Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described。
A kind of heat recovering ventilation apparatus, including heat exchanger 1, pressure fan 2 and exhaust blower 3。Heat exchanger 1 is installed in main case 4, and the front side of heat exchanger 1 is provided with roughing efficiency air filter 5 and high efficiency particulate air filter 6。Pressure fan 2 is installed in air-supply casing 7, and exhaust blower 3 is installed in air draft casing 8。Air-supply casing 7 is installed on the rear side of main case 4, and air draft casing 8 is installed on the upside of main case 4, and the bottom of main case 4 is provided with air draft import 31, and the lower section of heat exchanger 1 is located in air draft import 31, and the front side of main case 4 is provided with fresh inlet 21。
Specifically, main case 4, air-supply casing 7 and air draft casing 8 adopt metal material or the nonmetallic materials such as plastics, wood-based plate to make。In order to increase intensity, the inwall of main case 4 is provided with reinforcement, to prevent main case 4 from deforming。
In the present embodiment, new wind is transverse air-intake, and new wind exports 22 through new wind after passing sequentially through roughing efficiency air filter 5 arranged in parallel, high efficiency particulate air filter 6, heat exchanger 1 and pressure fan 2 and sends。The exit of pressure fan 2 is additionally provided with rotatable wind deflector 9, and wind deflector 9 is rotated by being arranged on the wind-guiding blower fan 91 of its side, to regulate the air supply direction of new wind。Wind deflector 9 in the present embodiment has two, lays respectively at the left and right sides, top of air-supply casing 7。Pressure fan 2 adopts the mode of convulsion, and its windage is little, and energy consumption is little, blows more smooth and easy。Air draft is vertical air intake, sends through wind exhausting outlet 32 after passing sequentially through heat exchanger 1 and exhaust blower 3。
Preferably, heat exchanger 1 is heat-exchangers of the plate type, including fixed mount 11 and multiple heat exchanger plate 12 with guiding gutter, heat exchanger plate 12 is arranged in parallel to be arranged in fixed mount 11, gap between heat exchanger plate 12 and heat exchanger plate 12 forms fresh air channel, forms air exhaust passage between the guiding gutter of heat exchanger plate 12 with the guiding gutter of adjacent heat exchanger plate 12。In the present embodiment, fixed mount 11 is the framework of square hollow structure, and fixed mount 11 is provided with reinforcement, to prevent fixed mount 11 from deforming。Heat exchanger plate 12 adopts super thin aluminum sheet to make, and its surface stamps out guiding gutter, and the shape of guiding gutter can be circle, annular, rhombus, square etc., and the present embodiment is preferably diamond-mesh face, it is possible to ensureing the Uniform Flow of air draft, windage is little, and air draft is smooth and easy。Gap between adjacent heat exchanger plates 12 is narrow, to improve heat exchanger effectiveness。
Heat exchanger 1 adopts reverse-flow heat exchange structure so that send through new wind outlet 22 and wind exhausting outlet 32 respectively after the new wind of pressure fan 2 and the air draft vertical interlaced of exhaust blower 3。Reverse-flow heat exchange structure particularly as follows: be provided with flow apron 13 in the both sides of heat exchanger 1, the inside being specifically located at fixed mount 11 of flow apron 13 and be positioned at the both sides of heat exchanger plate 12 part。Wherein, directed fluid inlet 14 is formed between flow apron 13 and the heat exchanger plate 12 of side, diversion outlet 15 is formed between flow apron 13 and the heat exchanger plate 12 of opposite side, in other words, directed fluid inlet 14 is positioned at the upstream of heat exchanger 1 on air-flow direction, diversion outlet 15 is positioned at the downstream of heat exchanger 1 on air-flow direction so that new wind is vertically through fresh air channel。Alternatively, flow apron 13 can be adopted the mode being screwed and is arranged on fixed mount 11, it would however also be possible to employ sliding structure is arranged on fixed mount 11, to facilitate adjustment。
When the fresh air channel that new wind passes sequentially through roughing efficiency air filter 5 and high efficiency particulate air filter 6 enters in heat exchanger 1, form air-flow straight down。And air draft runs vertically upward from the bottom of heat exchanger 1 along air exhaust passage, becoming reverse-flow heat exchange with new pathogenic wind manifold straight down, utilization rate of waste heat is high, and energy-saving effect is much better than the new blower fan of prior art。The structural design of the heat-exchangers of the plate type 1 of the present embodiment is unique rationally, heat exchange path is more tortuous, swap time is longer, adopts counter-flow heat exchange, improves utilization rate of waste heat, good energy-conserving effect。
Pressure fan 2 and exhaust blower 3 are ultrathin centrifugal blower, it is preferable that the external diameter of pressure fan 2 and thickness ratio is for 5:1, and the external diameter of exhaust blower 3 and thickness ratio is for 8:1。This ultrathin centrifugal blower has that volume is little, noise is little, resistance is little, high-power advantage, is effectively reduced volume, saves space, reduces energy consumption。
In the present embodiment, main case 4, air-supply casing 7, air draft casing 8 all adopt the mode molding of overall punching press or integral molded plastic, and main case 4 and air-supply are connected with each other by clamping and the mode being spirally connected between casing 7, air draft casing 8, with easy assembly and disassembly。Adopt integral forming technique and detachable connection, part can be efficiently reduced, shorten the production cycle, save material, significantly decrease production cost, improve production efficiency。
New blower fan according to this utility model embodiment, including the heat recovering ventilation apparatus according to this utility model previous embodiment。Thus, improve the utilization rate of waste heat of new blower fan, good energy-conserving effect, heat exchanger effectiveness is high。
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, it is clear that this utility model can be carried out various change modification without deviating from spirit and scope of the present utility model by those skilled in the art。If these amendments of the present utility model and modification being belonged within the scope of this utility model claim and equivalent technologies thereof, belong to protection domain of the present utility model。
