Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, and more particularly to a radiator anti-condensation device and an air conditioner. Background Technology

[0002] Variable frequency compression refrigeration cycle systems commonly use IPM (Intelligent Power Module) modules for frequency conversion control. During IPM operation, significant heat generation occurs. As the heat generated by the IPM modules increases, the demand for heat dissipation also rises. Commonly available intelligent power modules have poor thermal dissipation performance and small heat capacity. At the moment of startup, the chips (such as IGBT, FRD, or MOS chips) generate substantial heat, potentially leading to chip damage. The heat generation of intelligent power modules changes in real time, and currently, there are few methods for precise control of the IPM module coolant. This results in condensation forming on the heat sink surface when the IPM module's surface temperature is below the air dew point, posing a safety hazard to the circuitry.

[0003] The existing solution involves placing the control board radiator between the condenser and the throttling component. This method prevents condensation during cooling, but during heating, the refrigerant temperature is low after throttling, causing the module board temperature to drop below the dew point of the air, resulting in condensation. Condensation can cause circuit board failure or damage, affecting the lifespan of the control system. The mainstream solution to this problem is to add another throttling component, using different throttling components for cooling and heating. This ensures that the module board radiator is always before throttling. However, this requires two throttling components, resulting in high cost, complex control, and low reliability. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0034] In the description of the embodiments of the present invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0036] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0037] The following is combined Figures 1 to 8 The embodiments of the present invention will be described below. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute a limitation thereof.

[0038] like Figures 1 to 4 As shown, the present invention provides a radiator anti-condensation device, including: a heat exchange system 100 and a temperature control circuit 200. The heat exchange system 100 includes a radiator 110. The temperature control circuit 200 is connected to the heat exchange system 100 to circulate part of the heat exchange medium. The temperature control circuit 200 heats the radiator 110 through the heat exchange medium.

[0039] In other words, the temperature control loop 200 draws out a portion of the heat exchange medium from the heat exchange system 100, conducts heat exchange in the radiator 110 to raise the temperature of the radiator 110, and then flows back to the heat exchange system 100. In other words, the temperature control loop 200 is a branch of the heat exchange system 100, allowing the high-temperature heat exchange medium to conduct heat exchange in the radiator 110, thereby controlling the temperature of the radiator 110 and preventing condensation from forming when the temperature of the radiator 110 falls below the ambient temperature.

[0040] The temperature control circuit 200 uses the heat exchange medium of the heat exchange system 100 itself to heat the radiator 110. There is no additional heat source, the structure is simple, the cost is reduced, and the reliability is high.

[0041] Continue to refer to Figures 1 to 4In one embodiment of the present invention, the temperature control circuit 200 includes a flow regulating device 202 for controlling the flow rate of the heat exchange medium entering the temperature control circuit 200. That is, the flow regulating device 202 controls the flow rate of the heat exchange medium entering the temperature control circuit 200, thereby preventing excessive heat exchange medium from entering the temperature control circuit 200 and affecting the working efficiency of the heat exchange system 100.

[0042] The flow regulating device 202 can be a throttle valve or a flow regulating structure with a throttle orifice.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the flow regulating device 202 can be installed at the outlet of the radiator 110. For example... Figure 3 As shown, the flow regulating device 202 can be installed at the inlet of the radiator 110.

[0044] Furthermore, in other embodiments of the present invention, the temperature control circuit 200 includes a switching valve 201, which is used to control the switching of the temperature control circuit 200. For example, the switching valve 201 is a solenoid valve, which can be automatically controlled by an electrical signal.

[0045] When the temperature of radiator 110 is lower than the ambient temperature, the switching valve 201 opens, and the temperature control circuit 200 introduces the high-temperature heat exchange medium from the heat exchange system 100 into the radiator 110 to heat it. When the temperature of radiator 110 is greater than or equal to the ambient temperature, the switching valve 201 closes. The opening and closing state of the switching valve 201 is precisely determined by the temperature.

[0046] The switching valve 201 is located at the inlet of the radiator 110 and can be placed before or after the flow regulating device 202.

[0047] like Figure 1 As shown, in a specific embodiment of the present invention, the radiator anti-condensation device further includes a first temperature sensor 203, which is disposed on the radiator 110 and is communicatively connected to the switching valve 201.

[0048] Specifically, based on the temperature value of the first temperature sensor 203, the opening and closing of the switching valve 201 is controlled, thereby controlling the on / off state of the temperature control circuit 200 to regulate the temperature of the radiator 110 so that the temperature of the radiator 110 is greater than or equal to the ambient temperature.

[0049] For example, a second temperature sensor 111 is provided in the external environment. Both the first temperature sensor 203 and the second temperature sensor 111 are connected to the control unit 112. The control unit 112 receives the first temperature value of the first temperature sensor 203 and the second temperature value of the second temperature sensor 111. Based on the comparison result of the first temperature value and the second temperature value, the control unit 112 controls the opening and closing of the switching valve 201.

[0050] Furthermore, in some embodiments of the present invention, the medium inlet of the temperature control circuit 200 is connected to the outlet of the compressor 101 of the heat exchange system 100, and the medium outlet of the temperature control circuit 200 is connected to the pipeline of the heat exchange system 100.

[0051] Specifically, the temperature control circuit 200 uses the high-temperature and high-pressure heat exchange medium at the outlet of the compressor 101 as the heat exchange medium for heating the radiator 110. Since the temperature of the heat exchange medium at the outlet of the compressor 101 is relatively high, the temperature of the low-temperature radiator 110 can be rapidly increased, thereby improving heating efficiency and anti-condensation effect.

[0052] Of course, in other embodiments of the present invention, for example, in the cooling mode of the heat exchange system 100, the medium inlet of the temperature control circuit 200 can also be set at the inlet of the indoor heat exchanger 104.

[0053] like Figure 2 and Figure 3 As shown, in another specific embodiment of the present invention, the medium outlet of the temperature control circuit 200 is connected to the inlet of the compressor 101. The heat exchange medium, after heat exchange with the radiator 110, is reintroduced into the compressor 101 for recompression.

[0054] Furthermore, in an optional embodiment of the present invention, the heat exchange system 100 further includes an indoor heat exchanger 104, an outdoor heat exchanger 102, a four-way valve 105, and an expansion valve 103. The outlet of the compressor 101 is connected to the four-way valve 105, and the four-way valve 105 is connected to the indoor heat exchanger 104, the outdoor heat exchanger 102, and the inlet of the compressor 101, respectively. The expansion valve 103 is disposed between the indoor heat exchanger 104 and the outdoor heat exchanger 102. The radiator 110 is disposed between the indoor heat exchanger 104 and the outdoor heat exchanger 102.

[0055] When the heat exchange system 100 is in cooling mode, the outlet of the compressor 101 is connected to the outdoor heat exchanger 102 via a four-way valve 105. The outdoor heat exchanger 102 is connected to the radiator 110 via an expansion valve 103, allowing the low-temperature heat exchange medium to be introduced into the radiator 110 for cooling. The radiator 110 is connected to the indoor heat exchanger 104, which is connected to the inlet of the compressor 101 via a four-way valve 105.

[0056] When the heat exchange system 100 is in heating mode, the outlet of the compressor 101 is connected to the indoor heat exchanger 104 via a four-way valve 105. The indoor heat exchanger 104 is connected to the radiator 110 via an expansion valve 103, allowing the low-temperature heat exchange medium to be introduced into the radiator 110 for cooling. The radiator 110 is connected to the outdoor heat exchanger 102, which is connected to the inlet of the compressor 101 via a four-way valve 105.

[0057] like Figure 1 and Figure 4 As shown, in another optional embodiment of the present invention, the medium outlet of the temperature control circuit 200 is connected between the indoor heat exchanger 104 and the outdoor heat exchanger 102. The heat exchange medium flowing out of the temperature control circuit 200 can be further heat-exchanged through the indoor heat exchanger 104 or the outdoor heat exchanger 102 before entering the compressor 101, thereby improving the working efficiency of the compressor 101.

[0058] For example, in cooling mode, the medium outlet of the temperature control circuit 200 is connected to the inlet of the indoor heat exchanger 104, that is, the medium outlet of the temperature control circuit 200 is connected between the indoor heat exchanger 104 and the radiator 110.

[0059] In heating mode, the medium outlet of the temperature control circuit 200 is connected to the inlet of the outdoor heat exchanger 102, that is, the medium outlet of the temperature control circuit 200 is connected between the outdoor heat exchanger 102 and the radiator 110. A multi-way valve can be used to change the connection position of the medium outlet of the temperature control circuit 200 in different modes.

[0060] In addition, such as Figure 1 As shown, in some optional embodiments of the present invention, the heat exchange system 100 includes a first operating mode in which the medium outlet of the temperature control circuit 200 is connected between the expansion valve 103 and the indoor heat exchanger 104.

[0061] The first working mode is the cooling mode, where the radiator 110 is connected between the expansion valve 103 and the indoor heat exchanger 104, and the medium outlet of the temperature control circuit 200 is connected between the radiator 110 and the indoor heat exchanger 104.

[0062] Specifically, the outlet of compressor 101 is connected to the medium inlet of temperature control circuit 200. After passing through switch valve 201, temperature control circuit 200 is connected to radiator 110. After passing through radiator 110 and flow regulating device 202, medium outlet of temperature control circuit 200 is connected to inlet of indoor heat exchanger 104.

[0063] like Figure 4As shown, in other optional embodiments of the present invention, the heat exchange system 100 further includes a second operating mode in which the medium outlet of the temperature control circuit 200 is connected between the expansion valve 103 and the outdoor heat exchanger 102.

[0064] The second working mode is the heating mode, where the radiator 110 is connected between the expansion valve 103 and the outdoor heat exchanger 102, and the medium outlet of the temperature control circuit 200 is connected between the outdoor heat exchanger 102 and the radiator 110.

[0065] Specifically, the outlet of compressor 101 is connected to the medium inlet of temperature control circuit 200, and after passing through switch valve 201, it enters radiator 110. After passing through radiator 110 and flow regulating device 202, the medium outlet of temperature control circuit 200 is connected to the inlet of outdoor heat exchanger 102.

[0066] like Figure 5 As shown, in one embodiment of the present invention, the radiator 110 includes a first heat exchange pipe 120 and a second heat exchange pipe 130. The first heat exchange pipe 120 is connected to the heat exchange system 100, and the second heat exchange pipe 130 is connected to the temperature control circuit 200.

[0067] Specifically, the first heat exchange pipeline 120 includes a first connection port 121 and a second connection port 122. The first connection port 121 is connected to the indoor heat exchanger 104, and the second connection port 122 is connected to the outdoor heat exchanger 102, providing cooling capacity to the radiator 110 through the heat exchange system 100. The second heat exchange pipeline 130 includes a third connection port 131 and a fourth connection port 132. The third connection port 131 is connected to the medium inlet of the temperature control circuit 200, and the fourth connection port 132 is connected to the medium outlet of the temperature control circuit 200. The first heat exchange pipeline 120 and the second heat exchange pipeline 130 can be arranged in parallel for heat exchange.

[0068] like Figure 6 and Figure 7 As shown, the radiator 110 also includes a body 113. A mounting groove is provided on one side of the body 113 for mounting a first heat exchange pipe 120 and a second heat exchange pipe 130. The first heat exchange pipe 120 and the second heat exchange pipe 130 are mounted on the body 113 by a fixing plate 112. A frequency converter module 210 is fixed on the other side of the body 113.

[0069] The present invention also provides an air conditioner, including a frequency converter module 210 and a radiator anti-condensation device as described in the above embodiment. The radiator 110 is mounted on the frequency converter module 210, and the frequency converter module 210 is used to control the heat exchange system 100. The control unit 112 may be a part of the frequency converter module 210.

[0070] The inverter module 210 is connected to the compressor 101, indoor heat exchanger 104, outdoor heat exchanger 102, four-way valve 105, and expansion valve 103.

[0071] like Figure 8 As shown, the present invention also provides a method for controlling a radiator anti-condensation device, comprising:

[0072] Based on the first temperature value Ts1 of the radiator 110 and the second temperature value Tao of the environment where the radiator 110 is located, the opening of the temperature control circuit 200 is determined.

[0073] Based on the third temperature value Ts2 of the radiator 110 and the preset value Tn, the temperature control circuit 200 is closed.

[0074] For example, the first temperature sensor 203 obtains the current temperature of the radiator 110, i.e., the first temperature value Ts1, and the second temperature sensor 111 obtains the current temperature of the external environment where the radiator 110 is located, i.e., the second temperature value Tao. Of course, when the first temperature value Ts1 is less than the second temperature value Tao, the temperature control circuit 200 is opened, i.e. the switching valve 201 is opened, and the temperature control circuit 200 heats the radiator 110.

[0075] The current temperature value of radiator 110 is obtained again (i.e., the third temperature value Ts2). When the third temperature value Ts2 is greater than the preset value Tn, the temperature control circuit 200 is closed, that is, the switching valve 201 is closed, and heating of radiator 110 is stopped. This ensures that the temperature of radiator 110 is greater than or equal to the external ambient temperature, achieving the anti-condensation effect.

[0076] Furthermore, in another embodiment of the present invention, the radiator anti-condensation device control method further includes:

[0077] The preset value Tn is the sum of the second temperature value Tao and the preset temperature difference value N, where N is greater than 0 degrees.

[0078] In other words, when the current temperature value of the radiator 110, i.e., the third temperature value Ts2, is greater than or equal to the sum of the second temperature value Tao and the preset temperature difference value N, the switch valve 201 is closed. The preset temperature difference value is related to the condensation point temperature of the radiator 110.

[0079] The radiator anti-condensation device provided by the present invention is connected to the heat exchange system 100 through a temperature control circuit 200. The temperature control circuit 200 uses the high-temperature heat exchange medium of the heat exchange system 100 to heat the radiator 110, so that the temperature of the radiator 110 is greater than or equal to the ambient temperature, thereby achieving the anti-condensation effect. The temperature control circuit 200 uses the heat exchange medium of the heat exchange system 100 itself to heat the radiator 110, without an additional heat source, which is simple in structure and reduces costs.

[0080] Furthermore, the air conditioner provided by the present invention also possesses the various advantages described above due to the radiator anti-condensation device described above.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
