Embodiment 1

[0045] Alternative embodiment 1: Slide rails are installed under the heat exchange unit, several rows of heat exchange units can move relatively, the drive mechanism can use a rack and pinion mechanism, the motor drives the active gear, the gear drives the rack, and the rack is connected to a group of evaporation In order to realize the relative movement of the evaporator, the driving mechanism is not limited to the gear mechanism, and the connecting rod mechanism can also be realized.

Embodiment 2

[0046] Alternative embodiment 2: The direction of the overall movement of the heat exchanger changes, including that the position of one row of evaporators is fixed, and the position of the other row of evaporators changes, including that the two rows of evaporators can move relative to each other;

[0047] The present invention also provides an air conditioner, which includes the heat exchanger described in any one of the preceding items.

[0048] The invention provides a relatively movable heat exchanger assembly composed of two sets of heat exchangers parallel to each other, which can match and meet the needs of refrigeration systems in different situations. When high refrigeration capacity is required, the fin spacing of the heat exchanger can be adjusted. To the minimum, the heat exchange capacity is strong. When the cooling capacity is required to be low, adjust the fin spacing of the heat exchanger to the maximum, so that the condensed water on the heat exchanger can be ...

Abstract

The invention provides a heat exchanger and an air conditioner. The heat exchanger includes: more than two rows of heat exchange units (1), each row of heat exchange units (1) includes at least one heat exchange tube (11) and a plurality of heat exchange tubes (11) Fins (12), a plurality of heat exchange fins (12) are sleeved on the heat exchange tube (11); and the two rows of heat exchange units (1) can move mutually so that one heat exchange unit (1) The distance between two adjacent heat exchanging fins (12) in the unit can be adjusted to increase or decrease by shielding the heat exchanging fins (12) in another adjacent heat exchanging unit. The invention can adjust the spacing between the heat exchange fins. When the system requires high refrigeration and high heat exchange, the spacing between the fins can be adjusted to the minimum or smaller. When the system is prone to condensation or dust accumulation, the spacing between the fins can be adjusted. To the maximum or larger, while ensuring the heat exchange capacity can also prevent condensation or dust, which greatly improves the performance of the heat exchanger and the performance of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of evaporative cooling, in particular to a heat exchanger and an air conditioner. Background technique [0002] At present, both the evaporator of the internal unit and the condenser of the external unit have a fixed-spacing structure. The smaller the spacing of the evaporator of the internal unit, the better the heat transfer effect, but the problem of condensation is serious. The larger the heat transfer effect is, the lower the heat transfer effect is, but it is not easy to condense. There is no good solution to this problem at present. A heat exchanger with good heat transfer effect and not easy to condense is needed. The smaller the heat exchange effect, the better, but it is easy to accumulate dust. The larger the distance between the plates, the less dust will accumulate, but the heat exchange effect will decrease. A heat exchanger with good heat exchange effect and less dust accumulation is needed. ...
