Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, specifically to an assembled spiral radiator. Background Technology

[0002] An ice maker works by using the heat exchange effect of refrigerant to make ice. Therefore, it includes an evaporator and a radiator. The evaporator makes ice, and the radiator dissipates heat into the air, so that the refrigerant can circulate under the drive of the compressor.

[0003] Of course, in addition to ice makers, refrigerators, air conditioners, and other appliances also need radiators.

[0004] Radiators come in various structures, with finned radiators being a common type. These are manufactured by setting multiple heat dissipation fins. A more specific sub-category of finned radiators includes multiple fins arranged side-by-side and conduits that connect these fins. The conduits are welded to the fins. When refrigerant flows through the conduits, the fins dissipate the heat from the refrigerant. An example of this sub-category is an air-source heat pump radiator disclosed in CN105042680B. This air-source heat pump radiator includes: a shell, a heat transfer medium heat pipe, and an air-source heat pump. The heat transfer medium conduit has a disc-shaped structure and forms a circulation system with the air-source heat pump. Densely distributed heat dissipation fins are arranged around the heat transfer medium conduit, forming a heat dissipation core. The shell encloses the heat dissipation core and has ventilation holes on each surface of the shell. The hollow volume of the heat transfer medium conduit is matched with the power of the air-source heat pump to achieve optimal heat dissipation. This invention can make full use of heat energy directly and without loss, realizing the simplest, most thermally efficient, most energy-saving, and least space-consuming air source heat pump heating system. This invention does not need to be installed on or below the ground, is small in size and light in weight, and can be installed on a wall without affecting the aesthetics of the room, making it very simple and easy to implement.

[0005] This application further improves the aforementioned subdivided finned heat sink. As can be seen from the above, the prior art is constructed by setting through holes in the heat sink fins and inserting conduits through the through holes. In this way, on the one hand, the conduits and heat sink fins need to be further connected, and on the other hand, even if the conduits and heat sink fins are connected, it is not easy to make them tight. Furthermore, the process of inserting the conduits and heat sink fins is also relatively complicated. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an assembled spiral radiator that eliminates the through-hole structure, making manufacturing and assembly more convenient and simplifying the assembly work. In addition, the duct and the heat dissipation fins are designed as an integrated unit.

[0007] The technical solution of this utility model is: an assembled spiral radiator, including a metal conduit. The metal conduit consists of multiple straight pipes stacked in parallel from top to bottom. On the outer wall of each metal conduit, multiple spiral thin segments are arranged in sequence along the axis of the metal conduit. Each spiral thin segment is composed of a continuous spiral sheet extruded and formed on the outer wall of the metal conduit. The spiral sheet serves as a heat dissipation fin.

[0008] A U-shaped connecting tube is also provided on the same side of each group of adjacent metal conduits. The upper end of the U-shaped connecting tube is assembled and connected to the outlet of the upper metal conduit, and the lower end of the U-shaped connecting tube is assembled and connected to the inlet of the lower metal conduit, so that the metal conduits are assembled, connected and connected in sequence using the U-shaped connecting tube.

[0009] With the above structure, this utility model has the following advantages:

[0010] This disclosure improves upon existing designs by arranging multiple straight tubes, i.e., multiple straight metal conduits, in a sequential, parallel stack from top to bottom. Each metal conduit has multiple spiral thin segments arranged sequentially along its axial direction on its outer wall. Each spiral thin segment is composed of a continuous spiral sheet extruded onto the outer wall of the metal conduit, which serves as a heat dissipation fin. This makes manufacturing each metal conduit more convenient. Adjacent metal conduits are connected by separate U-shaped connecting tubes, allowing for independent manufacturing of the U-shaped connecting tubes. This eliminates the need for bending operations on-site when assembling the radiator, thus simplifying the assembly process. Furthermore, the conduits and heat dissipation fins are designed as a single unit.

[0011] In some embodiments, the upper end of the U-shaped connecting tube is sleeved and welded to the outlet of the upper metal conduit, and the lower end of the U-shaped connecting tube is sleeved and welded to the inlet of the lower metal conduit.

[0012] In some embodiments, the device further includes a bracket, which includes a frame and a receiving recess with through-ventilation holes formed by the frame. Various spiral thin segments are received and fitted in the receiving recess, and the frame is provided with a plurality of notches for mounting the ends of a straight tube and / or a U-shaped connecting tube.

[0013] In some embodiments, a fan is also included, which is connected to the frame to construct a sandwich structure to set the individual spiral thin segments.

[0014] In some embodiments, a first notch is provided on the frame, and a second notch corresponding to the first notch is provided on the fan. When the fan is connected to the frame, the first notch and the second notch cooperate to fix the light tube portion to indirectly support each spiral thin segment.

[0015] In some embodiments, each notch is configured as a semi-circular slot. Attached image description:

Detailed Implementation

[0028] To better understand this application, various aspects of this application will be described in more detail below with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0029] In the accompanying drawings, the thickness, size, and shape of the objects have been slightly exaggerated for illustrative purposes. The drawings are for illustrative purposes only and are not drawn to scale.

[0030] It should also be understood that the terms “comprising,” “including,” “having,” “containing,” “comprise,” and “containing”, when used in this specification, indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0031] like Figures 1 to 11 As shown, this disclosure proposes an assembled spiral radiator, including a metal conduit. The metal conduit consists of multiple straight pipes 3 arranged in parallel from top to bottom. Each metal conduit has multiple spiral thin segments 1 arranged in sequence along the axis of the metal conduit on its outer wall. Each spiral thin segment 1 is composed of a continuous spiral sheet 2 extruded and formed on the outer wall of the metal conduit. The spiral sheet 2 serves as a heat dissipation fin.

[0032] A U-shaped connecting pipe 15 is also provided on the same side of each group of adjacent metal conduits. The upper end of the U-shaped connecting pipe 15 is assembled and connected to the outlet of the upper metal conduit, and the lower end of the U-shaped connecting pipe 15 is assembled and connected to the inlet of the lower metal conduit, so that the metal conduits are assembled, connected and connected in sequence by using the U-shaped connecting pipe 15.

[0033] Based on their function, metal conduits are broadly classified into three types. The first type is the inlet section metal conduit, such as... Figure 1 As shown, the first type is the inlet metal conduit used to connect to the refrigerant; the second type is the intermediate metal conduit, such as... Figure 2 As shown, the intermediate section of the metal conduit is used to guide the refrigerant flow, and the third type is the outlet section of the metal conduit, such as... Figure 3 As shown, the outlet section metal conduit is used to discharge refrigerant. The inlet section metal conduit has the same main structure as the middle section metal conduit, the main difference being that its end away from the U-shaped connecting pipe 15 is open, so as to be connected to the refrigerant circulation system in the ice maker assembly and used as an inlet. The outlet section metal conduit has the same main structure as the middle section metal conduit, the main difference being that its end away from the U-shaped connecting pipe 15 is open, so as to be connected to the refrigerant circulation system in the ice maker assembly and used as an outlet.

[0034] To accommodate the layout of other components such as the evaporator and compressor, the inlet section metal conduit can be further welded or bent to form the inlet section 9, thus facilitating further connection during the assembly of the ice maker. Similarly, the outlet section metal conduit can be further welded or bent to form the outlet section 10, thus facilitating further connection during the assembly of the ice maker.

[0035] In some embodiments, in order to connect the U-shaped connecting pipe 15 more reliably, the upper end of the U-shaped connecting pipe 15 is sleeved and welded to the outlet of the upper metal conduit, and the lower end of the U-shaped connecting pipe 15 is sleeved and welded to the inlet of the lower metal conduit.

[0036] Of course, any structure that is suitable for the connection U-shaped connecting pipe 15 of this disclosure can be applied to this disclosure.

[0037] like Figure 5 As shown, in this example, a total of 6 spiral thin segments 1 are set, so 6 metal conduits need to be set. Each spiral thin segment 1 is composed of a spiral thin sheet 2, which is a continuous whole and is integrated with the outer wall of its respective metal conduit.

[0038] The spiral sheet 2 can be formed on the outer wall of the metal conduit by rotary rolling. Rotary rolling is an existing technology and will not be described in detail here.

[0039] In some embodiments, such as Figure 8 , 9 As shown in Figures 1 and 10, the system also includes a support frame, which includes a frame 4 and a recessed portion 6 formed by the frame 4 and having through-holes 5 for heat dissipation. Each spiral thin segment 1 is accommodated and fitted in the recessed portion 6. The frame 4 has multiple notches, each notch being used to install the two ends of the straight tube (3). In this way, the structure is simple and compact, easy to assemble, helps to reduce costs, and provides relatively reliable support.

[0040] If the length of the straight pipe 3 is short, the notch on one side of the U-shaped connecting pipe 15 can indirectly support the straight pipe (3) by supporting the U-shaped connecting pipe 15, which is beneficial to reduce the length of the radiator.

[0041] like Figure 9 As shown, the left end of the inlet section metal conduit is connected to a U-shaped connecting pipe 15. In order to shorten the inlet section metal conduit, the left end of the straight pipe (3) of the inlet section metal conduit is indirectly supported by the U-shaped connecting pipe 15 through the notch on one side of the U-shaped connecting pipe 15. The right end of the inlet section metal conduit is directly supported by the notch, which is beneficial to optimize the support.

[0042] Similarly, such as Figure 9As shown, the left end of the outlet section metal conduit is connected to a U-shaped connecting pipe 15. In order to shorten the outlet section metal conduit, the left end of the straight pipe (3) of the outlet section metal conduit is indirectly supported by the U-shaped connecting pipe 15 through the notch on one side of the U-shaped connecting pipe 15. The right end of the outlet section metal conduit is directly supported by the notch, which is beneficial to optimize the support.

[0043] The left and right ends of the intermediate metal conduit are indirectly supported by the corresponding support U-shaped connecting pipes 15.

[0044] In this example, as Figure 10 As shown, the frame 4 is a frame structure composed of four upright plates 13. The four upright plates 13 surround each other to form a receiving recess 6 with through heat dissipation holes 5, which is convenient to manufacture and helps to reduce costs.

[0045] To better support the individual spiral thin segments 1, a base plate 14 is also included as the bottom of the recess 6, which is connected to the four upright plates 13 to form a frame structure.

[0046] In some embodiments, such as Figure 11 As shown, it also includes a fan 7, which is connected to the frame 4 to construct a sandwich structure to set the various spiral thin segments 1, i.e., in Figure 9 The fan 7 is connected to the base to form a sandwich structure. In this way, the fan 7 also serves as the frame of this invention, which simplifies the structure and allows for a thinner design, which is significant for miniaturizing ice makers. Furthermore, it facilitates assembly and helps reduce costs.

[0047] In some embodiments, such as Figure 10 As shown, the frame 4 is provided with a first notch 8, and the fan 7 is provided with a second notch corresponding to the first notch 8. When the fan 7 is connected to the frame 4, the first notch 8 and the second notch cooperate to fix the two ends of the straight tube (3) and / or the U-shaped connecting tube 15 to support each spiral thin segment 1. In this way, it is further beneficial to simplify assembly and reduce costs.

[0048] To facilitate the connection of the fan 7 to the frame 4, a first connection hole 11 is provided on the base plate 14, and a second connection hole 12 is provided on the fan 7 at the position corresponding to the first connection hole 11. Fasteners are used to connect the fan 7 to the frame 4 through the first connection hole 11 and the second connection hole 12.

[0049] In some embodiments, such as Figure 10 As shown, each notch is designed as a semi-circular slot. This facilitates manufacturing and assembly, and helps reduce costs.

[0050] When understanding this utility model, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0051] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
