Description

Refrigeration cycle apparatus and air conditioner Technical Field The present application relates to the field of air conditioning technologies, and in particular, to a refrigeration cycle device and an air conditioner. Background With the continuous development of air conditioning technology, air conditioning occupies an increasingly important position in people's lives. In the actual use process, electronic components on a printed circuit board in the refrigeration cycle equipment of the current air conditioner are easy to damage under the low-temperature condition, so that the refrigeration cycle equipment cannot be used normally, and the use effect of the current refrigeration cycle equipment under the low-temperature condition is poor. Disclosure of Invention The embodiment of the application aims to provide refrigeration cycle equipment and an air conditioner, which solve the problem that the current refrigeration cycle equipment is poor in use effect under a low-temperature condition. In a first aspect, an embodiment of the present application provides a refrigeration cycle apparatus, including a housing, a partition, a printed circuit board, a heater, a heat exchanger, a first fan, and a second fan, where the housing includes a receiving cavity, the partition is disposed in the receiving cavity and divides the receiving cavity into a first cavity portion and a second cavity portion, the heater and the first fan are disposed in the first cavity portion, the printed circuit board and the heat exchanger are disposed in the second cavity portion, and the second fan is at least partially disposed in the second cavity portion. As an alternative embodiment, the housing is a rectangular housing, and the first surface, the first cavity, the second cavity and the second surface are sequentially distributed along a direction from the first surface to the second surface of the rectangular housing, wherein the first surface is a surface facing away from a mounting surface, the second surface is a surface facing toward the mounting surface, and the mounting surface is a surface for mounting the refrigeration cycle device. As an alternative embodiment, a portion of the second fan is located within the second cavity portion and another portion of the second fan is located within the first cavity portion. As an alternative embodiment, the heat exchanger includes a heat radiating plate and a fin disposed on the heat radiating plate. As an alternative embodiment, the number of the fins is plural, and the plural fins are opposite to each other and are arranged on the heat dissipation plate at intervals. As an optional implementation manner, the accommodating cavity is a rectangular accommodating cavity, the first fan is arranged at a position where a first corner of the rectangular accommodating cavity is located, the second fan is arranged at a position where a second corner of the rectangular accommodating cavity is located, and the first corner and the second corner are two corners on a diagonal line of the rectangular accommodating cavity. As an alternative embodiment, the partition plate is provided with a first ventilation hole and a second ventilation hole, the first ventilation hole is opposite to the first fan, and the second ventilation hole is opposite to the second fan. As an alternative embodiment, a temperature sensor is also provided in the second cavity portion. As an alternative embodiment, the number of the first fans and the number of the second fans are all plural. In a second aspect, an embodiment of the present application further provides an air conditioner, including the refrigeration cycle apparatus according to the first aspect. One of the above technical solutions has the following advantages or beneficial effects: In the embodiment of the application, the refrigeration cycle equipment comprises a shell, a baffle plate, a printed circuit board, a heater, a heat exchanger, a first fan and a second fan, wherein the shell comprises a containing cavity, the baffle plate is arranged in the containing cavity and divides the containing cavity into a first cavity part and a second cavity part, the heater and the first fan are arranged in the first cavity part, the printed circuit board and the heat exchanger are arranged in the second cavity part, and the second fan is at least partially arranged in the second cavity part.
