Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidification appliances, and in particular relates to a heat exchange component used in a dehumidifier and a rotary dehumidifier. Background Art

[0002] The principle of the rotary dehumidifier is to physically adsorb the moisture in the air onto a porous synthetic dehumidification disk for dehumidification and then discharge it.

[0003] After the dehumidification disc of the rotary dehumidifier absorbs moisture, the dehumidification disc rotates continuously and switches between moisture absorption and drying reduction. Drying reduction is achieved by blowing hot air to the dehumidification disc, and the high-temperature and high-humidity air then passes through the heat exchange component to condense the moisture in the high-temperature and high-humidity air, thereby regenerating the dehumidification disc. Nowadays, most of the heat exchange components on the market dehumidify the high-temperature and high-humidity air by simply setting a condensing sheet between the air inlet and the air outlet of the heat exchange component to achieve the effect of cooling, condensing and dehumidifying. This cooling effect is average, resulting in the air returning from the air outlet to the dehumidification disc not being dry enough, affecting the regeneration effect of the dehumidification disc, and ultimately affecting the dehumidification effect.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 3As shown, the embodiment of the utility model provides a heat exchange component used in a dehumidifier, including a base 1, an upper seat 2, a refrigeration component and a plurality of heat exchange pipes 3 arranged between the base 1 and the upper seat 2; the base 1 is provided with an air inlet chamber 101 connected to the lower end of part of the heat exchange pipe 3, and an air outlet chamber 102 connected to the lower end of another part of the heat exchange pipe 3, and the base 1 is also provided with an air inlet 11 connected to the air inlet chamber 101 and an air outlet 12 connected to the air outlet chamber 102; the upper seat 2 is provided with a cavity 201 connected to the upper ends of the plurality of heat exchange pipes 3; the heat exchange component of this scheme is used for regenerating the dehumidification wheel of the rotary dehumidifier. When the dehumidification wheel is heated and regenerated, the high-temperature and high-humidity air enters the cavity of the upper seat from the air inlet chamber of the base along the part of the heat exchange pipe, and then enters the air outlet chamber of the base from the cavity along the part of the heat exchange pipe, so that the high-temperature and high-humidity air is cooled and dehumidified through the heat exchange pipe. Furthermore, the refrigeration assembly includes a refrigeration fin 41 disposed on the upper seat 2, a cooling member 42 disposed at the cold end of the refrigeration fin 41 and located in the cavity 201, and a heat sink 43 disposed at the hot end of the refrigeration fin 41 and located outside the upper seat 2. This solution also adds a refrigeration assembly to the upper seat, and uses the cooling fin located in the cavity to achieve effective condensation of the air flowing through the cavity, further improving the condensation effect, so that the humidity of the air when it is guided back from the air outlet to the dehumidification wheel is lower, and the heating regeneration effect of the dehumidification wheel is better.

[0035] Specifically, the embodiment of the utility model is to add a cooling member 42 between the airflow flowing through the upper end of the heat exchange pipe, which is cooled by the cold end of the semiconductor refrigeration sheet, so that the airflow can be further condensed, rather than relying solely on the temperature of the heat exchange pipe itself, thereby greatly increasing the dehumidification effect. Therefore, the cooling member 42 described in this solution is located between the upper air outlet of the air inlet condenser pipe and the upper air inlet of the air outlet condenser pipe; wherein the air inlet condenser pipe is a portion of the heat exchange pipe 3 whose lower end is connected to the air inlet cavity 101 among the multiple heat exchange pipes 3, and the air outlet condenser pipe is a portion of the heat exchange pipe 3 whose lower end is connected to the air outlet cavity 102 among the multiple heat exchange pipes 3.

[0036] In the embodiment of the utility model, the cooling member 42 is a plurality of fins extending downward from the top wall of the cavity 201, and the plurality of cooling members 42 are arranged at intervals. Its simple structure can increase the contact area with the airflow in the cavity, thereby achieving a good condensation and dehumidification effect, and the condensed water will naturally fall back along the heat exchange pipe to the base 1 for collection and discharge.

[0037] In the present embodiment, the cooling plate is arranged in the following manner: Figure 3As shown, the plurality of cooling fins are spaced apart along the length direction of the upper seat 2. This arrangement allows the airflow entering the cavity 201 to contact the cooling fins and be blocked by the cooling fins, thereby allowing the airflow to fully contact the cooling fins and improving the cooling and dehumidification effect.

[0038] In the present embodiment, the cooling plate is arranged in the second embodiment. Figure 5 As shown, the plurality of cooling fins are spaced apart along the width direction of the upper seat 2, that is, a single cooling fin 42 extends along the length direction of the upper seat 2, and the single cooling fin 42 is longer, so that the airflow entering the cavity 201 will flow through the gaps between the cooling fins, thereby making the airflow fully contact with the cooling fins, thereby improving the cooling and dehumidification effect.

[0039] In the embodiment of the utility model, in order to conveniently discharge the condensed water, the base 1 is further provided with a first drain pipe 103 communicating with the air inlet cavity 101 and a second drain pipe 104 communicating with the air outlet cavity 102 .

[0040] In the embodiment of the utility model, a partition 109 is provided inside the base 1, and the partition 109 divides the inner cavity of the base 1 into the air inlet cavity 101 and the air outlet cavity 102. The structure is simple, so that the inflowing air is separated, and the air flowing in through the air inlet cavity 101 flows out through the air inlet condenser tube-the cavity of the upper seat-the air outlet condenser tube-the air outlet cavity of the base in sequence, effectively extending the flow distance of the airflow, thereby improving the dehumidification effect.

[0041] In the embodiment of the utility model, an upper adapter plate 51 and a lower adapter plate 52 are also included; the upper adapter plate 51 is connected to the upper ends of the plurality of heat exchange pipes 3 and is detachably connected to the upper seat 2; the lower adapter plate 52 is connected to the lower ends of the plurality of heat exchange pipes 3 and is detachably connected to the base 1. The upper adapter plate 51 and the lower adapter plate 52 are used to assemble the plurality of heat exchange pipes 3 together, which is convenient for subsequent modular installation and greatly improves installation efficiency.

[0042] like Figure 4As shown, the utility model also provides a rotary dehumidifier, including a body 91, the body 91 is a heat exchange component used in the dehumidifier, and the body 91 is also provided with: a fan component for sucking external air into the body 91; a dehumidification component, which is opposite to the fan component and can rotate relative to the body 91; a regeneration component for introducing hot air into the dehumidification component; the dehumidification component is also provided with a first air outlet and a second air outlet, the first air outlet is opposite to the regeneration component and is connected to the air inlet 11, and the second air outlet is connected to the air outlet 12. The fan component sucks ambient air into the body 91, and the air passes through the dehumidification component so that its moisture is absorbed by the dehumidification component and then guided back to the environment to achieve the dehumidification effect, and the regeneration component is used to generate a hot air flow to blow to the local part of the dehumidification component to take away the moisture of the local part of the dehumidification component, so that the dehumidification component can be recycled and reused, and the air sucked by the fan component can be kept dehumidified. The heat exchange component absorbs the hot air generated by the regeneration component and takes away the moisture, cools the hot air by cooling, and cools and discharges the moisture. Since the rotary dehumidifier adopts the above heat exchange component, it has the same beneficial effect, making the overall dehumidification effect of the dehumidifier better.

[0043] Furthermore, in the embodiment of the utility model, the body 91 is also provided with a heat dissipation channel 911 for accommodating the heat dissipation element 43. This ensures that the refrigeration plate in the heat regeneration component can have a good dehumidification effect. Moreover, one end of the heat dissipation channel 911 is provided with a heat dissipation port connected to the outside, and a heat dissipation fan is arranged at the heat dissipation port.

[0044] The utility model provides a heat exchange component used in a dehumidifier, wherein the high-temperature and high-humidity air enters the cavity of the upper seat from the air inlet cavity of the base along part of the heat exchange pipe, and then enters the air outlet cavity of the base from the cavity along part of the heat exchange pipe. In this way, the high-temperature and high-humidity air is cooled and dehumidified through the heat exchange pipe. In addition, a refrigeration component is added to the upper seat, and the cold guide plate located in the cavity is utilized to realize effective condensation of the air flowing through the cavity, thereby further improving the condensation effect, so that the humidity of the air when it is guided back from the air outlet to the dehumidification wheel is lower, and the heating regeneration effect of the dehumidification wheel is better.
