Example 1

Referring to fig. 1 to 3, the present embodiment provides a combined heat exchanger unit, which is sequentially provided with a fan module 1, a humidifying module 2, a heat exchange module 3 and an air inlet module 4 from front to back.

The fan module 1 comprises a fan fixing frame 101 and a plurality of air supply fans 102 arranged on the fan fixing frame 101. The humidifying module 2 comprises a wet film fixing frame 201, a wet film 202 arranged in the wet film fixing frame 201, a humidifying water pan 203 arranged below the wet film 202, and a ventilation support plate 204 arranged in the wet film fixing frame 201. The heat exchange module 3 comprises a heat exchanger fixing frame 301, a fin heat exchange tube 302 arranged in the heat exchanger fixing frame 301, and a heat exchange water receiving disc 303 arranged below the fin heat exchange tube 302.

Further, the wet film fixing frame 201 is close to the surface of the fan fixing frame 101, one end of the wet film fixing frame is hinged to the fan fixing frame 101, and the other end of the wet film fixing frame is clamped and/or fastened with the fan fixing frame 101;

the wet film fixing frame 201 is close to the surface of the heat exchanger fixing frame 301, one end of the wet film fixing frame is hinged to the heat exchanger fixing frame 301, and the other end of the wet film fixing frame is clamped and/or fastened with the heat exchanger fixing frame 301.

Optionally, the two adjacent modules are hinged through hinges and the like.

In general, the humidification module 2 rotates relative to the heat exchange module 3 to be attached to the heat exchange module 3 (the free ends of the humidification module 2 are fastened by clamping and/or fastening), the fan module 1 rotates relative to the humidification module 2 to be attached to the humidification module 2 (the free ends of the humidification module 2 are fastened by clamping and/or fastening), and at this time, the fan module 1, the humidification module 2, the heat exchange module 3 and the air intake module 4 form a whole.

When the indoor space needs to be cooled, the air supply fan 102 is started, under the driving action of the air supply fan 102, air around the air inlet module 4 enters the heat exchange module 3 through the air inlet module 4, the temperature is reduced after the cold in the fin heat exchange tube 302 is absorbed, the moisture content is improved through the wet film 202, and finally the air is blown out through the fan module 1, so that the indoor space is cooled;

when the combined heat exchanger unit needs to be overhauled, the air supply fan 102 and the compressor are closed, the fan module 1 and/or the humidification module 2 can be selectively turned and opened according to the needs, and then the air supply fan 102 at the inner side of the fan fixing frame 101, the wet film 202 in the wet film fixing frame 201, the fin heat exchange tubes 302 in the heat exchanger fixing frame 301 and the like are overhauled or cleaned, the whole combined heat exchanger unit does not need to be detached from the wall, the operation is simple and convenient, and after the overhauling or cleaning is finished, the opened module is closed again.

In this embodiment, the air supply fan 102 is an axial flow fan. It should be noted that, the conventional air supply fan 102 is mostly a cross flow fan, and under the condition of the same power, the air output of the cross flow fan is lower, and when the rotating module structure in this embodiment is adopted, the air supply fan 102 can be set as an axial flow fan, which can reduce the thickness dimension of the fan module 1 and improve the air output.

The ventilation support plate 204 is used for fixing the wet film 202, and the ventilation holes of the ventilation support plate 204 are normally open, and the humidification function is turned on and off, which is controlled by a water inlet electromagnetic valve or other valve of the wet film 202.

In this embodiment, the air intake module 4 includes an air intake frame 401, a wind deflector 402, and a fixing block 403.

In this embodiment, the heat exchange module 3 is tightly connected with the air intake module 4, that is, the heat exchange module 3 cannot be rotated to open the air intake module 4; in some other embodiments, one end of the heat exchange module 3 is hinged to the air intake module 4, and the other end is clamped and/or fastened to the air intake module 4, i.e. the heat exchange module 3 may be turned to open the air intake module 4.

Optionally, the air inlet frame 401 is provided with a top air inlet 4011, a back air inlet 4012, and an air outlet 4013 near the heat exchange module 3. The wind shield 402 is rotatably connected with the air inlet frame 401; the wind shield 402 has a back air inlet state that rotates relative to the air inlet frame 401 to completely cover the top air inlet 4011, and a top air inlet state that rotates relative to the air inlet frame 401 to completely cover the back air inlet 4012.

Alternatively, the wind deflector 402 may be mounted on a shaft with a large rotation damping, and a large external force is required to rotate the wind deflector 402, so that the wind force of the conventional wind is insufficient to rotate the wind deflector 402, thereby realizing positioning of the wind deflector 402; alternatively, the wind deflector 402 may be mounted on a driving shaft of a motor, and the rotation angle control and positioning of the wind deflector 402 may be controlled by the motor.

A sliding sleeve 4014 is arranged on the side surface of the air inlet frame body 401, a sliding groove is arranged on the back surface of the sliding sleeve 4014, and a plurality of positioning holes 4015 which are communicated with the sliding groove to the outer space of the sliding groove are arranged on the side surface of the sliding sleeve 4014; the fixing block 403 is inserted into the chute and fixedly connected with the sliding sleeve 4014, and a plurality of fastening holes 4031 which are fixedly connected with any one of the positioning holes 4015 are formed in the fixing block 403; wherein, the arrangement direction of each positioning hole 4015 is parallel to the sliding direction of the fixed block 403 and the sliding chute; the fixing block 403 and the air inlet frame 401 can be positioned relatively by using bolts and other fasteners to pass through any positioning holes 4015 and then be connected with the fastening holes 4031 in a threaded manner.

The using method of the air inlet module 4 is as follows:

s10: when the air inlet device is specifically used, the fixing block 403 is fixed on a wall, and then the air inlet frame 401 is slid back and forth, so that the distance between the back air inlet 4012 of the air inlet frame 401 and the wall can be adjusted, and the back air inlet quantity is further adjusted; after the air inlet frame 401 is slid to a proper position, a fastener such as a bolt passes through any positioning hole 4015 and is then fastened and connected with the fastening hole 4031, so that the relative fixation of the fixing block 403 and the air inlet frame 401 can be completed;

s20: then, the wind guard 402 is rotated to adjust the air intake of the top air intake 4011 and the back air intake 4012, and according to the application scenario, the full back air intake (i.e. back air intake state), the full top air intake (i.e. top air intake state) or the mixed air intake (the rotation angle of the wind guard 402 is in an inclined state) can be selected.

Further, the number of the blower fans 102 is at least two, and the working states (including rotation speed, steering, etc.) of the blower fans 102 are independent from each other.

Further, the back side air inlet 4012 may be communicated to the outdoor space so as to add fresh air to the indoor space. Accordingly, when the wind screen 402 is in a vertical top air inlet state, no fresh air is introduced, and circulation is performed by completely relying on indoor return air; when the wind shield 402 is in a horizontal back air inlet state, indoor return air is not introduced, and the fresh air is completely sent into the heat exchange module 3 by outdoor fresh air; further, at this time, part or all of the air supply fans 102 in the fan module 1 are controlled to reversely rotate, and indoor air can be reversely blown to the outside to balance indoor and outdoor air pressure (if the air supply fans are installed on a closed cabinet, the air pressure in the cabinet can be increased due to small space and high temperature, and at this time, the air supply fans 102 are controlled to reversely rotate); when the wind deflector 402 is in an inclined state, both fresh air and indoor return air are introduced and circulated using a mixed air mode. The air quantity of the fresh air can be controlled by adjusting the inclination angle of the wind shield 402.

It should be noted that, in this embodiment, the combined heat exchange unit may be used indoors, i.e. as an "internal unit", and of course, in some other embodiments, may also be used as an "external unit", which is not limited in this invention. Further, the "inner machine" and the "outer machine" are also relative concepts, and based on the anti-theft requirement, the compressor may be disposed in the indoor "inner machine" under some special working conditions, so the inner machine in the present invention is not limited to the air supply device with only the fin heat exchange tube 302 and the air supply fan 102.

Further, when the air conditioning unit enters a defrosting state or a heating state, the fin heat exchange tube 302 in the combined heat exchange unit can be used as a condenser, so that the fin heat exchange tube 302 can also be a condenser under certain working conditions, and the invention is described by using the integral structure and working principle of the fin heat exchange tube 302 for convenience of description and understanding, but the naming does not mean that the protection scope is limited.

The combined heat exchanger unit provided by the embodiment has the following advantages:

(1) the fan module 1 and the humidifying module 2 are of rotatable opening type structures, so that key components such as the air supply fan 102, the wet film 202, the fin heat exchange tube 302 and the like can be overhauled and cleaned without disassembling the whole combined heat exchange unit, and the operation is simple and convenient;

(2) the filter modules and the like can be added, and the modules are sequentially hinged, so that expansion and deletion of various functional modules are facilitated, for example, a filter membrane group (comprising a filter frame body and a filter screen arranged in the filter frame body) and the like can be additionally arranged on the back surface of the heat exchange module 3;

(3) the fin heat exchange tube 302 is in a flat plate shape, so that compared with the traditional assembly and combination of a plurality of heat exchangers, the complexity of production and manufacture is reduced, and the cleaning difficulty is reduced; the fin heat exchange tubes 302 are placed in parallel with the air supply fan 102, and compared with the traditional layout form (the cross flow fan is arranged below the evaporator), the risk of blowing water is reduced;

(4) the distance between the air inlet module 4 and the wall surface is adjustable, so that the air inlet module is suitable for different installation environments and distance requirements; the refrigerant joint at the end part of the fin heat exchange tube 302 is arranged at the back of the heat exchange module 3, so that the distance between the refrigerant joint and the installation wall is adjustable, and compared with the refrigerant joint of the traditional internal machine (the traditional refrigerant joint is arranged between a unit and the wall and has no gap), the installation and the disassembly modes are more flexible; the brought adjustable distance is beneficial to the additional improvement of the subsequent fresh air functional area;

(5) the rotation angle of the wind shield 402 is adjustable, so that the switching adjustment of an air inlet mode is realized, and compared with the traditional fresh air function, the wind shield has larger fresh air quantity and safer fresh air temperature, and condensation is avoided;

(6) the fan module 1 adopts a plurality of axial flow fans, and can reversely blow off dust on the evaporator and the filter screen by controlling the inversion of the axial flow fans, so as to realize a self-cleaning function; the air can be exhausted outwards, so that the indoor pressure and the outdoor pressure are balanced, and fresh air can enter more smoothly; the functions of the fans are increased, and a group of fans realize refrigeration/heating, dust removal cleaning and fresh air.
