the same.

[0045] Further, the condenser further comprises a second support 40, and the end of the fin group 20 away from the first support 10 is installed on the second support 40.

[0046] The second support 40 is in the form of a plate or a block, and the fin group 20 is installed on the second support 40 by fixed connection (such as welding, bonding, fastener connection, etc.) or detachable connection. For example Figure 2As shown, the second support 40 serves as a base of the fin group 20, facilitating the installation and disassembly of the condenser. The first support 10 and the second support 40 are respectively located at two ends of the fin group 20, playing a role of supporting and protecting the fin group 20.

[0047] Further, the condenser further comprises a positioning assembly 50 connected to the first support 10 and the second support 40 respectively.

[0048] The positioning assembly 50 is used to connect and fix the first support 10 and the second support 40, and facilitates the positioning and installation of the first support 10 and the second support 40. By providing the positioning assembly 50, the stability of the connection between the first support 10 and the second support 40 is enhanced, preventing the relative movement of the first support 10 and the second support 40 and affecting the stability of the condenser.

[0049] In an alternative embodiment, the positioning assembly comprises a positioning column or a positioning plate, and the first support 10 and the second support 40 are respectively provided with a positioning slot. By inserting the two ends of the positioning column or the positioning plate into the positioning slot, the positioning and installation and the connection and fixation of the first support 10 and the second support 40 are achieved.

[0050] Further, the positioning assembly 50 is multiple, and the multiple positioning assemblies 50 are distributed along the circumference of the fin group 20.

[0051] On the one hand, by providing multiple positioning assemblies 50, the positioning and fixing effect of the first support 10 and the second support 40 is enhanced. On the other hand, the multiple positioning assemblies 50 are distributed along the circumference of the fin group 20 with gaps between them, which can avoid affecting the circulation of air and ensure the heat exchange effect of the fin group 20.

[0052] Specifically, the positioning assembly 50 comprises a first sleeve 51, a second sleeve 52 and a support rod 53. The first sleeve 51 is arranged on the first support 10, the second sleeve 52 is arranged on the second support 40, the first end of the support rod 53 is inserted into the first sleeve 51, and the second end of the support rod 53 is inserted into the second sleeve 52.

[0053] The first sleeve 51 can be of an integral structure with the first support 10, or can be fixed to the first support 10 by welding, bonding or the like. The second sleeve 52 can be of an integral structure with the second support 40, or can be fixed to the second support 40 by welding, bonding or the like.

[0054] Specifically, the positioning assembly 50 is multiple, the first support 10 is provided with multiple first sleeves 51, the second support 40 is correspondingly provided with multiple second sleeves 52, and multiple support rods 53 are correspondingly inserted into the first sleeves 51 and the second sleeves 52.

[0055] Preferably, the plurality of positioning assemblies 50 are evenly distributed in the circumferential direction of the fin group 20 to improve the positioning and fixing effect of the first support 10 and the second support 40.

[0056] Further, the first sleeve 51 and the second sleeve 52 are both internally threaded, and the two ends of the support rod 53 are provided with threaded portions adapted to the internal threads, and the support rod 53 is threadedly connected with the first sleeve 51 and the second sleeve 52 respectively.

[0057] As shown in Figure 2 the two ends of the support rod 53 are screwed into the first sleeve 51 and the second sleeve 52 respectively, and the threaded connection enhances the connection stability of the support rod 53 with the first sleeve 51 and the second sleeve 52, preventing the support rod 53 from coming out of the first sleeve 51 or the second sleeve 52.

[0058] Further, the condenser further comprises a first limiting piece 60 and a second limiting piece 70, the first limiting piece 60 is installed on the first support 10, and the second limiting piece 70 is installed on the second support 40.

[0059] The first limiting piece 60 is provided with a first mounting slot, and the second limiting piece 70 is provided with a second mounting slot, and a flexible piece 61 is arranged in the first mounting slot and the second mounting slot, one end of the fin group 20 is embedded in the first mounting slot, and the other end of the fin group 20 is embedded in the second mounting slot.

[0060] By arranging the first limiting piece 60 and the second limiting piece 70, the fin group 20 is installed in the first mounting slot and the second mounting slot, which improves the installation reliability of the fin group 20 and enhances the connection stability of the fin group 20 with the first support 10 and the second support.

[0061] The first limiting piece 60 can be an integral structure with the first support 10, or can be fixed to the first support 10 by welding, bonding or other methods; the second limiting piece 70 can be an integral structure with the second support 40, or can be fixed to the second support 40 by welding, bonding or other methods.

[0062] Among them, the first limiting piece 60 and the second limiting piece 70 can be plate-shaped, block-shaped or ring-shaped, for example Figure 2 As shown in the figure, the first limiting piece 60 and the second limiting piece 70 are both ring-shaped, and air can flow smoothly and unobstructed through the hollow part of the first limiting piece 60, and the hollow part of the first limiting ring 0 provides installation space for the fan 30.

[0063] In this embodiment, the first mounting groove is annularly arranged on the annular region of the first limiting member 60, and the second mounting groove is annularly arranged on the annular region of the second limiting member 70. The shapes of the first mounting groove and the second mounting groove are adapted to the shape of the end of the fin group 20, so that the end of the fin group 20 can be closely attached to the first mounting groove or the second mounting groove, and the fin group 20 is prevented from shaking.

[0064] For example Figure 4 As shown in the figure, the cross section of the first mounting groove and the second mounting groove is in the shape of a "H" character, and the inclination angle and the groove width of the first mounting groove and the second mounting groove are respectively adapted to the end of the fin group 20.

[0065] The flexible member 61 is made of flexible materials such as silica gel, rubber, and foamed plastic, and has the effect of buffering and protecting the end of the fin group 20. For example Figure 4 As shown in the figure, the flexible member 61 is in the shape of a circular ring and is attached to the inner wall surface of the first mounting groove and the second mounting groove, and the cross section of the flexible member 61 is in the shape of a "H" character. The flexible member 61 can fully cover the end of the fin group 20, reduce the impact on the fin group 20, and prevent the fin group 20 from being damaged by knocking during installation.

[0066] The condenser provided by the application is provided with an air flow passage and a filter assembly. The filter assembly is used to filter the air entering the space surrounded by the fin group 20, reduce the contact between dust and the fin group 20, and keep the surface of the fin group clean.

[0067] Further, the filter assembly includes a plurality of filter members 131. For example Figure 2 and Figure 4 As shown in the figure, the filter assembly includes four filter members 131.

[0068] The first support member is provided with a stepped hole 11 having a plurality of steps. The surface area of the plurality of steps gradually decreases along the direction from the first support member 10 to the fin group 20, and the filter member 131 is installed on the steps. For example Figure 4 As shown in the figure, the stepped hole 11 has four steps.

[0069] Specifically, the filter member 131 can be a filter screen plate, which is beneficial to filtering dust and other dirt. Preferably, along the direction from the first support member 10 to the fin group 20, the apertures of the filter member 131 gradually decrease, and the filtering capacity of the filter member 131 gradually increases, which is beneficial to filtering dust and other dirt from weak to strong along the flow direction of the air flow, and improves the filtering effect of the filter assembly.

[0070] The plurality of steps are sequentially distributed along the direction from the first support member 10 to the fin group 20, and the top surface of the steps is used to install the filter member 131.

[0071] Specifically, the diameters of the plurality of steps gradually decrease along a direction from the first support 10 to the fin group 20, and the sizes of the filter pieces 131 to be installed also gradually decrease. Figure 2 Figure 2 As shown, by arranging the stepped holes 11, the filter pieces 131 can be installed from bottom to top in sequence, which facilitates quick and flexible disassembly and assembly of the filter pieces 131, and also facilitates flexible arrangement of the sizes and quantities of the filter pieces according to actual requirements.

[0072] The filter piece 131 can be installed on the step by means of adhesion, clamping or the like.
