Detailed Description

The invention will be described in further detail with reference to the drawings and specific examples.

As shown in fig. 1: a heat exchanger comprises a heat exchanger body 1, wherein a fresh air inlet 11, a fresh air outlet 12, an air exhaust inlet 13 and an air exhaust outlet 14 are arranged on the heat exchanger body 1; a fresh air channel is formed between the fresh air inlet 11 and the fresh air outlet 12, and an exhaust channel is formed between the exhaust air inlet 13 and the exhaust air outlet 14; the heat exchanger body 1 is provided with a blocking part 2 at one surface between the fresh air inlet 11 and the fresh air outlet 12.

The scheme has the following advantages: by arranging the blocking part 2, the fresh air coming out of the heat exchanger body can be blocked from being mixed with the air which is not filtered in the fresh air machine, mixed air is generated, and therefore pollution is caused to the fresh air; and the setting of barrier portion can make the new trend of following the heat exchanger body exhaust be in sealed space, can not contact with the air that is not filtered, guarantees to filter the index and reaches more than 99.9%.

In this embodiment, the blocking portion 2 is disposed at the exhaust outlet of the heat exchanger body 1, and the blocking portion 2 is communicated with the exhaust outlet 14. Because the exhaust outlet 14 is arranged at the side of the fresh air outlet 12, the blocking part 2 is arranged at the position, and the exhausted fresh air can be kept clean. The blocking part 2 and the heat exchanger body 1 can be integrally formed or separately arranged.

In this embodiment, the blocking portion 2 includes a baffle 21 and an air outlet channel 22 extending outward along the baffle, and the air outlet channel 22 is connected to the air outlet 14. By arranging the baffle 21, when the heat exchanger is arranged in the body of the fresh air fan, the baffle 21 can block unfiltered air introduced due to the fact that the heat exchanger cannot be sealed in place in the body, and therefore pollution caused by fresh air is prevented; set up air-out passageway 22 on baffle 21, because stop part 2 has been established in the export position of airing exhaust of heat exchanger body 1, if do not set up the air-out passageway, can cause the jam to airing exhaust, consequently, with air-out passageway 22 and export 14 intercommunication of airing exhaust, can make old wind pass through the heat exchanger body and discharge from the air-out passageway to do not influence airing exhaust.

In the embodiment, the cross section of the heat exchanger body 1 is hexagonal; the fresh air inlet 11 and the fresh air outlet 12 are arranged on two opposite hexagonal inclined planes; the exhaust air inlet 13 and the exhaust air outlet 14 are provided on the other opposite slope of the hexagon. The baffle 21 is connected to the vertical surface between the fresh air outlet 12 and the exhaust air outlet 14, and the baffle 21 covers the vertical surface; the cross section of the air outlet channel 22 is a right triangle, and the inclined plane is just connected with the surface of the air outlet 14 in a shape matching manner. The air outlet channel 22 is designed to be in a right-angled triangle structure, so that the baffle plate 21 and the air outlet channel 22 are vertically arranged, the sealing performance can be improved, and if the air outlet channel is designed to be in an arc shape or other shapes, air leakage is easy to occur or the installation space is increased. In the embodiment, the baffle 21 and the vertical surface of the heat exchanger body 1 are welded or glued to form a whole; the air outlet channel 22 and the air outlet 14 are welded or glued to form a whole.

As shown in fig. 2: the heat exchanger of the embodiment is mainly applied to a fresh air machine, and is arranged in a machine body 3 of the fresh air machine. Preferably, the arrangement structure of each device in the fresh air fan is as follows: the new trend outlet side of heat exchanger body 1 is equipped with high efficiency filter 4, and high efficiency filter 4's air-out side is equipped with new trend fan 5, the vertical setting of heat exchanger body 1, and parallel arrangement side by side with high efficiency filter 4 and new trend fan 5 on the horizontal direction. An exhaust fan 6 is arranged above the heat exchanger body 1. Fresh air inlet 11 of heat exchanger body 1 is equipped with coarse filter 7, and coarse filter 7 place the angle and fresh air inlet 11 is parallel, preferably pastes coarse filter 7 and fresh air inlet 11 and leans on compact structure to reduce the whole volume of organism, the portability is strong. The heat exchanger body 1 is arranged on the support 8, the support 8 is arranged in the machine body 3, and the support 8 isolates the fresh air outlet side of the heat exchanger body 1 from the exhaust inlet 13 to prevent the pollution caused by the fresh air. A fresh air space 9 for fresh air to flow is arranged between the fresh air outlet side of the heat exchanger body 1 and the high-efficiency filter 4, so that the air inlet resistance of the high-efficiency filter can be reduced; the upper part of the fresh air space 9 is sealed by the blocking part 2 of the heat exchanger body. The heat exchanger body 1 of installing in new fan now, certain space is left with the inside directness of the organism itself of new fan on its upper portion, and high efficiency filter 4 passes through between sealing member and the organism 1 sealedly, but if sealed processing does not put in place, still can get into unfiltered air, consequently, this embodiment make full use of this space, set up barrier portion 2 in this space, neither can increase the original size of organism, can also improve the filter effect.

As shown in fig. 3: in this embodiment, the air outlet of the exhaust fan 6 is connected to the old air outlet of the machine body 3 through the gradual change air duct 10. Because the devices of the invention are compactly arranged, the volume of the whole machine is greatly reduced; because the space where the air exhaust fan 6 is located is limited, if the old air is directly exhausted through the air exhaust fan, the limited air exhaust space can cause large wind resistance and wind pressure and small air output. Therefore, the gradual change wind channel 10 is arranged at the air outlet side of the air exhaust fan, the gradual change wind channel is arc-shaped and is communicated with the air exhaust fan, so that old air enters the gradual change wind channel 10 after passing through the air exhaust fan to reduce wind resistance, and the old air is smooth when being exhausted.

The working principle of the embodiment is as follows: outdoor air gets into the organism after, after coarse filter 7 filters, form the new trend and get into heat exchanger body 1, and indoor old wind also gets into heat exchanger body 1, carry out the heat exchange between with the new trend, the new trend after the heat exchange then is discharged from heat exchanger body 1's new trend export 12, get into new trend space 9, because the upper portion of new trend space 9 is through sheltering from of blocking part 2, form a totally enclosed space, make the new trend of heat exchanger body 1 exhaust get into high efficiency filter 4 through new trend space 9 and filter, reach the filtration index more than 99.9%, arrange to indoor through new trend fan 5 again, improve indoor cleanliness factor greatly. And the indoor old air is exhausted from the air outlet channel 22 of the blocking part 2 after passing through the heat exchanger body 1 and is exhausted to the outdoor through the upper exhaust fan 6.
