Fig. 5 is a flowchart of the method for regulating the internal temperature of a sealed outdoor cabinet according to the present application. As shown in fig. 5, after the system is started, initialization is performed first, and then it is determined whether the heat exchange condition is satisfied. The electronic device needs to operate within its suitable temperature range, whereby the lowest value of this temperature range is the lower temperature threshold limit TLThe highest value of the temperature range is the upper limit T of the temperature thresholdH. The system heat exchange determination conditions are as follows:
1) ambient temperature inside the cabinet (temperature of the heat exchanger 21 inside the cabinet)<TLAnd the ambient temperature in the cabinet<The temperature of any one of the external cabinet heat exchangers 24, 25, 26 outside the cabinet (the external environment temperature outside the cabinet), the interior of the cabinet absorbing heat from outside the cabinet;
2) ambient temperature in the cabinet>THAnd the ambient temperature in the cabinet>The temperature of any one of the external heat exchangers 24, 25 and 26 dissipates heat from the inside of the cabinet to the outside of the cabinet;
3)TL<ambient temperature in the cabinet<THWhen the temperature in the cabinet is in a range suitable for the electronic equipment to work, active heat exchange with the outside is not needed in the cabinet, and the circulating pump 22 can stop working;
4) in winter, when the ambient temperature in the cabinet<TLTime, the ambient temperature in the cabinetThe temperature of the heat exchangers 24, 25 and 26 outside the cabinet is higher than that of the heat exchangers outside the cabinet, which shows that the temperature in the cabinet is higher than the outside temperature, and the heat exchange with the outside is not needed at the moment;
5) in summer, the ambient temperature in the cabinet>THTime, the ambient temperature in the cabinet<The heat exchange between all the radiators and the outside only can make the temperature in the cabinet higher, so the heat exchange is stopped at the moment.
When the heat exchange condition is met, the system is started, and the heat exchange direction is judged, wherein the specific method comprises the following steps:
1) the conditions of "1)" and "2)" are known from the above heat exchange determination conditions, and the heat exchange system needs to be started, and the communication between the in-cabinet heat exchanger 21 and the first out-cabinet heat exchanger 24, the second out-cabinet heat exchanger 25 and the third out-cabinet heat exchanger 26 is controlled through the first reversing valve 23 and the second reversing valve 27, that is, heat is absorbed from the outside or is radiated to the outside;
2) due to season change, the environmental temperature is lower in winter and higher in summer, and meanwhile, the temperature of the surface of the cabinet exposed to the sun is high, and the temperature of the cabinet exposed to the sun is lower. The temperature sensor 28 at the outlet of each heat exchange device can detect the real-time temperature of each heat exchange device, so that the temperature of the in-cabinet heat exchanger 21 and the temperatures of the outlet ends of the first out-cabinet heat exchanger 24, the second out-cabinet heat exchanger 25 and the third out-cabinet heat exchanger 26 can be used for judging which out- cabinet heat exchanger 24, 25 and 26 needs to exchange heat;

For example, in winter and daytime, heat needs to be taken from the outside, and the heat exchange is automatically switched to the sunny side;
4) when heat dissipation to the outside is required, it can be determined which of the three external heat exchangers 24, 25, 26 has the lowest temperature, and the direction of the switching valve is communicated to which of the external heat exchangers 24, 25, 26. For example, in summer, the sunshine is abundant in daytime, heat dissipation to the outside is needed, and heat exchange with the sun-back surface is automatically selected.
5) When the in-cabinet heat exchanger 21 needs to dissipate heat and there are a plurality of out- cabinet heat exchangers 24, 25, 26 with a temperature lower than the temperature of the in-cabinet heat exchanger 21, the system preferentially drives the in-cabinet heat exchanger 21 to exchange heat with the out- cabinet heat exchanger 24, 25, 26 with the lowest temperature.
6) When the in-cabinet heat exchanger 21 needs to absorb heat, and there are a plurality of out- cabinet heat exchangers 24, 25, 26 with a temperature higher than that of the in-cabinet heat exchanger 21, the system preferentially drives the in-cabinet heat exchanger 21 to exchange heat with the out- cabinet heat exchangers 24, 25, 26 with the highest temperature.
From above, when the temperature sensor 28 detects the temperature of the in-cabinet heat exchanger 21<TLWhen the temperature sensor 28 detects that the temperature of any one of the outdoor heat exchangers 24, 25, 26 is higher than the temperature of the indoor heat exchanger 21, the first reversing valve 23 and the second reversing valve 27 communicate the indoor heat exchanger 21 with any one of the outdoor heat exchangers 24, 25, 26 higher than the temperature of the indoor heat exchanger 21, and the circulation pump drives the heat exchange medium to circulate between the indoor heat exchanger 21 and any one of the outdoor heat exchangers 24, 25, 26 higher than the temperature of the indoor heat exchanger 21. When the temperature sensor 28 detects the temperature of the in-cabinet heat exchanger 21>THWhen the temperature sensor 28 detects that the temperature of any one of the outdoor heat exchangers 24, 25, 26 is lower than the temperature of the indoor heat exchanger 21, the first reversing valve 23 and the second reversing valve 27 communicate the indoor heat exchanger 21 with any one of the outdoor heat exchangers 24, 25, 26 having a temperature higher than the temperature of the indoor heat exchanger 21, and the circulation pump drives the heat exchange medium to circulate between the indoor heat exchanger 21 and any one of the outdoor heat exchangers 24, 25, 26 having a temperature higher than the temperature of the indoor heat exchanger 21. Thus, the heat exchange between the in-cabinet heat exchanger 21 and the appropriate out- cabinet heat exchangers 24, 25, and 26 can be realized, and the temperature in the cabinet can be adjusted.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
