The utility model is applied to the refrigerator. The refrigerator can control the cold pipe to cool the heat pipe by controlling the first electromagnetic valve. Thus, the side plate condenser is cooled down by using water as compared with the case where the water pump is turned on. The utility model controls the first electromagnetic valve to enable the cold pipe to radiate heat of the heat pipe. The waste of energy is reduced.

Wherein the side plate condenser 1 comprises a cold pipe 3 and a heat pipe 4. The heat pipe 4 is connected with a first input end of the first electromagnetic valve 2; the cold pipe 3 is connected to a first output of the first solenoid valve 2. The heat pipe 4 is used for heat release; the cold pipe 3 is used for cooling the heat pipe. And the first electromagnetic valve 2 is used for controlling the cold pipe to cool the heat pipe.

By adopting the refrigerator refrigeration pipeline provided by the embodiment of the disclosure, the cooling pipe can be controlled to cool the heat pipe by controlling the first electromagnetic valve. Thus, the side plate condenser is cooled down by using water as compared with the case where the water pump is turned on. The utility model controls the first electromagnetic valve to enable the cold pipe to radiate heat of the heat pipe. The waste of energy is reduced. Thereby saving the heat dissipation energy of the side plate condenser.

In some embodiments, the cold and heat pipes are spirally wound or arranged in parallel, in contact with each other. In this way, the refrigerant in the cold pipe can sufficiently dissipate heat from the heat pipe.

In some embodiments, the cold pipe cools the heat pipe with the first output of the first solenoid valve in an open state. Under the condition that the first output end of the first electromagnetic valve is not in an open state, the cold pipe does not cool the heat pipe.

The first electromagnetic valve is used for controlling the cold pipe to cool the heat pipe under the condition that the environmental temperature value is greater than or equal to the preset temperature. Thus, since the temperature of the refrigerator side plate is higher than the ambient temperature. And detecting the ambient temperature to obtain an ambient temperature value. The temperature of the refrigerator side plate can be reflected. The side plate condenser is convenient to cool under the condition that the temperature of the side plate is too high so as to cool the side plate. Thereby reducing the probability of the user being scalded.

Alternatively, the heat pipe is used to release heat from the first refrigerant. Refrigerator refrigeration pipeline still includes: a first throttle valve. The heat pipe is connected with a first input end of the first electromagnetic valve through a first throttle valve. The first throttle valve is used for reducing the temperature and the pressure of the first refrigerant to obtain a second refrigerant. In this way, the first refrigerant after radiating through the heat pipe is cooled down and depressurized again through the first throttle valve. So that the second refrigerant after temperature and pressure reduction can cool the heat pipe through the cold pipe. The cooling efficiency is improved.

As shown in conjunction with fig. 2, an embodiment of the present disclosure provides a refrigeration circuit of a refrigerator, including: a side plate condenser 1, a first solenoid valve 2, and a first throttle valve 5.

The first throttle valve is used for reducing the temperature and the pressure of the first refrigerant to obtain a second refrigerant.

In some embodiments, with the first output of the first solenoid valve in an open state, the first refrigerant releases heat through the heat pipes of the side plate condenser, initially reducing the temperature of the first refrigerant. And then cooling and depressurizing again through the first throttle valve to obtain a second refrigerant. The second refrigerant passes through the first input end to the first output end of the first solenoid valve and exchanges heat with the heat pipe through the cold pipe. The cooling of the heat pipe side plate condenser is realized.

Optionally, the refrigerator refrigeration pipeline further includes: and a second throttle valve. The cold pipe is connected with the first output end of the first electromagnetic valve through the second throttle valve. The second throttle valve is used for controlling the flow of the second refrigerant passing through the cold pipe. In this way, the flow rate of the second refrigerant passing through the cold pipe can be controlled by the second throttle valve. The heat pipe can be prevented from being cooled by the excessive second refrigerant flow value cold pipe. So that the heat pipe temperature is too low to make the side plate temperature too low. Thereby reducing the probability of condensation generation caused by the too low temperature of the side plate.

Further, there are two second temperature sensors. A second temperature sensor is used for detecting the temperature of a side plate of the left side plate of the refrigerator. The other second temperature sensor is used for detecting the temperature of a side plate of the side plate on the right side of the refrigerator. The second throttle valve is used for controlling the flow of the second refrigerant passing through the cold pipe according to the temperature value of the side plate. The side plate temperature value is the highest temperature value detected in the two second temperature sensors. In some embodiments, the side panel temperature of the side panel on the left side of the refrigerator is higher than the side panel temperature of the side panel on the right side of the refrigerator, i.e., the side panel temperature value is the side panel temperature of the side panel on the left side of the refrigerator. And the maximum value of the left temperature value and the right temperature value is determined as a side plate temperature value, so that the condenser can be conveniently cooled according to the side plate temperature value.

Optionally, the second solenoid valve is further configured to reduce the backflow of the second refrigerant to the cold pipe.

In some embodiments, the first output end of the first electromagnetic valve is controlled to be in a closed state under the condition that the heat pipe does not need to be cooled, that is, under the condition that the ambient temperature value is smaller than the preset temperature. So as to control the cold pipe not to cool the heat pipe. At the same time, the second input end of the second electromagnetic valve is controlled to be in a closed state. The probability of refrigerant flowing back through the evaporator to the cold pipe can be avoided.

In some embodiments, the compressor applies work to the refrigerant with the first output of the first solenoid valve in an open state. The high-temperature and high-pressure first refrigerant releases heat through the heat pipes of the side plate condenser, and the temperature of the first refrigerant is primarily reduced. And then cooling and depressurizing again through the first throttle valve to obtain a second refrigerant. A portion of the second refrigerant passes through the first input end of the first solenoid valve to the first output end and exchanges heat with the heat pipe through the cold pipe.

In some embodiments, the circulation path of the refrigerant is a first circulation path with the first output of the first solenoid valve and the second input of the second solenoid valve in a closed state: the heat pipe of the compressor-condenser-the first throttle valve-the first input of the first solenoid valve-the second output of the first solenoid valve-the evaporator-the third input of the second solenoid valve-the third output of the second solenoid valve-the compressor. At this time, no second refrigerant flows through the cold pipe, the heat pipe is not cooled, and the temperature of the side plate is not reduced.

Thus, by controlling the first output of the first solenoid valve and the second input of the second solenoid valve to be in a closed state. The refrigerating agent can only circulate through the first circulation path, so that all the refrigerating agent can refrigerate the freezing chamber through the evaporator, and the refrigerating effect of the refrigerator is improved.

In some embodiments, the circulation path of the refrigerant is the second circulation path with the first output of the first solenoid valve and the second input of the second solenoid valve in an open state.

Thus, the second refrigerant cooled by the first throttle valve is divided into two at the first solenoid valve. A part of the refrigerant reaches the evaporator to cool the freezing chamber according to the original route, namely a circulation route 1. And a part of the air passes through the second throttle valve to reach the cold pipe to cool the heat pipe. Thereby the side plate where the evaporator is located can be cooled.
