Description

Technical Field

[0001] This utility model relates to the field of HVAC equipment technology, specifically to a reactor protection structure and a heat pump. Background Technology

[0002] The reactor in a heat pump generates heat during operation. In existing technologies, ventilation holes are required in the reactor housing to dissipate heat. Patent document CN210463313U discloses an outdoor unit and air conditioner. Its disclosed structure includes a reactor housing and a cover. The reactor housing has a fixing part and ventilation holes, which allow heat dissipation for the first reactor housed within the housing. The cover has a waterproof part to block condensation splashed onto the ventilation holes. However, this waterproof part only blocks condensation splashing from the side onto the reactor housing and cannot effectively block water droplets splashing from below. Utility Model Content

[0003] This utility model provides a reactor protection structure and a heat pump to solve the problem that the existing heat pump protection structure for reactors cannot provide comprehensive protection for the reactor while ensuring ventilation.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A reactor protection structure is installed on a partition inside a heat pump to protect the reactor inside the heat pump. The reactor protection structure includes a reactor box and a protective shell. The reactor box includes a box body and a box cover.

[0006] The box is fixedly mounted on the partition by a support frame, and the box is close to the top of the partition, with a gap between the box and the partition. The box is used to house the reactor. The side of the box away from the partition is an open surface. A box cover is installed on the open surface of the box to close the reactor box.

[0007] A first ventilation hole group is provided on the partition plate at the position corresponding to the installation position of the box body, a second ventilation hole group is provided on the side of the box body near the partition plate, and a third ventilation hole group and a fourth ventilation hole group are provided on the two sides of the box body perpendicular to the surface of the partition plate, respectively.

[0008] The protective shell is fixedly installed on the partition. The top surface and the side facing the partition of the protective shell are open surfaces. The protective shell covers the reactor box inside.

[0009] The bottom of the protective shell is equipped with a fifth set of ventilation holes;

[0010] Water droplets splashing towards the sides of the protective shell are blocked by the shell, while water droplets splashing towards the bottom of the shell are blocked by the bottom surface of the box. This ensures that the reactor protection structure can prevent water droplets inside the heat pump from splashing onto the reactor while maintaining ventilation, thus protecting the reactor.

[0011] In one embodiment, the first and second ventilation hole groups are staggered in the height direction, so that water droplets cannot splash from the partition side into the reactor box.

[0012] In one embodiment, the third and fourth ventilation hole groups on both sides of the box are staggered in the height direction, which improves the ventilation effect inside the reactor box.

[0013] In one embodiment, each side of the protective shell is inclined, so that the cross-sectional area of ​​the protective shell gradually increases from bottom to top, which facilitates the dripping of liquid droplets collected on the protective shell.

[0014] A heat pump includes a partition and a reactor. The partition is equipped with the aforementioned reactor protection structure. The reactor protection structure ensures ventilation inside the reactor box while preventing water droplets inside the heat pump from splashing onto the reactor, thus protecting the reactor.

[0015] The beneficial effects of this utility model are as follows:

[0016] The reactor protection structure provided by this utility model not only ensures ventilation and heat dissipation of the reactor, but also protects the reactor from water droplets splashed from inside the heat pump, thus providing more comprehensive protection for the reactor.

[0023] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0024] like Figure 1-2 As shown, this embodiment of the present invention provides a reactor protection structure, which is installed on a partition 1 inside a heat pump. The reactor protection structure includes a reactor box 2 for accommodating and protecting the reactor 3 and a protective shell 5. The reactor box 2 includes a box body 21 and a box cover 22. The box body 21 is fixedly installed on the partition 1 by a support frame 4, and the box body 21 is close to the top of the partition 1. A gap is formed between the box body 21 and the partition 1 (to ensure ventilation, the gap width between the box body 21 and the partition 1 is greater than 0.5mm). The box body 21 is used to accommodate the reactor 3. The side of the box body 21 away from the partition 1 is an open surface. The box cover 22 is further installed on this open surface to achieve closure, thereby protecting the reactor 3 and preventing water droplets from splashing into the reactor box 2.

[0025] To ensure ventilation, a first ventilation hole group 11 containing multiple evenly distributed ventilation holes is provided on the partition 1 at a position corresponding to the installation position of the box 21. A second ventilation hole group 211 containing multiple evenly distributed ventilation holes is provided on the side of the box 21 near the partition 1. A third ventilation hole group 212 and a fourth ventilation hole group 213 are respectively provided on the two sides of the box 21 perpendicular to the surface of the partition 1. Both the third ventilation hole group 212 and the fourth ventilation hole group 213 contain multiple evenly distributed ventilation holes.

[0026] When the box 21 is installed on the partition 1, the air inside the heat pump enters the box 21 through the first ventilation hole group 11 on the partition 1 and the second ventilation hole group 211 on the box 21 in sequence, and then flows out from the third ventilation hole group 212 and the fourth ventilation hole group 213 on both sides of the box 21, thereby achieving the cooling of the reactor 3 inside the box 21.

[0027] The protective shell 5 is fixedly installed on the partition 1. The top surface and the side facing the partition 1 of the protective shell 5 are open surfaces, covering the reactor box 2 inside. The bottom of the protective shell 5 is provided with a fifth ventilation hole group 51 containing multiple evenly distributed ventilation holes.

[0028] Obviously, part of the air flowing in from the partition 21 flows downward from the fifth ventilation hole group 51 on the protective shell 5, and the other part enters the box 21 from the second ventilation hole group 211 on the box body 21, then flows out from the third ventilation hole group 212 and the fourth ventilation hole group 213, and further flows out from the fifth ventilation hole group 51 from the protective shell 5. Water droplets splashed towards both sides of the protective shell 5 will be directly blocked by the protective shell 5. Since the plane where the fifth ventilation hole group 51 is located is perpendicular to the plane where the second ventilation hole group 211, the third ventilation hole group 212 and the fourth ventilation hole group 213 are located, even if water droplets splashed towards the bottom of the protective shell 5 can pass through the fifth ventilation hole group 51, they will be blocked by the bottom surface of the box body 21. Thus, the reactor protection structure of this utility model can prevent water droplets in the heat pump from splashing onto the reactor 3 while ensuring ventilation, thereby protecting the reactor 3.

[0029] To further prevent water droplets from sequentially passing through the first ventilation hole group 11 and the second ventilation hole group 211 into the housing 21 and splashing onto the reactor, in an improved embodiment of this utility model, the first ventilation hole group 11 and the second ventilation hole group 211 are staggered in the height direction; in a specific embodiment, the first ventilation hole group 11 is close to the top of the housing 21, and the second ventilation hole group 211 is close to the bottom of the housing 21.

[0030] In order to improve the ventilation effect inside the reactor box 2, in an improved embodiment of the present invention, the third ventilation hole group 212 and the fourth ventilation hole group 213 on both sides of the box body 21 are staggered in the height direction. In a specific embodiment, the third ventilation hole group 212 is close to the top of the box body 21, and the fourth ventilation hole group 213 is close to the bottom of the box body 21.

[0031] To further enhance the protective effect of the protective shell 5, in an improved embodiment of this utility model, each side of the protective shell 5 (both sides and the side opposite to the partition 1) is inclined, so that the cross-sectional area of ​​the protective shell 5 gradually increases from bottom to top, which is conducive to the collection and dripping of liquid droplets splashed on the protective shell 5.

[0032] Obviously, this utility model also provides a heat pump, in which the aforementioned reactor protection structure is installed on the partition 1 inside the heat pump.

[0033] The reactor protection structure provided by this utility model ensures the ventilation and heat dissipation of the reactor while protecting it from the impact of water droplets splashed from inside the heat pump.

[0034] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
