Technical Field

[0001] The invention relates to the technical field of evaporation, in particular to a double-circuit internally threaded copper tube fin evaporator. Background Art

[0002] Evaporation is the physical process of liquid to gas. Generally speaking, an evaporator is an object that converts liquid into gas. There are a large number of evaporators in the industry, of which the evaporator used in refrigeration systems is one of them. The evaporator is a very important component of the four major refrigeration components. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, gasify and absorb heat to achieve the refrigeration effect. The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0028] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0029] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to the attached Figure 1 -Attached Figure 8The present invention discloses a double-circuit internally threaded copper tube fin evaporator, comprising an evaporator body 1, the evaporator body 1 comprising an evaporation box 11, a refrigeration inlet pipe 12 and a refrigeration outlet pipe 13 connected to the left side of the evaporation box 11, and a double-circuit mechanism 2 connected to the lower end of the evaporation box 11, characterized in that the double-circuit mechanism 2 comprises a fluorine pump inlet pipe 201, a fluorine pump outlet pipe 203, a vertical copper tube 204, an inner sleeve 205, a translational sweeping plate 207, a push-out rod 208 and a sponge-like capillary structure block 209, the vertical copper tube 204 runs through the evaporation box 11, the upper end of the vertical copper tube 204 is connected to the fluorine pump outlet pipe 203, and the lower end of the vertical copper tube 204 is connected to the fluorine pump inlet pipe 201, The inside of the fluorine pump inlet pipe 201 is connected with an inner sleeve 205, and the outer wall of the inner sleeve 205 is provided with an external leakage hole 206. The lower end of the inner sleeve 205 extends to the outside of the fluorine pump inlet pipe 201 through the embedded pipe 202. The inner wall of the vertical copper tube 204 is an internal threaded circular tube structure, and the upper end of the inner wall of the vertical copper tube 204 is connected to the outer wall of the sponge-like capillary structure block 209. The inner wall of the fluorine pump outlet pipe 203 is connected to the translational sweeping plate 207 through the energy supply mechanism 3. The left and right sides of the translational sweeping plate 207 are provided with threaded holes, and the two threaded holes are not connected. The inner walls of the two threaded holes are spirally connected to the outer walls of the two push-out rods 208, and the two push-out rods 208 are arranged oppositely.

[0031] Collecting tubes are installed at the left and right ends of the fluorine pump outlet pipe 203, and the inner diameter of the collecting tube is larger than the closing plug 34. When the closing plug 34 is moved out of the fluorine pump outlet pipe 203, the extension frame 35 will enter the collecting tube. At this time, there is a gap between the closing plug 34 and the inner wall of the collecting tube, and the refrigerant will enter the collecting tube through the gap, so that the refrigerant can be easily reused after treatment.

[0032] The lower end of the embedded tube 202 is connected to the pressure-applying device, so that the pressure can be transmitted to the inner sleeve 205, so that the refrigerant flows out evenly from the small holes of the inner sleeve. At the same time, the inner wall of the embedded tube 202 and the fluorine pump inlet tube 201 will form a pressure equalization cavity, and the function of the pressure equalization cavity is to more evenly distribute the refrigerant into each vertical copper tube;

[0033] The inner wall of the vertical copper tube 204 is connected with a graphene plate, and the heat exchange capacity of the graphene can increase the heat exchange efficiency between the refrigerant and the copper tube.

[0035] Specifically, the fluorine pump inlet pipe 201 is used to transport refrigerant to the interior of the vertical copper tube 204 in the fluorine pump mode. The vertical copper tube 204 can make the refrigerant evaporate quickly from bottom to top in a full liquid state. At this time, the heated gas quickly flows out upward to the gas convergence end, and the copper tube liquid distribution in the entire evaporator is fuller, so that the refrigerant distribution in the evaporator is more uniform. The refrigerant in the fluorine pump outlet pipe 203 can be quickly discharged by the translational sweeping plate 207, and the refrigerant remaining on the upper wall of the fluorine pump outlet pipe 203 can also be scraped off. The sponge-like capillary structure block 209 can make the top of the vertical copper tube 204 have a siphon effect, so that the refrigerant overcomes the gravity and rises inside the vertical copper tube 204.

[0036] In the second embodiment, the energy supply mechanism 3 includes a mounting frame 31, a servo motor 32 and a screw rod 33. The right side of the upper end of the evaporation box 11 is connected to the lower end of the mounting frame 31, the upper end of the mounting frame 31 is detachably connected to the lower end of the servo motor 32, the left end of the servo motor 32 is detachably connected to the screw rod 33, and the screw rod 33 extends to the inside of the fluorine pump outlet pipe 203;

[0037] Through holes are provided at the left and right ends of the fluorine pump outlet pipe 203. The inner walls of the two through holes are slidably connected to the outer walls of the two closing plugs 34. The top walls of the two through holes are connected to the upper fixing plate 36. The upper end of the fluorine pump outlet pipe 203 is connected to the bayonet mechanism 4.

[0038] The two closing plugs 34 are connected to the extension frame 35 on the side close to each other, and the two extension frames 35 are connected to the ring rod plate 37 on the side close to each other. The ring rod plate 37 is arranged around the screw rod 33 and is slidably connected to the screw rod 33.

[0039] The ends of the two upper fixing plates 36 that are close to each other are connected to the closing springs 38 , and the ends of the two closing springs 38 that are close to each other are connected to the ring rod plate 37 .

[0040] Specifically, the closing of the fluorine pump outlet pipe 203 can be controlled by the closing plug 34, so that the refrigerant discharge speed becomes controllable, the screw rod 33 can drive the translational sweeping plate 207 to move, and the refrigerant on the upper wall of the fluorine pump outlet pipe 203 can be scraped off while pushing the refrigerant, so that the refrigerant can be quickly replenished and circulated, and the upper fixing plate 36 can be connected to the closing plug 34 through the extension frame 35, and the upper fixing plate 36 and the closing spring 38 can be used to give the closing plug 34 a reset function.

[0041] Embodiment 3, the bayonet mechanism 4 comprises a fixed plate 41 and a translation rod 42, the upper left side of the fluorine pump outlet pipe 203 is connected to the lower end of the fixed plate 41, and the left end of the fixed plate 41 is connected to the right end of the translation rod 42;

[0042] The bayonet mechanism 4 further comprises a bayonet translation frame 43, a lifting slot 44 is formed through the left end of the bayonet translation frame 43, the inner wall of the lifting slot 44 is slidably connected to the outer wall of the translation rod 42, and the lower end of the bayonet translation frame 43 is in contact with the outer wall of the fluorine pump outlet pipe 203;

[0043] The upper end of the fluorine pump outlet pipe 203 is connected with a rubber convex strip 45 , and the rubber convex strip 45 cooperates with the bayonet translation frame 43 .

[0044] Specifically, the fixing plate 41 and the translation rod 42 can provide an installation position for the bayonet translation frame 43, and the bayonet translation frame 43 can be used to clamp the removed closing plug 34, thereby temporarily fixing the position of the closing plug 34, and the rubber ridge 45 can increase the friction between the bayonet translation frame 43 and the fluorine pump outlet pipe 203, thereby improving the stability of the bayonet translation frame 43 when not in use, and the guide rod 46 can guide the translation of the translation sweeping plate 207, thereby making the translation of the translation sweeping plate 207 more stable.

[0045] Working principle:

[0046] First, start the evaporator 11. When the evaporator 11 is in the fluorine pump mode, the refrigerant will enter the fluorine pump inlet pipe 201 and the vertical copper tube 204 from the inner sleeve 205 due to pressure. Then, after use, the refrigerant will enter the fluorine pump outlet pipe 203 and be discharged. At this time, the servo motor 32 will be started synchronously, and the servo motor 32 will be used to drive the screw rod 33 to move, so that the translational sweeping plate 207 will move left and right with the push rod 208 inside the fluorine pump outlet pipe 203. At this time, the movement of the translational sweeping plate 207 will speed up the discharge speed of the refrigerant in the fluorine pump outlet pipe 203. At the same time, the translational sweeping plate 207 will scrape the residual refrigerant from the top wall of the fluorine pump outlet pipe 203, and the push rod 208 will move left and right to open the closed valve. The closing plug 34 is closed, thereby increasing the discharge speed of the refrigerant. When the thrust on the closing plug 34 is released, the closing plug 34 will be reset due to the action of the closing spring 38, thereby sealing the fluorine pump outlet pipe 203 again. When it is necessary to adjust the length of the push-out rod 208, the closing plug 34 on the corresponding side can be opened, and the push-out rod 208 can be moved out. At this time, the moving bayonet translation frame 43 can clamp the bayonet translation frame 43 between the closing plug 34 and the fluorine pump outlet pipe 203, thereby preventing the closing plug 34 from closing. Then the user can rotate the push-out rod 208. Because the push-out rod 208 is spirally connected to the translation sweep plate 207, the length of the push-out rod 208 can be adjusted when the push-out rod 208 rotates. At this point, the entire work process ends.
