[0002] Currently, in air conditioning technologies, air-cooled computer room air conditioners are generally installed in computer rooms, data centers, and electronic equipment rooms to maintain stable ambient temperatures. Therefore, air-cooled computer room air conditioners not only have cooling but also heating functions. However, because the heaters used for heating in air-cooled computer room air conditioners are typically installed inside the evaporator, and these heaters are relatively large, they obstruct the output of cold air during cooling mode.

Therefore, they should not be construed as limitations on this utility model.

[0063] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium.

[0064] In the related technologies of air-cooled computer room air conditioning, in order to maintain a stable ambient temperature, the air conditioning system not only has cooling functions but also heating functions. However, because the heater used in the heating function of air-cooled downdraft computer room air conditioning is generally installed inside the evaporator, and the heater is generally quite large, and when the air-cooled computer room air conditioning is running in cooling mode, the heater will obstruct the cold air output by the air-cooled computer room air conditioning, reducing the cold air flow and causing a decrease in the cooling efficiency of the air-cooled computer room air conditioning, thus affecting the stability of the ambient temperature in computer rooms, data centers, electronic equipment rooms, and other similar locations.

[0065] Based on this technical problem, the following embodiments are proposed.

[0066] Example 1

[0067] like Figure 1 and Figure 2 As shown, this embodiment proposes a heating device, particularly suitable for use as a heating device in air-cooled computer room air conditioning, which includes:

[0068] Heating assembly 130, which includes heating element 136;

[0069] First support assembly 110, the first support assembly 110 includes a rod 114;

[0070] The second support assembly 120 includes a movable part 122 and a first connecting part 124. The movable part 122 is sleeved together with the rod body 114 in a relatively vertical manner.

[0071] One end of the heating element 136 is hinged to the top of the rod 114, and the other end is hinged to one end of the first connecting member 124. The other end of the first connecting member 124 is hinged to the moving member 122.

[0072] The heating element 136 is configured to adjust the opening angle of the heating element 136 relative to the rod 114 by the relative lifting and lowering movement of the moving element 122 and the rod 114.

[0073] It should be noted that the opening angle of the heating element 136 relative to the rod 114 is also the rotation angle of the heating element 136 about the hinge point relative to the rod 114. When the opening angle is equal to 0, the heating element 136 is in a closed state relative to the rod 114; when the opening angle is greater than 0, the heating element 136 is in an open state relative to the rod 114. When the heating device 100 is not required to work, the heating element 136 is controlled to be in a closed state relative to the rod 114. When the heating device 100 is required to work, the heating element 136 is controlled to be in an open state relative to the rod 114. The opening angle of the heating element 136 relative to the rod 114 can be adjusted according to the heat exchange requirements of the heating device 100. The opening angle is usually set between a minimum angle and a maximum angle, preferably 0 degrees to 90 degrees.

[0074] Furthermore, the heating device 100 in this embodiment is preferably an electric heating device, but this application is not limited to electric heating devices. For example, infrared heaters, electromagnetic heaters, and methods such as internally setting heat exchange medium or other methods to achieve heat exchange are all possible.

[0075] Furthermore, as an optional embodiment, the heating element 136 of the heating device 100 can be configured to be openable and closable in the form of a strip, rod, plate, umbrella, filament, or mesh. Regardless of the form, it is important that the heating effect on the airflow can be controlled by the state transition of the relative rod 114 being open or closed.

[0076] Therefore, this invention improves the cooling effect of the unit by reducing the overall volume of the heating device 100 when the computer room air conditioner is operating in cooling mode. The opening and closing of the heating element 136 is achieved through the first support assembly 110 and the second support assembly 120, thereby controlling the overall size of the heating device 100. When the computer room air conditioner is heating, the heating element 136 is opened by program control, expanding the heat dissipation area and improving the unit's heating effect; when the computer room air conditioner is cooling, the heating device 100 is closed to reduce its wind-blocking area and improve the unit's cooling effect. This structure operates smoothly, is simple, and is feasible.

[0077] When the heating element 136 is in the closed state of cooling operation, the angle between the heating element 136 and the rod 114 is the set minimum angle, and the moving part 122 is at the set bottom end of the rod 114. When the electric heating is in the open state of heating operation, the angle between the heating element 136 and the rod 114 is the set maximum angle, and the moving part 122 is at the set top end.

[0078] Furthermore, in combination Figure 1 and Figure 2As shown, the heating device 100 includes a first support assembly 110, a second support assembly 120, and a heating element 130. When the first support assembly 110 moves, it can drive the second support assembly 120 to move. Assuming the first end of the heating element 136 is A and the second end is B, connecting the first end of the heating element 136 to the first support assembly 110 allows the first end of the heating element 136 to maintain a constant relative position with the first support assembly 110 during the movement of the heating element 130, thereby limiting the range of motion of the heating element 136. Connecting the second end of the heating element 136 to the second support assembly 120 allows the second support assembly 120 to drive the second end of the heating element 136 to move when the first support assembly 110 drives the second support assembly 120 to move.

[0079] Combination Figure 1 As shown, in heating mode, the first support assembly 110 drives the second support assembly 120 to rise axially along the rod 114. During the movement, the second support assembly 120 drives the second end of the heating element 136 to move away from the first support assembly 110, assuming this direction is direction P. At this time, the heating element 136 gradually opens, and the volume of the heating device 100 increases. When the air-cooled computer room air conditioner 300 is operating in heating mode, since the surface temperature of the evaporator 210 inside the air-cooled computer room air conditioner 300 is close to the temperature of the external environment, the increased volume of the heating device 100 can increase the heat exchange area between the heating element 130 and the air. At this time, the fan 220 mixes the heat generated by the heating element 130 with the air and blows it out of the air-cooled computer room air conditioner 300, which can further improve the heating efficiency.

[0080] Combination Figure 2 As shown, in cooling mode, the first support assembly 110 drives the second support assembly 120 to descend axially along the rod 114. During this movement, the second support assembly 120 drives the second end of the heating assembly 130 to move closer to the first support assembly 110 (let's say direction Q). At this time, the heating assembly 130 gradually closes, and the volume of the heating device 100 decreases. When the air-cooled computer room air conditioner 300 operates in cooling mode, the temperature of the evaporator 210 drops rapidly, and the airflow through the evaporator 210 forms cold air. Since the heating device 100 is located inside the evaporator 210, reducing its volume decreases the exhaust space occupied by the heating device 100, avoiding obstruction of the cold air blown out by the fan 220, thereby improving cooling efficiency and maintaining a stable ambient temperature in computer rooms, data centers, electronic equipment rooms, and other similar locations. The first support assembly 110 and the second support assembly 120 of this heating device 100 have simple structures, operate smoothly, and are highly feasible.

[0081] Preferably, the first connector 124 can be slidably connected to the movable member 122 or threadedly connected to the movable member 122.

[0082] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2 As shown,

[0083] Multiple heating elements 136 are provided, and multiple first connecting elements 124 are provided. Each heating element 136 corresponds to a first connecting element 124. One end of each heating element 136 is hinged to the top of the rod 114, and the other end of each heating element 136 is hinged to one end of the corresponding first connecting element 124. The other ends of each first connecting element 124 are hinged to the moving element 122.

[0084] Multiple heating elements 136 are distributed in an umbrella shape along the circumference of the rod 114.

[0085] In this embodiment, as Figure 1 and Figure 2 As shown, the number of heating elements 136 is set to be multiple, and the number of first connecting elements 124 is also multiple. The heating elements 136 and the first connecting elements 124 are arranged in a one-to-one correspondence. One end of each of the multiple heating elements 136 is hinged to the top of the rod 114, and the other end of the heating element 136 is hinged to one end of the corresponding first connecting element 124. The other ends of each of the multiple first connecting elements 124 are hinged to the moving element 122. The hinge structure enables the heating elements, the first connecting elements and the moving element to maintain a stable connection relationship during relative movement. Multiple heating elements 136 are arranged in an umbrella shape along the circumference of the rod 114. When the moving member 122 moves and drives the first connecting member 124 to rotate relative to the heating elements 136, the first connecting member 124 can drive the heating elements 136 to rotate relative to the rod 114. Thus, in the heating mode, the opening angle of the heating elements 136 relative to the rod 114 can be increased, and the heating device 100 opens in an umbrella shape. In the cooling mode, the opening angle of the heating elements 136 relative to the rod 114 can be decreased, and the heating device 100 closes in a bundle shape. This changes the volume of the heating device 100 to adapt to the needs of different modes.

[0086] Preferably, the heating element 136 is an electric heating element, which is in the form of a strip, rod, or wire, to adapt to different requirements for the shape of the heating element 136 in different spaces.

[0087] Specifically, the number of heating elements 136 is greater than or equal to two, and the number of first connecting elements 124 is greater than or equal to two.

[0088] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2As shown, the moving part 122 is a slider structure, and the rod 114 is a lead screw structure.

[0089] In this embodiment, as Figure 1 and Figure 2 As shown, the moving part 122 is a slider structure and the rod 114 is a lead screw structure. Since the slider structure is sleeved on the lead screw structure, the movement of the lead screw structure can drive the slider structure to move on the lead screw structure, thereby driving the first connecting part 124 to move, and thus controlling the opening angle of the heating part 136 relative to the rod 114 to change the volume of the heating device 100.

[0090] Preferably, the slider structure can be a nut seat, and the screw structure can be a ball screw. The opening and closing of the heating element is achieved through the ball screw structure and the hinge structure of the electric heating element, thereby controlling the overall size of the heating device 100. For example, when the computer room air conditioner is cooling, the volume of the electric heating part is reduced, decreasing the airflow; when the computer room air conditioner is heating, the volume of the electric heating part is increased, increasing the heat dissipation area and improving the heating effect.

[0091] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2 As shown, the heating device also includes a power unit 150, which is used to drive the moving member 122 or the rod 114 to rotate.

[0092] In this embodiment, as Figure 1 and Figure 2 As shown, the heating device also includes a power unit 150, which provides power to the heating device 100. The power unit 150 can drive the moving member 122 or the rod 114 to rotate, thereby changing the opening angle of the heating member 136 relative to the rod 114 when the moving member 122 and the rod 114 move relative to each other, thereby controlling the heating device 100 to open in an umbrella shape or close in a bundle shape.

[0093] Preferably, the power unit 150 includes a motor, the output end of which is connected to the input end of the moving member 122 or the rod 114 to drive the moving member 122 or the rod 114 to move.

[0094] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2 As shown, the first support assembly 110 also includes a support frame 140, and the rod 114 is rotatably mounted on the support frame 140. The power unit 150 is drivenly connected to the rod 114.

[0095] In this embodiment, as Figure 1 and Figure 2As shown, the first bracket assembly 110 also includes a support frame 140, which provides installation space for related components and supports the entire heating device 100 by connecting to the rod 114.

[0096] Preferably, the rod 114 is rotatably connected to the support frame 140, so that the rod 114 maintains a constant relative position with the support frame 140 when rotating relative to it. By rotating the rod 114 in both forward and reverse directions relative to the support frame 140, the moving member 122 can be driven to move in either a first or second direction. A power unit 150 can be mounted on the support frame 140, with its output end connected to the input end of the rod 114. When the heating device 100 starts operating, the power unit 150 drives the rod 114 to rotate relative to the support frame 140, and the rod 114 drives the moving member 122 to move in either the first or second direction, thereby changing the opening angle of the heating member 136 relative to the rod 114, and thus controlling the overall volume change of the heating device 100.

[0097] Preferably, the rod 114 can be pinned to the support frame 140, connecting the output end of the motor to the input end of the rod 114, thereby adjusting the volume of the heating device 100 to adapt to the needs of different modes.

[0098] Preferably, the rod body is a lead screw, and the moving part is a slider that cooperates with the lead screw.

[0099] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2 As shown, a first angle is formed between the heating element 136 and the rod 114, and a second angle is formed between the heating element 136 and the first connecting member 124;

[0100] The power unit 150 drives the rod 114 to rotate in the first direction, and the moving part 122 rises along the axial direction of the rod 114, increasing the first included angle and decreasing the second included angle;

[0101] The power unit 150 drives the rod 114 to rotate in the second direction, and the moving part 122 descends along the axial direction of the rod 114, the first included angle decreases, and the second included angle increases;

[0102] The first direction and the second direction are opposite.

[0103] In this embodiment, as Figure 1 and Figure 2As shown, since the first end of the heating element 136 is connected to the rod 114, and the second end of the heating element 136 can move relative to the rod 114 through a hinge with the first connecting member 124, a first angle can be formed between the heating element 136 and the rod 114, and a second angle can be formed between the heating element 136 and the first connecting member 124. Assuming the first direction is direction J, when the power unit 150 drives the rod 114 to rotate in the first direction, causing the moving member 122 to rise axially along the rod 114, the first connecting member 124 can drive the second end of the heating element 136 to move away from the rod 114. At this time, the first angle gradually increases, and the second angle gradually decreases. The greater the distance between the second end of the heating element 136 and the rod 114, the larger the first angle and the smaller the second angle. Assuming the second direction is direction K, when the power unit 150 drives the rod 114 to rotate in the second direction, causing the moving member 122 to descend axially along the rod 114, the first connecting member 124 can drive the second end of the heating member 136 to move closer to the rod 114. At this time, the first included angle gradually decreases, and the second included angle gradually increases. The smaller the distance between the second end of the heating member 136 and the rod 114, the smaller the first included angle and the larger the second included angle. In this implementation, the heating device 100 can control the opening and closing posture of the heating member 136 by adjusting the displacement of the moving member 122, or by adjusting the size of the first and second included angles, so that the volume of the heating device 100 can be varied according to the user's needs in different control modes.

[0104] Specifically, if Figure 1 and Figure 2 As shown, in cooling mode, the heating element 136 is in a closed state, with the first included angle at its minimum and the second included angle at its maximum, and the moving element 122 reaches its maximum stroke moving downward along the axis of the rod 114. In heating mode, the heating element 136 is in an open state, with the first included angle at its maximum and the second included angle at its minimum, and the moving element 122 reaches its maximum stroke moving upward along the axis of the rod 114.

[0105] Optionally, in one implementation of this embodiment, such as Figure 1 and Figure 2 As shown, a second connector 112 is provided at the top of the rod 114, and one end of each of the multiple heating elements 136 is hinged to the second connector 112.

[0106] In this embodiment, as Figure 1 and Figure 2As shown, a second connecting member 112 is also provided at the top of the rod 114, and the second connecting member 112 can rotate relative to the rod 114. The input end of the rod 114 is connected to the output end of the motor, and the motor provides power to the rod 114. One end of each of the multiple heating elements 136 is hinged to the second connecting member 112. The rod 114 is configured to rotate relative to the second connecting member 112 and the second support assembly 120. When the motor drives the rod 114 to rotate in the first or second direction, the moving member 122 is driven by the rod 114 to move, thereby realizing the upward or downward movement along the axial direction of the rod 114. Connecting one end of the heating element 136 to the second connecting member 112 can limit the range of motion of the heating element 136, and the relative position between the second connecting member 112 and the heating element 136 can remain unchanged during the rotation of the rod 114, so that the heating element 136 and the rod 114 can still maintain a stable connection when the rod 114 is moving. The first included angle is formed by the heating element 136 and the second connecting element 112. When the moving element 122 rises along the axial direction of the rod 114, the heating element 136 rotates away from the rod 114, and the first included angle increases. When the moving element 122 descends along the axial direction of the rod 114, the heating element 136 rotates towards the rod 114, and the first included angle decreases.

[0107] Preferably, such as Figure 1 and Figure 2 As shown, the first connector 124 and the moving part 122 can be connected by a pin or by a hinge. The three sets of rotating connection structures formed by the heating part 136, the rod 114 and the first connector 124 respectively form a stable triangular structure, which further improves the structural stability of the heating device 100 during the volume change process. This makes the heating component 130 smoother when adjusting the opening and closing postures, and further reduces the risk of jamming of the heating device 100 during the volume change process.

[0108] Preferably, the motor can drive the rod 114 to move through a coupling or through a synchronous pulley.

[0109] Preferably, the first included angle is greater than 0 degrees and less than 90 degrees, and the second included angle is greater than 45 degrees and less than 180 degrees.

[0110] Specifically, if Figure 1 As shown, the top of rod 114 is G.

[0111] Optionally, in one implementation of this embodiment, such as Figure 1-3 As shown, the second support assembly 120 also includes:

[0112] Controller 125 and distance sensor 126;

[0113] A distance sensor 126 is disposed on the moving part 122 and is used to detect the distance information of the moving part 122 relative to the support frame 140;

[0114] The controller 125 controls the drive of the power unit 150 to the moving part 122 based on the distance information, thereby controlling the movement and stopping of the moving part 122.

[0115] In this embodiment, as Figure 1-3 As shown, the second support assembly 120 also includes a controller 125 and a distance sensor 126. The distance sensor 126 is disposed on the moving part 122 and can continuously detect the distance information of the moving part 122 relative to the support frame 140. The distance sensor 126 is electrically connected to the controller 125 so that the distance information of the moving part 122 relative to the support frame 140 is fed back to the controller 125 to control the drive of the power unit 150 on the moving part 122, thereby controlling the movement and stopping of the moving part 122, so that the heating device 100 can reduce its volume in the cooling mode and increase its volume in the heating mode.

[0116] Preferably, the distance between the distance sensor 126 and the support frame 140 is set to L, and the distance between the moving part 122 and the support frame 140 is set to M. Setting L equal to M ensures that the first support assembly 110 does not protrude beyond the distance sensor 126 in the direction towards the support frame 140. This prevents some signals emitted by the distance sensor 126 from being blocked by the first support assembly 110, allowing the distance sensor 126 to receive the reflected signals to the maximum extent possible. This enables accurate measurement of the distance between the first support assembly 110 and the support frame 140, further improving the displacement accuracy of the moving part 122 on the rod 114. Consequently, the heating device 100 can more accurately adjust the opening and closing postures of the heating assembly 130 to adapt to different user requirements for the size of the heating device 100 under different control modes.

[0117] Specifically, when the air-cooled computer room air conditioner 300 is in a low temperature environment and the heating mode is turned on, the power unit 150 starts and controls the rod 114 to move along the first direction, thereby driving the moving part 122 to rise along the axial direction of the rod 114. At the same time, the heating device 100 also gradually opens, the first included angle gradually increases, and the second included angle gradually decreases. With the heating assembly 130 fully open, the distance between the moving part 122 and the support frame 140 is set to a first preset distance. When the distance sensor 126 detects that the L value equals the first preset value, the power unit 150 stops driving, and the moving part 122 also stops moving. The first included angle reaches its maximum value, the second included angle reaches its minimum value, and the volume of the heating device 100 reaches its maximum value. At this time, the heat dissipation effect of the heating device 100 is optimal, and it can heat up the external environment of the air-cooled computer room air conditioner 300 to the greatest extent. When the air-cooled computer room air conditioner 300 is in a high-temperature environment and the cooling mode is turned on, the power unit 150 starts and controls the rod 114 to move in the second direction, thereby driving the moving part 122 to descend axially along the rod 114. At the same time, the heating device 100 gradually closes, the first included angle gradually decreases, and the second included angle gradually increases. With the heating assembly 130 fully closed, the distance between the moving part 122 and the support frame 140 is set to a second preset distance, which is less than the first preset value. When the distance sensor 126 detects that the L value is equal to the second preset value, the power unit 150 stops driving, and the moving part 122 also stops moving. The first included angle reaches the minimum value, the second included angle reaches the maximum value, and the volume of the heating device 100 reaches the minimum value. At this time, the heating device 100 has the least impact on the cold air flow, so that the air-cooled computer room air conditioner 300 can cool and reduce the external environment to the maximum extent.

[0118] Optionally, in one implementation of this embodiment, the heating element 136 is an electric heating element, such as an electric heating rod, an electric heating wire, an electric heating strip, or a foldable electric heating mesh.

[0119] In this embodiment, the heating element 136 can be an electric heating element, which can be in the shape of an electric heating rod, an electric heating wire, an electric heating strip, or a foldable electric heating mesh, etc. The above-mentioned electric heating elements of different shapes can make the heating device 100 more precisely adjust to changes in volume, thereby meeting the usage requirements of the heating device 100 in different installation spaces.

[0120] Example 2

[0121] This embodiment provides a heat exchange system 200, such as Figure 3 and Figure 4 As shown, it includes an evaporator 210, a fan 220 and a heating device 100 as in Embodiment 1. The fan 220 is disposed between the evaporator 210 and the air outlet 332, and the evaporator 210 surrounds the heating device 100.

[0122] In this embodiment, as Figure 3 and Figure 4 As shown, after the evaporator 210 is enclosed, an installation space is formed in the middle. The heating device 100 is installed in this installation space, and the fan 220 is placed between the evaporator 210 and the air outlet 332, which can blow the air that has completed heat exchange near the evaporator 210 out of the air outlet. In cooling mode, the evaporator 210 cools the surrounding air to generate cold air, and the fan 220 blows the cold air towards the air outlet 332. In heating mode, the evaporator 210 stops working, the heating device 100 heats the surrounding air to generate hot air, and the fan 220 blows the hot air towards the air outlet 332. Since the heat exchange system 200 includes the heating device 100 in the above embodiment, the heat exchange system 200 has all the beneficial effects of the heating device 100 in the above embodiment, which will not be described again here.

[0123] Preferably, the heat exchange system 200 can also operate in reheat dehumidification mode. In reheat dehumidification mode, the evaporator 210 and the heating device 100 operate simultaneously. The heating device 100 can heat the humid air after it has been dehumidified by the evaporator 210, so that the air flowing out of the air outlet 332 can achieve both dehumidification and reach a suitable temperature.

[0124] Optionally, in one implementation of this embodiment, such as Figure 3 and Figure 4 As shown, in heating mode, the heating device 100 opens to heat the air, and the evaporator 210 stops operating. In cooling mode, the heating device 100 closes to stop heating the air, and the evaporator 210 operates.

[0125] In this embodiment, as Figure 3 and Figure 4 As shown, in heating mode, the heating elements 136 of the heating device 100 are all open and begin to heat up to heat the surrounding air. At this time, the evaporator 210 stops operating, and the hot airflow after heat exchange with the heating device 100 is blown out of the air outlet 332 by the fan 220. In cooling mode, the heating elements 136 of the heating device 100 are all closed and stop working. At this time, the evaporator 210 starts operating to cool the surrounding air, and the cold airflow after heat exchange with the evaporator 210 is blown out of the air outlet 332 by the fan 220.

[0126] Since the heat exchange system 200 includes a heating device 100, when the ambient temperature in the computer room is low, the heat exchange system 200 can operate in heating mode. At this time, the evaporator 210 stops working, and the heat exchange system 200 controls the heating device 100 to increase in size. At this time, the heat exchange device 100 has the largest heat exchange area with the surrounding air, and the generated hot airflow is the most efficient. The heat exchange system 200 heats the computer room by blowing the hot airflow generated by the heating device 100 out of the air outlet 332, so that the temperature can rise rapidly to the operating temperature. When the ambient temperature in the computer room is high, the heat exchange system 200 can operate in cooling mode. At this time, the heating device 100 stops working, and the heat exchange system 200 controls the heating device 100 to decrease in size to reduce the wind resistance it generates on the blown airflow. The fan 220 blows the cold airflow generated by the evaporator 210 towards the air outlet 332. Since the wind resistance in the air duct is small, the flow rate of the blown cold airflow is large, thereby achieving rapid cooling of the computer room and rapidly lowering the temperature to the operating temperature. The heat exchange system 200 further improves the temperature regulation efficiency in the computer room by controlling the change in the volume of the heating device 100, thereby enabling the computer room to maintain normal operation.

[0127] Example 3

[0128] This embodiment provides an air-cooled computer room air conditioner 300, such as... Figure 3 and Figure 4 As shown, it includes a housing 310 and a heat exchange system 200 as in Embodiment 2.

[0129] In this embodiment, as Figure 3 and Figure 4 As shown, the air-cooled computer room air conditioner 300 includes a housing 310 and a heat exchange system 200 as described in Embodiment 2. Therefore, the air-cooled computer room air conditioner 300 possesses all the beneficial effects of the heat exchange system 200 as described in Embodiment 2, which will not be elaborated further here.

[0130] Preferably, the air-cooled computer room air conditioner 300 can be an air-cooled computer room air conditioner 300.

[0131] Optionally, in one implementation of this embodiment, such as Figure 3 and Figure 4 As shown, the housing 310 includes:

[0132] The heat exchange chamber 320, the heating device 100 and the evaporator 210 are all disposed in the heat exchange chamber 320, and the heat exchange chamber 320 is provided with an air inlet 322;

[0133] Air outlet 330 is connected to heat exchange chamber 320. Fan 220 is installed in air outlet 330. Air outlet 332 is installed on the side of air outlet 330 away from heat exchange chamber 320.

[0134] In this embodiment, as Figure 3 and Figure 4 As shown, the housing 310 includes a heat exchange chamber 320 and an air outlet chamber 330. The heating device 100 and the evaporator 210 are both disposed in the heat exchange chamber 320. The heat exchange chamber 320 has an air inlet 322, and the airflow enters the heat exchange chamber 320 from the air inlet 322. The air outlet chamber 330 is connected to the heat exchange chamber 320. The fan 220 is disposed in the air outlet chamber 330, and the air outlet 332 is disposed on the side of the air outlet chamber 330 away from the heat exchange chamber 320. The airflow after being processed by the heat exchange chamber 320 enters the air outlet chamber 330 from the connection between the air outlet chamber 330 and the heat exchange chamber 320. Under the action of the fan 220, it is blown out from the side of the air outlet chamber 330 away from the heat exchange chamber 320.

[0135] Specifically, if Figure 4 As shown, the side of the air outlet cavity 330 away from the heat exchange cavity 320 is W.

[0136] Example 4

[0137] This embodiment provides a control method, such as Figure 5 As shown, the control method for controlling the heat exchange system as described in Embodiment 2 above or the air-cooled computer room air conditioner as described in Embodiment 3 above includes:

[0138] Receive control commands;

[0139] The control command is identified as being in heating mode;

[0140] Obtain the distance value between the distance sensor and the support frame;

[0141] Determine whether the distance between the distance sensor and the support frame is equal to the preset first distance value;

[0142] If not, the motor starts and drives the moving part to rise along the rod axis;

[0143] If so, the motor will stop.

[0144] In this embodiment, as Figure 5As shown, this control method can be used to control both the heat exchange system in Embodiment 2 and the air-cooled computer room air conditioner in Embodiment 3. This method controls the displacement of the moving component on the first support assembly by monitoring the distance between the distance sensor and the support frame, thereby enabling the heating component to achieve open and closed states. The control method first identifies the received control command. When the control command is for heating mode, the distance sensor acquires its distance from the support frame and determines whether this distance equals a preset first distance value. If the distance is not equal to the preset first distance value, it indicates that the heating component is not yet fully open. At this time, the motor starts, driving the moving component to rise axially along the rod, and the heating component continues to open. When the distance sensor determines that the distance equals the preset first distance value, it controls the motor to disconnect, the moving component stops moving, and the heating component is now fully open, reaching its maximum volume. By monitoring the distance between the distance sensor and the support frame to control the displacement of the moving component on the first support assembly, the opening and closing postures of the heating component can be adjusted more accurately to meet the user's different needs for the heating device volume under different control modes.

[0145] like Figure 5 As shown, specifically, the control method includes:

[0146] Step 202: Receive control commands;

[0147] Step 204: Identify the control command as heating mode;

[0148] Step 206: Obtain the distance value between the distance sensor and the support frame;

[0149] Step 208: Determine whether the distance between the distance sensor and the support frame is equal to the preset first distance value;

[0150] Step 210: If not, the motor starts and drives the moving part to rise along the rod axis;

[0151] Step 212: If yes, the motor stops.

[0152] Optionally, in one implementation of this embodiment, such as Figure 6 As shown,

[0153] Receive control commands;

[0154] The control command was identified as being in cooling mode.

[0155] Obtain the distance value between the distance sensor and the support frame;

[0156] Determine whether the distance between the distance sensor and the support frame is equal to the preset second distance value;

[0157] If not, the motor starts and drives the moving part to descend along the rod axis;

[0158] If so, the motor will stop.

[0159] In this embodiment, as Figure 6 As shown, when the control command is in cooling mode, the distance sensor acquires the distance value between itself and the support frame and determines whether this distance value equals a preset second distance value. If the distance value does not equal the preset second distance value, it indicates that the heating component is not yet fully closed. At this time, the motor starts, driving the moving part to descend along the rod axis, and the heating component continues to close. When the distance sensor determines that the distance value equals the preset second distance value, it controls the motor to disconnect, and the moving part stops moving. At this time, the heating component is fully closed, and the volume of the heating device reaches the specified value. By monitoring the distance value between the distance sensor and the support frame to control the displacement of the moving part on the first support assembly, the opening and closing postures of the heating component can be adjusted more accurately to meet the different needs of users for the volume of the heating device under different control modes.

[0160] like Figure 6 As shown, specifically, the control method includes:

[0161] Step 302: Receive control commands;

[0162] Step 304: Identify the control command as cooling mode;

[0163] Step 306: Obtain the distance value between the distance sensor and the support frame;

[0164] Step 308: Determine whether the distance between the distance sensor and the support frame is equal to the preset second distance value;

[0165] Step 310: If not, the motor starts and drives the moving part to descend along the rod axis;

[0166] Step 312: If yes, the motor stops.

[0167] In summary, the ingenious design of the heating device lies in:

[0168] First, by configuring a first support assembly, a second support assembly, and a heating assembly, and by defining the connection and movement methods between these components, the heating device, in heating mode, allows the first and second support assemblies to drive the heating assembly to gradually open, increasing the volume of the heating device and thus increasing the heat exchange area between the heating device and the air, thereby improving heating efficiency. In cooling mode, the first and second support assemblies drive the heating assembly to gradually close, reducing the volume of the heating device and thus decreasing the exhaust space it occupies, preventing any impact on airflow and improving cooling efficiency. This helps maintain a stable ambient temperature in places such as computer rooms, data centers, and electronic equipment rooms.

[0169] Secondly, multiple heating elements are designed to be distributed in an umbrella shape along the circumference of the rod. When the moving part moves and drives the first connecting part to rotate relative to the heating elements, the first connecting part can drive the heating elements to rotate relative to the rod. This allows the heating elements to open at an increased angle relative to the rod in heating mode, with the heating device opening in an umbrella shape. In cooling mode, the heating elements to open at a decreased angle relative to the rod, with the heating device closing in a bundle shape. This changes the volume of the heating device to adapt to the needs of different modes.

[0170] Third, a distance sensor is added to the heating device. The distance signal obtained by the distance sensor makes it easier to control the movement direction and stroke of the moving parts, thereby realizing automatic control of the heating device to increase in heating mode and decrease in cooling mode, thus improving the efficiency of temperature regulation in the computer room.
