The specific embodiment
Below by embodiment, and 1-6b by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.In description, same or analogous drawing reference numeral is indicated same or analogous parts.Followingly with reference to accompanying drawing, the explanation of embodiment of the present invention is intended to present general inventive concept of the present invention to make an explanation, and does not should be understood to a kind of restriction of the present invention.
In the fields such as HVAC, air conditioning for automobiles, refrigeration and transportation, conventionally on heat exchanger devices such as evaporimeter or condenser or product, temperature-sensitive bag is installed and is measured in real time temperature.
Operation principle and the effect of temperature-sensitive bag will be illustrated below.
The operation principle of temperature-sensitive bag, is that to utilize the temperature variant rule of the various physical propertys of material be usable output signal temperature transition, pilot controller work.Temperature-sensitive package gripper is in its erecting device, and temperature-sensitive bag senses temperature in heat exchanger tube by main part or the insertion section heat transfer of this erecting device, is converted into exportable signal, is transferred to controller.
The effect of temperature-sensitive bag is mainly manifested in following several respects (general conventional control flow):
1, under refrigeration mode, compressor is protected.
Control the open and close operation of compressor and outer blower fan.
2, under heating mode, the function that has anti-cold wind, blows waste heat and controlled wind speed.
According to the temperature of test, control inner blower and open or close and wind speed; Anti-blowing a cold wind over and waste heat.
3,, under heating mode, there is high temperature protection function.
During heating operation, if the temperature of measuring is higher, stop outer blower fan work; If this temperature continues to raise again, stop compressor operating.
4,, under heating mode, control the unlatching of auxiliary electrical heater.
When the temperature of measuring is lower, compressor start, the running of outer blower fan, reversal valve obtain electric, indoor fan and open, and auxiliary electrical heater is opened.When this temperature reaches certain value, auxiliary electrical heater is closed.
Find out thus, temperature-sensitive wraps in whole control system and plays very large effect, is the vitals in air-conditioner control system.If its installation and placement location are bad, even come off, cause the surface temperature measurement of the devices such as evaporimeter or condenser inaccurate, directly have influence on the work of air-conditioner control system.
Temperature-sensitive bag mounting means based on using in current industry is not all fine, quick not and firm, so be necessary this device to be optimized design.
Referring to Fig. 1 and 2, it shows according to heat exchanger 100 of the present invention.Particularly, temperature-sensitive bag erecting device 50 of the present invention is fixed to described heat exchanger 100 by temperature-sensitive bag 60.
Particularly, as can be seen from Figure 1, heat exchanger 100 comprises inlet header 10 and outlet header 20.Between inlet header 10 and outlet header 20, be provided with some such as the heat exchanger tube 30 of flat tube.In addition, can also between two adjacent heat exchanger tubes 30, be provided with a plurality of fins 40.Temperature-sensitive bag erecting device 50 is installed on described heat exchanger tube 30 and/or fin 40.For example by slice, weld welded and installed on described heat exchanger tube 30 and/or fin 40 particularly, and this temperature-sensitive bag erecting device 50 also comprises the temperature-sensitive bag 60 being installed on wherein.
In view of at this, main improvement is temperature-sensitive bag 60 to be installed on mode and the structure on heat exchanger 100, therefore heat exchanger 100 described herein is only for example of illustration purpose.Therefore, at this, no longer describe structure and the principle of heat exchanger 100 in detail.Those skilled in the art are known, as long as situation allows, temperature-sensitive bag erecting device 50 of the present invention can be applied to the heat exchanger of any type, or even the following heat exchanger of designing.
