Abstract

An air conditioner ( 100 ), comprising a compressor ( 110 ), a reversing assembly ( 120 ), an outdoor heat exchanger ( 130 ), an indoor heat exchanger ( 140 ), an electric control heat sink assembly ( 150 ), a first unidirectional throttle valve ( 160 ) and a second unidirectional throttle valve ( 160′ ). The electric control heat sink assembly ( 150 ) comprises an electric control component ( 151 ) and a heat dissipation assembly ( 152 ). The first unidirectional throttle valve ( 160 ), on the flow direction from a first valve port ( 161 ) to a second valve port ( 162 ), is completely turned on. On the flow direction from the second valve port ( 162 ) to the first valve port ( 161 ), the first unidirectional throttle valve ( 160 ) is a throttle component. The second unidirectional throttle valve ( 160′ ), on the flow direction from a third valve port ( 161′ ) to a fourth valve port ( 162′ ), is completely turned on. On the flow direction from the fourth valve port ( 162′ ) to the third valve port ( 161′ ), the second unidirectional throttle valve ( 160′ ) is a throttle component.

First claim

What is claimed is:

an outdoor heat exchanger and an indoor heat exchanger, wherein a first end of the outdoor heat exchanger is connected to the second port, and a first end of the indoor heat exchanger is connected to the third port;
a heat sink assembly comprising an electrical control element and a heat dissipation subassembly for heat dissipation of the electrical control element, wherein the heat dissipation subassembly is in series connection between a second end of the indoor heat exchanger and a second end of the outdoor heat exchanger;
a first one-way throttle valve comprising a first valve port and a second valve port, wherein the first valve port is connected to the second end of the outdoor heat exchanger and the second valve port is connected to the heat dissipation subassembly, in a flowing direction from the first valve port to the second valve port, the first one-way throttle valve is fully turned on, and in a flowing direction from the second valve port to the first valve port, the first one-way throttle valve is a throttling element; and
a second one-way throttle valve comprising a third valve port and a fourth valve port, wherein the third valve port is connected to the second end of the indoor heat exchanger, and the fourth valve port is connected to the heat dissipation subassembly, in a flowing direction from the third valve port to the fourth valve port, the second one-way throttle valve is fully turned on, and in a flowing direction from the fourth valve port to the third valve port, the second one-way throttle valve is a throttling element.

2. The air conditioner according to claim 1 , wherein the reversing assembly is configured as a four-way valve.

3. The air conditioner according to claim 1 , wherein the heat dissipation subassembly comprises:
a heat dissipation pipe in series connection between the indoor heat exchanger and the outdoor heat exchanger; and
a heat dissipation casing, wherein the heat dissipation pipe is disposed to the heat dissipation casing, and the heat dissipation casing is in contact with the electrical control element for the heat dissipation of the electrical control element.

4. The air conditioner according to claim 3 , wherein the heat dissipation casing comprises:
a heat dissipation substrate in contact with the electrical control element; and
a fixed baffle disposed on the heat dissipation substrate, wherein an accommodating space for accommodating the heat dissipation pipe is defined between the fixed baffle and the heat dissipation substrate.

5. The air conditioner according to claim 3 , wherein two ends of the heat dissipation pipe extend out from opposite sidewalls of the heat dissipation casing, so as to be connected to the first one-way throttle valve and the second one-way throttle valve respectively.

6. The air conditioner according to claim 3 , wherein two ends of the heat dissipation pipe extend out from the same side of the heat dissipation casing, so as to be connected to the first one-way throttle valve and the second one-way throttle valve respectively.

7. The air conditioner according to claim 4 , wherein an end surface of the heat dissipation substrate facing the fixed baffle is provided with a first groove, an end surface of the fixed baffle facing the heat dissipation substrate is provided with a second groove, and the first groove and the second groove are cooperated to define the accommodating space.

8. The air conditioner according to claim 7 , wherein cross sections of the first groove and the second groove are configured to be semicircle separately.

9. The air conditioner according to claim 4 , wherein the fixed baffle is provided with a fixed column, the heat dissipation substrate is provided with a fixed hole, and the fixed column and the fixed hole are connected by riveting.

10. The air conditioner according to claim 4 , wherein the accommodating space has the same shape as the heat dissipation pipe.
