Description
Technical field
The utility model relates to a kind of forced air cooler cooling core, particularly a kind of Novel air cooler cooling core.
Background technology
The national economic development be unable to do without electric power industry development, China's power industry is in recent decades developed rapidly, especially have in the Northwest and enrich hydropower resource, in the mine mouth thermal power generation in the producing coal area such as Xinjiang, Shanxi, and these abundant greens, clean energy resource to be transported to East China, the industrial area such as coastal, extra-high pressure, vast capacity power transmission and transformation conveying circuit must be had.China successively builds up several ± 800,000 volts direct current transportation and 1,000,000 volts of transmission line of alternation currents in recent years, and one of key equipment is exactly super-pressure, jumbo step up and step down transformer in these super-pressure, large capacity transmission circuit, because transformer capacity is large, generation loss is large, heat is also large, so compact forced oil generally will be adopted to follow forced air cooler (hereinafter referred to as forced air cooler), carry out cooling transformer body, thus guarantee transformer in longtime running in transformer oil temperature keep normal condition, reach safe and reliable operation.
This patent is that in the forced air cooler cooling core for super large cooling capacity, cooling tube evenly can position by designing requirement, fix, not because cooling tube length is long, there is flexural deformation, mutually kink between causing about cooling tube and cooling tube fin, block vent passages, affect forced air cooler cooling effectiveness.

The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of Novel air cooler cooling core, comprise the shell structure, cooling tube and the dividing plate that are formed by end plate and sidewall, some row's cooling tubes are arranged in parallel is positioned at shell structure inside, adjacent two row's cooling tubes pass through baffle interval, it is characterized in that: described dividing plate is the hard plate of undulate structure, the wave groove of dividing plate both sides is respectively the arc groove with cooling tube form fit.
As further improvement of the utility model, described dividing plate one side is also provided with some baffle plates extended along cooling tube radial direction, each baffle plate is distributed on the crest of each wave of dividing plate respectively, and each baffle plate is just located between two adjacent cooling tube periphery faces and forms baffle.
As further improvement of the utility model, described baffle plate is the square plate being positioned at cooling core short transverse centre position.
As further improvement of the utility model, two adjacent cooling tube median planes are crossed in described dividing plate overhead gage end, some dividing plates arrange in the same way or arrange in opposite directions, also be provided with an engagement plate, this engagement plate is in the wavy shaped configuration identical with dividing plate, this engagement plate is provided with the side in baffle plate direction or between two dividing plates arranged in opposite directions, a side surface of the sidewall contact of dividing plate and shell structure distributes without baffle plate at the dividing plate arranged in the same way.
As further improvement of the utility model, described dividing plate and engagement plate are the thick steel plate of 2mm.
As further improvement of the utility model, described baffle plate is the steel plate that 2mm is thick.
The beneficial effects of the utility model are: dividing plate of the present utility model adopts 2mm steel plate punched to form wavy shaped configuration, cooling tube is firmly limited in the circular groove of adjacent separator, dividing plate has the baffle plate being formed and extend along cooling tube radial direction, baffle plate is further by also spaced apart for adjacent cooling tube in every row, every like this two adjacent cooling tubes are all spaced apart, effectively prevent adjacent cooling tube fin mutually to kink together, ensure that on high-power forced air cooler, cooling duct is unimpeded, ensure that high-power forced air cooler cooling effectiveness can reach designing requirement, and the utility model structure is simple, production cost is low, produce and easy to assembly.
