Embodiment Construction

[0019] Taking the straight all-aluminum microchannel heat exchanger as an example, the specific implementation method is as follows:

[0020] Such as Figure 1-3 As shown, a fan port plate 6 is set above the body 1, a fan motor 3, a fan blade 4 and a fan support 5 are arranged on the fan port plate 6, and a shroud 7 is arranged below the fan port plate 6, and the direction of the shroud 7 is downward. A flow equalizing cover 8 is arranged outside the motor, and the direction of the flow equalizing cover 8 is upward, and a filter screen 9 is arranged above the flow equalizing cover 8, and the filter screen can be easily disassembled to form a ventilation system under the blower fan.

[0021] Such as Figure 4-7 As shown: an all-aluminum micro-channel heat exchanger 2 is set on the upper part of the body 1; the cross-section of the micro-channel 2-7 in the all-aluminum micro-channel heat exchanger 2 is a diamond-shaped structure for parallel flow inside the all-aluminum micro-c...

Abstract

The invention discloses an air-cooled heat pump unit, belonging to the technical field central air conditioners. A fan port plate is arranged above a machine body of the unit and is provided with a fan motor, fan blades and a fan bracket, a flow guide cover is arranged below the fan port plate, a detachable filter screen is arranged above a flow equalization cover, and thus a fan downward air outlet ventilation system is constituted; the machine body is provided with an all-aluminum micro-channel heat exchanger; the section of a micro-channel in a porous aluminum flat pipe for parallel flows inside the all-aluminum micro-channel heat exchanger has a parallelogram structure; a header is provided with an air collecting hole; aluminum foils are obliquely and symmetrically arranged at the upper and the lower ends of the porous aluminum flat pipe for the parallel flows; headers are symmetrically arranged at the left and the right ends of the all-aluminum micro-channel heat exchanger, and are provided with installation brackets; and one side of each header is provided with an air pipe, and the other side of each header is provided with a liquid pipe, so that the all-aluminum micro-channel heat exchanger is constituted. By adopting the air-cooled heat pump unit, the contact area and heat exchange area between the aluminum foil and the porous aluminum flat pipe for the parallel flows are increased, the air exhaust mode of the air-cooled heat pump unit is changed into downward air exhaust, condensed water is blown out easily when an all-aluminum micro-channel is used for defrosting during heating in winter, and freezing is prevented from influencing the heating effect.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning, and in particular relates to an air-conditioning unit. Background technique [0002] The fan of the commercial air-conditioning system is arranged on the lower side of the fan port plate. In the all-aluminum microchannel heat exchanger, the porous aluminum flat tube for parallel flow is placed vertically with the folded aluminum foil section, and the porous aluminum flat tube header for parallel flow is welded. When the porous aluminum flat tube for parallel flow is placed obliquely, the contact area between the aluminum foil and the porous aluminum flat tube for parallel flow is small, which affects the heat transfer effect. And it is only suitable for single-cooling units, the defrosting effect is extremely poor, and the heat exchange effect in winter is low, which limits the application of all-aluminum micro-channel all-aluminum micro-channel heat exchangers in heat pump units...
