DETAILED DESCRIPTION OF THE EMBODIMENTS

It is important to note that the embodiments in the application and the characteristics in the embodiments may be combined under the condition of no conflicts. The invention will be described below with reference to the drawings and in combination with the embodiments in detail.

Referring to FIG. 1 to FIG. 3, a heat exchanger according to an embodiment of the invention comprises a fin 1, a gaseous refrigerant heat exchange pipe 6, a liquid refrigerant heat exchange pipe 7, a gaseous refrigerant heat exchange branch pipe 2 and a liquid refrigerant heat exchange branch pipe 3.

Since the gaseous refrigerant heat exchange branch pipe 2 and the liquid refrigerant heat exchange branch pipe 3 comprise two branch pipes respectively and the two branch pipes are located on two sides of the heat exchanger, during installation of an air conditioner, a pipe exiting direction may be selected randomly without bending the pipes and without routing a long pipe on the back of the whole machine.

Preferably, a gaseous refrigerant heat exchange branch pipe channel 4 and a liquid refrigerant heat exchange branch pipe channel 5 are provided on the fin 1 of the heat exchanger according to the embodiment of the invention, the gaseous refrigerant heat exchange branch pipe 2 runs through the gaseous refrigerant heat exchange branch pipe channel 4, and the liquid refrigerant heat exchange branch pipe 3 runs through the liquid refrigerant heat exchange branch pipe channel 5.

By means of the gas pipe connecting device, during installation of the air conditioner, no matter whether a user chooses to perform pipe exiting from the first side or second side of the heat exchanger, the gaseous refrigerant heat exchange branch pipe 2 may be communicated with the gaseous refrigerant heat exchange pipe 6 by means of the gas pipe connecting device. The three-way gas collecting joint 23 and the threaded connection mode are adopted, and the gas pipe connecting device is connected to the gaseous refrigerant heat exchange pipe 6 and the first gaseous refrigerant heat exchange branch pipe 21, which are located on the same side, installation and disassembly may be facilitated. Certainly, the above-mentioned aim may be achieved by means of other connecting devices and connecting modes.

Preferably, a liquid pipe connecting device is provided on the liquid refrigerant heat exchange branch pipe 3, the liquid pipe connecting device in the embodiments of the invention is a three-way liquid inlet joint 33, the first liquid refrigerant heat exchange branch pipe 31 and the liquid refrigerant heat exchange pipe 7 are located on the right side of the heat exchanger, and the three-way liquid inlet joint 33 is connected to the first liquid refrigerant heat exchange branch pipe 31 and the liquid refrigerant heat exchange pipe 7 through threads. By means of the liquid pipe connecting device, during installation of an air conditioner, no matter whether the user chooses to perform pipe exiting from the first side or second side of the heat exchanger, the liquid refrigerant heat exchange branch pipe 3 may be communicated with the liquid refrigerant heat exchange pipe 7 by means of the liquid pipe connecting device. The three-way liquid inlet joint 33 and the threaded connection mode are adopted, and the liquid pipe connecting device is connected to the liquid refrigerant heat exchange pipe 7 and the first liquid refrigerant heat exchange branch pipe 31, which are located on the same side, installation and disassembly may be facilitated. Certainly, the above-mentioned aim may be achieved by means of other connecting devices and connecting modes.

In the embodiments of the invention, the opening and closing device provided at the pipe opening of each branch pipe is a plug, which comprises a first gaseous refrigerant heat exchange branch pipe plug 24 provided at the pipe opening of the first gaseous refrigerant heat exchange branch pipe 21, a second gaseous refrigerant heat exchange branch pipe plug 25 provided at the pipe opening of the second gaseous refrigerant heat exchange branch pipe 22, a first liquid refrigerant heat exchange branch pipe plug 34 provided at the pipe opening of the first liquid refrigerant heat exchange branch pipe 31, and a second liquid refrigerant heat exchange branch pipe plug 35 provided at the pipe opening of the second liquid refrigerant heat exchange branch pipe 32. During installation of the air conditioner, when the user chooses to perform pipe existing from the first side, the first gaseous refrigerant heat exchange branch pipe plug 24 and the first liquid refrigerant heat exchange branch pipe plug 34 may be disassembled to be connected to a user pipe, and the second gaseous refrigerant heat exchange branch pipe plug 25 and the second liquid refrigerant heat exchange branch pipe plug 35 are configured to close the second gaseous refrigerant heat exchange branch pipe 22 and the second liquid refrigerant heat exchange branch pipe 32. Similarly, when the user chooses to perform pipe existing from the second side, the second gaseous refrigerant heat exchange branch pipe plug 25 and the second liquid refrigerant heat exchange branch pipe plug 35 may be disassembled, and the first gaseous refrigerant heat exchange branch pipe plug 24 and the first liquid refrigerant heat exchange branch pipe plug 34 are configured to close the first gaseous refrigerant heat exchange branch pipe 21 and the first liquid refrigerant heat exchange branch pipe 31.

According to another aspect of the invention, an air conditioner is provided, which comprises the above-mentioned heat exchanger, wherein the heat exchanger may be an evaporator or a condenser.

By means of the heat exchanger and the air conditioner in the invention, since the gaseous refrigerant heat exchange branch pipe 2 and the liquid refrigerant heat exchange branch pipe 3 comprise two branch pipes respectively and the two branch pipes are located on two sides of the heat exchanger, during after-sales installation, an appropriate pipe exiting direction is selected according to an actual user indoor structure, a pipe on the left side or right side of the air conditioner is directly connected, and a pipe opening of the pipe does not need to be connected to the other side, so the pipe may be sealed by a plug or a nut. During installation, the pipe does not need to be bended off, and a pipe routing space does not need to be reserved on the back of the whole machine, and the structure is convenient, simple and reliable. Moreover, during design of the air conditioner, a large pipe routing space does not need to be reserved, and the whole machine of the air conditioner may be designed to be thinner and smaller.

When an inner machine needs to be replaced or a pipe routing direction is replaced, a traditional pipe routing mode refers to that: since a joint is probably hidden in the back of the inner machine, the inner machine needs to be disassembled from a wall and then a connecting nut is disassembled. When the pipe routing direction is replaced, the pipe needs to be folded for 180 degrees. These modes are likely to damage the pipe, thereby causing leakage of a coolant, and influencing normal use of the air conditioner. By means of the heat exchanger and the air conditioner provided by the embodiments of the invention, when the inner machine or the pipe routing direction is replaced, a threaded connection between the air conditioner and the pipe is directly removed, so the inner machine may be removed, and then the inner machine or the pipe existing direction of the pipe may be replaced. The simple and convenient effect is achieved. In the whole disassembly process, parts of the pipe are not stressed, thereby preventing from being damaged.

The above is only the preferred embodiments of the invention, and not intended to limit the invention. There may be various modifications and variations in the invention for those skilled in the art. Any modifications, equivalent replacements, improvements and the like made within the spirit and principle of the invention shall fall within the scope of protection of the invention.
