Description

A double-wall cabinet air handling unit

technical field

The utility model relates to the technical field of air conditioning units, in particular to a double-wall cabinet type air handling unit. the

Background technique

Double-wall cabinet-type air handling unit has the characteristics of large air volume, low noise and stable and reliable performance. It is widely used in hotels, office buildings, hospitals, commercial and residential, scientific research institutions, etc. The structure of the double-walled cabinet type air handling unit in traditional technology generally includes a shell, heat exchanger, fan, motor, etc. The heat exchanger, fan, etc. are all installed in the shell, and the motor and fan are respectively installed on the frame inside the shell. , The heat exchanger is vertically installed in the shell, and the junction of the cabinet door is provided with an insulation layer. The disadvantage of this traditional structure is that, first, the fan and the motor are installed separately, each of which will occupy a certain space, and it is necessary to leave enough space in the housing to install the fan and the motor, which will increase the volume of the entire unit; second, The heat exchanger adopts the method of vertical installation, front or back air inlet in the middle, and air outlet from the top. In order to obtain sufficient air inlet distance, the entire shell can only be made very thick, which increases the volume and increases the cost. ; The 3rd, only PE insulating layer is set at the joint of cabinet door, and its sealing effect is not good enough. the

Utility model content

The technical problem to be solved by the utility model is to provide a double-wall cabinet type air handling unit with small occupation space, good sealing performance and good air intake performance. the

That is to say, the fan and the motor are made into an integrated structure; the heat exchanger is installed obliquely inside the shell; a sealing strip is provided between the insulation layer and the cabinet door, and the sealing strip is closely attached to the cabinet door and the insulation layer respectively . the

Further, the heat exchanger is installed in the housing in an inclined state with its upper part close to the front of the housing and its lower part close to the back of the housing. the

Furthermore, the air inlet of the unit is arranged at the bottom of the casing, and the air outlet of the fan is arranged at the top of the casing. This structure allows the wind to enter from the bottom of the housing and exit from the top. the

The utility model can greatly save space by installing the motor in the fan, which not only saves cost, but also facilitates installation; the heat exchanger is placed obliquely, the air is taken in from the bottom, and the air is discharged from the top, so that the space can be saved, and the unit It is made into an ultra-thin structure, which is not only convenient for installation and cost saving, but also allows the wind to enter the shell well; by setting a sealing rubber strip between the cabinet door and the insulation layer, the sealing effect of the unit is good. the
