The present invention proposes a load adjusting device 100, the load adjusting device 100 being connected to a cooler 200 for detecting the performance of the cooler 200.
Referring to fig. 1, in the embodiment of the present invention, the load adjusting device 100 includes a heating assembly 10 and an adjusting unit 20, wherein the heating assembly 10 includes a heater 11 and a circulation line 12, the circulation line 12 connects the heater 11 and a cooler 200, a liquid discharged from the cooler 200 enters the heating assembly 10 through the circulation line 12 to be heated, and a liquid heated by the heating assembly 10 enters the cooler 200 through the circulation line 12;
The regulating unit 20 comprises a controller 21 and a detector 22, the detector 22 is arranged on the circulation pipeline 12 and used for detecting liquid in the circulation pipeline 12, and the controller 21 is connected with the detector 22 and the heater 11;

In the present invention, the load adjusting device 100 includes a heating unit 10 for heating a liquid and an adjusting unit 20 electrically connected to the heating unit 10, and when the load adjusting device 100 is used to detect the cooler 200, the heating unit 10 and the cooler 200 are connected by a circulation line 12, so that the liquid in the cooler 200 can circulate in the cooler 200 and the heater 11. The heater 11 heats the liquid discharged from the cooler 200 to raise the temperature of the liquid, and then the temperature of the liquid is lowered by the cooler 200, so that the cooling performance of the cooler 200 can be detected.
When the model of the cooler 200 is different, the heater 11 required at the time of detecting the cooler 200 is different. The adjusting unit 20 in the technical solution of the present invention can adjust the heater 11 according to preset information, when detecting different coolers 200, the preset information is different, and can adjust the heater 11 to output with different heating powers or adjust the heater 11 to heat with different durations, so that the load adjusting device 100 does not need to replace the heater 11 when testing different types of coolers 200, and the load adjusting device 100 has strong versatility.
Further, the adjusting unit 20 in the technical solution of the present invention further includes a detector 22, which can detect the liquid in the circulation line 12 and further adjust the heater 11 according to the detection result, so that the load adjusting device 100 is safer and more reliable to use.
The above-mentioned preset information may be an output power value of the heater 11 corresponding to the model of the cooler 200. The above-described preset information may also be a temperature increase value of the liquid heated by the heater 11 corresponding to the model of the cooler 200.
In the above embodiment, the detector 22 may include a temperature sensing component 221 disposed in the circulation line 12, the temperature sensing component 221 detects a temperature difference between the upstream and downstream of the heater 11, and the controller 21 is connected to the temperature sensing component 221, and the preset information includes a preset temperature;
The controller 21 compares the temperature difference upstream and downstream of the heater 11 with a preset temperature, and adjusts the heater 11 according to the comparison result.
The preset temperature is an actual elevated temperature value of the liquid flowing into the cooler 200 required during the detection of the cooler 200. The temperature difference detected by the temperature sensing assembly 221 between the upstream and downstream of the heater 11 is the actual increase in the temperature of the liquid during the heating of the liquid by the heater 11. According to the detected temperature difference between the upstream and downstream of the heater 11 and the preset temperature, it can be determined whether the heating condition of the heater 11 on the liquid meets the actual requirement.
In the above embodiment, the circulation pipeline 12 includes the first pipeline 121 and the second pipeline 122, the first pipeline 121 connects the liquid outlet of the cooler 200 and the liquid inlet of the heater 11, and the second pipeline 122 connects the liquid outlet of the heater 11 and the liquid inlet of the cooler 200;
the temperature sensing assembly 221 includes a first temperature sensor 2211 and a second temperature sensor 2212, the first temperature sensor 2211 is disposed in the first pipeline 121 to detect the temperature of the liquid in the first pipeline 121, and the second temperature sensor 2212 is disposed in the second pipeline 122 to detect the temperature of the liquid in the second pipeline 122; the controller 21 connects the first temperature sensor 2211 and the second temperature sensor 2212;
the controller 21 compares the difference between the first temperature sensor 2211 and the second temperature sensor 2212 with a preset temperature, and adjusts the heater 11 according to the comparison result.
The first temperature sensor 2211 can detect the temperature of the liquid before the heater 11 heats, the second temperature sensor 2212 can detect the temperature of the liquid after the heater 11 heats, and the difference between the first temperature sensor 2211 and the second temperature sensor 2212 is the actual increase of the temperature of the liquid during the heating process of the liquid by the heater 11.
In the above embodiment, the controller 21 compares the difference between the first temperature sensor 2211 and the second temperature sensor 2212 with the preset temperature, and adjusting the heater 11 according to the comparison result includes:
When the difference between the first temperature sensor 2211 and the second temperature sensor 2212 is greater than the preset temperature, the controller 21 may control the heating power of the heater 11 to be reduced;
when the difference between the first temperature sensor 2211 and the second temperature sensor 2212 is less than the preset temperature, the controller 21 may control the heating power of the heater 11 to be increased.
When the difference between the first temperature sensor 2211 and the second temperature sensor 2212 is greater than the preset temperature, which indicates that the actual output power of the heater 11 is higher, the output power of the heater 11 can be controlled to be reduced, so that the actual heating condition of the heater 11 on the liquid meets the requirement.
When the difference between the first temperature sensor 2211 and the second temperature sensor 2212 is smaller than the preset temperature, which indicates that the actual output power of the heater 11 is low, the output power of the heater 11 can be controlled to increase, so that the actual heating condition of the heater 11 on the liquid meets the requirement. Thus, the load power provided by the load adjusting device 100 to the cooler 200 is accurate, and the detection effect of the cooler 200 is more accurate.
In the above embodiment, the first temperature sensor 2211 is disposed adjacent to the liquid outlet of the cooler 200, and the second temperature sensor 2212 is disposed adjacent to the liquid inlet of the cooler 200.
The second temperature sensor 2212 can more accurately detect the temperature of the liquid flowing into the cooler 200, and the first temperature sensor 2211 can more accurately detect the temperature of the liquid cooled by the cooler. When the circulation pipeline 12 is overlong, the heat loss of the liquid in the flowing process in the circulation pipeline 12 is prevented from influencing the detection result, so that the load power is accurate, and the detection effect of the cooler 200 is more accurate.
In the above embodiment, the controller 21 may also determine whether the value of the second temperature sensor 2212 is greater than a preset limit temperature, and when the value of the second temperature sensor 2212 is greater than the preset limit temperature, the controller 21 controls the heater 11 to be turned off.
This step can prevent a safety accident caused by an excessively high heating temperature when the heater 11 is abnormal, and ensure the safety and reliability of the load adjusting device 100 during use.
In the above embodiment, the detector 22 may include a flow sensor 222 provided in the circulation line 12, the flow sensor 222 detecting the flow rate of the liquid flowing out of the cooler 200, and the controller 21 connected to the flow sensor 222 and adjusting the heater 11 according to the flow rate of the liquid of the cooler 200 and preset information.
The heater 11 may control the heating power according to the flow rate of the liquid flowing out of the cooler 200. Specifically, when the circulation line 12 includes the first line 121 and the second line 122, the flow sensor 222 may be disposed in the first line 121 to detect the flow rate of the liquid flowing out of the cooler 200. When a large flow rate of the liquid is detected, the heating power of the heater 11 can be controlled to be increased; when a small flow rate of the liquid is detected, the heating power of the heater 11 can be controlled to be reduced to save heating time.
In the above embodiment, the controller 21 adjusting the heating power of the heater 11 according to the flow rate of the liquid flowing out of the cooler 200 and the preset information includes:
when the flow rate of the liquid flowing out of the cooler 200 is smaller than the flow rate preset flow rate, the heater 11 is controlled to be turned off.
The preset flow is the flow value of the liquid in the circulation line 12 with the cooler 200 turned off. When the flow rate of the liquid in the circulation line 12 is smaller than the preset flow rate, the heater 11 is controlled to be turned off to prevent the heater 11 from being damaged when the cooler 200 is judged to be in the shutdown state.
The detector 22 may include a temperature sensing assembly 221 provided to the circulation line 12, the temperature sensing assembly 221 detecting a temperature difference upstream and downstream of the heater 11;
the detector 22 may also include a flow sensor 222 disposed in the circulation line 12, the flow sensor 222 detecting the flow of liquid out of the cooler 200;
The controller 21 is connected with the temperature sensing assembly 221 and the flow sensor 222, and obtains load power according to the density of the liquid, the specific heat of the liquid, the flow rate of the liquid and the temperature difference between the upstream and downstream of the heater 11;
The controller 21 adjusts the heating power of the heater 11 according to the load power.
After the controller 21 is powered on, the values of the flow sensor 222 and the temperature sensing component 221 can be collected in real time, and the load power of the current load adjusting device 100 can be calculated.
The load power of the load adjusting device 100 can be calculated by the following formula: p=ρ×c×v×Δt, (P is load power, ρ is liquid density, C is liquid specific heat, v is liquid flow rate, Δt is temperature difference). Wherein the liquid density and the specific heat of the liquid are known parameters. The controller 21 adjusts the heater 11 according to the load power, specifically can adjust the power of the heater 11 and/or the heating duration of the heater 11, so that the heater 11 can accurately heat the liquid, the heating efficiency is high, the load power is accurate, and the detection effect of the cooler 200 is more accurate.
Specifically, the controller 21 may adjust the operation duty ratio of the heater 11 according to the load power and the preset power of the heater 11. The duty cycle is the proportion of the actual heating time of the heater 11 in the working cycle, so that the real-time heating load is equal to the preset heating load.
The load adjusting device 100 of the technical scheme of the invention can be directly connected between the liquid inlet pipe and the liquid outlet pipe of cooling, does not need to be arranged in the liquid tank of the cooler 200, has no requirement on the size of the liquid tank of the cooler 200, and has strong universality.
In the above embodiment, the liquid inlet valve and/or the liquid outlet valve may be provided in the circulation line 12, and the operation of the load adjuster 100 may be controlled by controlling the liquid inlet valve and/or the liquid outlet valve. Specifically, the first pipe 121 may connect the liquid outlet of the cooler 200 and the liquid inlet of the heater 11, and the second pipe 122 may connect the liquid outlet of the heater 11 and the liquid inlet of the cooler 200. A liquid inlet valve may be provided between the liquid outlet pipe of the cooler 200 and the first pipe 121, a liquid outlet valve may be provided between the liquid inlet pipe of the cooler 200 and the second pipe 122, and whether the load adjuster 100 operates may be controlled by controlling the liquid inlet valve and the liquid outlet valve.
