Detailed Description

Fig. 1 and fig. 2 are a schematic structural diagram and a cross-sectional view of a liquid condenser according to an embodiment of the present application. As shown, the liquid condenser 100 includes a top plate 110, a condenser core 120, and a bottom plate (not shown). The condenser core 120 is arranged between the top plate 110 and the bottom plate, wherein the condenser core 120 comprises a plurality of flow plates 123, which are arranged one above the other and between which two adjacent flow plates a flow channel is formed. The refrigerant and the cooling liquid flow in the flow passage at intervals, that is, the refrigerant and the cooling liquid are separated by the flow plate and heat exchange is performed. A first header 121 and a second header 122 are respectively opened at both ends of the condenser core 120 for transferring a refrigerant. The top plate 110 is formed with a refrigerant inlet 111 corresponding to a first end of the first header pipe 121, and the bottom plate is formed with a refrigerant outlet (not shown) corresponding to a second end of the first header pipe 121. The condenser core 120 further includes at least one partition 124, and the partition 124 closes the first header 121 within the condenser core 120, dividing the condenser core 120 into a first passage 120a adjacent to the top plate 110 and a second passage 120b adjacent to the bottom plate. The ratio of the number of flow-through channels comprised by the first channel 120a to the number of flow-through channels comprised by the second channel 120b is greater than or equal to 2, i.e. the number of flow-through channels comprised by the first channel 120a is at least twice the number of flow-through channels comprised by the second channel 120 b.

Thus, when the refrigerant enters the liquid condenser 100 from the refrigerant inlet 110 provided in the top plate 110, it flows into the respective layers of the flow channels of the first channel 120a through the first header pipe 121. In this case, the refrigerant occupies a large volume because it is generally in a vapor state or a gas-liquid mixed state after being heated and pressurized. The provision of a plurality of flow plates forms a plurality of flow passages, thereby effectively increasing the capacity of the refrigerant entering the condenser core 120. Since the partition 124 blocks the first header pipe in the condenser core 120, the refrigerant is driven to advance in the first passage 120a in the arrow direction (as indicated by the arrow a), flows into the second passage 120b in the arrow direction when reaching the second header pipe 122 through the first flow path, and flows out through the refrigerant outlet 131 communicating with the first header pipe 121 through the second flow path in the arrow direction (as indicated by the arrow b). As the refrigerant flows through the flow passage, the refrigerant gradually releases heat, and the refrigerant gradually condenses from a gaseous state to a liquid state, and the volume of the refrigerant is reduced, so that the refrigerant is greatly reduced when entering the second flow path. Because the number of the circulation channels of the first channel 120a is at least twice that of the second channel 120b, the capacity of the refrigerant contained in the second channel 120b can be better matched with the capacity of the refrigerant contained in the first channel 120a, and under the condition of keeping a certain driving pressure, the change of the flow velocity caused by the condensation from the gas state to the liquid state can be avoided, the flow velocity of the refrigerant can be better ensured, and the heat release efficiency of the refrigerant is greatly improved.

The liquid condenser occupies a larger volume because the refrigerant is in a steam state when entering the liquid condenser, and the volume is correspondingly reduced as the refrigerant gradually releases heat in the condenser and is gradually condensed from a gas state to a liquid state. Therefore, the refrigerator channel is divided into the first channel and the second channel by the partition plate, the ratio of the number of the circulation channels of the first channel to the number of the circulation channels of the second channel is larger than or equal to 2, so that the refrigerant passes through at least two flows in the liquid condenser, the capacity of the first flow is at least twice of that of the second flow, and the heat release efficiency of the refrigerant can be effectively improved under the condition of balancing power consumption and flow speed.

In one embodiment, the ratio of the number of flow-through channels included in the first channel 120a to the number of flow-through channels included in the second channel 120b ranges from 2 to 3. That is, when the number of the flow channels in the first channel 120a is two to three times as many as the number of the flow channels in the second channel 120b, the heat-releasing efficiency of the liquid condenser is optimized.

In one embodiment, the baffle 124 and the flow-through plate 123 are integrally formed. That is, the baffle plate and the flow plate on the layer where the baffle plate is positioned are integrally formed, and only the opening of the first liquid collecting pipe is not arranged in the production process of the layer of flow plate, so that the production is more convenient, and the sealing property can be ensured.

In one embodiment, the flow-through plate 123 is made by a stamping process, which is simple and can reduce costs.

In one embodiment, a spoiler 125 is also disposed on each flow plate 123. The spoiler 125 is provided to further accelerate heat release and improve heat release efficiency.

In one embodiment, the first and

second header pipes

121 and 122 are opened at diagonal ends of the condenser core 120. Such an arrangement can lengthen the length of each flow path as much as possible, thereby enabling the heat release to be more sufficient.

In one embodiment, the liquid condenser 100 is a plate heat exchanger or a plate fin heat exchanger. The liquid condenser 100 may be of the plate heat exchanger or plate fin heat exchanger type, and is more widely used.

In one embodiment, the liquid condenser 100 further includes an upper end plate 130 connected to the top plate 110 and a lower end plate (not shown) connected to the bottom plate. Wherein the upper end plate 130 includes a first joint 131 corresponding to the refrigerant inlet 111 and the lower end plate includes a second joint 141 corresponding to the refrigerant outlet 121. The first joint that can pass through the top plate is connected with the compressor, and the second through lower end plate connects with the liquid storage pot, conveniently dismantles and maintains.

In one embodiment, the upper end plate 130 is further provided with a coolant inlet pipe 132 and a coolant outlet pipe 133 at both ends thereof, respectively. The coolant may flow in from the coolant inlet pipe 132 and then flow out from the coolant outlet pipe 133 after heat absorption in one process. The cooling liquid inlet pipe and the cooling liquid outlet pipe are arranged on the same side of the liquid condenser, and installation is facilitated. It will be appreciated that the condenser core also comprises a third header and a fourth header for conveying the cooling liquid. In this embodiment, the lower end plate closes one ends of the third and fourth liquid collecting tubes, and the other ends of the third and fourth liquid collecting tubes correspond to the coolant inlet tube 132 and the coolant outlet tube 133, respectively.

In one embodiment, the upper end plate 130 has a coolant inlet pipe and the lower end plate has a coolant outlet pipe. Therefore, the cooling liquid inlet pipe and the cooling liquid outlet pipe are respectively arranged on two sides of the liquid condenser, so that the heat absorption flow of the cooling liquid in the liquid condenser can be increased as much as possible, and the heat absorption efficiency is improved. In this embodiment, it can be understood that one end of the third header pipe is communicated with the coolant inlet pipe, and the other end is closed by the lower end plate; one end of the fourth liquid collecting pipe is communicated with the cooling liquid outlet pipe, and the other end of the fourth liquid collecting pipe is sealed by the upper end plate.

It will be appreciated that in one embodiment, the coolant flow channels in the condenser core may also be designed as two-pass channels.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
