Technical Field
[0001] This utility model relates to the field of cold storage air conditioning, specifically a pipe-type evaporator and a cold storage air conditioning system. Background Technology
[0002] An evaporator is a type of heat exchange device involving phase change and is a crucial component of the four main components of refrigeration systems. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. Cold storage air conditioning is an energy storage device and a key component of cold storage air conditioning systems. Air conditioning refrigeration equipment utilizes off-peak hours at night for cooling, storing cold energy in the form of chilled water or solidified phase change materials. During peak load periods, it partially or completely utilizes this stored cold energy to supply cooling to the air conditioning system.
[0003] Existing cold storage air conditioning pipe evaporators are prone to dust and impurities accumulating on their heat exchange pipes or external heat exchange fins during long-term use, which affects the heat exchange efficiency of the evaporator.
[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structural deficiencies and provide a pipe-type evaporator and a cold storage air conditioner. Utility Model Content
[0005] The purpose of this invention is to provide a pipe-type evaporator and a cold storage air conditioner to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe-type evaporator and a cold storage air conditioner, comprising a cylindrical outer shell, a heat exchange assembly, and a cleaning assembly. The heat exchange assembly is installed inside the cylindrical outer shell, and the heat exchange assembly includes a central circulation pipe and heat exchange fins. The central circulation pipe has a snake-shaped structure, and heat exchange fins are provided on the outer wall of the vertical pipe in the middle of the central circulation pipe. A flow guide hopper is installed below the cylindrical outer shell, and a filter screen is fixed on the upper side inside the flow guide hopper. An anti-clogging assembly is installed above the filter screen, and a cleaning assembly is installed above the anti-clogging assembly. The cleaning assembly includes a lead screw, a movable sleeve, a connecting rod, and an annular brush. A movable sleeve is sleeved on the outer side of the lead screw, and a connecting rod is fixed on the outer side of the movable sleeve. An annular brush is installed at the end of the connecting rod, and the annular brush is located on the outer side of the heat exchange fins.
[0007] Furthermore, the heat exchange assembly also includes a liquid inlet pipe and a steam exhaust pipe. The liquid inlet pipe is connected to the lower side of the central circulation pipe, and the steam exhaust pipe is connected to the upper side of the central circulation pipe. Both the liquid inlet pipe and the steam exhaust pipe penetrate the outer wall of the cylindrical outer shell.
[0008] Furthermore, an inlet pipe is connected to the lower part of the guide hopper, an upper cover frame is installed on the upper side of the cylindrical outer shell, and a vent pipe is connected to the upper part of the upper cover frame.
[0009] Furthermore, the anti-clogging component includes a motor, a rotating shaft, a fixing rod, and an anti-clogging brush. The upper side of the motor is provided with a rotating shaft, and the outside of the rotating shaft is connected to a fixing rod, and the lower side of the fixing rod is connected to an anti-clogging brush.
[0010] Furthermore, the lower side of the anti-clogging brush is in contact with the upper side of the filter screen, and two sets of anti-clogging brushes are symmetrically arranged about the center line of the rotating shaft.
[0011] Furthermore, the bottom of the lead screw is fixedly connected to the rotating shaft, and the vertical center lines of the rotating shaft and the lead screw coincide with the vertical center line of the cylindrical outer shell.
[0012] A cold storage air conditioner, which is equipped with a ducted evaporator as described above.
[0013] This utility model provides a pipe-type evaporator and a cold storage air conditioner, which has the following beneficial effects:
[0014] This utility model is equipped with an anti-clogging component and a cleaning component. The motor and rotating shaft facilitate the rotation of the fixed rod and the anti-clogging brush, so that the two sets of anti-clogging brushes can clean the surface of the filter screen to prevent clogging. At the same time, the rotation of the rotating shaft can drive the synchronous rotation of the lead screw, so that the outer moving sleeve of the lead screw can move up and down in the cylindrical outer shell, thereby driving the connecting rod and the annular sleeve brush to move up and down. This allows the annular sleeve brush to reciprocate and rub the outer surface of the heat exchange fins to remove dust, preventing dust from adhering to the outer wall of the heat exchange fins and affecting the heat exchange efficiency of the evaporator.
[0015] This invention is equipped with a heat exchange component. The liquid inlet pipe allows the refrigerant liquid to enter the interior of the snake-shaped central circulation pipe, enabling the refrigerant liquid inside the central circulation pipe to exchange heat with the gas inside the cylindrical outer shell. At this time, the heat exchange fins on the outside of the central circulation pipe can enhance the heat exchange efficiency, and the reciprocating lifting and lowering of several connecting rods can drive the airflow to tumble up and down, improving the convective heat transfer coefficient.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 3 As shown, a pipe-type evaporator and cold storage air conditioner includes a cylindrical outer shell 1, a heat exchange assembly 2, and a cleaning assembly 7. The heat exchange assembly 2 is installed inside the cylindrical outer shell 1. The heat exchange assembly 2 includes a central circulation pipe 201 and heat exchange fins 203. The central circulation pipe 201 has a serpentine structure, and heat exchange fins 203 are provided on the outer wall of the vertical pipe in the middle of the central circulation pipe 201. The heat exchange assembly 2 also includes a liquid inlet pipe 202 and a steam exhaust pipe 204. The liquid inlet pipe 202 is connected to the lower side of the central circulation pipe 201, and the steam exhaust pipe 204 is connected to the upper side of the central circulation pipe 201. Both the liquid inlet pipe 202 and the steam exhaust pipe 204 penetrate the outer wall of the cylindrical outer shell 1. A guide hopper 3 is installed at the bottom of the cylindrical outer shell 1, and a filter screen 5 is fixed on the upper side of the inside of the guide hopper 3. The bottom of the guide hopper 3 is connected to the inlet pipe 4, and the upper cover frame 8 is installed on the upper side of the cylindrical outer shell 1. The upper cover frame 8 is connected to the vent pipe 9. The liquid inlet pipe 202 allows the refrigerant liquid to enter the snake-shaped central circulation pipe 201. The exhaust pipe 204 facilitates the discharge of refrigerant vapor after heat absorption and evaporation, so that the refrigerant liquid inside the central circulation pipe 201 can exchange heat with the gas inside the cylindrical outer shell 1. At this time, the heat exchange fins 203 on the outside of the central circulation pipe 201 can enhance the heat exchange efficiency. The reciprocating lifting and lowering of several connecting rods 703 can drive the airflow to roll up and down, improving the convective heat transfer coefficient. The inlet pipe 4 and the guide hopper 3 facilitate the intake of gas into the cylindrical outer shell 1. Similarly, the vent pipe 9 at the upper cover frame 8 facilitates the discharge of gas after heat exchange and cooling.
[0022] like Figure 1 and Figure 2As shown, an anti-clogging component 6 is installed above the filter screen 5. The anti-clogging component 6 includes a motor 601, a rotating shaft 602, a fixing rod 603, and an anti-clogging brush 604. The rotating shaft 602 is located on the upper side of the motor 601, and the fixing rod 603 is connected to the outside of the rotating shaft 602. The anti-clogging brush 604 is connected to the lower side of the fixing rod 603. The lower side of the anti-clogging brush 604 is in contact with the upper side of the filter screen 5, and two sets of anti-clogging brushes 604 are symmetrically arranged about the center line of the rotating shaft 602. The filter screen 5 is used to filter and remove dust from the gas entering the cylindrical outer shell 1. The motor 601 and the rotating shaft 602 facilitate the rotation of the fixing rod 603 and the anti-clogging brush 604, so that the two sets of anti-clogging brushes 604 can clean the surface of the filter screen 5 to prevent dust or flocculent impurities from adhering and affecting the airflow at the position of the filter screen 5.
[0023] like Figure 1 and Figure 2 As shown, a cleaning component 7 is installed above the anti-clogging component 6. The cleaning component 7 includes a lead screw 701, a movable sleeve 702, a connecting rod 703, and an annular brush 704. The movable sleeve 702 is sleeved on the outside of the lead screw 701, and the connecting rod 703 is fixed to the outside of the movable sleeve 702. The annular brush 704 is installed at the end of the connecting rod 703 and is located on the outside of the heat exchange fins 203. The bottom of the lead screw 701 is fixedly connected to the rotating shaft 602, and the rotating shaft 602 and the lead screw 702 are connected to the rotating shaft 602. The vertical center line of rod 701 coincides with the vertical center line of cylindrical outer shell 1; the rotation of shaft 602 can drive the synchronous rotation of lead screw 701, so that the outer moving sleeve 702 of lead screw 701 can move up and down in cylindrical outer shell 1, thereby driving the connecting rod 703 and annular brush 704 to move up and down, so that the annular brush 704 can reciprocate to rub and clean the outer surface of heat exchange fins 203, preventing dust from adhering to the outer wall of heat exchange fins 203 and affecting the heat exchange efficiency of evaporator.
[0024] In summary, this ducted evaporator and cold storage air conditioner are first based on Figures 1 to 3 The structure shown allows the air requiring cooling in the cold storage air conditioner to be sent into the cylindrical outer shell 1 through the inlet pipe 4 and the guide hopper 3. At this time, the filter screen 5 can filter and remove dust from the gas entering the cylindrical outer shell 1. Then, the liquid inlet pipe 202 allows the refrigerant liquid to enter the interior of the snake-shaped central circulation pipe 201. Then, the refrigerant liquid inside the central circulation pipe 201 can exchange heat with the gas inside the cylindrical outer shell 1. At this time, the heat exchange fins 203 on the outside of the central circulation pipe 201 can enhance the heat exchange efficiency. Then, the exhaust pipe 204 facilitates the discharge of the refrigerant vapor after heat absorption and evaporation.
[0025] During this process, the motor 601 and the rotating shaft 602 drive the fixed rod 603 and the anti-clogging brush 604 to rotate, so that the two sets of anti-clogging brushes 604 can clean the surface of the filter screen 5 to prevent clogging. At the same time, the rotation of the rotating shaft 602 can drive the synchronous rotation of the lead screw 701, so that the outer moving sleeve 702 of the lead screw 701 can move up and down in the cylindrical outer shell 1, thereby driving the connecting rod 703 and the annular sleeve brush 704 to move up and down. This allows the annular sleeve brush 704 to reciprocate to rub and clean the outer surface of the heat exchange fins 203, preventing dust from adhering to the outer wall of the heat exchange fins 203 and affecting the heat exchange efficiency of the evaporator. Furthermore, the reciprocating up and down stirring of several connecting rods 703 can drive the airflow to tumble up and down, improving the convective heat transfer coefficient. Finally, after heat exchange and cooling, the gas is discharged through the vent pipe 9 at the upper cover frame 8.
