Embodiment 1

[0026] This embodiment provides a liquid dispenser head, such as Figure 1-2 As shown, it includes: a liquid dispensing top 1 and a liquid dispensing base 2 respectively connected to the pipeline, and a liquid mixing chamber 3 is also connected between the liquid dispensing top 1 and the liquid dispensing base 2, and the liquid mixing chamber 3 is from top to bottom A liquid separation orifice 31 for breaking the liquid into small liquid droplets and a mixing part 32 for mixing the refrigerant liquid droplets and the gaseous refrigerant and increasing the bubbles are sequentially arranged on the lower side. The liquid dispensing base 2 is uniformly opened with a plurality of liquid dispensing ports 21 connected with branch pipelines.

[0027] The liquid refrigerant enters from the liquid distribution top 1. At this time, because the speed of the liquid refrigerant is lower than that of the gas refrigerant, the liquid refrigerant is mostly on the inner wall of the channel, and ...

Embodiment 2

[0037] This embodiment also provides an air conditioner, wherein the liquid inlet pipe of the heat exchanger is further provided with the above-mentioned liquid distribution head.

[0038] To sum up, the gas-liquid mixing state of the refrigerant is more uniform through the mechanism of the liquid separation orifice used to break the liquid into small droplets and the mixing part that mixes the refrigerant droplets and gaseous refrigerant and increases the bubbles. Conducive to the average distribution of refrigerant. Compared with the dispensing head with jet ring and dispensing cone, this method has correspondingly lower requirements on machining accuracy. After the flow rate of the refrigerant enters the orifice plate structure, although the flow rate of the refrigerant decreases, the number of droplets increases, and the heat transfer surface area inside the heat exchanger will increase accordingly, which is conducive to improving the heat transfer coefficient. After the ...

Abstract

The invention relates to the technical field of liquid separation equipment, in particular to a liquid separation head and an air conditioner. The liquid separation head comprises a liquid separation top and a liquid separation seat which are connected with pipes correspondingly. A liquid mixing chamber is further connected between the liquid separation top and the liquid separation seat. The liquid mixing chamber is internally provided with a liquid separation hole plate and a mixing portion in sequence from top to bottom, wherein the liquid separation hole plate is used for breaking up liquid into small liquid drops, and the mixing portion is used for mixing refrigerant liquid drops with gas-state refrigerant and increasing bubbles. The liquid separation head is further arranged at a liquid inlet pipe of a heat exchanger of the air conditioner. By means of the structure composed of the liquid separation hole plate and the mixing portion, wherein the liquid separation hole plate is used for breaking up the liquid into the small liquid drops, and the mixing portion is used for mixing the refrigerant liquid drops with the gas-state refrigerant and increasing the bubbles, the air-liquid mixing state of the refrigerant can be more uniform, and it is beneficial to equal distribution of the refrigerant; the machining precision requirement is correspondingly low; it is helpful to increase the heat exchange coefficient; and the effect of relieving noise of an indoor unit of the air conditioner is achieved.

Description

technical field [0001] The invention relates to the technical field of liquid dispensing equipment, in particular to a liquid dispensing head and an air conditioner. Background technique [0002] In the existing small-scale refrigeration device, it involves the situation that the heat exchanger is divided into multiple channels. The throttled refrigerant is generally in the form of gas-liquid mixture. In order to ensure that the refrigerant is evenly distributed in each circuit, the common method is to use a liquid distributor. Connect the pipe or capillary to distribute the refrigerant evenly. [0003] In the prior art, the dispensing head is mostly vertically placed, which can eliminate the influence caused by gravity, but this method requires relatively high processing accuracy for the dispensing head. In fact, in many air-conditioning indoor units, due to limited space, The liquid distribution head is not placed vertically; at the same time, due to the later pipeline in...
