Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to an evaporator with easily replaceable fins. Background Technology

[0002] The evaporator is a crucial component of the four main parts of a refrigeration system. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. The evaporator mainly consists of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat needed for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0003] An evaporator fin with publication number CN220454378U includes two heat-conducting tube sleeves. The inner wall of the heat-conducting tube sleeves is in contact with the outer wall of the evaporator tube. The two heat-conducting tube sleeves are detachably connected. The outer wall of the heat-conducting tube sleeves is provided with several heat dissipation mechanisms. The heat dissipation mechanism includes a copper column installed on the outer wall of the heat-conducting tube sleeves. Several heat dissipation fins are hinged to the outer wall of the copper column.

[0004] The device uses magnetic attraction to attach the two heat-conducting tube sleeves to the outer wall of the evaporator tube, thus enabling easy assembly and disassembly. However, the magnetic force will decrease after prolonged use, causing the heat-conducting tubes to fall off.

[0005] Meanwhile, the heat dissipation mechanism dissipates heat through copper pillars and heat sinks on the copper pillars. However, the heat sinks have a small heat dissipation area and poor heat dissipation effect. Furthermore, the air flows quickly within the evaporator, resulting in poor heat exchange.

[0006] Therefore, it is necessary to design an evaporator with easily replaceable fins to improve heat exchange efficiency. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an evaporator with easily replaceable fins, thereby solving the problems mentioned in the background section.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an evaporator with easily replaceable fins, comprising a shell, the shell comprising an upper substrate and a lower substrate arranged parallel to each other, a plurality of coils being disposed on the side of the lower substrate near the upper substrate, each coil having a set of fin assemblies sleeved on its outer side, each coil comprising a straight tube section and a curved tube section, the fin assembly comprising two semi-annular tubes wrapped around the outer wall of each straight tube section of the coil, each semi-annular tube having a plurality of fins fixedly connected to its outer wall, and two adjacent straight tube sections of the same coil and two semi-annular tubes on the same side having a common fin at both ends along the axial direction. A connecting plate is connected to the coil. A semi-circular pipe on the straight pipe section near the input and output ends of the coil is fixedly connected to a connecting plate to the side away from the adjacent straight pipe section via the connecting plate. The coil has fixing components on both sides along the length of the straight pipe section. Each fixing component includes two fixing blocks of the same shape and symmetrically arranged. Multiple grooves are formed on the two fixing blocks. When the two fixing blocks are fastened together, two grooves at the same position are merged to form a pipe. The pipe cooperates with the bend section of the coil. The fixing blocks have grooves, and the two ends of the connecting plate are located in the grooves along the length.

[0009] This utility model further illustrates that the coil is a continuous "S"-shaped tube, and several of the coils are linearly and uniformly arranged along the width direction of the lower substrate.

[0010] The present invention further describes that dustproof nets are provided on both sides of the lower substrate along the width direction, a liquid outlet pipe is provided inside the lower substrate, and the output ends of several coils are connected to the liquid outlet pipe. A liquid inlet pipe is provided inside the upper substrate, and the input ends of several coils are connected to the liquid inlet pipe.

[0011] The present invention further explains that the cross-sectional shape of the semi-ring pipe radially along the axis of the straight pipe section is a semi-circular ring, and the two semi-ring pipes are symmetrically arranged with the axis of the straight pipe section as the center, so that the two semi-ring pipes are joined together to wrap the straight pipe section of the coil.

[0012] This utility model further explains that two opposite connecting plates on the same coil interlock with each other, so that two symmetrical semi-ring pipes on the same straight pipe section are joined together to wrap the straight pipe section of the coil.

[0013] The present invention further describes that the fin is a semi-circular ring, the inner ring wall of the fin is fixedly connected to the outer wall of the semi-circular tube, the diameter of the outer ring wall of the fin is 1 mm smaller than the distance between two adjacent straight tube sections, and several fins are linearly and uniformly arranged along the axial direction of the semi-circular tube.

[0014] This utility model further illustrates that the fins on the two adjacent straight pipe sections are staggered, and the fins at the same horizontal height on the two adjacent coils are staggered.

[0015] The present invention further explains that the housing also includes two side base plates, which are respectively disposed at both ends of the lower base plate along the length direction. The two side base plates are symmetrically arranged. On the opposite side of the two side base plates, a plurality of grooves are provided for the fixing component. The fixing component is located in the grooves and cooperates with the grooves.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model achieves a detachable connection of the fin assembly by setting a fin assembly that is detachable from the coil and a fixing assembly that fixes the fin assembly and the coil.

[0017] By arranging the fins of the finned assemblies of two adjacent coils, the air can rotate multiple times within the cavity, thereby increasing the airflow resistance within the cavity and improving the heat exchange efficiency of the finned assemblies. Attached Figure Description

[0025] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 The present invention provides a technical solution: an evaporator with easy fin replacement, comprising a shell 1, the shell 1 comprising an upper substrate 2 and a lower substrate 3, the upper substrate 2 and the lower substrate 3 being arranged parallel to each other.

[0027] A cavity is provided inside the housing 1. Several coils 4 are provided on the side of the lower substrate 3 near the upper substrate 2. The coils 4 are located in the cavity and are continuous “S” shaped tubes. Several coils 4 are arranged linearly and uniformly along the width direction of the lower substrate 3.

[0028] A liquid outlet pipe 5 is provided inside the lower substrate 3, and the output ends of several coils 4 are connected to the liquid outlet pipe 5. A liquid inlet pipe 6 is provided inside the upper substrate 2, and the input ends of several coils 4 are connected to the liquid inlet pipe 6. Coolant flows inside the coils 4. After the liquid coolant enters the coils 4 through the liquid inlet pipe 6, it absorbs heat from the air in the cavity and vaporizes. Finally, it flows out of the coils 4 through the liquid outlet pipe 5, thereby cooling the air inside the housing 1.

[0029] The coil 4 includes a straight section 7 and a bend section 8, and each coil 4 is fitted with a set of finned assemblies 9 on its outer side.

[0030] The fin assembly 9 includes two semi-circular tubes 10 that wrap around the outer wall of each straight pipe section 7 of the coil 4. The semi-circular tubes 10 have a semi-circular cross-sectional shape along the radial direction of the axis of the straight pipe section 7. The two semi-circular tubes 10 are symmetrically arranged with the axis of the straight pipe section 7 as the center, so that the two semi-circular tubes 10 can wrap around the straight pipe section 7 of the coil 4 after being spliced ​​together.

[0031] Two adjacent straight pipe sections 7 of the same coil 4 and two semi-ring pipes 10 located on the same side are connected to a connecting plate 11 at both ends along the axial direction.

[0032] A semi-circular pipe 10 on a straight pipe section 7 near the input and output ends of the coil 4 is fixedly connected to a connecting plate 12 via a connecting plate 11 on the side away from the adjacent straight pipe section 7. The length direction of the connecting plate 12 is consistent with the length direction of the semi-circular pipe 10, and the connecting plate 12 is set vertically.

[0033] Two connecting plates 12 on the same coil 4 interlock with each other, so that two symmetrical semi-ring pipes 10 on the same straight pipe section 7 are joined together to wrap the straight pipe section 7 of the coil 4.

[0034] Several fins 13 are fixedly connected to the outer wall of each semi-annular tube 10. The fins 13 are semi-circular rings. The inner ring wall of the fins 13 is fixedly connected to the outer wall of the semi-annular tube 10. The diameter of the outer ring wall of the fins 13 is 1 mm smaller than the distance between two adjacent straight tube sections 7. Several fins 13 are linearly and uniformly arranged along the axial direction of the semi-annular tube 10.

[0035] The fins 13 on two adjacent straight pipe sections 7 are staggered, and the fins 13 at the same horizontal height on two adjacent coils 4 are staggered.

[0036] The coil 4 has fixing components on both sides along the length of the straight pipe section 7. The fixing components include two fixing blocks 14 with the same shape and symmetrical arrangement. Multiple grooves 15 are opened on the two fixing blocks 14. The two fixing blocks 14 are connected by bolts after they are interlocked.

[0037] After the two fixing blocks 14 are fastened together, the two grooves 15 at the same position are merged to form a pipe 16. The pipe 16 cooperates with the bend section 8 of the coil 4 and limits and fixes the bend section 8 of the coil 4 to prevent the coil 4 from shaking.

[0038] The fixing block 14 has a groove 17, and the two ends of the connecting plate 12 along the length direction are located in the groove 17. The groove 17 limits and fixes the connecting plate 12.

[0039] The housing 1 also includes two side base plates 18, which are respectively disposed at both ends of the lower base plate 3 along the length direction. The two side base plates 18 are symmetrically arranged. On the opposite side of the two side base plates 18, a number of grooves 19 are provided for the fixing component. The fixing component is located in the grooves 19 and cooperates with the grooves 19. The grooves 19 limit and fix the fixing component.

[0040] The lower substrate 3, the upper substrate 2, and the two side substrates 18 are detachably connected, which facilitates the disassembly and replacement of the fin assembly 9.

[0041] Dustproof mesh 20 is provided on both sides of the lower substrate 3 along the width direction to filter dust from the air entering the cavity and prevent dust from adhering to the fin assembly 9, which would reduce the heat exchange efficiency of the fin assembly 9.

[0042] In this embodiment, air enters the cavity through the dustproof net 20 on one side. Due to the staggered arrangement of the fins 13 on the two adjacent straight pipe sections 7 and the staggered arrangement of the fins 13 at the same horizontal height on the two adjacent coils 4, the air is diverted by the fin assemblies 9 on different coils 4 during its passage through the cavity. This increases the number of times the air rotates in the cavity, improves the heat exchange time of the air in the cavity, and does not affect the air flow rate, thereby improving the cooling effect of the air.

[0043] When one or more fin assemblies 9 on the coil 4 need to be replaced, after removing the upper base plate 2, remove the corresponding coil 4, the fixing components connected to the coil 4, and the fin assembly 9 from the groove 3 19, replace the fin assembly 9, and then reinstall it to complete the replacement of the fin assembly 9. The operation is simple and the replacement is convenient.
