Detailed Description

As shown in fig. 1 and 2, a pre-heater structure of a clean air conditioning unit includes a top plate 110, a bottom plate 120, a front plate 130, a rear plate 140, a plurality of condensation pipes 150 capable of guiding air downward, an upper cover 160, and a lower cover 170.

The top plate 110 and the bottom plate 120 are disposed up and down, a front plate 130, a rear plate 140, a left plate 180 and a right plate 190 are disposed between the top plate and the bottom plate, and the front plate 130 and the rear plate 140 respectively form an air inlet and an air outlet.

In one embodiment, the top plate 110 and the bottom plate 120 are arranged horizontally and in parallel.

The top plate 110 has a plurality of first through holes 111 arranged in the left-right direction and in the up-down direction, and the bottom plate 120 has a plurality of second through holes 121 vertically corresponding to the plurality of first through holes 111.

In one embodiment, the first through hole 111 and the second through hole 121 are both vertical through holes, and the first through hole 111 is concentric with the corresponding second through hole 121.

The upper ends of the plurality of condensation pipes 150 are connected to the corresponding first through holes 111, respectively, and the lower ends of the plurality of condensation pipes 150 are connected to the corresponding second through holes 121, respectively.

In one embodiment, the condenser tube 150 is a vertical tube, and in winter in northern areas, the air temperature is at least 20 ℃ below zero, so that the phenomenon that the long steam inlet stroke easily causes steam to be condensed into ice in the steam inlet process, and the pipeline is frozen and burst can be avoided.

The adjacent spaces between the plurality of condensation pipes 150 are equal and blocked between the air inlet and the air outlet, so that the passing air can be uniformly preheated.

Preferably, the condensing tube 150 has fins 151 thereon, which increases the heat conducting area of the condensing tube 150, so that the preheating effect of the preheater is better.

The upper cover 160 is fixed to the top plate 110 to cover the first through holes 111 therein, a partition 161 is provided in the upper cover to vertically partition the interior thereof into an upper chamber and a lower chamber, the partition 161 has a gap with the left or right side of the upper cover 160 to communicate the upper chamber with the lower chamber, and the upper cover 160 has a steam inlet 162 communicating with the upper chamber, so that the entering steam can be distributed into the condensing tubes 150 at the same temperature in the lower chamber, and the effect of uniformly preheating the passing air is also achieved.

The lower cover 170 is fixed to the bottom plate 120 to cover the plurality of second through holes 121 therein, and the lower cover 170 has a water outlet 171.

The lower cover 170 has a slope 172 therein for guiding the condensed water to the water outlet 171, and the slope 172 is located below the plurality of second through holes 121 and has a lower end connected to the water outlet 171, see fig. 3.

In one embodiment, the steam inlet 162 is located on the left side of the upper housing 160, the water outlet 171 is located on the left side of the lower housing 170, and the partition 161 is spaced from the right side of the upper housing 160, so that the steam travels through the same path from any one of the condenser tubes 150, and the preheating efficiency is the same for each path.

During the use, the steam that comes from steam inlet 162 can get into a plurality of condenser pipes 150 respectively to preheat the air through, because condenser pipe 150 all can be water conservancy diversion downwards, can be with comdenstion water discharge from delivery port 171, so the comdenstion water can not form ponding in the condenser pipe, avoids the comdenstion water to condense into ice in the condenser pipe, leads to the pipeline to freeze and explode.
