Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings.
A kind of enhancing heat exchange type radiation and convection cool-heat-exchanger, mainly by the upper header 1 of radiation and convection cool-heat-exchanger,
The lower header 2 of radiation and convection cool-heat-exchanger, the heat exchanger tube 3 of radiation and convection cool-heat-exchanger, small-sized fans 4, band Lateral supply
Mouthful vertical ventilation pipe 5, Lateral supply mouth 6 is flexible coupling 7 between fan and vertical air hose, and the welding steel 8 of fan is vertically sent
The welding steel 9 of air hose, condensate slot 10, fan inlet steel wire 11 form.In upper header 1, lower header 2 and all radiation
The outer surface of heat convection pipe 3 is covered with ultraphobic aqueous coating.Rectangle is opened on vertical ventilation pipe 5 or round Lateral supply mouth 6 is close to
The outer Lateral supply of heat exchange pipe, to increase heat exchange pipe outer surface flow perturbation, to realize enhanced heat exchange.
Small-sized fans 4 are welded in the fixation for realizing fan in the upper header 1 of radiation and convection cool-heat-exchanger, are vertically sent
With 2 firm welding of the heat exchanger tube 3 of radiation and convection cool-heat-exchanger or lower header at air hose 5 at least two, air supply process is prevented
In vibrate.
With 7 connections that are flexible coupling between small-sized fans 4 and vertical ventilation pipe 5.It is flexible coupling 7 using silica gel glass dimension heat-resisting soft
Material is connected, length is preferably 150mm~300mm, plays the role of vibration isolation and bit shift compensation, and junction should be tight, securely may be used
It leans on, it should there are certain strokes after installing.
Selected small-sized fans 4 are small pipeline wind turbine, point high, medium and low third gear, convenient for according to indoor actual temperature condition tune
Save air quantity of fan and heat transfer intensity；Maximum noise is less than 36dBA, meets the needs of indoor low noise.
By controlling the size of opened Lateral supply mouth 6 on vertical ventilation pipe 5, to realize to comb balanced ventilation.To realize
The area of balanced ventilation, Lateral supply mouth 6 is gradually reduced from top to bottom.
When opened Lateral supply mouth 6 is rectangle on vertical ventilation pipe 5, the vertical height in air port should be not less than horizontal width.
Wind speed general control is in 0.8~4m/s at 5 upside air outlet 6 of vertical ventilation pipe, in the effect for ensureing enhanced heat exchange
Meet requirement of the personnel to blowing feeling other than 1 meter away from equipment simultaneously.
In summer cooling operating mode, when pipeline external surface temperature is less than the dew-point temperature of room air, the flow of condensation
Into in the condensate slot 9 of lower part, and finally drain from condensate discharge pipe, realizes the cooling under wet cooling condition.
When system is when the cold and heat source in summer, winter uses same set of heat pump unit, the cold and heat supply end-equipment in room
A kind of enhancing heat exchange type radiation and convection cool-heat-exchanger may be used.In this case, when needing to room cooling, refrigerant
Fluid carries the cold prepared by heat pump unit and first flows into lower header 2, and then refrigerant flows through vertical arrangement from bottom to top again
Radiation and convection heat exchanger tube 3 during be gradually heated by the sonochemical activity the cooling into room in other words, the refrigerant that temperature increases, density reduces
Fluid is pooled to 1 after upper header, then the water return pipeline by being connected with upper header flows back to heat pump unit, is so recycled, constantly
Cold is provided for room.For the cooling ability of raising equipment, small-sized fans 4 can be opened, blows and flows through vertical ventilation pipe 5, and from
Lateral supply mouth 6 is sent out along 3 outside horizontal direction of radiation and convection heat exchange pipe, to increase the flow perturbation of 3 outer surface of heat exchanger tube, is risen
It is acted on to enhanced heat exchange.Strengthen radiation and convection cool-heat-exchanger when to room cooling, the condensed water that surface generates is by wrapping up
After condensate slot 10 outside lower header 2 is collected, condensate discharge pipe is flowed to along the gradient of condensate trench bottom.
And when needing to rooms, heating agent fluid is flowed into from upper header 1, and lower header 2 flows out, this and cooling
Situation is exactly the opposite, to realize the conversion of flow direction, can be completed by the switching of valve in heat pump unit side.
The gear of small-sized fans can voluntarily be adjusted in user end.For cold season, when indoor refrigeration duty becomes from high to low
When change, accordingly the gear of small-sized fans can be adjusted to from highest it is minimum, until close.Similarly, in warm season, when outdoor gas
It, correspondingly, can be by the gear of small-sized fans from most to a high-profile when temperature changes (i.e. indoor heat load changes from high to low) from low to high
It is extremely minimum, until closing.Cooling/the heat and the variation of indoor cold heat load for making equipment in this way match, to ensure room temperature
It maintains within the scope of human comfort.
