The utility model provides a new fan, includes casing 10 and installs fan subassembly 20, heat exchange element 30 in casing 10, and this new fan introduces outdoor new trend indoor to introduce indoor dirty wind outdoors, carry out effectual circulation with the room air, realize indoor outer air convection, improve user comfort, below, will explain in detail above-mentioned part:

the casing 10 is formed with a fresh air inlet 11 and a fresh air outlet 12 for fresh air circulation, and a dirty air inlet 13 and a dirty air outlet 14 for dirty air circulation, and the fresh air and the dirty air are independent of each other and circulate in opposite directions in the casing 10.

Specifically, a fresh air channel 15 is formed between the fresh air inlet 11 and the fresh air outlet 12, and a dirty air channel 16 is formed between the dirty air inlet 13 and the dirty air outlet 14; fresh air enters the fresh air channel 15 from the outdoor through the fresh air inlet 11 and is output to the indoor through the fresh air outlet 12, and indoor dirty air enters the dirty air channel 16 through the dirty air inlet 13 and is output to the outdoor through the dirty air outlet 14.

Be formed with a plurality of lateral walls on the casing 10, new trend entry 11 and foul wind export 14 all are located casing 10's first lateral wall 17, new trend export 12 and foul wind entry 13 are located casing 10's second lateral wall 18, first lateral wall 17 is located the offside of second lateral wall 18, under the installation status, new trend entry 11 and foul wind export 14 are close to outdoor side, new trend export 12 and foul wind entry 13 are close to indoor side, be convenient for export indoor foul wind to outdoor, introduce outdoor new trend indoor.

The transportation of new trend and foul wind all is accomplished through fan subassembly 20 in casing 10, fan subassembly 20 provides the power of water conservancy diversion for new trend and foul wind, fan subassembly 20 sets up in casing 10, a flow for driving new trend and foul wind, it includes motor 21, transmission shaft 26 and two fans, motor 21 fixes in casing 10, motor 21's both sides are connected with a transmission shaft 26 respectively, two transmission shafts 26 are synchronous rotation under motor 21's drive, be formed with a fan on two transmission shafts 26 respectively, be defined as first fan 22 and second fan 23 respectively, the installation opposite direction of first fan 22 and second fan 23, make the water conservancy diversion opposite direction of first fan 22 with second fan 23, and then make new trend and foul wind circulate along different directions.

The motor 21 drives the two fans together, so that the overall size of the fan assembly 20 can be effectively reduced, the miniaturization of the new fan is facilitated, when the motor 21 runs, the motor 21 rotates to drive the first fan 22 and the second fan 23 to rotate, the fans rotate to bring air flow, and the installation directions of the first fan 22 and the second fan 23 are completely opposite, so that the two wind directions are completely opposite.

In order to improve the energy-saving effect of the fresh air fan, a heat exchange element 30 is further arranged in the shell 10, the heat exchange element 30 penetrates through the fresh air channel 15 and the dirty air channel 16, heat is transmitted between the fresh air and the dirty air, and the heat exchange element is used for heat exchange between the fresh air and the dirty air.

The first fan 22 and the second fan 23 are formed with fan volutes, the flow guiding directions of the first fan 22 and the second fan 23 on the transmission shaft 26 are opposite, that is, the air inlet side of the first fan 22 and the air inlet side of the second fan 23 are in opposite directions, specifically, the first fan 22 and the second fan 23 are both formed with an air inlet 25 and an air outlet 24, the air inlet 25 on the first fan 22 faces the fresh air inlet 11, and the air outlet 24 faces the fresh air outlet 12, so that fresh air is conveniently introduced from the fresh air inlet 11 and is output from the air outlet 24, and is finally output from the fresh air outlet 12.

The second fan 23 has an inlet 25 facing the dirty air inlet 13 and an outlet 24 facing the dirty air outlet 14, and draws in dirty air from the dirty air inlet 13 and outputs the dirty air in the direction of the dirty air outlet 14.

The motor 21 is fixed in the fresh air duct 15 or the dirty air duct 16, and the first fan 22 and the second fan 23 are respectively located in the fresh air duct 15 and the dirty air duct 16.

The heat exchange element 30 is located between the fan assembly 20 and the first side wall 17, the heat exchange element 30 is a heat pipe, the heat pipe utilizes a phase change process (namely, utilizing evaporation latent heat and condensation latent heat of liquid) of medium which is evaporated at a hot end and condensed at a cold end to quickly conduct heat, and the heat pipe generally comprises a pipe shell, a liquid absorption core and an end cover. When one end of the heat pipe is heated, the liquid in the capillary tube is quickly vaporized, the vapor flows to the other end under the power of heat diffusion, and is condensed at the cold end to release heat, and the liquid flows back to the evaporation end along the porous material under the action of capillary action, so that the circulation is not stopped until the temperatures of the two ends of the heat pipe are equal, a closed circulation is completed, and the purpose of heat exchange of fresh air and dirty air is realized.

In order to maximize the utilization of the casing 10, the whole inner cavity of the casing 10 is divided into a fresh air channel 15 and a dirty air channel 16 by a partition plate 40, the installation direction of the heat exchange element 30 is perpendicular to the partition plate 40, and the casing and the partition plate 40 are made of sheet metal parts.

The specific working process is as follows:

when the motor 21 is turned on, the rotation of the first fan causes outdoor fresh air to enter the housing 10 through the fresh air inlet 11, pass through the fresh air channel 15, and be guided by the fresh air fan and the volute and then be output to the indoor through the fresh air outlet 12. Meanwhile, the indoor dirty air passes through the dirty air inlet 13 (enters the dirty air passage 16 of the casing 10, is sucked by the dirty air side second fan 23 and the scroll casing, and is then discharged to the outside through the dirty air outlet 14.

When fresh air and dirty air on two sides move in the shell 10, the air on two sides exchanges heat through the heat exchange element 30, so that the unit is more energy-saving.

The technical scheme that this application relates has reduced the quantity of new fan motor 21 through the design of biax motor, and consequently the size of new fan is littleer, make things convenient for the later stage maintenance, and the cost of installation manufacturing is lower, and the heat pipe is compared in the new fan of conventionality and is increased the heat recovery function, and the low power dissipation is more energy-conserving.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention, and therefore, the scope of the present invention shall be subject to the claims.
