Abstract
The utility model relates to an evaporative condenser adopting a wavy fin and a flat pipe. The evaporative condenser adopting the wavy fin and the flat pipe comprises a condensing coil and a radiating fin; the condensing coil is a flat pipe; and the radiating fin is a wavy radiating fin which passes through the surface of the condensing coil in a sleeving way. According to the evaporative condenser adopting the wavy fin and the flat pipe, after the condensing coil is replaced by the flat pipe, the maximum diameter of the flat pipe is still in line with the diameter of a round pipe in the prior art, therefore, the volume of an inner chamber of the flat pipe is reduced, and the quantity of a poured refrigerant is relatively reduced; by combination with the wavy radiating fin passing through the surface of the flat pipe in the sleeving way, turbulent flow is generated by the air which flows through the surface of the condensing coil, so that the heat exchange capacity of the air with the fin can be improved, and the purposes of effectively reducing the refrigerant charge, reducing the cost and improving the heat exchange efficiency can be finally realized.
Description
Technical field
The utility model relates to the evaporative condenser technical field, particularly a kind ofly adopts Wavelike finned and evaporative condenser flat tube.
Background technology
China Patent No. 201020558413.9 discloses the evaporative condenser that a kind of refrigeration unit is used on April 20th, 2011, it comprises blower fan, shell and is located at the interior condenser coil of shell body, shell is provided with air inlet and air outlet, blower fan is located at the air outlet place of shell, the condenser coil below is provided with cistern, and the condenser coil periphery is provided with shower nozzle.The condenser coil of this structure is pipe, and the pipe cavity volume is larger, and refrigerant charge is corresponding increase also.In addition, what the condenser coil surface wore is straight sheet radiating fin, and straight sheet radiating fin does not produce flow-disturbing to the air by condenser coil, and the exchange capability of heat of air and fin is not improved.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provide a kind of simple and reasonable, effectively reduce refrigerant charge, reduce windage, reduce cost, improve the evaporative condenser of the Wavelike finned and flat tube of the employing of heat exchange efficiency, to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this.
A kind ofly adopt Wavelike finned and evaporative condenser flat tube, comprise condenser coil and radiating fin, it is characterized in that: described condenser coil is flat tube, and radiating fin is the waveform radiating fin, and the waveform radiating fin is set on the condenser coil surface.
As a kind of scheme more specifically, described condenser coil is that end face is oblong flat tube.
The height H of described condenser coil inner chamber and the ratio of width W are 3/1 to 4/1.
Described waveform radiating fin top and bottom are respectively equipped with upper overturning and lower flange.Upper overturning can will flow through the air on condenser coil surface be guided out outside the evaporative condenser, the air that lower flange can blow blower fan is inducted into evaporative condenser.
The crest of described waveform radiating fin and wave trough position are provided with the dash limit.
Described dash limit is lower curved arc shape or has a down dip planar.
The surface of described waveform radiating fin is provided with the reinforcement convex tendon.
Described evaporative condenser also comprises shell, blower fan, shower nozzle, water pump and header tank, described condenser coil setting in the enclosure, the waveform radiating fin that is set on the condenser coil surface is dislocatedly distributed, shower nozzle is arranged on the condenser coil top, also is communicated with header tank by water pipe, water pump, and header tank is arranged on the condenser coil below.Blower fan generally can be installed in evaporative condenser above or below, when assembling is above evaporative condenser, the blast at condenser coil place is that negative pressure is (opposite, when assembling is below evaporative condenser, the blast at condenser coil place is malleation), the air condenser coil of flowing through from bottom to top, the condenser coil width should with blower fan exhausting or blowing air to consistent, to reduce front face area, reduce windage.
As another kind of scheme more specifically, described condenser coil is the flat tube of end face ovalize.
The beneficial effects of the utility model are as follows:
(1) because after condenser coil uses flat tube instead, the maximum caliber of flat tube is still consistent with pipe caliber in the prior art, so comparatively speaking, the volume of flat tube inner chamber reduces, refrigerant charge also reduces relatively, and again in conjunction with the waveform radiating fin that is set on the flat tube surface, the waveform radiating fin makes the air on the condenser coil surface of flowing through produce flow-disturbing, strengthen the exchange capability of heat of air and fin, finally reach the purpose of effective minimizing refrigerant charge, reduction cost and raising heat exchange efficiency;
(2) flat tube mainly is divided into end face and is Long Circle and oval two kinds, and the width of body is less than the body height, and the width of body towards air-flow direction, is realized reducing front face area, reduces windage, accelerates Air Flow, improves the purpose of heat transfer effect;
(3) because trickle (water from top to bottom) is arranged at evaporative condenser top, the blower fan blow air is from bottom to top passed through evaporative condenser, have the water droplet evaporative condenser that flies out, by being provided with the dash limit at the waveform radiating fin, water droplet can be blocked in the dash limit, makes it to return the header tank below the evaporative condenser.
