The operation flow of the cooling mode is the same as that of the heating mode, except that the form change of the refrigerant and the heat exchange condition are opposite.

The internal installation space of the air source heat pump unit is generally divided into two parts, one part is used for installing the compressor 4 and the titanium tube heat exchanger 9, the other part is used for installing the fin heat exchanger 1 and the air guide assembly, the air guide assembly generally comprises a fan 6, air guide blades 5 and an air guide ring 2, and external air enters the unit after heat exchange of the fin heat exchanger 1 and is discharged under the action of the fan 6, the air guide blades 5 and the air guide ring 2.

As shown in fig. 1 to 6, the present embodiment provides an air source heat pump unit including: the fin heat exchanger 1, the wind-guiding circle 2 and end plate 3, the end plate 3 install respectively in the both ends of fin heat exchanger 1 horizontal direction, fin heat exchanger 1 has air inlet side and air-out side, the wind-guiding circle 2 install in the air-out side of fin heat exchanger 1, wind-guiding circle 2 includes main part 201, and from the both ends of main part 201 for the wind-guiding part 202 that fin heat exchanger 1 direction extends to form, two wind-guiding part 202 respectively with two end plate 3 butt.

Based on the above scheme, an air inlet cavity capable of air inlet is formed between the main body part 201 and the two air guide parts 202, the air inlet cavity corresponds to the air outlet side of the fin heat exchanger 1, external air enters the air inlet cavity through the air outlet side after heat exchange through the air inlet side of the fin heat exchanger 1, and in the process that the air enters the air inlet cavity, in order to avoid slipping of the air from two sides of the air inlet cavity, the air guide parts 202 are specially designed to be abutted with end plates 3 arranged at two ends of the fin heat exchanger 1 so as to seal the air inlet cavity, and sealing does not mean that the whole air inlet cavity is completely sealed, specifically means that two sides in the horizontal direction are sealed so as to ensure that the air cannot slip from two ends and avoid the phenomenon of air leakage and air cross; through the cooperation of the mounting positions of the wind guide ring 2, the end plate 3 and the fin heat exchanger 1, unified guiding of wind flow direction is realized, the wind quantity is preserved to the greatest extent, and the unified wind direction can effectively prevent noise generated by mutual collision among wind at different wind speeds, so that the overall performance of the heat pump unit is improved.

The end plate 3 is designed to have the first plate 301 and the second plate 302, so as to avoid the situation that the air guide 202 generates acting force on the fin heat exchanger 1 when the end plate 3 is abutted against the air guide 202, which is equivalent to the situation that the first plate 301 and the second plate 302 are matched to be abutted against the air guide 202 so that the fin heat exchanger 1 and the air guide 202 are effectively avoided, and the situation that the fin heat exchanger 1 is deformed due to the abutting of the air guide 202 is prevented. In addition, the fin heat exchanger 1 includes a plurality of heat exchange tubes 101, and tube holes 303 corresponding to the heat exchange tubes 101 are formed in the first plate 301.

The first plate 301 and the second plate 302 are vertically connected, and the extending direction of the second plate 302 includes two specific cases, the first case is that the second plate 302 at two ends extends inwards; the second is outwardly extending, i.e., the second plate 302 at both ends extends away from. The first extension scheme can avoid that the second plate 302 occupies too much installation space in the horizontal direction, so that the structural connection in the heat pump unit is more compact, and the purpose of saving the installation space can be achieved. The second extension scheme is equivalent to that the second plate 302 is staggered with the air outlet side of the fin heat exchanger 1, so that the air exchanged by the fin heat exchanger 1 can not be blocked and directly enter the air inlet cavity, and the maximum utilization of the air quantity is ensured.

Considering that the air guide part 202 may contact the fin heat exchanger 1 when abutting against the second plate 302, the second plate 302 and the fin heat exchanger 1 are arranged at intervals, which can be understood that the second plate 302 and the fin heat exchanger 1 are not on the same plane, so that when the air guide part 202 abuts against the second plate 302, the air guide part 202 is ensured not to contact any position with the fin heat exchanger 1, and accidents such as deformation of the fin heat exchanger 1 caused by acting force of the air guide part 202 on the fin heat exchanger 1 can be effectively avoided, and the purpose of protecting the fin heat exchanger 1 is achieved; further, since the air guide 202 does not contact the fin heat exchanger 1, the air guide 202 does not affect the air output of the fin heat exchanger 1 even if the air guide is partially opposed to the air output side of the fin heat exchanger 1.

It should be noted that, considering the structural strength problem of the end plate 3, the first plate body 301 and the fin heat exchanger 1 are ensured to be effectively connected, the second plate body 302 and the air guiding portion 202 are abutted and cannot deform, the first plate body 301 and the second plate body 302 are designed into an integrated structure, and the structural strength of the end plate 3 is ensured to meet the installation requirement.

As a specific implementation manner of this embodiment, a positioning hole or a positioning groove is formed on one side of the second plate body 302 opposite to the air guiding portion 202, a protruding positioning portion that is positioned in a matching manner with the positioning hole or the positioning groove is formed on one side of the air guiding portion 202 opposite to the second plate body 302, and through the matching positioning of the positioning hole or the positioning groove and the positioning portion, the second plate body 302 and the air guiding portion 202 can be accurately positioned and butted, and the positioning structure between other components can be matched and installed, so that the connection accuracy between the components is further improved. Meanwhile, in order to further improve the sealing property when the second plate 302 and the air guide 202 are in contact, a seal ring may be provided at the contact. In addition, in order to ensure the sealing performance of the positioning of the air guide part 202 and the end plate 3, an air volume sensor can be arranged at one end, far away from the fin heat exchanger 1, of the second plate body 302 to monitor, and whether air leaks from between the second plate body 302 and the air guide part 202 or not is detected in real time through the air volume sensor, so that the effect of accurate sealing is achieved.

After entering the air inlet cavity, the wind firstly collides with the wind guiding surface 205 of the wind guiding part 202, and in order to avoid the condition of frontal collision, the wind guiding surface 205 is specially designed to be inclined, so that the wind has a buffering and guiding function when striking, the wind can flow along the wind guiding surface 205, and the noise generated by the collision of the wind and the inclined plane is small. At the same time, the corner of the opposite side of the wind guiding part 202 is rounded, and the inclined wind guiding surface 205 is matched to guide the wind flow direction more effectively to reduce noise.

If the air outlet direction of the heat pump unit needs to be adjusted, if a front air outlet mode and a rear air outlet mode are realized, an air outlet is not formed in the cover plate 8, and a corresponding air outlet is formed in the front panel 7.

It should be noted that the plurality of air outlets are formed in the cover plate 8 and are uniformly distributed at intervals, and in order to improve the structural strength of the air outlets in the cover plate 8, reinforcing ribs can be additionally arranged on each air outlet.
