Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
One kind 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, the welding steel 8 of fan, vertically send between fan and vertical air hose
The welding steel 9 of air hose, condensate groove 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 circular Lateral supply mouth 6 is close to
The outer Lateral supply of heat exchange pipe, to increase heat exchange pipe outer surface flow perturbation, so as to fulfill enhanced heat exchange.
Small-sized fans 4 are welded in the fixation that fan is realized in the upper header 1 of radiation and convection cool-heat-exchanger, are vertically sent
With 2 firm welding of heat exchanger tube 3 or lower header of radiation and convection cool-heat-exchanger 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, its junction should be tight, firmly may be used
Lean on, certain stroke should be left after installing.
Selected small-sized fans 4 are small pipeline wind turbine, point high, medium and low third gear, easy to 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.
The size of Lateral supply mouth 6 is opened on vertical ventilation pipe 5 by controlling, to realize to comb balanced ventilation.To realize
Balanced ventilation, the area of Lateral supply mouth 6 are gradually reduced from top to bottom.
When Lateral supply mouth 6 is opened on vertical ventilation pipe 5 is rectangle, the vertical height in air port should be not less than horizontal width.
Wind speed general control is ensureing the effect of enhanced heat exchange in 0.8~4m/s at 5 upside air outlet 6 of vertical ventilation pipe
Meet requirement of the personnel to blowing feeling beyond 1 meter away from equipment at the same time.
In summer cooling operating mode, when pipeline external surface temperature is less than the dew-point temperature of room air, the current of condensation
Into in the condensate groove 9 of lower part, and finally drain from condensate discharge pipe, realize the cooling under wet cooling condition.
When system uses same set of heat pump unit in the cold and heat source in summer, winter, the cold and heat supply end-equipment in room
A kind of enhancing heat exchange type radiation and convection cool-heat-exchanger can 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 rise, density reduce
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, so circulation, constantly
Cold is provided for room.To improve the cooling ability of 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
Acted on to enhanced heat exchange.Strengthen radiation and convection cool-heat-exchanger when to room cooling, the condensation water that its surface produces is by wrapping up
After condensate groove 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 contrast, to realize the conversion of flow direction, can be completed in heat pump unit side by the switching of valve.
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
During 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
, 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 change of indoor cold heat load for so making equipment match, so as to ensure room temperature
Maintain in the range of human comfort.
