Description

Lateral heat dissipation method and lateral hanging integrated phase change radiator Technical Field The invention relates to the technical field of radiators, in particular to a lateral radiating method and a lateral-hanging integrated phase-change radiator. Background The core of the phase change radiator is that the Phase Change Material (PCM) is utilized to absorb a great amount of heat in the process of solid state and liquid state (or liquid state and gaseous state), when the temperature is increased to the phase change temperature of the phase change material, the material absorbs heat and is converted into liquid state or gaseous state, thereby effectively reducing the temperature of the surrounding environment. The phase-change radiator in the prior art is generally composed of an evaporator and a condenser, wherein a phase-change medium is filled in the evaporator, the evaporator and a device (such as an IGBT) needing cooling and heat dissipation are attached to absorb heat of the device, the internal phase-change medium is heated and converted into a gaseous state, and the gaseous state is cooled by the condenser and then becomes a liquid state to flow back, so that the temperature of the device needing cooling and heat dissipation is kept constant. In general, a phase change radiator is generally vertically installed, and a gas-liquid circulation channel can be naturally formed by utilizing the principle of ascending and descending of a gaseous medium. However, in some situations, the phase-change radiator needs to be mounted in a side-hanging manner, that is, the evaporator is attached to the side surface of the device, and gaseous and liquid media cannot naturally form circulation, so that the application situations have higher requirements on the design of a gas-liquid circulation channel. To solve this problem in the prior art, the condenser is usually mounted at a higher level than the attachment area of the evaporator and the device (i.e., the heat receiving area of the evaporator), and a pipe connection is also usually used between the evaporator and the condenser. The design can naturally form a gas-liquid circulation channel by utilizing the principle of ascending and descending of a gaseous medium. However, the height space of the whole radiator occupies larger space, and for certain space-constraint application scenes, the gas-liquid circulation channel is difficult to establish when the heights of the condenser and the device needing to be cooled cannot be too different and even are on the same horizontal plane. In the application scene, the initial liquid injection height in the evaporator is already close to the height of the condenser, so that the gas-liquid circulation failure is further caused. Disclosure of Invention In order to solve the technical problem that a gas-liquid circulation channel is difficult to establish when a side surface of a device radiates heat, the invention provides a lateral heat radiation method, and provides a phase change radiator which comprises an evaporator and a condenser, wherein the evaporator and the condenser are provided with communicated gas-liquid exchange channels, and the phase change medium is injected into the evaporator, and the method specifically comprises the following steps: S1, laterally attaching a heat receiving area at the bottom of an evaporator to a heating device, and laterally connecting a condenser with the evaporator to enable a gas-liquid exchange channel to extend along the lateral direction; S2, enabling the gas-liquid exchange to form a circulation, namely, extending from the top of the evaporator to the end part of the condenser laterally through the top of the condenser and extending to the bottom of the evaporator along with the downward return flow of the end part of the condenser through the bottom of the condenser. Further, in the step S2, a blocking member is disposed between the evaporator and the condenser, so that the blocking member blocks the middle area of the gas-liquid exchange channel but opens the top and bottom areas of the gas-liquid exchange channel. Further, in the step S2, a downward extending gas-liquid flow channel is formed at the end of the condenser, and the downward extending gas-liquid flow channel flows through the bottom of the condenser to the bottom of the evaporator along with the end of the condenser in the gas-liquid exchange cycle. The side-hung integrated phase-change radiator comprises an evaporator and a condenser, wherein a phase-change medium is filled in the evaporator, a heat receiving area is arranged on one side of the evaporator, an evaporation area is arranged on the opposite side of the heat receiving area, the condenser is laterally connected to the evaporation area of the evaporator, a laterally-extending gas-liquid exchange channel is arranged between the evaporation area and the condenser, a blocking piece is connected to the evaporation area, and the upper end and t
