The mobile heat supply module is connected to the heat management module through a first control valve and a second control valve; the first control valve is used to control the heat between the mobile heat supply module and the heat management module, and the second control valve is used to control the cold between the mobile heat supply module and the heat management module; the heat management module is connected to the mobile module, connected to the heat consumption module through a third control valve, and connected to the cold consumption module through a fourth control valve; the third control valve is used to control the heat between the heat management module and the heat consumption module, and the fourth control valve is used to control the cold between the heat management module and the cold consumption module; the heat management module is used to receive the heat provided by the mobile heat supply module, and provide heat to the mobile heat supply module and the heat consumption module, and provide cold to the mobile heat supply module and the cold consumption module.

[0070] See also Figure 2 , is a structural diagram of another mobile heat management system provided in an embodiment of the present application. Figure 2 The structure shown in Figure 1 Based on the system structure shown in FIG, a structure of a mobile heat supply module 11 is further provided. Figure 2 As shown, the mobile heat supply module 11 may include an exhaust module 21 , an air intake module 22 , a ventilation module 23 , and a lubrication module 24 .

[0071] The exhaust module 21 can be connected to the thermal management module 12 via an exhaust control valve 25. The mobile heat supply module 11 can be a mobile generator set that generates electricity by burning fuel. The exhaust module 21 is used to process the exhaust gas generated by the fuel combustion, which can reach a temperature of 400-600 degrees Celsius. The heat carried by the exhaust gas can be transferred to the thermal management module 12 for heat recovery.

[0072] Furthermore, the exhaust control valve 25 is installed on the pipeline connecting the exhaust module 21 and the thermal management module 12 , and can be used to control the amount of heat provided by the exhaust module 21 to the thermal management module 12 .

[0073] Optionally, the amount of heat provided by the exhaust module 21 to the heat management module 12 can be controlled by controlling the opening of the exhaust control valve 25 .

[0074] The air intake module 22 may be connected to the thermal management module 12 via an air intake control valve 26 .

[0075] The air intake module 22 is used to cool the mobile heat supply module 11. For example, when the mobile heat supply module 11 is a mobile generator set, cooling the mobile generator set by the air intake module 22 can improve the power generation efficiency of the mobile generator set.

[0076] Furthermore, the air intake control valve 26 may be installed on a pipeline connecting the air intake module 22 and the thermal management module 12 , and may be used to control the amount of cooling provided by the thermal management module 11 to the air intake module 22 .

[0077] Optionally, the amount of cooling provided by the heat management module 11 to the air intake module 22 may be controlled by controlling the opening of the air intake control valve 26 .

[0078] The ventilation module 23 can be connected to the heat management module via a first ventilation control valve 27 and a second ventilation control valve 28 respectively.

[0079] The ventilation module 23 is used to cool the cabin where the mobile heat supply module 11 is located. For example, when the mobile heat supply module 11 is a gas turbine generator set, the gas turbine generator set generally includes one or two cabins, with the gas turbine and generator in one cabin or separated into two cabins. Both fuel combustion and generator operation can dissipate heat to the cabin, so the cabin needs to be cooled by introducing air through the ventilation module 23 to keep the temperature inside the cabin within a preset range. Furthermore, the air ventilated by the ventilation module 23 can generally reach 70 to 80 degrees Celsius, and this part of the heat can also be recovered by the heat management module 12. The cooling function of the ventilation module 23 on the cabin requires the heat management module 12 to provide heat for the ventilation module 23.

[0080] Furthermore, the first ventilation control valve 27 may be installed in the first ventilation line between the ventilation module 23 and the thermal management module 12 . The first ventilation control valve 27 may be used to control the amount of heat provided by the ventilation module 23 to the thermal management module.

[0081] Furthermore, the second ventilation control valve 28 may be installed in the second ventilation line between the ventilation module 23 and the thermal management module 12 .

[0083] The lubrication module 24 can be used to lubricate and cool rotating components, keeping them within a preset temperature range. The lubricating oil, after absorbing heat, typically reaches temperatures above 70 degrees Celsius, and this heat can be recovered by the thermal management module 12. Furthermore, the lubrication module 24 needs to cool down during operation and also absorbs heat to maintain the fluidity of the lubricating medium. Therefore, the lubrication module 24 can obtain the required heat and cooling through the thermal management module 12.

[0084] Furthermore, the above-mentioned first lubrication control valve 29 can be installed in the first lubrication pipeline between the lubrication module 24 and the thermal management module 12, which can be used to control the heat provided by the lubrication module 24 to the thermal management module 12, and the heat provided by the thermal management module 12 to the lubrication module 24.

[0085] Furthermore, the second lubrication control valve 30 may be installed in the second lubrication pipeline between the lubrication module 24 and the thermal management module 12 , and may be used to control the cooling capacity provided by the thermal management module 12 to the lubrication module 24 .

[0086] The mobile heat management system provided in the embodiment of the present application, the above-mentioned mobile heat supply module may include an exhaust module, an air intake module, a ventilation module, and a lubrication module, wherein the exhaust module, the ventilation module, and the lubrication module can all transfer heat to the heat management module so as to recover the heat of the exhaust module, the ventilation module, and the lubrication module through the heat management module. The heat management module can provide heat to the lubrication module based on the recovered heat, and provide cooling to the air intake module, the ventilation module, and the lubrication module, thereby realizing the recycling of heat in the system.

Figure 3 As shown, the heat consumption module 13 may include an electric driving force module 31 and other heat consumption modules 32 , and the cold consumption module 14 may include a cold consumption module 33 .

[0088] The mobile heat supply module 11 is a mobile generator set.

[0089] The mobile generator set can be connected to the electric driving force module 31 , and the mobile generator set can be used to provide electric energy for the electric driving force module 31 .

[0090] Among them, the above-mentioned mobile generator set can be a gas turbine generator set, which can drive a generator to generate electricity by burning fuel. The above-mentioned electric drive force module 31 can be a driving device for performing external work, such as the electric-driven fracturing equipment in the well site fracturing operation, which can perform external work through the fracturing fluid to complete the fracturing operation. The above-mentioned fracturing fluid needs to be maintained within a preset temperature range. Therefore, in addition to providing electrical energy for driving through the mobile generator set, the electric drive module can also provide heat through the thermal management module 12 to ensure that the fracturing fluid is within the preset temperature range.

[0091] The electric driving force module 31 may be connected to the thermal management module 12 via an electric driving control valve 34 .

[0093] The other heat consumption modules 32 can be connected to the heat management module 12 via other control valves 35 .

[0094] The other heat consumption modules 32 may be other heat consumption modules in the mobile heat management system, which may include anti-icing systems, control room heating, and other heat consumption equipment.

[0095] Furthermore, the other control valve 35 can be installed on the pipeline between the other heat consumption module 32 and the heat management module 12 , and can be used to control the heat provided by the heat management module 12 to the other heat consumption module 32 .

[0096] In an optional solution of the embodiment of the present application, the above-mentioned cold consumption module may include a cold consumption module 33.

[0097] The cooling consumption module 33 can be connected to the heat management module 12 via a cooling control valve 36 .

[0098] Optionally, since the fourth control valve 19 is a control valve between the cooling consumption module 14 and the heat management module 12 , the cooling control valve 36 may not exist, and this embodiment of the present application does not impose any limitation on this.

[0099] The cooling consumption module 33 may be a module for consuming cooling in the system, for example, controlling indoor refrigeration equipment or other cooling equipment in summer.

[0100] Furthermore, the cooling control valve 36 may be installed on the pipeline between the cooling consumption module 33 and the thermal management module 12 , and may be used to control the cooling capacity provided by the thermal management module 12 to the cooling consumption module 33 .

[0101] The mobile heat management system provided in the embodiment of the present application may include an electric drive force module and other heat consumption modules, and the above-mentioned cold consumption module may include a cold consumption module. The heat management module can recover the heat of the mobile heat supply module to provide heat to the electric drive force module and other heat consumption modules that consume heat in the system, and provide heat to the cold consumption module that consumes cold in the system, thereby fully recycling and utilizing the heat generated by the mobile heat supply system.

Figure 4 As shown, the thermal management module 12 may include a heat exchange module 41 , a cooling module 42 , and a control module 43 .

[0103] The heat exchange module 41 may be connected to the first control valve 16 and the second control valve 17 respectively.

[0104] Furthermore, the heat exchange module 41 may be a heat exchanger, which may absorb the received heat through a preset heat exchange medium (such as water).

[0105] The refrigeration module 42 can be connected to the heat exchange module through a refrigeration control valve 44 and connected to the fourth control valve 19 .

[0106] Furthermore, the refrigeration module 42 may include an absorption refrigerator, which may be used to receive the heat exchange medium transmitted by the heat exchanger, cool the heat exchange medium to a cold medium, and provide cold energy to the cold energy consumption module 33 by inputting the cold medium into the cold energy consumption module 33.

[0107] The control module 43 can be connected to the exhaust module 21, the air intake module 22, the ventilation module 23, the lubrication module 24, the electric drive module 31, the other heat consumption module 32, the cold consumption module 33, the heat exchange module 41, and the refrigeration module 42 respectively.

The connection between the control module 43 and the exhaust module 21, the intake module 22, the ventilation module 23, the lubrication module 24, the electric drive module 31, the other heat consumption module 32, the cooling consumption module 33, the heat exchange module 41, and the cooling module 42 can be a Bluetooth connection, a network connection, etc., and it can obtain the temperature value of each module by transmitting signals.

[0110] The above-mentioned control module 43 can be respectively connected to the first control valve 16, the second control valve 17, the third control valve 18, the fourth control valve 19, the exhaust control valve 25, the intake control valve 26, the first ventilation control valve 27, the second ventilation control valve 28, the first lubrication control valve 29, the second lubrication control valve 30, the electric drive control valve 34, other control valves 35, the cooling control valve 36, and the refrigeration control valve 44.

[0111] The control module 43 may be used to determine the target control valve to be adjusted according to the collected temperature value, determine the target opening of the target control valve, and control the opening of the target control valve to be the target opening.

[0112] The mobile heat management system provided in the embodiment of the present application further provides a heat management module which may include a heat exchange module, a refrigeration module, and a control module. The heat exchange module can absorb the heat provided by the mobile heat supply module 11 through a heat exchange medium, and provide heat to other modules through the heat exchange medium. The refrigeration module can cool the heat exchange medium to obtain a cold medium, thereby providing cooling capacity for other modules. The control module can serve as a control center to determine the target control valve and the target opening of the target control valve by collecting the temperature values ​​of each module, thereby realizing the recycling of heat in the system.

[0113] See also Figure 5 , which is a structural diagram of another mobile heat management system provided in an embodiment of the present application. Figure 5 The structure shown in Figure 4 Based on the structure shown in FIG, a structure of a control module 43 is further provided. Figure 5 As shown, the control module 43 may include an information collection unit 51 , a scheduling unit 52 , a control unit 53 , and a cloud server 54 .

[0114] Among them, the above-mentioned information collection unit 51 can be connected to the exhaust module 21, the air intake module 22, the ventilation module 23, the lubrication module 24, the electric driving force module 31, other heat consumption modules 32, the cold consumption module 33, the heat exchange module 41, and the refrigeration module 42 respectively. The information collection unit 51 can be used to collect the temperature values ​​of all the above-mentioned modules.

[0115] The scheduling unit 52 may be connected to the information acquisition unit 51 and the control unit 53. The scheduling unit 52 may be configured to receive the temperature value acquired by the information acquisition unit 51, determine the target control valve and the target opening of the target control valve based on the temperature value, and transmit the target control valve and the target opening to the control unit.

[0116] In one embodiment, when the dispatch unit 52 detects that the temperature of a monitored module has reached a set value, the valve on the corresponding pipeline for that module automatically opens. When the temperature of the module to be monitored reaches the desired set value, the valve automatically closes. Because the working fluid temperature output by the heat exchanger and absorption chiller is constant, the amount of cooling and heating provided by each monitoring module is controlled by adjusting the opening of the control valve on the pipeline.

[0117] Furthermore, control valves (first control valve 16, second control valve 17, third control valve 18, fourth control valve 19, exhaust control valve 25, air intake control valve 26, first ventilation control valve 27, second ventilation control valve 28, first lubrication control valve 29, second lubrication control valve 30, electric drive control valve 34, other control valves 35, cooling capacity control valve 36, and refrigeration control valve 44) are provided at the front end of the heat exchanger and the absorption chiller and on each heat source supply pipeline.

[0118] Furthermore, since the mobile heat management system is mobile, in order to facilitate mobility, the heat exchanger and the refrigerator do not have the function of storing cold / heat. When the scheduling unit 52 obtains that the module needs cold / heat, it automatically opens the corresponding valve, and the amount of cold / heat is achieved by controlling the valve opening.

[0119] Furthermore, the exhaust module 21, ventilation module 23, and lubrication module 24 in the above-mentioned mobile heat supply module 11 can correspond to pre-set priorities. When the scheduling unit 52 determines that the heat currently required to be recovered is small (less than the preset heat threshold), the heat released by the exhaust module 21 can be recovered by opening the first control valve 16 and the exhaust control valve 25. When it is determined that the heat currently required to be recovered is large (greater than or equal to the preset heat threshold), the first control valve 16, the exhaust control valve 25, the ventilation control valve 27, and the lubrication control valve 29 can be opened at the same time to collect the heat released by the exhaust module 21, the ventilation module 23, and the lubrication module 24.

[0120] The control unit 53 can be connected to the first control valve 16, the second control valve 17, the third control valve 18, the fourth control valve 19, the exhaust control valve 25, the intake control valve 26, the first ventilation control valve 27, the second ventilation control valve 28, the first lubrication control valve 29, the second lubrication control valve 30, the electric drive control valve 34, the other control valves 35, the cooling capacity control valve 36, and the refrigeration control valve 44, respectively. The control unit 53 can be used to receive a target control valve and a target opening and control the opening of the target control valve to the target opening. The connection between the control unit 53 and the control valves can be a Bluetooth connection, a network connection, a circuit connection, etc., which is not shown in the figure.

[0121] As an exemplary embodiment, the above-mentioned scheduling unit 52 can make a cold and heat distribution ratio based on the current operating conditions and the temperature value of the required cold / hot module, and convert the distribution ratio into the valve opening at each location. The valve opening instruction is conveyed to the control unit 53, and the control unit 53 can control the control valves at each location to open the valves as required.

[0122] For example, in extremely hot conditions, the air intake module 22 needs to be cooled to increase the power output of the mobile generator set. The ventilation module 23 needs ventilation and cooling, the lubrication module 24 needs cooling, and the control cabin and other cooling consumption modules 33 need air conditioning and cooling. "Cooling" in these cases refers to lowering the temperature to a pre-set threshold. Based on this, the information collection unit 51 collects the above temperature values ​​and heat exchange medium flow rates and transmits this information to the scheduling unit 52.

[0123] Afterwards, the dispatch unit 52 performs matching calculations and outputs valve opening information to the control unit 53. The control unit 53 then issues control instructions to each control valve to achieve cooling capacity generation and distribution. Specifically, the first control valve 16, the exhaust control valve 25, the first ventilation control valve 27, and the first lubrication control valve 29 are opened. Of these control valves, the first control valve 16 and the exhaust control valve 25 are typically opened first. This prioritizes heat from the exhaust module 21 for the absorption chiller (the exhaust module 21 has a higher temperature and a larger flow rate, making it the primary source of heat). The absorption chiller then operates, outputting a pre-set cooling medium.

[0124] Afterwards, the control valves set in the corresponding modules control the transmission of a specific amount of cooling energy to the corresponding modules according to the control instructions issued by the control unit 53. At this time, other valves are closed and the heat exchanger does not work.

[0125] Continuing with the assumption that, in extremely cold conditions, the electric drive module 31 needs to be protected from icing, the heat consumption module 32 requires heat for de-icing, the lubrication module 24 requires heat to maintain good fluidity, and the control cabin requires air conditioning and heating. The temperature values ​​of these modules, along with the current heat source temperature and flow, are collected by the information acquisition unit 51 and transmitted to the scheduling unit 52. After matching calculations, the scheduling unit 52 outputs control valve opening information and transmits it to the control unit 53. The control unit 53 issues control instructions to each control valve to achieve heat conversion and distribution.

[0126] The specific process is to open the first control valve 16, the exhaust control valve 25, the first ventilation control valve 27, and the first lubrication control valve 29. Among the above control valves, the first control valve 16 and the exhaust control valve 25 are usually opened first, that is, the heat of the exhaust module 21 is used first to provide the absorption refrigerator (the exhaust module 21 has a higher temperature and a larger flow rate and is the main source of heat). After the heat exchanger works, it outputs a relatively high heat exchange medium set in advance.

[0127] Based on this, a specific amount of heat is transferred to the corresponding module by controlling the control valves provided in the corresponding module according to the control instructions issued by the control unit 53. At this time, other valves are closed and the absorption chiller does not work.

[0128] Continuing with the assumption that the ambient temperature is between extremely high and extremely low, the scheduling unit 52 allocates the cooling and heating resources proportionally based on actual on-site needs. The allocation principle prioritizes ensuring the normal operation of the fracturing operation (i.e., the electric drive module 31 ), such as the temperature of the fracturing fluid (the temperature of the electric drive module 31 ), the temperature of the gas turbine generator lubricating oil (the temperature of the lubrication module 24 ), and the temperature of the gas turbine nacelle ventilation (the temperature of the ventilation module 23 ).

[0129] In one embodiment, in a mobile thermal management system, the flow of heat and cold can be as follows: Figure 6 As shown, see Figure 6 , is a schematic diagram of the flow of heat and cold provided in an embodiment of the present application. Figure 6 As shown, the exhaust module 21, the ventilation module 23, and the lubrication module 24 can provide heat for the heat exchanger 61, and the heat exchanger 61 can provide heat for the ventilation module, the lubrication module, the electric drive module 31, and other heat consumption modules 32. The heat exchanger 61 can also provide heat exchange medium for the absorption refrigerator 62. The absorption refrigerator 62 can cool the heat exchange medium into a cold medium and output the cold medium to the air intake module 22, the ventilation module 23, the lubrication module 24, and the cold consumption module 33 to provide cold energy for the air intake module 22, the ventilation module 23, the lubrication module 24, and the cold consumption module 33.

[0130] Furthermore, the cloud server 54 can be connected to the information collection unit 51 and the control unit 53 respectively. The cloud server can be used to obtain the temperature value collected by the information collection unit 51 and the control instruction generated by the control unit 53. The control instruction is used to control the opening of the target control valve to the target opening.

[0131] The mobile thermal management system provided in the embodiment of the present application further provides a control module that may include an information collection unit, a scheduling unit, a control unit, and a cloud server. The information collection unit can be used to collect the temperature values ​​of each module and send the temperature values ​​of each module to the scheduling unit. The scheduling unit determines the target module in each module that needs to transfer heat or cold, as well as the target opening of the target control valve corresponding to the target module, and sends the target control valve and the target opening to the control unit. The control unit generates corresponding control instructions based on the target control valve and the target opening, and sends the control instructions to the corresponding target module to control the target control valve corresponding to the target module to open according to the target opening. Through the above-mentioned information collection unit, scheduling unit, and control unit, information is collected and analyzed for each module in the system, and the corresponding control valve is controlled, so that the heat in the mobile thermal management system can be recovered and reused more accurately.
