Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an evaporator with a double-walled heat shrink tubing structure. Background Technology

[0002] The evaporator is a very important component among the four major refrigeration components. Low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, vaporizing and absorbing heat to achieve the cooling effect.

[0003] In existing technology, when using an evaporator, external pipes need to be connected to the heat exchange tubes of the evaporator through flanges and flanges. However, the flanges of the evaporator can only be connected to flanges of a fixed size, and cannot be matched with flanges of different sizes, which reduces the practicality of the evaporator. Utility Model Content

[0004] This utility model proposes an evaporator with a double-walled heat shrink tubing structure to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an evaporator with a double-walled heat shrink tubing structure, comprising an evaporator shell, four support legs installed at the bottom of the evaporator shell, wherein the evaporator shell is supported by the support legs on a mechanical surface, the heat exchange tube is embedded inside the evaporator shell, wherein the heat exchange tube has a serpentine cross-section, the heat shrink tubing is fixedly connected to both ends of the heat exchange tube, the heat shrink tubing consists of an inner wall and an outer wall, wherein the inner wall of the heat shrink tubing is made of hot melt adhesive, and the outer wall of the heat shrink tubing is made of cross-linked polyolefin material, the flange is fixedly connected to one end of the heat shrink tubing, and the flange can be connected to external pipes of different widths by means of a fixing device.

[0006] The effects achieved by the above components are as follows: When using the evaporator shell, the operator first connects the external pipe to the flange of the heat shrink tubing using a fixing device. The hot melt adhesive inside the heat shrink tubing melts when heated and fills the gaps, preventing condensate from flowing out. The cross-linked polyolefin material on the outside of the heat shrink tubing improves its wear resistance and extends its service life. When the evaporator shell is working, the external pipe sends the condensate through the heat shrink tubing into the interior of the heat exchange tube. The heat exchange tube exchanges heat with the condensate, thereby achieving the cooling effect.

[0007] Preferably, the fixing device includes a plurality of first reserved holes and second reserved holes. The plurality of first reserved holes are circumferentially distributed on the surface of the flange, and the plurality of second reserved holes are circumferentially distributed on the surface of the flange. The first reserved holes are enclosed by the second reserved holes. The fixing ring is fitted onto the arc surface of the heat shrink tubing. A rubber plug is fixedly connected to the fixing ring at the position corresponding to the first reserved hole. The size of the rubber plug is adapted to the size of the first reserved hole. The L-shaped plate is fixedly connected to the arc surface of the flange. The insert plate slides through the surface of the L-shaped plate. An insertion hole is provided at the position corresponding to the L-shaped plate. The size of the insert plate is adapted to the size of the insertion hole.

[0008] The aforementioned components achieve the following effects: When connecting smaller external pipes, the screws of the flange pass through the first pre-drilled hole of the flange to connect the flange and the flange, thus completing the installation of the external pipe. When connecting larger external pipes, the screws of the flange pass through the second pre-drilled hole of the flange to connect the flange and the flange, thus completing the connection of the external pipe. At this point, the operator moves the fixing ring, and the rubber plug on the fixing ring is inserted into the first pre-drilled hole, blocking the first pre-drilled hole. Finally, the operator moves the insert plate on the L-shaped plate, and the insert plate is inserted into the insertion hole of the fixing ring, achieving the effect of fixing the fixing ring and preventing the rubber plug from moving out of the first pre-drilled hole under the pressure of the condensate. Through the fixing device, the connection of external pipes of different specifications is achieved, thereby improving the practicality of the evaporator shell.

[0009] Preferably, one end of the insert plate is fixedly connected to a pointed protrusion, the tip of which is away from the insert plate.

[0010] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the insert plate into the hole of the fixing ring, thus providing convenience for workers.

[0011] Preferably, the arc surface of the heat shrink tubing is fixedly connected with a plurality of limiting members, and the plurality of limiting members are distributed in a circle.

[0012] The effect achieved by the above components is that by setting the limiting component, the movement direction of the fixed ring is restricted, thus preventing rotation between the fixed ring and the heat shrink tubing.

[0013] Preferably, a handle is fixedly connected to one side of the fixing ring, and the surface of the handle is provided with anti-slip texture.

[0014] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the fixed ring by setting a handle, thereby making it easier for the worker to move the fixed ring.

[0015] Preferably, the bottom of the support leg is provided with an auxiliary device, the auxiliary device including a bolt, the bolt being disposed above the support leg, a rectangular hole being formed on the surface of the support leg, wherein the bolt can pass through the rectangular hole, and a cap is fixedly connected to one end of the bolt, wherein the size of the cap is larger than the size of the rectangular hole.

[0016] The aforementioned components achieve the following effects: when the evaporator housing needs to be installed, the evaporator housing is moved to a suitable location, and then the operator moves the bolts, which pass through the rectangular holes of the support legs and are inserted into the pre-drilled mounting holes in the machine. Finally, the cap is placed against the upper surface of the support legs, thus securing the support legs and the evaporator housing. The auxiliary device achieves the effect of securing the evaporator housing, and at the same time, it facilitates the disassembly of the evaporator housing by the operator when it is damaged.

[0017] Preferably, a pull rope is fixedly connected to one side of the cap, wherein one end of the pull rope is fixedly connected to the support leg.

[0018] The effect achieved by the above components is that by setting up a pull rope, the maximum displacement of the bolt is limited, thus preventing the bolt from falling off when not in use.

[0019] Preferably, two rubber pads are fixedly connected to the upper surface of the support leg, with the two rubber pads located on both sides of the rectangular hole respectively.

[0020] The effect achieved by the above components is to increase the friction between the cap and the legs by setting rubber pads, thereby preventing the cap and legs from shaking.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When connecting smaller external pipes to the flange, the flange bolts pass through the first pre-drilled hole of the flange to connect the flange and the flange, thus completing the installation of the external pipe. When connecting larger external pipes to the flange, the flange bolts pass through the second pre-drilled hole of the flange to connect the flange and the flange, thus completing the connection of the external pipe. At this time, the worker moves the fixing ring, and the rubber plug on the fixing ring is inserted into the first pre-drilled hole to block the first pre-drilled hole. Finally, the worker moves the insert plate on the L-shaped plate, and the insert plate is inserted into the insertion hole of the fixing ring, achieving the effect of fixing the fixing ring. This prevents the rubber plug from moving out of the first pre-drilled hole under the pressure of the condensate liquid. The fixing device achieves the effect of connecting external pipes of different specifications, thereby improving the practicality of the evaporator shell. Attached Figure Description

When using the evaporator housing 1, the operator first connects the external pipe to the flange 5 of the heat shrink tubing 4 using the fixing device 6. The hot melt adhesive inside the heat shrink tubing 4 melts when heated and fills the gaps to prevent condensate from flowing out. The cross-linked polyolefin material on the outside of the heat shrink tubing 4 improves its wear resistance and extends its service life. When the evaporator housing 1 is working, the external pipe sends the condensate through the heat shrink tubing 4 into the interior of the heat exchange tube 2. The heat exchange tube 2 exchanges heat with the condensate, thereby achieving the cooling effect.

[0029] Reference Figure 1-4As shown, the fixing device 6 includes several first reserved holes 61 and second reserved holes 62. The several first reserved holes 61 are circumferentially distributed on the surface of the flange 5, and the several second reserved holes 62 are circumferentially distributed on the surface of the flange 5, wherein the first reserved holes 61 are surrounded by the second reserved holes 62; a fixing ring 63 is fitted onto the arc surface of the heat shrink tubing 4, and a rubber plug 64 is fixedly connected to the fixing ring 63 at the position corresponding to the first reserved hole 61, wherein the size of the rubber plug 64 is adapted to the size of the first reserved hole 61; an L-shaped plate 65 and an insert plate 66 are provided. The L-shaped plate 65 is fixedly connected to the arc surface of the flange 5, and the insert plate 66 slides through the surface of the L-shaped plate 65. The fixing ring 63 has an insertion hole 67 at the position corresponding to the L-shaped plate 65, wherein the size of the insert plate 66 is adapted to the size of the insertion hole 67. When connecting smaller external pipes, the screws of the flange pass through the first reserved hole 61 of the flange 5 to connect the flange and the flange 5, thus completing the installation of the external pipe. When connecting larger external pipes, the screws of the flange pass through the second reserved hole 62 of the flange 5 to connect the flange and the flange 5, thus completing the connection of the external pipe. At this time, the operator moves the fixing ring 63, and the rubber plug 64 on the fixing ring 63 is inserted into the first reserved hole 61 to block the first reserved hole 61. Finally, the operator moves the insert plate 66 on the L-shaped plate 65, and the insert plate 66 is inserted into the insertion hole 67 of the fixing ring 63, thus achieving the effect of fixing the fixing ring 63 and preventing the rubber plug 64 from moving out of the first reserved hole 61 under the pressure of the condensate. The fixing device 6 achieves the effect of connecting external pipes of different specifications, thereby improving the practicality of the evaporator shell 1.

[0030] Reference Figure 1-4 As shown, a pointed protrusion 610 is fixedly connected to one end of the insert plate 66, with the tip of the protrusion 610 away from the insert plate 66. The pointed protrusion 610 facilitates the insertion of the insert plate 66 into the insertion hole 67 of the fixing ring 63, providing convenience for the operator. Several limiting members 68 are fixedly connected to the arc surface of the heat shrink tubing 4, and these limiting members 68 are circumferentially distributed. The limiting members 68 restrict the movement direction of the fixing ring 63, preventing rotation between the fixing ring 63 and the heat shrink tubing 4. A handle 69 is fixedly connected to one side of the fixing ring 63, and the surface of the handle 69 has anti-slip texture. The handle 69 increases the contact area between the operator's hand and the fixing ring 63, thus facilitating the movement of the fixing ring 63.

[0031] Reference Figure 1-4As shown, the bottom of the support leg 3 is equipped with an auxiliary device 7, which includes a bolt 71. The bolt 71 is positioned above the support leg 3, and a rectangular hole 73 is formed on the surface of the support leg 3, through which the bolt 71 can pass. One end of the bolt 71 is fixedly connected to a cap 72, the size of which is larger than the size of the rectangular hole 73. When it is necessary to install the evaporator housing 1, the evaporator housing 1 is moved to a suitable location. Then, the operator moves the bolt 71, which passes through the rectangular hole 73 of the support leg 3 and is inserted into the pre-drilled mounting hole. Finally, the cap 72 rests against the upper surface of the support leg 3, thus achieving the effect of fixing the support leg 3 and the evaporator housing 1. The auxiliary device 7 achieves the effect of fixing the evaporator housing 1 and also facilitates the disassembly of the evaporator housing 1 if it is damaged.

[0032] Reference Figure 1-4 As shown, a pull rope 75 is fixedly connected to one side of the cap 72, with one end of the pull rope 75 fixedly connected to the support leg 3. The pull rope 75 limits the maximum displacement of the bolt 71, preventing it from falling off when not in use. Two rubber pads 74 are fixedly connected to the upper surface of the support leg 3, located on either side of the rectangular hole 73. The rubber pads 74 increase the friction between the cap 72 and the support leg 3, preventing them from wobbling.

[0033] Working principle: When connecting a smaller external pipe flange, the flange bolts pass through the first reserved hole 61 of the flange 5 to connect the flange and flange 5, thus completing the installation of the external pipe. When connecting a larger external pipe flange, the flange bolts pass through the second reserved hole 62 of the flange 5 to connect the flange and flange 5, thus completing the connection of the external pipe. At this time, the operator moves the fixing ring 63 by the handle 69. The limiting piece 68 on the heat shrink tubing 4 achieves the effect of restricting the movement direction of the fixing ring 63. The rubber plug 64 on the fixing ring 63 is inserted into the first reserved hole 61 to block the first reserved hole 61. Finally, the operator moves the insert plate 66 on the L-shaped plate 65. The insert plate 66, with its pointed protrusion... Inserting the 610 into the insertion hole 67 of the fixing ring 63 achieves the effect of fixing the fixing ring 63, preventing the rubber plug 64 from moving out of the first reserved hole 61 under the pressure of the condensate. The hot melt adhesive inside the heat shrink tubing 4 melts when heated and can fill the gap, preventing the condensate from flowing out. The cross-linked polyolefin material on the outside of the heat shrink tubing 4 improves the wear resistance of the heat shrink tubing 4 and increases its service life. When the evaporator shell 1 is working, the external pipe sends the condensate into the interior of the heat exchange tube 2 through the heat shrink tubing 4. The heat exchange tube 2 exchanges heat with the condensate, thereby completing the cooling effect. The fixing device 6 achieves the effect of connecting external pipes of different specifications, thereby improving the practicality of the evaporator shell 1.

[0034] When it is necessary to install the evaporator housing 1, the evaporator housing 1 is moved to a suitable position. Then, the operator moves the bolt 71, which passes through the rectangular hole 73 of the support leg 3 and is inserted into the pre-drilled mounting hole. Finally, the cap 72 is placed against the rubber pad 74 of the support leg 3, thus fixing the support leg 3 and the evaporator housing 1. The auxiliary device 7 is used to fix the evaporator housing 1 and also facilitates the operator to disassemble the evaporator housing 1 if it is damaged.
