Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
An air conditioner and a heat dissipating device thereof according to an embodiment of the present utility model are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a heat dissipating device of an air conditioner according to an embodiment of the present utility model. Referring to fig. 1, a heat dissipating device 100 of an air conditioner may include: a heat radiation fan 110 and a thermoelectric generation member 120.
Wherein, the heat radiation fan 110 is configured to radiate heat to a part to be radiated of the air conditioner; the thermoelectric generation element 120 has a hot end and a cold end, the hot end is disposed corresponding to the element to be cooled to absorb heat of the element to be cooled, the cold end is used to absorb cold, and the thermoelectric generation element 120 is configured to generate a voltage based on a temperature difference between the heat and the cold to supply power to the cooling fan 110 so as to operate the cooling fan 110.
Specifically, the heat dissipation parts of the air conditioner include, but are not limited to, power switch tubes, bus capacitors, inductors and the like for driving the compressor to work, and the heat dissipation parts are not limited herein.
The thermoelectric generation member 120 refers to a device that generates a voltage using the seebeck effect, which is a thermoelectric phenomenon that causes a voltage difference between two substances due to a temperature difference of two different electric conductors or semiconductors, and is also called a first thermal effect. The specific structure of the thermoelectric generation element 120 is not limited here.
Illustratively, referring to FIG. 2, thermoelectric generation element 120 includes a hot side 121, a cold side 122, a P-type semiconductor 123, and an N-type semiconductor 124, hot side 121 includes a base plate 1211 and a deflector strip 1212, and cold side 122 includes two deflector strips 1221 and 1222 and a base plate 1223. The substrate 1211 may be disposed adjacent to the heat dissipation member to absorb heat generated by the heat dissipation member, the substrate 1223 may absorb cold energy of the surrounding environment, so that one end of the P-type semiconductor 123 and one end of the N-type semiconductor 124 are placed in a high temperature environment, and the other end of the P-type semiconductor 123 is placed in a low temperature environment, and under the excitation of heat, the hole concentration of the high temperature end of the P-type semiconductor 123 is higher than that of the low temperature end, and the electron concentration of the high temperature end of the N-type semiconductor 124 is higher than that of the low temperature end, so that the hole and the electron flow start to diffuse to the low temperature end under the driving of the concentration gradient, thereby forming electromotive force. Since the electromotive force generated by a single PN junction formed by the P-type semiconductor 123 and the N-type semiconductor 124 is small, a high voltage may be generated by connecting a plurality of PN junctions in series to supply power to the heat radiation fan 110.
In the operation process of the air conditioner, the heat to be dissipated will generate heat, and as the heat increases, the thermoelectric generation element 120 will generate voltage to supply power to the heat dissipation fan 110, and the heat dissipation fan 110 works to dissipate heat to the heat to be dissipated. It should be noted that, the rotation speed of the cooling fan 110 is positively related to the power supply voltage, the higher the power supply voltage is, the higher the corresponding rotation speed is, the higher the heat dissipation capability is, so, the higher the waste heat of the heat dissipation member is, the higher the heat dissipation capability of the cooling fan 110 is, and the insufficient heat dissipation is avoided, thereby not only improving the operation reliability of the air conditioner, but also not reducing the heat exchange capability of the air conditioner, for example, reducing the operation frequency of the compressor, so that the air conditioner operates with higher performance, and meanwhile, the heat dissipation capability of the heat dissipation member is self-adaptively adjusted according to the environmental conditions, so that the heat dissipation capability waste can be avoided, and the whole heat dissipation process is not additionally controlled.
In the above embodiment, based on the thermoelectric power generation piece, the electric energy is generated by utilizing the temperature difference between the waste heat of the piece to be radiated and the surrounding environment, so that the cooling fan is driven to work, and the heat dissipation capacity of the piece to be radiated can be adaptively adjusted according to the environmental working condition under the condition of no additional control, thereby avoiding the waste or insufficient heat dissipation capacity.
In some embodiments, the cold end of thermoelectric generator 120 is positioned opposite the air intake side of the air conditioner.
Referring to fig. 3, an air conditioner may include an outdoor unit 200, the outdoor unit 200 includes an electric control box assembly 210 and an outdoor fan 220, and a heat dissipation fan 110 is disposed corresponding to the electric control box assembly 210 for dissipating heat from devices in the electric control box assembly 210, such as a power switch tube IGBI (Insulated Gate Bipolar Transistor ), an IPM (INTELLIGENT POWER MODULE, intelligent power module) and the like. The hot end 121 of the thermoelectric power generation element 120 is arranged corresponding to devices in the electric control box assembly 210, the cold end 122 of the thermoelectric power generation element 120 is arranged corresponding to the air inlet side of the outdoor unit 200, and can be specifically arranged corresponding to the outdoor fan 220, and the cold end of the thermoelectric power generation element 120 is connected with the power supply end of the cooling fan 110 through the connecting wire 230 and the wire holder 240 so as to supply power to the cooling fan 110. In the operation process of the air conditioner, a voltage is generated by the thermoelectric generation member 120 based on a temperature difference between the heat of the member to be cooled and the cooling capacity of the outdoor fan 220 side, so as to supply power to the cooling fan 110, and the member to be cooled is cooled by the cooling fan 110.
Therefore, the electric energy generated by the waste heat generated by the heat-to-be-radiated part of the air conditioner is utilized according to the thermoelectric generation part to drive the heat radiation fan to work, the temperature of the heat-to-be-radiated part is reduced, and the reliability of the control system of the air conditioner is enhanced.
In some embodiments, referring to fig. 4, the heat dissipating device 100 of the air conditioner further includes: the first switch K1 is connected in series to the power supply circuit between the thermoelectric generation element 120 and the cooling fan 110, and the first switch K1 is configured to control the power supply circuit to be turned on or off.
For example, after the air conditioner is started up and is operating normally, the temperature Tm of the member to be cooled may be detected by a temperature sensor configured on the member to be cooled, and then determined. If the temperature Tm of the to-be-cooled member is less than or equal to the first preset temperature threshold tm_min, it indicates that the current temperature of the to-be-cooled member is low, and at this time, the first switch K1 is kept in an off state, so that a natural cooling mode is adopted for cooling, and no additional cooling measures are required. If the temperature Tm of the to-be-cooled member is greater than the first preset temperature threshold tm_min, it is indicated that the temperature of the to-be-cooled member is increased, and the first switch K1 is controlled to be in the closed state at this time, so as to use an additional cooling mode to cool, that is, the temperature difference generating member 120 drives the cooling fan 110 to work based on the voltage generated by the seebeck effect, so as to drive the air to enhance the cooling of the to-be-cooled member. Wherein, tm_min is determined according to practical conditions, and is not limited herein.
Therefore, the first switch is controlled based on the temperature of the part to be cooled, so that when the temperature of the part to be cooled is high, the voltage generated by the thermoelectric generation part based on the Seebeck effect drives the cooling fan to work, and the heat dissipation capacity of the part to be cooled is effectively improved.
In some embodiments, referring to fig. 5, the heat dissipating device 100 of the air conditioner further includes: the first voltage source 130 is selectively connected in series with the thermoelectric generator 120, wherein the first voltage source 130 and the thermoelectric generator 120 jointly supply power to the cooling fan 110 when the first voltage source 130 is connected in series with the thermoelectric generator 120.
Further, with continued reference to fig. 5, the heat dissipating device 100 of the air conditioner further includes: the second switch K2, the second switch K2 is connected in parallel with the first voltage source 130, the second switch K2 is configured to control the first voltage source 130 to be connected in series with the thermoelectric generator 120 or to short the first voltage source 130.
Specifically, after the air conditioner is started and normally operates, if the temperature Tm of the part to be cooled is less than or equal to the first preset temperature threshold tm_min, the first switch K1 is kept in an open state, and the second switch K2 is kept in a closed state, so that heat is dissipated in a natural heat dissipation mode, and no additional heat dissipation measures are needed. If the temperature Tm of the heat dissipation member is greater than the first preset temperature threshold tm_min and less than or equal to the second preset temperature threshold tm_mid, the first switch K1 is controlled to be in a closed state so as to dissipate heat in an additional heat dissipation mode, that is, the heat dissipation fan 110 is driven to work by the voltage generated by the thermoelectric generation member 120 based on the seebeck effect, so as to dissipate heat of the heat dissipation member. After entering the additional heat dissipation mode, the voltage generated by the thermoelectric generation element 120 may be insufficient, the heat dissipation fan 110 operates at a lower rotation speed, the heat dissipation effect is poor, the temperature of the heat dissipation element continues to rise, and when the temperature Tm of the heat dissipation element is greater than the second preset temperature threshold tm_mid and less than or equal to the third preset temperature threshold tm_high, the second switch K2 is controlled to be turned off, so that the heat dissipation in the additional heat dissipation mode is enhanced, that is, after the voltage of the first voltage source 130 and the voltage generated by the thermoelectric generation element 120 are overlapped, the heat dissipation fan 110 is powered, so that the rotation speed of the heat dissipation fan 110 is increased, and the heat dissipation capability is improved.
It should be noted that, after entering the additional heat dissipation enhancing mode, if the temperature of the member to be cooled still continues to increase, when the temperature Tm of the member to be cooled is greater than the third preset temperature threshold tm_high and less than or equal to the fourth preset temperature threshold tm_max, the operation frequency of the compressor in the air conditioner is controlled to decrease, that is, the operation frequency enters the frequency control mode, so as to ensure the reliability of the system; when the temperature Tm of the heat dissipation member is greater than the fourth preset temperature threshold tm_max, the compressor is controlled to stop, the rotation speed of the outdoor fan 220 is started to the maximum allowable rotation speed, and the heat dissipation member is stopped after the first preset time, that is, the heat dissipation member enters a stop control mode, so that the reliability of the system is ensured.
It should be noted that, when the output voltage of the first voltage source 130 is adjustable, the operation frequency of the compressor in the air conditioner may be controlled to be reduced, that is, the operation frequency is controlled to enter the frequency control mode, when the temperature Tm of the heat dissipation member is greater than the third preset temperature threshold tm_high and less than or equal to the fourth preset temperature threshold tm_max, or the output voltage of the first voltage source 130 is greater than the preset voltage threshold, so as to ensure the reliability of the system.
Therefore, when the heat exchange load is large, the first voltage source and the thermoelectric power generation piece jointly drive the heat dissipation fan to work, so that the heat dissipation capacity can be improved, the frequency reduction interval and the frequency reduction time point can be further delayed, and the heat exchange capacity of the air conditioner, such as high-temperature refrigerating capacity, can be improved; in addition, when the heat exchange load is extremely high, the frequency can be reduced or the machine can be stopped, and meanwhile, the rotating speed of the outdoor fan can be increased, so that the reliability of the parts to be cooled and the system can be ensured.
In some embodiments, referring to fig. 6, the heat dissipating device 100 of the air conditioner further includes: the current source 140 is optionally connected in parallel with the cooling fan 110, wherein the current source 140 and the thermoelectric generation element 120 jointly supply power to the cooling fan 110 when the current source 140 is connected in parallel with the thermoelectric generation element 120.
Further, with continued reference to fig. 6, the heat dissipating device 100 of the air conditioner further includes: the third switch K3, the third switch K3 is connected in series with the current source 140, and the third switch K3 is configured to control the current source 140 to be connected in parallel with the heat dissipation fan 110 or to disconnect the current source 140.
Specifically, after the air conditioner is started and normally operates, if the temperature Tm of the part to be cooled is less than or equal to the first preset temperature threshold tm_min, the first switch K1 is kept in an off state, and the third switch K3 is kept in an off state, so that heat is dissipated in a natural heat dissipation mode, and no additional heat dissipation measures are needed. If the temperature Tm of the heat dissipation member is greater than the first preset temperature threshold tm_min and less than or equal to the second preset temperature threshold tm_mid, the first switch K1 is controlled to be in a closed state so as to dissipate heat in an additional heat dissipation mode, that is, the heat dissipation fan 110 is driven to work by the voltage generated by the thermoelectric generation member 120 based on the seebeck effect, so as to dissipate heat of the heat dissipation member. After entering the additional heat dissipation mode, the voltage generated by the thermoelectric generation element 120 may be insufficient, the heat dissipation fan 110 operates at a lower rotation speed, the heat dissipation effect is poor, the temperature of the heat dissipation element continues to rise, when the temperature Tm of the heat dissipation element is greater than the second preset temperature threshold tm_mid and less than or equal to the third preset temperature threshold tm_high, the third switch K3 is controlled to be closed, so that the heat dissipation in the additional heat dissipation mode is enhanced, that is, after the current of the current source 140 and the current generated by the thermoelectric generation element 120 are overlapped, the heat dissipation fan 110 is powered, so that the rotation speed of the heat dissipation fan 110 is increased, and the heat dissipation capability is improved.
It should be noted that, after entering the additional heat dissipation enhancing mode, if the temperature of the member to be cooled still continues to increase, when the temperature Tm of the member to be cooled is greater than the third preset temperature threshold tm_high and less than or equal to the fourth preset temperature threshold tm_max, the operation frequency of the compressor in the air conditioner is controlled to decrease, that is, the operation frequency enters the frequency control mode, so as to ensure the reliability of the system; when the temperature Tm of the heat dissipation member is greater than the fourth preset temperature threshold tm_max, the compressor is controlled to stop, the rotation speed of the outdoor fan 220 is started to the maximum allowable rotation speed, and the heat dissipation member is stopped after the first preset time, that is, the heat dissipation member enters a stop control mode, so that the reliability of the system is ensured.
It should be noted that, when the output current of the current source 140 is adjustable, the operation frequency of the compressor in the air conditioner may be controlled to be reduced, i.e. the compressor enters the frequency control mode, when the temperature Tm of the heat dissipation member is greater than the third preset temperature threshold tm_high and less than or equal to the fourth preset temperature threshold tm_max, or the output current of the current source 140 is greater than the preset current threshold, so as to ensure the reliability of the system.
Therefore, when the heat exchange load is large, the heat radiation fan is driven to work together by the current source and the thermoelectric power generation piece, so that the heat radiation capacity can be improved, the frequency reduction interval and the frequency reduction time point can be delayed, and the heat exchange capacity of the air conditioner, such as high-temperature refrigerating capacity, can be improved; in addition, when the heat exchange load is extremely high, the frequency can be reduced or the machine can be stopped, and meanwhile, the rotating speed of the outdoor fan can be increased, so that the reliability of the parts to be cooled and the system can be ensured.
In some embodiments, current source 140 includes: the second voltage source and the resistive load (not shown) are connected in series, that is, the current source is obtained by connecting the voltage source and the resistive load in series.
