The left-right direction is perpendicular to the up-down direction, that is, a straight line extending in the left-right direction is at right angles to a straight line extending in the up-down direction.

Wherein the front-back direction is perpendicular to the up-down direction and the left-right direction, i.e. the front-back direction is perpendicular to the up-down direction and the front-back direction is perpendicular to the left-right direction, then a straight line extending in the front-back direction is at right angles to a straight line extending in the up-down direction and a straight line extending in the front-back direction is at right angles to a straight line extending in the left-right direction.

As shown in fig. 1 and 2, the heat exchanger 100 further includes an air exhausting member 3, the air exhausting member 3 is disposed in the casing 1, the air exhausting member 3 operates to drive the air in the casing 1 to flow so as to generate a negative pressure at the front air inlet 101, the air exhausting member 3 and the first heat exchanging member 2 are disposed at an interval in the left-right direction, that is, on a plane parallel to the left-right direction, an orthographic projection of the air exhausting member 3 and an orthographic projection of the first heat exchanging member 2 do not overlap, that is, an orthographic projection interval of the air exhausting member 3 is located on the left side or the right side of the orthographic projection of the first heat exchanging member 2, thereby facilitating the thickness reduction of the heat exchanger 100 in the front-back direction and more effectively utilizing regions on both sides of the first heat exchanging member 2. The air exhausting member 3 is located on the side of the first heat exchanging member 2 close to the forced air outlet 103, so that the air exhausting member 3 can be arranged corresponding to the forced air outlet 103, and the air in the casing 1 flows to the forced air outlet 103 under the driving action of the air exhausting member 3 and is exhausted through the forced air outlet 103.

Therefore, under the first air outlet mode, the air exhaust component 3 does not work, the noise-free operation of the heat exchange device 100 is realized, and the air and the first heat exchange component 2 can conduct heat through natural convection, so that the air outlet of the heat exchange device 100 is soft, the non-wind feeling of the heat exchange device 100 can be realized, and the air exhaust device is particularly suitable for small-load application scenes such as sleep and the like. It can be understood that, in the above process, the heat exchange device 100 is suitable for refrigeration, and the air is formed into cold air after exchanging heat with the first heat exchange part 2, and the cold air can spontaneously flow downwards and be discharged through the cold air outlet 102, so as to implement refrigeration of the heat exchange device 100.

Therefore, under the second air outlet mode, the air exhaust component 3 can generate a strong forced convection effect, and air and the first heat exchange component 2 transfer heat through forced convection, so that the temperature can be quickly adjusted. In some embodiments, heat exchange device 100 is suitable for refrigeration and can achieve rapid cooling.

From this, according to heat transfer device 100 of the above-mentioned embodiment of this application, through the rational arrangement relative position of advancing air inlet 101, cold wind export 102 and forced air outlet 103 to correspond and set up first heat transfer part 2 and air exhaust part 3, make heat transfer device 100 realize not having the wind sense to go out when air exhaust part 3 does not operate, refrigerate fast when air exhaust part 3 moves, thereby heat transfer device 100 can effectively satisfy the differentiation demand of different periods, has promoted heat transfer device 100's practicality and suitability.

It is understood that in some embodiments, the number of the front air inlets 101 is one or more, the number of the cold air outlets 102 is one or more, and the number of the forced air outlets 103 is one or more.

In some embodiments, as shown in fig. 1, the outer surface 10 of the shell 1 forms an appearance surface of the heat exchange device 100, so as to achieve a regular arrangement of the appearance of the heat exchange device 100.

In some embodiments, as shown in fig. 4 to 6, a distance L1 between the center plane of the first heat exchange member 2 and the inner surface of the front wall a of the housing 1 is smaller than a distance L2 between the center plane of the first heat exchange member 2 and the inner surface of the rear wall B of the housing 1, that is, a distance L1 between the center plane of the first heat exchange member 2 and the inner surface of the front wall a is smaller than a distance L2 between the center plane of the first heat exchange member 2 and the inner surface of the rear wall B in the front-rear direction, the first heat exchange member 2 is disposed closer to the inner surface of the front wall a than to the inner surface of the rear wall B, an upstream communication chamber 111 may be defined between the center plane of the first heat exchange member 2 and the inner surface of the rear wall B, the upstream communication chamber 111 has a larger volume, and when the heat exchange device 100 is used for refrigeration, the upstream communication chamber 111 is used for storing cold air having a density higher than that of the outside air, the cold air is gathered, and accelerated and naturally sinks under the action of gravity.

Here, since the front air inlet 101 penetrates the front wall surface a, a distance L1 between the first heat exchange member 2 and the inner surface of the front wall surface a refers to a distance between the first heat exchange member 2 and a plane where the edge of the front air inlet 101 is located.

For example, in the example of fig. 2, 4 and 9, the front wall a and the rear wall B are arranged in parallel at a distance, the first heat exchanging element 2 is located between the front wall a and the rear wall B, the air flow at the front air inlet 101 can flow into the housing 1 from front to rear through the front wall and the rear wall to exchange heat with the first heat exchanging element 2, since the distance L1 between the center plane of the first heat exchanging element 2 and the inner surface of the front wall a is smaller than the distance L2 between the center plane of the first heat exchanging element 2 and the inner surface of the rear wall B, the upstream communication chamber 111 can be defined between the center plane of the first heat exchanging element 2 and the inner surface of the rear wall B among the inner surfaces of the front wall a and the rear wall B, so that the first heat exchanging element 2 is arranged closer to the front air inlet 101 with respect to the rear wall B, the upstream communication chamber 111 is located downstream of the first heat exchange member 2 in the flow direction of the air flow, and the air flow flows toward the cold air outlet 102 through the upstream communication chamber 111.

When the heat exchange device 100 is used for refrigeration, because the cold air outlet 102 is located below the forward air inlet 101, air after heat exchange with the first heat exchange component 2 is formed into cold air (which can be understood as air with lower temperature), the cold air has low temperature and high density, and can sink spontaneously, because the upstream communication chamber 111 has a larger volume, a large amount of cold air can be gathered conveniently, and a large amount of cold air is driven by the action of gravity, so that spontaneous sinking of cold air is facilitated, for example, the cold air can sink downwards to the cold air outlet 102 and is discharged through the cold air outlet 102, and refrigeration of the heat exchange device 100 is realized; meanwhile, due to the sinking of the cold air in the upstream communicating chamber 111, a low-pressure area is formed at the upper part of the upstream communicating chamber 111, and under the driving of the pressure difference, the hot air (which can be understood as air with higher temperature) outside the casing 1 can continuously flow from the front air inlet 101 into the casing 1 to exchange heat with the first heat exchange component 2, so that the circulation of air flow and cold and heat changes can be realized without the aid of or with the aid of a small amount of active driving devices such as the air exhaust component 3, and the continuous operation of the refrigeration cycle of the heat exchange device 100 is ensured.

In other examples, the first heat exchange member 2 is disposed in contact with the inner surface of the front wall surface B, at this time, the upstream communication chamber 111 is not defined between the first heat exchange member 2 and the inner surface of the front wall surface B, or a minute space between the first heat exchange member 2 and the inner surface of the front wall surface B forms the upstream communication chamber 111, the downstream communication chamber 112 is disposed at the lower side of the first heat exchange member 2, the downstream communication chamber 112 is defined by the inner surface of the front wall surface a and the inner surface of the rear wall surface B, and the downstream communication chamber 112 is communicated with the airflow channel of the first heat exchange member 2, so that the natural sinking effect of the cold air can be ensured as well, and the occupied space of the heat exchange device 100 can be saved.

In some other embodiments of the present application, the front wall a is disposed non-parallel to the rear wall B.

The first heat exchange part 2 includes a first single heat exchange tube bank 28, the first single heat exchange tube bank 28 includes a plurality of first heat exchange tubes 211, and the center lines of the plurality of first heat exchange tubes 211 enclose a first plane 2 a.

The air outlet control method of the heat exchange device 100 according to the third aspect of the present application is described below with reference to the drawings, where the heat exchange device 100 is the heat exchange device 100 according to the first aspect of the present application.

As shown in fig. 36 and 37, the heat exchanger 100 has a first air outlet mode in which the first opening/closing door 7 opens the cool air outlet 102 and the air discharging member 3 does not operate.

For example, in the first air outlet mode, the air in the housing 1 exchanges heat with the first heat exchange component 2, the air after heat exchange flows downward to the cold air outlet 102 and is discharged through the cold air outlet 102, a negative pressure may be formed at the front air inlet 101, and the air outside the housing 1 may flow into the housing 1 through the front air inlet 101 and then exchanges heat with the first heat exchange component 2. From this, under first air-out mode, because exhaust component 3 is out of work, can realize heat transfer device 100 noiselessness operation, and the air can realize heat transfer device 100's soft air-out through natural convection with first heat transfer component 2, realizes heat transfer device 100's no wind sense effect to heat transfer device 100's first air-out mode can be applicable to the light load application scenes such as sleep. It can be understood that, in the process, the heat exchanging device 100 is suitable for refrigeration, and the air is formed into cold air after exchanging heat with the first heat exchanging part 2, and the cold air can spontaneously flow downwards and be discharged through the cold air outlet 102, so as to realize refrigeration of the heat exchanging device 100.

According to the air-out control method of the heat exchange device 100, the control logic is simple and convenient to realize, the non-wind-sensing air-out of the heat exchange device 100 is convenient to realize, and the comfort of a user is improved.

In the first air outlet mode, no airflow basically flows into or out of the housing 1 at the forced air outlet 103, and the normal operation of the heat exchanger 100 is not affected by the state of the second switch door 8 in the first air outlet mode. In some embodiments, in the first air outlet mode, the second switch door 8 closes the forced air outlet 103. In other embodiments, in the first air outlet mode, the second switch door 8 opens the forced air outlet 103.

In some embodiments, as shown in fig. 37, the heat exchanger 100 has a second air outlet mode, in which the first opening/closing door 7 closes the cold air outlet 102, the second opening/closing door 8 opens the forced air outlet 103, and the air exhausting member 3 operates.

For example, in the second air outlet mode, the air exhausting member 3 operates to generate a negative pressure at the front air inlet 101, air outside the casing 1 can flow into the casing 1 through the front air inlet 101 to exchange heat with the first heat exchanging member 2, and since the air exhausting member 3 is located at a side of the first heat exchanging member 2 close to the forced air outlet 103, the air after heat exchange can be exhausted through the forced air outlet 103 under the driving action of the air exhausting member 3. From this, under second air-out mode, air exhaust component 3 can produce stronger compulsory convection effect, and air and first heat transfer component 2 can be through the heat transfer of compulsory convection to realize the quick adjustment of temperature, when heat transfer device 100 is used for the refrigeration, can realize rapid cooling.

Next, a method for controlling outlet air of a heat exchange device 100 according to a fourth aspect of the present application will be described with reference to fig. 38, where the heat exchange device 100 is the heat exchange device 100 according to the first aspect of the present application.

The heat exchanger 100 has a first air-out mode and a second air-out mode, and in the first air-out mode, the control switch switches the air-exhausting component 3 to be out of operation, and in the second air-out mode, the control switch switches the air-exhausting component 3 to be operated. From this, can switch the operating condition of air exhaust part 3 through control switch, can realize the switching of heat transfer device 100 air-out mode, be favorable to realizing heat transfer device 100 air-out mode intelligence and switch.

For example, in the first air outlet mode, the air in the housing 1 exchanges heat with the first heat exchange component 2, the air after heat exchange can flow to the cold air outlet 102 in the up-down direction and be discharged through the cold air outlet 102, a negative pressure can be formed at the front air inlet 101, and the air outside the housing 1 can flow into the housing 1 through the front air inlet 101 and then exchange heat with the first heat exchange component 2. Therefore, under the first air-out mode, because the air exhaust component 3 does not work, the noise-free operation of the heat exchange device 100 can be realized, and the air and the first heat exchange component 2 can transfer heat through natural convection, the non-wind feeling of the heat exchange device 100 is realized, so that the first air-out mode of the heat exchange device 100 can be suitable for small-load application scenes such as sleep and the like.

In the second air outlet mode, the air exhaust component 3 operates to generate negative pressure at the front air inlet 101, air outside the housing 1 can flow into the housing 1 through the front air inlet 101 to exchange heat with the first heat exchange component 2, and because the air exhaust component 3 is located at one side of the first heat exchange component 2 close to the forced air outlet 103, the air after heat exchange can be exhausted through the forced air outlet 103 under the driving action of the air exhaust component 3. From this, under second air-out mode, air exhaust component 3 can produce stronger compulsory convection effect, and air and first heat transfer component 2 can be through the heat transfer of compulsory convection to realize the quick adjustment of temperature, when heat transfer device 100 is used for the refrigeration, can realize rapid cooling.
