An embodiment of the present application provides a heat pump outdoor unit, which includes an outdoor fan 10 and an electronic control box 20, with reference to fig. 1 to 6.

The electronic control box 20 comprises a box body 21 with an air inlet 21a and an air outlet 21b, and an airflow circulation path is formed between the air inlet 21a and the air outlet 21b; the electronic control box 20 is disposed at one side of the outdoor fan 10 so that a part of the airflow generated by the outdoor fan 10 can flow along the airflow path.

Another embodiment of the present application provides a heat pump apparatus including the outdoor unit of any one of the embodiments of the present application.

Specifically, the heat pump device according to the embodiment of the present application refers to any heat pump device having an external heat pump unit, for example, the heat pump device may be a heat pump air conditioner, a heat pump water heater, or the like.

An electric control component is arranged in the box body 21 of the electric control box 20.

The air flow path formed between the inlet port 21a and the outlet port 21b means that the air flow can flow into the case 21 from the inlet port 21a and then flow out from the outlet port 21 b.

The fact that part of the airflow generated by the outdoor fan 10 can flow along the airflow path means that part of the airflow generated when the outdoor fan 10 operates can flow into the box body 21 from the air inlet 21a, and flow out from the air outlet 21b after absorbing heat generated by the electronic control component in the box body 21.

That is to say, the air inlet 21a and the air outlet 21b are disposed on the box body 21 of the electronic control box 20, and a part of air flow generated by the outdoor fan 10 during operation flows into the box body 21 through the air inlet 21a and then flows out from the air outlet 21b, that is, the part of air flow generated by the outdoor fan 10 during operation is introduced into the box body 21 for heat dissipation, rather than heat dissipation through heat dissipation holes, and the air flow introduced into the box body 21 increases the flow rate of the air flow inside the box body 21, so that the heat inside the box body 21 can be rapidly taken out from the air outlet 21b by the air flow, thereby improving the heat dissipation effect of the electronic control box 20.

In an embodiment, referring to fig. 5 and fig. 6, a bent flow channel 21d having an air inlet 21a and a main chamber 21c having an air outlet 21b are formed in the box body 21, and the bent flow channel 21d is communicated with the main chamber 21c, that is, the airflow path passes through the bent flow channel 21d and the main chamber 21c.

Specifically, the electronic control component is mainly disposed in the main chamber 21c.

The bent flow channel 21d is a flow channel having a certain bend, rather than being linear, and the airflow entering the bent flow channel 21d from the air inlet 21a changes the flow direction at the bent portion of the bent flow channel 21d and then flows into the main chamber 21c.

The bent flow passage 21d and the air outlet 21b can be directly communicated with the main chamber 21c, which means that the air flow entering the bent flow passage 21d directly flows into the main chamber 21c, and the air flow flowing into the main chamber 21c directly flows out from the air outlet 21 b. For example, a flow channel for communicating the bent flow channel 21d with the main chamber 21c may be disposed between the bent flow channel 21d and the main chamber 21c, a flow channel having the air outlet 21b may be disposed downstream of the main chamber 21c in the airflow flowing direction, the airflow entering the bent flow channel 21d enters the main chamber 21c through the flow channel between the bent flow channel 21d and the main chamber 21c, and the airflow flowing into the main chamber 21c flows into the flow channel located downstream of the main chamber 21c in the airflow flowing direction and then flows out from the air outlet 21 b. One of the bent flow passage 21d and the air outlet 21b may be directly communicated with the main chamber 21c, and the other one may be indirectly communicated with the main chamber 21c.

Because the water flows such as rainwater in the external environment can flow into the heat pump external machine, the bent flow channel 21d is arranged, so that the water flow entering the box body 21 from the air inlet 21a can be blocked to a certain extent, and the water flow such as rainwater can be well prevented from being thrown into the main chamber 21c from the air inlet 21a under the action of the outdoor fan 10.

In addition, referring to fig. 5 and 6, no matter whether the bent flow channel 21d is provided or not, the air outlet 21b is provided on the bottom wall of the box body 21, so that water flows such as rainwater can be prevented from flowing into the box body 21.

As an example, referring to fig. 5 and 6, the box body 21 has a main chamber 21c, and a partial area of a side wall of the main chamber 21c protrudes outward, so that a sub-chamber communicating with the main chamber 21c and having an air inlet 21a is formed in the box body 21, that is, the sub-chamber is only a relatively small space compared with the main chamber 21c.

With continued reference to fig. 5 and 6, the electrical control box 20 includes a barrier 22 disposed at the communication between the main chamber 21c and the sub-chamber, and a partial region of the barrier 22 extends into the sub-chamber to define a bent flow passage 21d in the sub-chamber. That is, the bent flow path 21d may be partitioned and formed in the sub-chamber by providing the barrier 22. The blocking member 22 may be fixed in the box 21 by welding or the like, or may be integrally formed with the box 21.

In a specific embodiment, referring to fig. 5 and fig. 6, the top side of the blocking member 22 is folded toward the side where the sub-chamber is located to form a rib 22a, the rib 22a and the side wall of the sub-chamber facing the main chamber 21c are arranged at an interval, which is equivalent to that the interval between the rib 22a and the side wall of the sub-chamber facing the main chamber 21c is the bending position of the bending flow channel 21d. The air inlet 21a is disposed on the bottom wall of the sub-chamber and faces the rib 22a, that is, the rib 22a can provide a certain blocking effect for the water flow entering the box body 21 from the air inlet 21 a.

Referring to fig. 5 and 6, the rib 22a may be inclined downward from a side close to the main chamber 21c to a side away from the main chamber 21c, and when the airflow flowing into the bent flow channel 21d bypasses the bent portion of the bent flow channel 21d, the airflow may flow toward the main chamber 21c under the guidance of the rib 22a, which is equivalent to that the rib 22a may guide the airflow so that the airflow may be quickly introduced into the main chamber 21c.

Referring to fig. 5 and 6, in order to make the rib 22a have a better water retaining effect, the relative positions of the rib 22a and the air inlet 21a may be: on a projection plane parallel to the bottom wall of the sub-chamber, a projection of the air inlet 21a is located within a projection area of the rib 22 a. That is, the rib 22a may completely block the air inlet 21a to prevent water from flowing into the side of the rib 22a away from the air inlet 21a as much as possible.

Referring to fig. 6, preferably, a distance L1 between a projected edge of the rib 22a away from the main chamber 21c and a projected edge of the air inlet 21a away from the main chamber 21c may be greater than or equal to 1.5mm, for example, a distance L1 between a projected edge of the rib 22a away from the main chamber 21c and a projected edge of the air inlet 21a away from the main chamber 21c may be 2mm to 3mm.

In addition, referring to fig. 6, a distance L2 between an outer surface of the side wall of the sub-chamber facing the main chamber 21c and the air inlet 21a may be greater than or equal to 8mm, and this dimension may also better prevent water from flowing into a side of the rib 22a away from the air inlet 21 a.

Referring to fig. 6, the width L3 of the rib 22a may also be greater than or equal to 8mm to achieve a better water retaining effect.

The sealing connection between the box 21 and the partition 40 is to prevent the water in the blower chamber 30a from flowing into the press chamber 30b from the connection between the box 21 and the partition 40 as much as possible.

In order to facilitate installation of the box body 21, in an embodiment, referring to fig. 2, a limiting portion 21e may be disposed on an outer surface of the box body 21, and the limiting portion 21e may be abutted to the partition plate 40 to limit the box body 21, so as to improve the installation efficiency.

Further, in an embodiment, referring to fig. 1 and fig. 2, the electronic control box 20 includes a fixing bracket 23 disposed in the pressing chamber 30b and outside the box body 21, that is, the fixing bracket 23 is disposed in the pressing chamber 30b and outside the box body 21, and the fixing bracket 23 may be connected to only the box body 21 or to both the box body 21 and the partition 40.

With continued reference to fig. 1 and 2, the electronic control box 20 includes a press capacitor 24, the press capacitor 24 is a capacitor matched with the compressor 50, and the press capacitor 24 is connected to the fixing bracket 23, that is, the press capacitor 24 may be disposed outside the box body 21.

Similarly, with continuing reference to fig. 1 and fig. 2, the electronic control box 20 includes a fan capacitor 25, the fan capacitor 25 is a capacitor matched with the outdoor fan 10, the fan capacitor 25 may also be connected to the fixing bracket 23, that is, the fan capacitor 25 may also be disposed outside the box body 21.

The fixing bracket 23 may have various structures, and for example, referring to fig. 1 and fig. 2, the fixing bracket 23 is a fixing plate having an inclined section 23a inclined upward from a side close to the partition 40 toward a side away from the partition 40, a top side of the inclined section 23a is bent to form a connecting section 23b, the connecting section 23b is connected to the box body 21, and the press capacitor 24 is connected to the inclined section 23 a.

Specifically, referring to fig. 1 and 2, the pressing capacitor 24 is generally substantially cylindrical, and therefore, the inclined section 23a for fixing the pressing capacitor 24 is disposed on the fixing plate, so as to save the installation space of the pressing capacitor 24.

In addition, the top side of the inclined section 23a is bent to form the connecting section 23b, so that the inclined section 23a and the connecting section 23b can be smoothly transited, thereby facilitating the routing of the electrical control box 20 and effectively reducing the risk of cutting the fixed plate.

Further, the bottom side of the inclined section 23a may be further provided with an extension section extending vertically, and the fan capacitor 25 may be fixed on the extension section.
