[embodiment]
As shown in Figure 2; The verifying attachment of a kind of two middle air cooling utmost point radio frequency acanthin amounts that present embodiment provides; It comprises a control device 1, a display 2, a heating component, one first ebullator 3 and a refrigerating plant 4, and this heating component comprises that one second ebullator 5, adds a hot water storgae 6 and a temperature sensor 7; Wherein, This control device 1 and this display 2, first ebullator 3, refrigerating plant 4, second ebullator 5, add hot water storgae 6 and temperature sensor 7 and be and be electrically connected; This first ebullator 3 and this refrigerating plant 4 are connected through pipeline, and this second ebullator 5 adds hot water storgae 6 with this and is connected through pipeline.In addition, this verifying attachment also comprises a casing, and control device 1, first ebullator 3, second ebullator 5 and add hot water storgae 6 and be positioned at casing, and refrigerating plant 7 is positioned at outside the casing.Move therapy apparatus for ease, pulley also is housed at bottom of shell.
In the present embodiment, first ebullator 3 is a peristaltic pump, and the peristaltic pump flow is 50-100ml/min; Second ebullator 5 is the magnetic force water circulating pump, and magnetic force water circulating pump flow is 201/min, the magnetic force water circulating pump with add hot water barrel's pipeline closure forming a circulation waterway, its uniform rotation can make the hot water that adds among the hot water barrel constantly obtain circulation; Refrigerating plant 4 is an exact constant temperature tank.
The method of using above-mentioned verifying attachment that air cooling utmost point radio frequency pin in two is tested is:
1) water inlet with two middle air cooling utmost point radio frequency pins 100 to be measured is connected to form a circulation waterway with this first ebullator 3, this refrigerating plant 4 through pipeline respectively with water delivering orifice; The thermopair of two middle air cooling utmost point radio frequency pins to be measured is connected with control device 1 to form a temperature measurement circuit;
2) coolant-temperature gage of refrigerating plant 4 is set to 7 ℃ then, circulates this chilled water in the air cooling utmost point radio frequency pin to be measured in two;
3) the syringe needle insertion with two middle air cooling utmost point radio frequency pins to be measured adds hot water storgae; The coolant-temperature gage that will add hot water storgae successively is adjusted into 60 ℃ of temperature spots, 70 ℃, 80 ℃, 85 ℃; Let two middle air cooling utmost point radio frequency pin to be measured stop respectively about 10 minutes at each temperature spot, the temperature value that control device is surveyed thermopair shows on display;
4) check data and the normal data of two middle air cooling utmost point radio frequency pins again that each is to be measured compare, and judge the quality of two middle air cooling utmost point radio frequency pins that this is to be measured; Generally speaking, if do not meet at the check data and the normal data of any temperature spot, then think this to be measured two in air cooling utmost point radio frequency pins off quality; Multidata does not meet more, and the quality of this radio frequency pin is poor more.
Above-mentioned normal data be qualified two in air cooling utmost point radio frequency pin according to the method described above first three step operate gained: the thermopair measured temperature is between 56 ℃-58 ℃ in the time of 60 ℃; The thermopair measured temperature is between 64 ℃-67 ℃ in the time of 70 ℃; The thermopair measured temperature is that the thermopair measured temperature is between 79-80 ℃ in the time of 85 ℃ between 75 ℃-77 ℃ in the time of 80 ℃.
In the above-mentioned normal data, it is because the thermostatted water between two middle air cooling utmost point radio frequency pin outsides and the inside exists temperature difference just to have hot transport phenomenon generation that the thermopair measured temperature can hang down than the temperature of needle point external heat medium.
Cause the check data and the normal data of two middle air cooling utmost point radio frequency pins to be measured not to meet, a common reason is that thermopair is not inserted in the syringe needle.Specifically be that case hot galvanic couple measured temperature is with y=k
1X
1+ K
2X
2Expression, k
1Be the coefficient of hot water influence, X
1Be the hot water temperature, K
2Be cold water influence coefficient, X
2Be cold water temperature; If the thermopair in the radio frequency pin is inserted under the situation of needle point endoporus, when hot water temperature and cold water temperature one timing, the thermopair temperature detected can be stabilized in some fixed values; If thermopair fails to be inserted into the needle point place, this can make the thermopair measured temperature coefficient k of different insertion depths
1, K
2Needle point place thermopair measured temperature coefficient is inequality with being inserted into; The final data of measuring according to the above-mentioned method of inspection are littler than normal data usually.
The utility model is not limited to the foregoing description, and for example, verifying attachment can be provided with four groups of heating components, and two middle air cooling utmost point radio frequency pins add the test of carrying out a temperature spot in the hot water storgae at each; More temperature spot can be set tests; Based on simple replacement the foregoing description, that do not make creative work, should belong to the scope that the utility model discloses.
