Abstract
The utility model discloses a low noise heat exchanger which comprises a box body. A top cover used for sealing is arranged on the box body. An inner circulation wind channel and an outer circulation wind channel are arranged in the box body. An inner circulation fan is arranged in the inner circulation wind channel. An outer circulation fan is arranged in the outer circulation wind channel. A sound absorption sponge is arranged on the surface in the top cover. The low noise heat exchanger is simple in structure and ingenious in design. When the low noise heat exchanger is used, environmental wind is absorbed into the inner circulation wind channel through a wind inlet by the outer circulation fan, then enters into a transition cavity chamber, and is discharged into the outer circulation wind channel through a heat exchanging core and into environment from a wind outlet. Due to the sound absorption sponge is arranged on the inner surface of the top cover, wind current runs in the wind channels in a circulation mode, the sponge eliminates noise, and the noise can be reduced by 3-5 dB.
Description
Technical field
The utility model relates to the interchanger technical field, particularly relates to a kind of low-noise heating interchanger.
Background technology
At present the low-noise heating interchanger in use, the workflow diagram of prior art as shown in Figure 1, ambient wind is directly sucked in the chamber, outer circulation fan 1 place by outer circulation fan 1, and then directly is discharged in the environment through the heat exchange core heat exchange; The air of interior circulation side also is directly to be sucked in the interior chamber, circulating fan 2 place by interior circulating fan 2, and then directly is discharged to interior circulation side through the heat exchange core heat exchange.The low-noise heating interchanger of this structure, the noise that produces when operation is larger.
In sum, for the defective of prior art, the present a novel low-noise heating interchanger produced of my company, thus solve above-mentioned problem.
The utility model content
The technical problem that the utility model mainly solves provides a kind of low-noise heating interchanger, the larger problem of noise that produces in the time of can solving traditional low-noise heating interchanger operation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of low-noise heating interchanger, comprise casing, be provided with the top cover for sealing above the described casing, be provided with interior circulation air path and outer circulating air duct in the casing, be provided with interior circulating fan in the described interior circulation air path, be provided with the outer circulation blower fan in the outer circulating air duct, the surface in the described top cover is provided with the sound-absorbing sponge.
In preferred embodiment of the utility model, described casing is provided with the air inlet for the outer circulating air duct air intake.
In preferred embodiment of the utility model, described casing is provided with the air outlet for interior circulation air path air-out.
In preferred embodiment of the utility model, be provided with transition chamber thereof between described interior circulation air path and the outer circulating air duct.
In preferred embodiment of the utility model, be provided with heat exchange core in the described transition chamber thereof.
The beneficial effects of the utility model are: the utility model is simple in structure, design ingenious, circulation air path in ambient wind is sucked from air inlet by the outer circulation blower fan first in use, after enter again transition chamber thereof, being discharged to outer circulating air duct through heat exchange core, then be discharged to the environment from air outlet, owing to arrange the sound-absorbing sponge at the top cover inner surface, air-flow detours in the air channel like this, adds sponge to the subduing of sound, and noise can reduce about 3 ~ 5dB.
Description of drawings
The workflow diagram of Fig. 1 prior art;
Fig. 2 schematic diagram of the present utility model;
Fig. 3 solid of the present utility model is attempted.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of larger problem of noise that produces can solve the operation of traditional low-noise heating interchanger the time, thereby a kind of low-noise heating interchanger that proposes, comprise casing 1, be provided with the top cover 2 for sealing above the described casing 1, be provided with interior circulation air path 3 and outer circulating air duct 4 in the casing 1, be provided with interior circulating fan 5 in the described interior circulation air path 3, be provided with outer circulation blower fan 6 in the outer circulating air duct 4, the surface in the described top cover 2 is provided with sound-absorbing sponge 7.
It is worth mentioning that present embodiment is provided with air inlet 8 for outer circulating air duct 4 air intakes for casing 1, casing 1 is provided with the air outlet 9 for interior circulation air path 3 air-out, is provided with transition chamber thereof 10 between described interior circulation air path 3 and the outer circulating air duct 4.Be provided with heat exchange core in the described transition chamber thereof 10.
Based on above-mentioned, the utility model is simple in structure, design ingenious, circulation air path 3 in ambient wind is sucked from air inlet 8 by outer circulation blower fan 6 first in use, after enter again transition chamber thereof, be discharged to outer circulating air duct 4 through heat exchange core, then be discharged to the environment from air outlet 9, owing to arrange sound-absorbing sponge 7 at top cover 2 inner surfaces, air-flow detours in the air channel like this, add sponge to the subduing of sound, noise can reduce about 3 ~ 5dB.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
