Description

Technical Field

[0001] The invention relates to the technical field of evaporators, in particular to a cold storage type evaporator for an electric vehicle. Background Art

[0002] The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification in the car compartment. It is one of the indicators to measure whether the car functions are complete. The evaporator is a key component in the automobile air conditioning unit. Its structure, material properties and manufacturing process affect the working efficiency of the entire air conditioning system. Its working principle is to use evaporation to absorb heat and thus cool down. When the low-temperature and low-pressure liquid refrigerant passes through the evaporator, the liquid refrigerant vaporizes and absorbs the heat in the car compartment, thereby quickly cooling the car compartment.

[0003] When the existing evaporator is in use, when the car stops and the compressor stops working, the refrigerant in the evaporator no longer flows, so the air outlet of the car air conditioner no longer discharges cold air. Since the car may encounter traffic jams during driving, turning on the air conditioner for a long time will consume a lot of energy. Especially for electric cars, since the battery life will become worse and worse, turning on the air conditioner for a long time will greatly affect the battery life. Therefore, most drivers will turn off the air conditioner to save power. However, turning off the air conditioner will cause the cold air in the car to dissipate faster, which will cause the temperature in the small space of the car to rise faster, which will make the occupants feel very uncomfortable, seriously affecting the riding experience of the occupants. Summary of the invention

[0004] The object of the present invention is to provide a cold storage evaporator for an electric vehicle to solve the problems raised in the above background technology.

An air inlet pipe is fixed through one end of the interior of the air storage tank, and a connecting pipe fixedly connected to the interior of one of the annular shells is fixed through the other end of the interior of the air storage tank. A storage mechanism is arranged inside the gas storage tank and is used for storing and releasing refrigerant. The storage mechanism includes a moving component, and a sealing component is slidably connected to the outer side of the moving component. The moving component includes two symmetrical fixed nets that are respectively fixedly connected to the two ends of the gas storage tank, and a round rod is rotatably connected between the two fixed nets. A moving block is slidably connected to the outer wall of the round rod, and a side surface of the moving block is provided with a plurality of air outlet holes at equal angles in an annular manner. The sealing component includes a plurality of blocking blocks distributed in an annular manner at equal angles, and a plurality of through holes are slidably opened on one side surface of the blocking block. Two symmetrical connecting rods that slide through the moving block are fixedly connected to one side surface of the blocking block; The cleaning mechanism is arranged at the inner bottom of the fixing seat and is used for cleaning the dust adsorbed on the outer sides of the plurality of flat tubes.

[0006] Furthermore, a circular ring is fixedly connected to one side of the two fixed nets opposite to each other and located on the outside of the round rod, a clockwork spring is fixedly connected to the outer wall of the round rod, one end of the clockwork spring is fixedly connected to the inner wall of the circular ring at the corresponding position, a spiral groove is opened on the outer wall of the round rod, a sleeve that slides through the round rod is fixed on one side of the moving block, and a ball that slides in the spiral groove is fixedly connected to the inner wall of the sleeve.

[0007] Furthermore, two symmetrical limiting rods are fixedly connected between the two fixed nets and slide through the moving block.

[0008] Furthermore, circular grooves are provided on both sides of the air outlet at the corresponding position on one side of the moving block, and a compression spring fixedly connected to the inner bottom surface of the circular groove at the corresponding position is fixedly connected to the circular groove on one side of the blocking block.

[0009] Furthermore, a sealing gasket is fixedly connected to a side of the blocking block opposite to the moving block.

[0010] Furthermore, a magnetic ring 1 is embedded and fixed on one side of the fixed net away from the air inlet pipe, a connecting ring is fixedly connected between one ends of the plurality of connecting rods, and a magnetic ring 2 attracted to the magnetic ring 1 is embedded and fixed on one side of the connecting ring.

[0011] Furthermore, the outer wall of the connecting rod is provided with two symmetrical spherical grooves, a fixed frame is fixedly connected to a side surface of the moving block corresponding to the connecting rod, cylindrical sleeves are penetrated and fixed on two opposite sides of the fixed frame, and a spring steel ball that is clamped with the spherical groove at the corresponding position is fixedly connected inside the cylindrical sleeve.

[0012] Furthermore, the outer wall of the annular shell is fixedly connected to a fixing ring which is rotatably connected to a fixing seat and is fixedly penetrated by a connecting pipe, and the ends of the air inlet pipe and the air outlet pipe are fixedly connected to a rotating joint, and the center of the rotating joint is located on the same straight line as the center of the air storage tank and the annular shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The moving block can be moved by pouring refrigerant into the gas storage tank, so that the refrigerant can be stored. When the refrigerant moves to contact the fixed net far away from the air inlet pipe, the blocking block separates from the moving block to open the air outlet so that the refrigerant can flow normally into the multiple flat tubes, thereby achieving normal cooling. When the compressor stops, the moving block moves in the opposite direction, and the blocking block blocks the air outlet at the corresponding position, which can slow down the flow rate of the refrigerant stored in the gas storage tank, thereby extending the cooling time of the air conditioner. The wind generated by starting the external blower drives the multiple flat tubes to rotate, which can throw out the condensed water adsorbed on the surface of the flat tubes, preventing the condensed water from being adsorbed on the flat tubes for a long time, thereby reducing the growth of bacteria, which is of great benefit to the health of the driver and passengers in the car; The rotation of the annular shell can make the two reciprocating screws and the annular brush rotate along the axis of the annular shell. Since the ring gear is engaged with the two gears, the reciprocating screw rotating along the axis of the annular shell rotates under the action of the gear and the ring gear. The rotating reciprocating screw can make the annular brush reciprocate in the fixed seat, thereby cleaning the dust adsorbed on the surfaces of multiple flat tubes and avoiding the problem of poor cooling effect due to dust obstruction.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 10In an embodiment of the present invention, a cold storage evaporator for an electric vehicle comprises a fixing seat 1, a gas storage tank 2, a storage mechanism 3, and a cleaning mechanism 4. The fixing seat 1 is installed and fixed in the evaporation box of the automobile. An annular shell 11 is rotatably penetrated on both opposite sides of the fixing seat 1. A plurality of flat tubes 13 are fixedly connected at equal angles in an annular manner between opposite sides of the two annular shells 11. The flat tubes 13 are connected to the interior of the two annular shells 11. An air outlet pipe 14 is fixedly penetrated in the interior of one of the annular shells 11. The gas storage tank 2 is fixedly penetrated between the two annular shells 11 for storing refrigerant. An air inlet pipe 21 is fixedly penetrated at one end of the interior of the gas storage tank 2. A connecting pipe 22 fixedly connected to the interior of one of the annular shells 11 is fixedly penetrated at the other end of the interior of the gas storage tank 2. The storage mechanism 3 is arranged in the interior of the gas storage tank 2 for storing refrigerant. The storage mechanism 3 comprises a moving component 31, and a sealing component 32 is slidably connected to the outer side of the moving component 31. The moving component 31 comprises two symmetrical fixed nets 311 respectively fixedly connected to the two ends of the gas storage tank 2. A round rod 312 is rotatably connected between the two fixed nets 311. A moving block 313 is slidably connected to the outer wall of the round rod 312. A side surface of the moving block 313 is provided with a plurality of air outlet holes 314 at equal angles in an annular shape. The sealing component 32 comprises a plurality of blocking blocks 321 distributed in an annular shape at equal angles. A plurality of through holes 3211 are slidably opened on one side surface of the blocking block 321. Two symmetrical connecting rods 322 slidably penetrated with the moving block 313 are fixedly connected to one side surface of the blocking block 321. The cleaning mechanism 4 is arranged at the inner bottom of the fixed seat 1, and is used to clean up the dust adsorbed on the outer sides of the plurality of flat tubes 13.

[0020] Specifically, firstly, the fixing seat 1 is installed and fixed in the evaporator box of the automobile, and the air inlet pipe 21 is connected to the expansion valve, and the air outlet pipe 14 is connected to the compressor. When the compressor is working, the refrigerant can be pressed into the gas storage tank 2 from the air inlet pipe 21 through the condenser and the expansion valve. Since the refrigerant pressed into the gas storage tank 2 is restricted by the moving block 313, and the plurality of blocking blocks 321 respectively block the air outlet holes 314 at the corresponding positions, the continuously injected refrigerant will increase the pressure in the gas storage tank 2 between the moving block 313 and the air inlet pipe 21, thereby pushing the moving block 313 to move away from the air inlet pipe 21 (the moving block 313 is similar to the piston of a syringe). Since a plurality of through holes 3211 are opened through the side of the blocking block 321, a part of the refrigerant will be The refrigerant is poured into the two annular shells 11 and the multiple flat tubes 13 through the multiple through holes 3211 and the connecting pipes 22, and then the cold air generated by the refrigerant in the multiple flat tubes 13 can be blown out through an external blower (due to the relatively small diameter of the through holes 3211, the pressure in the gas storage tank 2 between the moving block 313 and the air inlet pipe 21 will still increase. Although the flow rate of the refrigerant passing through the through holes 3211 per unit time is relatively small, cold air can still be blown out, but the temperature of the cold air will be relatively higher). When the multiple connecting rods 322 move to contact the fixed net 311 in the moving direction and the pressure in the gas storage tank 2 is still increasing, the multiple connecting rods 322 will be subjected to a reverse force, so that the block 321 and the corresponding outlet holes 314 Disengagement, at this time, the refrigerant in the gas storage tank 2 is poured into the multiple flat tubes 13 through the multiple air outlet holes 314, and then flows into the compressor through the air outlet pipe 14 (at this time, the flow rate of the refrigerant flowing into the multiple flat tubes 13 in the unit increases, so the cold air temperature at the air outlet of the air conditioner drops rapidly). When the car encounters a blockage, in order to save electricity, the compressor can be stopped. At this time, the refrigerant no longer flows, and the refrigerant stored in the gas storage tank 2 flows out from the multiple through holes 3211 and flows into the multiple flat tubes 13 when the moving block 313 moves in the reverse direction (the multiple air outlet holes 314 are blocked by the blocking blocks 321 at the corresponding positions when the moving block 313 moves in the reverse direction). Although the cooling effect on the interior of the car is poor, it will not cause the temperature in the car to rise rapidly, and because the through holes The aperture of 3211 is relatively small, so the movement of the moving block 313 will be restricted by the refrigerant, making the reverse movement speed of the moving block 313 slow, so that when the compressor stops, the time for the air conditioner to discharge cold air can be extended. Since the multiple flat tubes 13 rotate in the fixed seat 1 through the two annular shells 11, when the blower is turned on, the wind blown out can be the rotation of the multiple flat tubes 13. Since the refrigerant temperature of the multiple flat tubes 13 is relatively low, a large amount of condensed water will be adsorbed on the outside of the flat tubes 13. The rotation of the multiple flat tubes 13 can throw out the condensed water adsorbed on the surface of the flat tubes 13, so as to accelerate the discharge of the condensed water on the surface of the flat tubes 13 and prevent the condensed water from being adsorbed on the flat tubes 13 for a long time, thereby reducing the breeding of bacteria.It is of great benefit to the health of the driver and passengers in the car. Since the blower draws in the outside air, it will cause the dust in the air to be adsorbed on the multiple flat tubes 13. At this time, the dust adsorbed on the multiple flat tubes 13 and mixed with the remaining condensed water can be cleaned by the cleaning mechanism 4 to prevent the dust from being adsorbed on the flat tubes 13, thereby avoiding the problem of poor cooling effect due to the obstruction of dust.

[0021] Embodiment 1:

[0022] like Figure 3-Figure 9 As shown, in this embodiment, a circular ring is fixedly connected to the opposite side of the two fixed nets 311 and located on the outside of the round rod 312, a clockwork spring is fixedly connected to the outer wall of the round rod 312, one end of the clockwork spring is fixedly connected to the inner wall of the circular ring at the corresponding position, a spiral groove is opened on the outer wall of the round rod 312, a sleeve that slides through the round rod 312 is fixed on one side of the moving block 313, a ball that slides in the spiral groove is fixedly connected to the inner wall of the sleeve, and two symmetrical limit rods 316 that slide through the moving block 313 are fixedly connected between the two fixed nets 311.

[0023] In this embodiment, by injecting refrigerant into the gas storage tank 2 from the air inlet pipe 21, the injected refrigerant can push the moving block 313 to move. Since the moving block 313 is restricted by the two limit rods 316, the moving block 313 can only translate but not rotate. Since the inner wall of the sleeve is fixed with a ball that slides with the spiral groove, the moving moving block 313 can rotate the round rod 312 through the ball, and the rotating round rod 312 can wind up the clockwork springs at both ends of the round rod 312. Until the moving block 313 moves to the other end of the gas storage tank 2, the multiple air outlet holes 314 are all opened, allowing the refrigerant to The inflow speed is accelerated. When the compressor stops, the refrigerant no longer flows into the gas tank 2, and the refrigerant in the gas tank 2 flows out from the multiple through holes 3211. Therefore, the pressure in the gas tank 2 becomes smaller and smaller, and the pressure acting on the moving block 313 also becomes smaller and smaller, so that the force acting on the two clockwork springs can also become smaller. Therefore, the round rod 312 rotates in the opposite direction under the release of the two clockwork springs. The reverse rotating round rod 312 can make the moving block 313 move in the opposite direction and compress the remaining refrigerant in the gas tank 2, so that the remaining refrigerant flows out from the multiple through holes 3211.

[0024] like Figure 6-Figure 8 As shown, in the present embodiment, circular grooves 315 are provided on one side of the movable block 313 and on both sides of the air outlet 314 at the corresponding position, a compression spring 323 fixedly connected to the inner bottom surface of the circular groove 315 at the corresponding position is fixedly connected to one side of the blocking block 321 at the corresponding circular groove 315, and a sealing gasket 3212 is fixedly connected to the side of the blocking block 321 opposite to the movable block 313.

[0025] In this embodiment, the blocking block 321 at the corresponding position can block the air outlet 314 at the corresponding position through the action of two compression springs 3213, so that the refrigerant poured into the gas storage tank 2 can push the moving block 313, and the sealing gasket 3212 can increase the sealing between the blocking block 321 and the air outlet 314 at the corresponding position.

[0026] like Figure 5-Figure 9 As shown, in the present embodiment, a magnetic ring 1 317 is embedded and fixed on one side of the fixed net 311 away from the air intake pipe 21, a connecting ring 323 is fixedly connected between one ends of a plurality of connecting rods 322, a magnetic ring 2 3231 attracted to the magnetic ring 1 317 is embedded and fixed on one side of the connecting ring 323, two symmetrical spherical grooves 3221 are provided on the outer wall of the connecting rod 322, a fixing frame 324 is fixedly connected to one side of the moving block 313 corresponding to the connecting rod 322, a cylindrical sleeve 3241 is penetrated and fixed on both opposite sides of the fixing frame 324, and a spring steel ball 3242 which is clamped with the spherical groove 3221 at the corresponding position is fixedly connected to the inside of the cylindrical sleeve 3241.

[0027] In this embodiment, when the moving block 313 moves toward the magnetic ring 1 317 under the action of the continuously penetrated refrigerant, the moving block 313 drives the multiple blocking blocks 321 and the connecting ring 323 to move. When the connecting ring 323 and the magnetic ring 1 317 are released, the continuously penetrated refrigerant will cause the pressure in the gas storage tank 2 to continue to increase. After the pressure in the gas storage tank 2 reaches a certain level, the connecting ring 323 is subjected to the reverse force of the magnetic ring 1 317, so that the connecting ring 323 moves toward the moving block 313. The movable connecting ring 323 can push open the multiple blocking blocks 321 through the multiple connecting rods 322, and the spring steel ball 3242 and the opposite The spherical groove 3221 at the corresponding position is engaged, so that the multiple air outlet holes 314 are in an open state. When the compressor stops working, the pressure in the gas tank 2 begins to gradually decrease, so that the round rod 312 drives the moving block 313 to move in the opposite direction. Since the magnetic ring 2 3231 at the connecting ring 323 is attracted to the magnetic ring 1 317, when the moving block 313 moves in the opposite direction, the connecting ring 323 drives the multiple blocking blocks 321 to move backward until the multiple blocking blocks 321 contact the moving block 313, and then move in the opposite direction together until they return to their original positions. At this time, the refrigerant in the gas tank 2 is completely discharged, and the car air conditioning outlet no longer discharges cold air.

[0028] Embodiment 2:

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the outer wall of the annular shell 11 is fixedly connected to a fixing ring 12 which is rotatably connected to the fixing seat 1 and is fixedly penetrated by the connecting pipe 22, and the ends of the air inlet pipe 21 and the air outlet pipe 14 are fixedly connected to a rotating joint 23, and the center of the rotating joint 23 is located on the same straight line as the center of the air storage tank 2 and the annular shell 11.

[0030] In this embodiment, the two annular shells 11 are respectively connected to the compressor and the expansion valve via two rotating joints 23 so that the two annular shells 11 drive the gas storage tank 2 to rotate.

[0031] Embodiment three:

[0032] like Fig.10 As shown, in this embodiment, the cleaning mechanism 4 includes two symmetrical reciprocating screws 41, an annular brush 42, and two symmetrical connecting blocks 43. The two symmetrical reciprocating screws 41 are rotatably connected between the two fixed rings 12, and the annular brush 42 is slidably connected between the two reciprocating screws 41. The two symmetrical connecting blocks 43 are fixedly connected to the outer walls of the annular brushes 42, and are penetrated and screwed with the reciprocating screws 41 at the corresponding positions. An inner side surface of the fixed seat 1 is fixedly connected to the ring gear 15, and one end of the outer wall of the reciprocating screw 41 is fixedly connected to a gear 44 meshing with the ring gear 15.

[0033] In this embodiment, the two reciprocating screws 41 and the annular brush 42 can be rotated along the axis of the annular shell 11 through the rotation of the annular shell 11. Since the ring gear 15 is engaged with the two gears 44, the reciprocating screw 41 rotating along the axis of the annular shell 11 rotates under the action of the gear 44 and the ring gear 15. The rotating reciprocating screw 41 can make the annular brush 42 reciprocate in the fixed seat 1, so that the dust adsorbed on the surface of the multiple flat tubes 13 can be cleaned, avoiding the problem of poor cooling effect due to the obstruction of dust.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
