Description

Technical Field

[0001] This application relates to the field of evaporator technology, and more particularly to a temperature-controlled evaporator. Background Technology

[0002] An evaporator is a common heat exchange device widely used in refrigeration, chemical, and food processing industries. It is a very important component among the four major refrigeration equipment. Low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect.

[0003] However, existing temperature-controlled evaporators have the following drawbacks: for example, traditional evaporators usually adopt a fixed structure design, and their outlet air temperature is mainly achieved by adjusting the refrigerant flow rate or compressor power, but this temperature control method has the problems of slow response speed and high energy consumption. Summary of the Invention

[0004] The purpose of this application is to provide a temperature-controlled evaporator.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a temperature-controllable evaporator, comprising a shell, a baffle plate fixedly connected inside the shell, a through pipe fixedly connected inside the baffle plate, a driving device fixedly connected to the left side of the top of the shell, a driven device movably connected to the left side inside the shell, a connecting frame movably connected to the inside of the shell, the driving device comprising a motor fixedly connected to the left side of the top of the shell, a rotating shaft fixedly connected to the output end of the motor, and a driving gear fixedly connected to the outer side of the rotating shaft.

[0006] As a preferred embodiment, the outer casing includes a housing, a sealing ring is fixedly connected to the left side of the interior of the housing, a sealing shell is fixedly connected to the left side of the housing, an air inlet pipe is fixedly connected to the lower right side of the housing, a delivery pump is installed on the air inlet pipe, a fixing groove is provided on the inner side of the housing, and an air outlet pipe is fixedly connected to the upper right side of the housing.

[0007] As another preferred embodiment, the through pipe includes a heat exchange tube fixedly connected inside the baffle plate, with an input pipe fixedly connected to the upper end of the heat exchange tube and an output pipe fixedly connected to the lower end of the heat exchange tube.

[0008] More preferably, the driven device includes a rotating column fixedly connected to the left side inside the housing, and a driven gear fixedly connected to the outer side of the rotating column.

[0009] More preferably, the connecting frame includes a frame body movably connected inside the housing, and a toothed plate is fixedly connected to the left side of the frame body.

[0010] More preferably, the baffle includes a fixed cylinder fixedly connected inside the housing, a movable plate being movably connected inside the fixed cylinder, and a through hole being provided inside the fixed cylinder.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] This invention, by incorporating a driving device, a driven device, and a connecting frame, facilitates the adjustment of the distance between the moving plate and the inner wall of the housing. Starting the motor causes the rotating shaft to rotate clockwise, which in turn drives the driven gears on both sides to rotate counterclockwise. This counterclockwise rotation of the driven gears causes the rear gear plate to move to the left, which in turn moves the shorter frame to the left, moving the moving plate towards the left-side baffle plate. Simultaneously, it moves the front gear plate to the right, causing the longer frame to move the moving plate towards the right-side baffle plate. This reduces the distance between the moving plate and the inner wall of the housing. Reversing the rotation by controlling the motor increases this distance. The gap between the moving plate and the housing allows air to pass through. Changing the size of this gap alters the airflow speed, thus changing the heat exchange time between the air and the low-temperature condensate in the pipe. This allows for control of the discharged air temperature, resulting in fast temperature control response and low energy consumption. Attached Figure Description

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0023] like Figures 1-5The temperature-controlled evaporator shown includes a shell 1, a baffle plate 6 fixedly connected inside the shell 1, a through pipe 2 fixedly connected inside the baffle plate 6, a drive device 3 fixedly connected to the top left side of the shell 1, a driven device 4 movably connected to the left side inside the shell 1, and a connecting frame 5 movably connected to the inside of the shell 1. The drive device 3 includes a motor 301 fixedly connected to the top left side of the shell 1, a rotating shaft 302 fixedly connected to the output end of the motor 301, a drive gear 303 fixedly connected to the outer side of the rotating shaft 302, the drive gear 303 meshing with a driven gear 402, and the driven gear 402 meshing with a toothed plate 502. Starting the motor 301 causes the rotating shaft 302 to drive the drive gear 303 to rotate clockwise. The clockwise rotation of the drive gear 303 then drives the driven gears 402 on both sides to rotate counterclockwise. The counterclockwise rotation of the driven gears 402 then drives the toothed plate 502 on the rear side. 02 moves to the left, which in turn drives the shorter frame 501 to move the moving plate 602 towards the left side of the baffle 6. At the same time, it drives the front toothed plate 502 to move to the right, which in turn drives the longer frame 501 to move the moving plate 602 towards the right side of the baffle 6. This makes the distance between the moving plate 602 and the inner wall of the housing 101 smaller. By controlling the motor 301 to drive the rotating shaft 302 to reverse, the distance between the moving plate 602 and the inner wall of the housing 101 can be increased. The gap between the moving plate 602 and the housing 101 is used for air passage. By changing the size of the gap between the moving plate 602 and the housing 101, the speed of air passage can be changed, which in turn changes the heat exchange time between the air and the low-temperature condensate in the pipe 2. This allows the temperature of the discharged air to be controlled. The temperature control has a fast response speed and low energy consumption.

[0024] Furthermore, the outer casing 1 includes a housing 101, and the frame 501 can move inside the housing 101. A sealing ring 102 is fixedly connected to the left side inside the housing 101. The sealing ring 102 is used to ensure better sealing between the frame 501 and the housing 101. A sealing shell 103 is fixedly connected to the left side of the housing 101. An air inlet pipe 105 is fixedly connected to the lower right side of the housing 101. A delivery pump 104 is installed on the air inlet pipe 105. A fixing groove 106 is provided on the inner side of the housing 101. An air outlet pipe 107 is fixedly connected to the upper right side of the housing 101. Activating the delivery pump 104 allows air to enter the housing 101 through the air inlet pipe 105 and be discharged through the air outlet pipe 107.

[0025] Furthermore, the through pipe 2 includes a heat exchange pipe 202 fixedly connected inside the baffle plate 6. The heat exchange pipe 202 is located inside the shell 101 and is used to exchange heat with the air entering the shell 101. An inlet pipe 201 is fixedly connected to the upper end of the heat exchange pipe 202. The inlet pipe 201 is used for the entry of low-temperature condensate. An outlet pipe 203 is fixedly connected to the lower end of the heat exchange pipe 202. The outlet pipe 203 is used for the discharge of the vaporized condensate after the heat exchange is completed.

[0026] Furthermore, the driven device 4 includes a rotating column 401 fixedly connected to the left side inside the housing 1, and a driven gear 402 fixedly connected to the outside of the rotating column 401. The rotating column 401 can rotate inside the sealed housing 103, thereby enabling the driven gear 402 to rotate.

[0027] Furthermore, the connecting frame 5 includes a frame body 501 movably connected inside the outer casing 1. A toothed plate 502 is fixedly connected between the frame bodies 501 on the left side. The frame body 501 on the rear connecting frame 5 is shorter in length and is fixedly connected to the movable plate 602 in the left baffle 6. The frame body 501 on the front connecting frame 5 is longer in length and is fixedly connected to the movable plate 602 in the right baffle 6.

[0028] Furthermore, the baffle 6 includes a fixed cylinder 601 fixedly connected inside the outer shell 1. A movable plate 602 is movably connected inside the fixed cylinder 601. The movable plate 602 can move inside the fixed cylinder 601. The fixed cylinder 601 has a through hole 603 for the heat exchange tube 202 to pass through. The fixed directions of adjacent baffles 6 are opposite. The right side of the uppermost baffle 6 is fixedly connected to the outer shell 101, while the movable plate 602 faces to the left and is a certain distance from the inner wall of the outer shell 101. The adjacent lower baffles 6 are arranged oppositely, so that the interior of the outer shell 101 is formed by the baffles 6 into a tortuous flow path, ensuring that the air can fully contact the heat exchange tube 202 and that the air and the low-temperature condensate can exchange heat fully.

[0029] Working principle: During use, low-temperature condensed liquid is input into heat exchange tube 202 through input pipe 201 and discharged through output pipe 203. The delivery pump 104 is activated, allowing air to enter the housing 101 through intake pipe 105 to exchange heat with heat exchange tube 202 and be discharged through outlet pipe 107. The motor 301 is activated, causing the rotating shaft 302 to drive the drive gear 303 to rotate clockwise. This clockwise rotation of the drive gear 303 drives the driven gears 402 on both sides to rotate counterclockwise. The counterclockwise rotation of the driven gears 402 causes the rear gear plate 502 to move to the left, which in turn causes the shorter frame 501 to move the moving plate 602 towards the left side of the baffle plate 6, simultaneously driving the front... The toothed plate 502 moves to the right, which in turn drives the longer frame 501 to move the moving plate 602 towards the right side of the baffle plate 6. This reduces the distance between the moving plate 602 and the inner wall of the housing 101. By controlling the motor 301 to drive the rotating shaft 302 to reverse, the distance between the moving plate 602 and the inner wall of the housing 101 can be increased. The gap between the moving plate 602 and the housing 101 is used for air passage. By changing the size of the gap between the moving plate 602 and the housing 101, the air passage speed can be changed, which in turn changes the heat exchange time between the air and the low-temperature condensate in the pipe 2. This allows for control of the temperature of the discharged air. The temperature control has a fast response speed and low energy consumption.
