Technical Field

[0001] This application relates to the field of air conditioning and refrigeration technology, and in particular to a refrigeration regulation method, a heat exchanger, and a heat exchange device. Background Technology

[0002] Special air conditioners are devices designed and manufactured to meet the needs of certain processes and special environments, strictly controlling the temperature, humidity, cleanliness, air pressure, and air speed of the controlled environment within a specific range. They are widely used in key industries such as power, communications, transportation, chemical, metallurgy, machinery, electronics, medical, pharmaceutical, and aerospace.

[0003] Most existing split-type special air conditioning indoor units are based on household indoor units, with changes made to the materials on their original structure and structural adjustments made to installation and maintenance to address the limitations of their installation environment.

[0004] However, compared to the operating environment of household indoor units, special air conditioners operate in harsh environments with complex conditions and high performance requirements. This improvement cannot achieve better cooling performance in harsh environments. Summary of the Invention

[0005] Based on this, this application addresses the problem of poor cooling effect of existing special air conditioners by proposing a cooling regulation method, a heat exchanger, and a heat exchange device.

[0009] If the real-time cooling capacity is not equal to the preset target cooling capacity, adjust the air inlet angle of the heat exchanger's windward side to achieve the air volume corresponding to the target cooling capacity.

[0010] In one embodiment, the preset target cooling capacity is the maximum cooling capacity, and the air intake volume corresponding to the maximum cooling capacity is the area of ​​the windward surface multiplied by the air intake velocity of the windward surface.

[0011] In one embodiment, the step of adjusting the air inlet angle of the heat exchanger's windward side to achieve the air inlet volume corresponding to the target cooling capacity specifically includes:

[0012] Control the air-facing side of the heat exchanger to rotate until the angle between the air-facing side and the air inlet direction is 90 degrees.

[0013] In one embodiment, controlling the rotation of the windward side of the heat exchanger specifically includes:

[0014] Control the rotation of at least one sub-module forming the heat exchanger, wherein each sub-module has an air-facing side.

[0015] In one embodiment, the submodule includes at least two submodules, and the submodules are connected in pairs. Specifically, controlling the rotation of at least one submodule forming the heat exchanger includes:

[0016] Adjust the opening angle between every two connected sub-modules.

[0017] In one embodiment, after adjusting the opening angle between every two connected sub-modules, the method further includes:

[0018] Determine whether the opening / closing angle has reached its limit angle;

[0019] If so, then keep the submodule running in its current state;

[0020] If not, continue adjusting the opening and closing angle.

[0021] In one embodiment, the heat exchanger of the heat exchange device may be an evaporator and / or a condenser.

[0022] According to another aspect of this application, a heat exchanger is also provided for use in a refrigeration system of a heat exchange device, comprising at least one sub-module, each sub-module having an air-facing surface;

[0023] Furthermore, the air intake angle of the windward side of each sub-module is adjustable.

[0024] In one embodiment, the submodule includes a first submodule and a second submodule, the first submodule and the second submodule are connected and the opening angle between them is adjustable;

[0025] Both the side of the first submodule facing away from the second submodule and the side of the second submodule facing away from the first submodule have windward sides.

[0026] In one embodiment, the first submodule and / or the second submodule are rotatable along a set axis to change the opening angle between them, and the set axis intersects with the air intake direction.

[0027] In one embodiment, the heat exchanger further includes a drive assembly that is driven to each submodule and can move the submodule to adjust the air inlet angle of the windward side.

[0028] In one embodiment, the drive assembly includes a connector and a fixed shaft, the connector being connected to a submodule and the connector being rotatably connected to the fixed shaft.

[0029] In one embodiment, the drive assembly includes a drive member that is driven to a connector and is used to drive the connector to drive the submodule to rotate synchronously relative to a fixed axis.

[0030] In one embodiment, the heat exchanger also includes refrigerant pipes, which are arranged in each submodule and interconnected.

[0031] Furthermore, the refrigerant pipes are made of flexible materials.

[0032] In one embodiment, the heat exchanger is an evaporator and / or a condenser.

[0033] According to another aspect of this application, a heat exchange device is also provided, including a controller and a heat exchanger as described in any of the above embodiments, wherein the controller executes the refrigeration regulation method described in any of the above embodiments to adjust the air inlet angle of the windward side of the heat exchanger.

[0034] The above-mentioned cooling regulation method controls the heat exchange equipment by comparing the real-time cooling capacity with the preset target cooling capacity during operation. When the real-time cooling capacity equals the target cooling capacity, it indicates that the cooling effect of the heat exchange equipment just meets the user's requirements. When the real-time cooling capacity does not equal the target cooling capacity, it indicates that the cooling effect of the heat exchange equipment just meets the user's requirements. In this case, the effective heat exchange area is changed by adjusting the angle between the windward side and the air inlet direction, thereby achieving the effective heat exchange area corresponding to the target cooling capacity and ensuring the heat exchange effect of the heat exchange equipment.

[0052] As mentioned in the background technology, special air conditioners are devices designed and manufactured to meet the needs of certain processes and special environments. They are used to strictly control the temperature, humidity, cleanliness, wind pressure, wind speed, etc. of the controlled environment within a specific range. They are generally used in specific and relatively harsh environments. Their heat exchange and cooling effects are greatly affected by external factors. For example, when the outside wind direction or wind speed changes, the air intake of the evaporator and condenser will change accordingly, and the heat exchange effect will change, which will directly affect the cooling effect of the air conditioner, resulting in special air conditioners achieving better cooling effects in harsh environments.

[0053] To address this problem, this application proposes a refrigeration regulation method that can make timely adjustments based on the real-time conditions of the operating environment, such as... Figures 1 to 4 The cooling regulation method specifically includes the following steps:

[0054] S20. Obtain the real-time cooling capacity generated during the operation of the heat exchange equipment;

[0055] The heat exchange equipment can be household air conditioners, commercial air conditioners, special air conditioners, or other air conditioning equipment, or other equipment used to exchange heat with the outside world to reduce the temperature of the outside environment. This application does not limit the scope of the application.

[0056] Specifically, the temperature, pressure, flow rate, and ambient humidity of the evaporator in the refrigeration system of the heat exchange equipment in a cooling state can be obtained. Based on the above parameters, the real-time cooling capacity can be calculated. Alternatively, a dedicated detection device can be connected to the heat exchange equipment in operation. Based on the above parameters, the real-time cooling capacity value or curve can be obtained intuitively through the detection device.

[0057] To obtain various parameters of the evaporator when it is in a cooling state, temperature sensors, pressure sensors, and flow meters can be installed at the inlet and outlet of the evaporator, or thermocouples can be installed on the inlet and outlet pipes of the evaporator to obtain other desired temperature or humidity parameters.

[0058] Understandably, during the operation of heat exchange equipment, the real-time cooling capacity will not change if the external environment remains unchanged and the compressor frequency of the refrigeration system remains constant. However, when the external environment changes abruptly, such as a change in wind direction, temperature, or wind speed, the real-time cooling capacity will also be affected.

[0059] S30. Determine the difference between the real-time cooling capacity and the preset target cooling capacity;

[0060] S. If the real-time cooling capacity is not equal to the preset target cooling capacity, adjust the air inlet angle c of the windward side a of the heat exchanger 100 of the heat exchange equipment to achieve the air inlet volume corresponding to the target cooling capacity.

[0061] The air inlet angle c refers to the angle between the air inlet direction and the air inlet face a of the heat exchanger 100. When the operating environment changes, such as when the air inlet angle c changes, the air inlet velocity will change, which will directly affect the heat exchange capacity of the heat exchanger 100.

[0062] The target cooling capacity can be customized by the user or determined based on the real-time ambient temperature. When the real-time cooling capacity generated by the heat exchange equipment is not equal to the target cooling capacity, it means that the cooling capacity generated by the heat exchange equipment is insufficient or excessive. Since the air velocity in the environment cannot be controlled after the heat exchange equipment is installed, the air inlet angle c is changed to increase or decrease the air inlet volume of the heat exchanger 100.

[0063] Thus, during the operation of the heat exchange equipment, control is performed based on the comparison between the real-time cooling capacity and the preset target cooling capacity. When the real-time cooling capacity equals the target cooling capacity, it indicates that the cooling effect of the heat exchange equipment at this time just meets the user's requirements. When the real-time cooling capacity does not equal the target cooling capacity, it indicates that the cooling effect of the heat exchange equipment at this time does not meet the user's requirements. In this case, the air inlet angle c is adjusted to change the air inlet volume to ensure the heat exchange effect of the heat exchange equipment.

[0064] When it is necessary to improve the cooling effect of the heat exchange equipment, the target cooling capacity can be set to a larger value to ensure that the cooling effect of the heat exchange equipment can be improved. When it is necessary to reduce the cooling effect of the heat exchange equipment, the target cooling capacity can be set to a smaller value to reduce energy consumption and allow the heat exchange equipment to operate under comfortable operating conditions.

[0065] In one embodiment, such as Figure 2 Before step S20, the following are also included:

[0066] Step S10: Set the target cooling value;

[0067] Specifically, the target cooling value is the cooling temperature value set by the user and required to be achieved through the heat exchange equipment. In specific environments, when a constant indoor temperature is required, the cooling system must be controlled to operate at the preset target cooling capacity to maintain the indoor temperature at the target cooling value, in order to avoid excessively low or high indoor temperatures caused by excessively high or low real-time cooling capacity.

[0068] In the hot summer, if the room needs to be cooled, the target cooling value is set to 16°C. The heat exchange equipment generally includes a controller and a cooling system. After receiving the command for the target cooling value, the controller will control the cooling system to start and run the cooling operation, and reduce the indoor temperature to the target cooling value with the preset target cooling capacity.

[0069] In one embodiment, the preset target cooling capacity is the maximum cooling capacity, and the air intake volume corresponding to the maximum cooling capacity is the air intake velocity of the windward side a multiplied by the area of ​​the windward side a.

[0070] At this time, refer to Figure 3 Step S30 is to determine the magnitude of the real-time cooling capacity and the maximum cooling capacity;

[0071] Step S is to adjust the air inlet angle c of the windward side a of the heat exchanger 100 of the heat exchange equipment if the real-time cooling capacity is less than the maximum cooling capacity, so as to achieve the air inlet volume corresponding to the maximum cooling capacity, that is, the air inlet velocity multiplied by the area of ​​the windward side a.

[0072] Maximum cooling capacity refers to the maximum cooling capacity that a heat exchange device can generate in a set environment, which can be obtained through long-term test data during the initial testing phase. When the real-time cooling capacity reaches the maximum cooling capacity, the air intake is at its maximum, and all areas of the windward side a are effectively heat-exchanged, enabling the heat exchange device to achieve rapid cooling.

[0073] In one embodiment, when the target cooling capacity is the maximum cooling capacity, step S specifically includes:

[0074] S41. Control the windward face a of heat exchanger 100 to rotate until the angle between the windward face a and the air inlet direction is 90°.

[0075] At this point, it is equivalent to the air entering vertically from the windward side a of heat exchanger 100. All areas of the windward side a are effectively heat exchanged, and the effective heat exchange area is equal to the area of ​​the windward side a, thus increasing the air intake.

[0076] When the real-time cooling capacity does not reach the maximum cooling capacity, the effective heat exchange area of ​​the heat exchanger 100 is smaller than the area of ​​the windward side a, the air intake is small, the cooling effect is insufficient, and rapid cooling cannot be achieved. By controlling the change of the air intake angle c, the effective heat exchange area is increased and the air intake is increased, so as to improve the heat exchange effect of the heat exchange equipment.

[0077] Thus, by adjusting the air inlet angle c of the windward surface a, making the windward surface a perpendicular to the air inlet direction, the air inlet volume is increased, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0078] In one embodiment, controlling the rotation of the windward side a of the heat exchange surface in step S41 specifically includes:

[0079] S411. Control at least one sub-module forming the heat exchanger 100 to rotate, wherein each sub-module has an air-facing surface a.

[0080] The heat exchanger 100 includes at least one sub-module. Each sub-module can exchange heat with the outside through the windward surface a. By controlling the rotation of the sub-module, the air inlet direction remains unchanged. The rotation of the sub-module causes the air inlet direction and the air inlet angle c generated by the windward surface a to change.

[0081] In this way, the rotation of the heat exchanger 100 itself can be controlled to match the air intake direction in harsh environments. When the air intake direction changes, the rotation of the heat exchanger 100 is controlled accordingly to ensure that the windward side a is vertically inlet, so that the heat exchanger 100 always maintains the maximum air intake during operation.

[0082] Specifically, the heat exchanger 100 also includes a drive assembly, which is connected to the sub-module and can drive each sub-module to rotate, thereby adjusting the windward surface a. The specific connection method is detailed below.

[0083] Specifically, the sub-modules forming the heat exchanger 100 may include one or more. When there is only one sub-module, a drive component is connected to the sub-module and drives it to rotate within the heat exchanger, thereby adjusting the air inlet angle c of the windward surface a. When there are multiple sub-modules, the angle of each sub-module within the heat exchanger is adjustable, thereby adjusting the air inlet angle c of multiple windward surfaces a.

[0084] In one embodiment, the sub-module includes at least two sub-modules, and the sub-modules are connected in pairs. The step S411 of controlling the rotation of at least one sub-module forming the heat exchanger 100 specifically includes: S4111, adjusting the opening angle b between each pair of connected sub-modules.

[0085] Specifically, for example, the submodule may include a first submodule 10 and a second submodule 20, the first submodule 10 and the second submodule 20 are connected, and the sides of the first submodule 10 and the second submodule 20 that are opposite to each other form a windward surface a, at which time the heat exchanger 100 can achieve double-sided air intake.

[0086] When it is necessary to change the air intake angle c of the windward surface a, the opening and closing angle b between the first sub-module 10 and the second sub-module 20 is adjusted to achieve the rotation of the first sub-module 10 relative to the second sub-module 20. Since the first sub-module 10 and the second sub-module 20 themselves rotate, the windward surface a on them also rotates, and the air intake angle c of the windward surface a changes accordingly.

[0087] Understandably, the submodule may also include a third submodule 30 or others. The third submodule 30 is located at the end of the first submodule 10 away from the second submodule 20 and is connected to the first submodule 10. Furthermore, the opening angle b between the first submodule 10 and the third submodule 30 is adjustable. The third submodule 30 has a windward surface a, thereby adjusting the air intake angle of the windward surface a of the third submodule 30, and so on. This application will not elaborate further here.

[0088] In one embodiment, after adjusting the opening angle b between the two intersecting sub-modules, the following is also included:

[0089] S50. Determine whether the opening / closing angle b has reached the limit angle.

[0090] S60. If so, then maintain the current state.

[0091] S70. If not, continue to adjust the opening angle b until the air intake angle c of the windward side a is 90 degrees.

[0092] For example, when the first submodule 10 and the second submodule 20 form a "V"-shaped connection, if the air inlet angle c needs to be adjusted to 90 degrees, the size of the "V"-shaped opening changes with the opening angle b. The first submodule 10 and the second submodule 20 can rotate relative to each other until the "V"-shaped opening is at its minimum state or the "V"-shaped opening is at its maximum state.

[0093] For example, when the first submodule 10 and the second submodule 20 are rotated relative to each other until the "V"-shaped opening is at its minimum, the opening angle b between the first submodule 10 and the second submodule 20 needs to be as small as possible, for example, the limit angle is set to 5 degrees-10 degrees, so that the first submodule 10 and the second submodule 20 are close to the fit. If the windward side a cannot be vertically air-intake at this time, the submodule is controlled to operate in the current state to achieve the best air intake volume without damaging the heat exchanger 100.

[0094] The limit angle refers to the limit value of the opening angle b formed by the connection between the first submodule 10 and the second submodule 20. It can be understood that it can be the maximum or minimum value. When the first submodule 10 and the second submodule 20 move closer or further away from each other to the point that they can no longer rotate relative to each other, the opening angle b can no longer be reduced or expanded. Therefore, it can only ensure that the submodule operates in its current state.

[0095] Specifically, in one embodiment, when the limiting angle is the minimum angle, the first submodule 10 and the second submodule 20 form a "V"-shaped connection. The side of the first submodule 10 away from the second submodule 20 forms a windward surface a, and the side of the second submodule 20 away from the first submodule 10 also forms a windward surface a. The opening angle b between the first submodule 10 and the second submodule 20 is controlled to be as small as possible to adjust the air intake angle c towards 90 degrees. At this time, there are two ending states:

[0096] 1) When the air inlet angle c of the air inlet surface reaches 90 degrees, stop adjusting and control the first sub-module 10 and the second sub-module 20 to exchange heat in the current state;

[0097] 2) When the air inlet angle c of the air inlet surface does not reach 90 degrees, the opening and closing angle b reaches the limit angle. At this time, the first sub-module 10 and the second sub-module 20 can no longer continue to move relative to each other. Within the adjustable range of the heat exchanger 100, the most suitable state can be found and heat exchange can be performed in the current state.

[0098] In one embodiment, step S20, obtaining the real-time cooling capacity generated during the operation of the heat exchange equipment, specifically includes:

[0099] Step S21: Obtain the running parameters, including q mi Heat exchanger 100 air inlet volume, c pa Specific heat capacity of intake air, t a1 Inlet air temperature, t a2 Air outlet temperature, v' n The specific volume of the humid air outlet from the heat exchanger, w n Humidity of the air outlet from the heat exchange equipment;

[0100] Step S22: Calculate the real-time cooling capacity Q sci :

[0101]

[0102] According to the formula for calculating real-time cooling capacity, once the cooling environment of the heat exchange equipment is determined, then c pa v' n w n Confirmed, at this time the heat exchanger inlet air volume q is 100. mi The larger the value, the greater the real-time cooling capacity. Thus, the real-time cooling capacity can be obtained through this formula during the operation of the heat exchange equipment.

[0103] Understandably, the maximum cooling capacity can also be obtained through this formula in the early testing phase, thereby setting the target cooling capacity in advance so as to compare the real-time cooling capacity with the maximum cooling capacity during the operation of the heat exchange equipment.

[0104] Specifically, q mi =F*V, F=S max *sinc;

[0105] Among them, S max Let be the area of ​​the windward surface a, c be the air inlet angle c of the windward surface a, V be the air inlet velocity of the windward surface a, and F be the effective heat exchange area.

[0106] Understandably, when c approaches 90 degrees, the air intake angle c is nearly vertical, and cosc ​​approaches 1. At this point, F is approximately equal to the area S of the windward surface a. max The effective heat exchange area F is the largest.

[0107] When c is less than 90 degrees, the air intake angle c is an acute angle, cosc ​​is less than 1, and F is less than S. max The effective heat exchange area F is only the area S of the windward side a. max Part of it.

[0108] In this way, by adjusting to ensure that the air intake angle c of the windward side a is vertical, the air intake volume is increased, thereby increasing the cooling capacity.

[0109] Furthermore, the heat exchanger 100 of the heat exchange equipment can be an evaporator or a condenser, thereby improving the cooling effect of the heat exchange equipment by improving the heat exchange effect of the two heat exchangers.

[0110] According to another aspect of this application, a heat exchanger 100 is also provided, which is applied in the refrigeration system of the heat exchange equipment, wherein the heat exchanger 100 exchanges heat to achieve refrigeration of the refrigeration system.

[0111] Specifically, such as Figures 1 to 3 The heat exchanger 100 includes at least one sub-module, each sub-module having an air-facing surface a, and the air inlet angle c of the air-facing surface a of each sub-module is adjustable.

[0112] The heat exchanger 100 may include one or more sub-modules, all of which are capable of heat exchange. The air inlet angle c of each air inlet surface a is changed by adjusting the windward surface a formed by each sub-module.

[0113] Understandably, during the operation of a heat exchanger, assuming the external environment remains constant and the compressor frequency of the refrigeration system remains constant, the cooling capacity of the heat exchanger will not change. However, when the external environment changes abruptly, such as a change in wind direction, temperature, or wind speed, the cooling capacity of the heat exchanger will be affected. For example, when the inlet air direction changes, the inlet angle c of the heat exchanger 100 changes, the corresponding inlet air volume also changes, and thus the cooling capacity of the heat exchanger also changes.

[0114] During the operation of the heat exchange equipment, the real-time cooling capacity of the heat exchange equipment can be adjusted to the target cooling capacity required by the customer by adjusting the air inlet angle c of the windward side a. For example, when it is necessary to improve the cooling effect of the heat exchange equipment, the air inlet angle c can be adjusted to be vertical to increase the air volume and thus improve the cooling effect of the heat exchange equipment. When it is necessary to control the cooling effect to decrease, the air inlet angle c can be reduced to an acute angle to decrease the air volume and thus reduce the cooling effect of the heat exchange equipment.

[0115] Thus, the heat exchanger 100 provided in this application can change the cooling effect of the heat exchange equipment by changing the air inlet angle c, so as to achieve the target cooling capacity.

[0116] In one embodiment, if the goal is to achieve rapid cooling in a certain environment, the target cooling capacity can be set as the maximum cooling capacity. The maximum cooling capacity refers to the maximum cooling capacity that the heat exchange device can generate in the set environment, which can be obtained through long-term test data during the early testing process.

[0117] When the real-time cooling capacity reaches the maximum cooling capacity, the air intake corresponding to the maximum cooling capacity is the area of ​​the windward surface a multiplied by the air intake velocity of the windward surface a. The air intake reaches the maximum, thereby achieving rapid cooling.

[0118] Specifically, at this time, the windward face a of the heat exchanger 100 is rotated until the angle between the windward face a and the air inlet direction is 90°. This is equivalent to the windward face a of the heat exchanger 100 being perpendicular to the air inlet, and all areas of the windward face a are effectively heat exchanged. The effective heat exchange area is equal to the area of ​​the windward face a, and the air inlet volume increases.

[0119] When the real-time cooling capacity does not reach the maximum cooling capacity, the effective heat exchange area of ​​the heat exchanger 100 is smaller than the area of ​​the windward surface a. The air intake is small, the cooling effect is insufficient, and rapid cooling cannot be achieved. By controlling the change of the air intake angle c, the effective heat exchange area is increased to be equal to the area of ​​the windward surface a, so as to increase the air intake and improve the heat exchange effect of the heat exchange equipment.

[0120] Therefore, if it is necessary to enhance the heat exchange effect, the angle of the windward surface a can be adjusted so that the windward surface a is perpendicular to the air inlet direction, thereby increasing the air inlet volume and thus improving the heat exchange efficiency of the heat exchanger 100.

[0121] In one embodiment, such as Figures 1 to 3 The submodule includes a first submodule 10 and a second submodule 20. The first submodule 10 and the second submodule 20 are connected and the opening angle b between them is adjustable. The side of the first submodule 10 facing away from the second submodule 20 and the side of the second submodule 20 facing away from the first submodule 10 both have a windward surface a.

[0122] At this time, the heat exchanger 100 can achieve double-sided air intake. When it is necessary to change the air intake angle c of the windward surface a, the rotation of the first sub-module 10 relative to the second sub-module 20 is achieved by adjusting the opening and closing angle b between the first sub-module 10 and the second sub-module 20. The rotation of the second sub-module 20 relative to the first sub-module 10, since the first sub-module 10 and the second sub-module 20 themselves have rotated, the windward surface a on them has also rotated. At this time, the air intake angle c of the windward surface a changes accordingly.

[0123] In one embodiment, the first submodule 10 and / or the second submodule 20 are rotatable along a set axis to change the opening angle b between them, and the set axis intersects with the air intake direction.

[0124] The set axis can be formed at the end where the first sub-module 10 and the second sub-module 20 are connected, or it can be formed at other parts. For example, when the first sub-module 10 and the second sub-module 20 form a "V" or inverted "V" shaped connection structure, the first sub-module 10 and the second sub-module 20 on both sides are controlled to rotate around the tip of the "V" as the set axis. Thus, when rotating, the air inlet angle c of the air inlet surface on both sides is changed, which facilitates the adjustment of the air inlet volume of the heat exchanger 100.

[0125] In other embodiments, the submodule may also include others, such as Figures 1 to 3 The third submodule 30 is located at the end of the first submodule 10 furthest from the second submodule 20. The third submodule 30 has a windward surface a on its side facing away from the first submodule 10. The third submodule 30 is connected to the first submodule 10, and the opening angle b between them is adjustable. Through the arrangement of the first submodule 10, the second submodule 20, and the third submodule 30, multi-faceted air intake can be achieved in the heat exchanger 100, thereby increasing the total area of ​​the windward surface a of the heat exchanger 100.

[0126] In one embodiment, the heat exchanger 100 further includes a drive assembly that is driven to each submodule and capable of moving the submodule to adjust the air inlet angle c of the windward surface a.

[0127] The drive assembly may include a drive motor, cylinder and other power structures, which are driven and connected to each sub-module and drive the connected sub-module to move, thereby adjusting the position of the windward surface a, and thus automatically adjusting the air inlet angle c, so that the heat exchanger 100 can be automated.

[0128] In actual operation of the heat exchange equipment, if insufficient real-time cooling capacity is detected, the controller of the heat exchange equipment can issue an activation command to control the drive component to drive the windward surface a on the corresponding sub-module to rotate, thereby increasing the air intake and improving the cooling effect to achieve rapid cooling.

[0129] In one embodiment, the drive assembly includes a connector 42 and a fixed shaft 43. The connector 42 is connected to the sub-module, and the connecting portion is rotatably connected to the fixed shaft 43. The connector 42 can drive the sub-module connected to it to rotate circumferentially relative to the fixed shaft 43, thereby adjusting the air intake angle c of the windward surface a on the sub-module.

[0130] The connector 42 can be a connecting rod or a connecting plate, etc. It is sleeved on the fixed shaft 43 and can move in a circular motion relative to the fixed shaft 43 to facilitate the position adjustment of the sub-module.

[0131] Specifically, when the submodule includes a first submodule 10 and a second submodule 20, the connector 42 includes a first connecting part 422 and a second connecting part 423. The first connecting part 422 is connected to the first submodule 10, and the second connecting part 423 is connected to the second submodule 20. Both the first connecting part 422 and the second connecting part 423 are rotatably connected to the fixed shaft 43, thus forming a hinge between the connecting parts and the fixed connection. When it is necessary to control the rotation angle of the windward surface a on the first submodule 10, the first connecting part 422 is controlled to rotate relative to the fixed shaft 43. Similarly, when it is necessary to control the rotation angle of the windward surface a on the second submodule 20, the second connecting part 423 is controlled to rotate relative to the fixed shaft 43.

[0132] In one embodiment, the drive assembly includes a drive member 41, which is driven to connect with a connector 42 and is used to drive the connector to rotate synchronously with the submodule relative to the fixed shaft 43. The drive member 41 can be a drive motor, cylinder or other power structure. It is driven to connect with the connector 42 and drives the connector 42 to rotate relative to the fixed shaft 43, so as to realize the automatic adjustment of the windward angle on the submodule.

[0133] In one embodiment, the heat exchanger 100 further includes refrigerant pipes 50, which are arranged in each submodule and interconnected, and the refrigerant pipes 50 are made of a flexible material.

[0134] Since the sub-modules of the heat exchanger 100 of this application are at risk of displacement, the metal steel pipes that flow the refrigerant in the conventional heat exchanger 100 cannot adapt to the displacement of the sub-modules. Therefore, this application sets the pipes that flow the refrigerant in the heat exchanger 100 to be made of flexible material. When the sub-modules rotate or move, the refrigerant pipes 50 connecting the two sub-modules will twist accordingly, avoiding the risk of the refrigerant pipes 50 being damaged.

[0135] In one embodiment, the connection between the connector 42 and the fixed shaft 43 in this application can also be locked. In different types of heat exchange equipment, due to the different reserved space inside, the opening and closing angle b of multiple sub-modules can be adjusted and then locked to achieve compatibility with different types of heat exchange equipment, realize the purpose of one thing serving multiple purposes, and effectively reduce production and maintenance costs.

[0136] Specifically, the heat exchanger 100 provided in this application can be used as a condenser of a heat exchange device, or as an evaporator of a heat exchange device, or can simultaneously form a condenser and an evaporator to improve the heat exchange effect of the heat exchange device.

[0137] According to another aspect of this application, a heat exchange device is also provided, including a controller and the controller of any of the above. The controller executes the refrigeration regulation method of any of the above to adjust the air inlet angle c of the windward surface a in the heat exchanger 100 of any of the above. Since the heat exchange device uses the refrigeration regulation method provided in any of the above embodiments for refrigeration regulation, it has the same technical effect as the refrigeration regulation method described above.

[0138] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0139] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
