Embodiment
Below in conjunction with Fig. 1, embodiment of the present utility model is elaborated.The example below illustrated is only illustration, content of the present utility model do not get rid of following do not express various distortion, technology be suitable for.That is, the utility model can carry out various distortion and implement in the scope not exceeding its aim.
First embodiment
Fig. 1 is the schematic diagram with the TCD detecting device of cooling device of diagram according to the first embodiment.As shown in Figure 1, first embodiment of the present utility model provides a kind of TCD detecting device with quick cooling function, and it comprises: outer cover 4, because TCD pool part temperature is more stable better, outer cover 4 can isolate the interference of outer bound pair pond temperature effectively, makes interior space temperature more stable; TCD pond body assembly 3, be configured to be covered conjunction by outer cover 4, this TCD pond body assembly 3 is cores of TCD detecting device, is the parts detecting chromatographic signal; Heat conducting sleeve 2, be configured to circumference and surround TCD pond body assembly 3, and form an entirety with TCD pond body assembly 3, when needs heating TCD pond, can even heat be conducted on the body of TCD pond, TCD pond body is heated more even, when needs fast cooling, needs equally by heat conducting sleeve to take away the heat on the body of TCD pond.This TCD detecting device comprises further: cooling tube 1, is configured to be coiled in heat conducting sleeve 2 outside surface; Refrigerant generating means 10, the delivery outlet of this refrigerant generating means 10 is connected with the import of cooling tube 1.TCD detecting device also comprises well heater 5, temperature sensor 6 and thermal conductance block 7.Well heater 5 is heaters, by applying voltage, calandria is generated heat, thus makes TCD pond temperature increase by heat transfer.By temperature sensor 6 feedback signal, thus realize the control of accurate temperature.The heat conduction that calandria produces by thermal conductance block 7 is to TCD pond body assembly.The refrigerant generating means of this TCD detecting device is the pump exporting gas or liquid, such as, by the device of the air in the external world by Output pressure, and the air compressor machine or small air pump etc. of such as delivery air.The import of the described cooling tube of this TCD detecting device and outlet are passed through described outer cover and are exposed from described outer cover.
According to the TCD detecting device with cooling device of the utility model first embodiment in use as a detection part of gas chromatograph, for detections such as gas concentrations, the control circuit of time gas chromatography instrument is used to be detected the internal temperature of TCD detecting device by temperature sensor 6, heated up by TCD detecting device internal heater 5 pairs of TCD detecting devices, realize detection at high temperature.When needing cooling after detection terminates, well heater 5 just quits work.Under normal circumstances, because TCD pond body is combined in an almost airtight space, so cooling slowly.And according to the TCD detecting device with cooling device of the utility model first embodiment, have cooling tube 1, such as copper pipe, glass tube, leather hose etc. in the coiling of heat conducting sleeve 2 outside surface, but the example of cooling tube 1 is not limited thereto, and can be resistance to high high temperature, any pipe of such as more than 400 DEG C.Now, refrigerant generating means 10 is started working and is exported refrigerant, and flow in cooling tube 1 refrigerant fast that exported by refrigerant generating means 10, thus taken away by heat rapidly.Especially, the refrigerant exported by refrigerant generating means 10 is normal temperature or lower than the gas of normal temperature or liquid, such as, can be gas or the liquid of less than 35 DEG C, be more preferably, the gas of less than 15 DEG C or liquid, but the temperature of gas or liquid is not limited to concrete numerical value described above, and the lower gas of temperature or liquid, cooling effect is better.Again, such as, the refrigerant exported by refrigerant generating means 10 is the air of normal temperature.For example, the flow velocity of the refrigerant exported by refrigerant generating means 10 that to flow fast in cooling tube 1 can control at about 5L/min, can realize comparatively significantly cooling-down effect.And the flow velocity of this refrigerant is not limited thereto, such as, can be the arbitrary value higher than 5L/min, and the flow velocity of refrigerant is faster, cooling effect be better.
Thus, when needing cooling after detection terminates, by cooling fast according to the cooling device work of the utility model first embodiment, meet the requirement that TCD detecting device cools fast, simultaneously, also solve the too high and technical matters damaged of semiconductor chilling plate easy Yin Wendu in TCD sensors work process disclosed in patent documentation 1, and this installation cost is very low, without the need to semiconductor chilling plate as disclosed in Patent Document 1 in TCD detecting device the required main frame temperature-controlled portion by gas chromatograph to the Special controlling of the control of thermal conductivity detector (TCD) and cooling piece etc., be easy to user operation.
Second embodiment
Comprise joint transition components 8 and flexible pipe 9 further according to the TCD detecting device of the second embodiment of the present utility model, the delivery outlet of refrigerant generating means 10 is connected with the import of flexible pipe 9 with cooling tube 1 via joint transition components 8.Joint transition components 8 is the X-overs be connected with flexible pipe 9 by cooling tube 1.Flexible pipe 9 is the supporting pipes being connected to refrigerant generating means 10.By configuration joint transition components 8 and flexible pipe 9, make more to be easy to control the operation to refrigerant generating means 10, such as, make it start working or quit work.
Consider above-mentioned instruction, much other distortion and change are possible.Therefore be understandable that, within the scope of the appended claims, can to realize content disclosed in the utility model except specifically described mode herein.For example, in the scope of the disclosure with additional claim, the parts of different examples and illustrative embodiment and/or characteristic can be combined with each other and/or phase trans-substitution.
