Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 , a heat exchanger oil chamber structure shown in the figure includes a heat exchange cavity 1, and also includes a pressure reducing component arranged in the heat exchange cavity 1 for reducing the pressure of the internal high-pressure steam;

[0023] The pressure reduction component includes a pressure reduction pipe 201 arranged in the heat exchange cavity 1, one end of the pressure reduction pipe 201 is connected to the inside of the heat exchange cavity 1, and the other end of the pressure reduction pipe 201 is provided with a micro gas-liquid separator 203, the side of the micro gas-liquid separator 203 away from the heat exchange cavity 1 is provided with an air outlet pipe 204, and the side of the micro gas-liquid separator 203 close to the heat exchange cavity 1 is provided with a liquid outlet pipe 205, the heat exchange cavity 1 is provided with a cooling component for cooling the separated liquid, and the pressure reduction pipe 201 is provided with a release component for intermittently releasing the high-pressure steam in the heat exchange cavity 1;

[0024] It should be noted here that: through the setting of the pressure reducing component, in the process of intermittent release of high-pressure steam by the release component, the pressure in the heat exchange cavity 1 is gradually reduced, thereby avoiding damage to the seals, pipelines or other related components of the heat exchanger due to excessive internal pressure in the heat exchange cavity 1, thereby ensuring heat exchange while reducing damage to the heat exchanger.

[0025] It is worth noting that: as existing technologies, the specific structure and working principle of the heat exchanger and the micro gas-liquid separator 203 have been mastered by those skilled in the art, and will not be elaborated herein.

[0026] See also Figure 3 , the pressure reducing tube 201 shown in the figure is provided with a pressure sensor 202;

[0027] It should be noted here that the pressure sensor 202 is provided to facilitate detection of the pressure in the heat exchange cavity 1 .

[0028] It is worth noting that: as a prior art, the specific structure and working principle of the pressure sensor 202 have been mastered by those skilled in the art, and will not be elaborated herein.

[0029] See also Figure 2 and Figure 3The cooling component shown in the figure includes a condensing box 301 arranged on the side of the heat exchange cavity 1 close to the micro gas-liquid separator 203, and two symmetrically arranged support plates 302 are provided on the side of the condensing box 301 close to the heat exchange cavity 1. The other ends of the two support plates 302 are connected to the heat exchange cavity 1, and the liquid outlet pipe 205 of the micro gas-liquid separator 203 is connected to the liquid inlet end of the condensing box 301 through the first connecting pipe, and the liquid outlet end of the condensing box 301 is connected to the heat exchange cavity 1 through the second connecting pipe 303;

[0030] It should be noted here that: by setting up the cooling component and utilizing the cooling effect of the condenser 301, the separated liquid is further cooled before flowing into the heat exchange cavity 1, thereby being used to cool the high-temperature oil in the heat exchange cavity 1 and avoiding the continuous generation of steam due to the continuous high temperature of the oil in the heat exchange cavity 1.

[0031] It is worth noting that: as a prior art, the specific structure and working principle of the condensation box 301 have been mastered by those skilled in the art, and will not be elaborated herein.

[0032] Working principle: During the heat exchange process of the heat exchanger, the heat source in the fluid channel on the heat source side enters the heat exchange cavity 1 through the pipeline, and passes through the pipeline and heat exchange surface inside the heat exchange cavity 1 to transfer the heat to the heat load in the fluid channel on the heat load side, thereby achieving the purpose of heat exchange;

[0033] When the high-temperature oil in the heat exchange cavity 1 is in the process of continuous flow and heat exchange, due to the continuous accumulation of temperature and insufficient heat exchange, the oil temperature in the oil chamber of the heat exchanger will exceed its normal operating temperature range, causing the water in the high-temperature oil to evaporate and form steam. As the steam continues to increase, the steam pressure in the oil chamber will gradually increase, resulting in excessive pressure inside the oil chamber. When the pressure sensor 202 detects that the pressure of the heat exchange cavity 1 is too high, it will send an electrical signal to the controller. Under the control of the controller, the release component is used to intermittently release the high-pressure steam in the heat exchange cavity 1, so that the high-pressure steam in the heat exchange cavity 1 will overflow from the pressure reducing pipe 201.

[0034] And because the internal pressure of the heat exchange cavity 1 is too high, during the process of high-pressure steam being released from the pressure reducing pipe 201, a certain amount of oil will flow out. When the high-pressure steam containing a certain amount of oil flows from the pressure reducing pipe 201 to the micro gas-liquid separator 203, it will be separated by using the principle of different specific gravity of gas and liquid components. After the gas-liquid mixture enters the micro gas-liquid separator 203, it collides with the baffle and rotates at a certain speed along the spiral channel, and the liquid is separated by centrifugal force. In the cyclone, the liquid is further separated from the gas by reducing speed and changing direction. The working principle of the micro gas-liquid separator 203 is only briefly described here. After gas-liquid separation, the liquid flows into the condensation box 301 through the liquid outlet pipe 205, and the gas flows out from the gas outlet pipe 204, thereby releasing the high-pressure steam while achieving gas-liquid separation to avoid waste of oil.

[0035] After the high-temperature steam is separated by gas pressure, it will flow from the liquid outlet pipe 205 to the condenser box 301. The separated liquid will be further cooled by the cooling effect of the condenser box 301 and then flow into the heat exchange cavity 1, so as to cool the high-temperature oil in the heat exchange cavity 1 and avoid the continuous generation of steam due to the continuous high temperature of the oil in the heat exchange cavity 1, thereby ensuring heat exchange while reducing damage to the heat exchanger.

[0036] Example 2

[0037] See also Figure 4 , this embodiment further explains Example 1, the release assembly in the figure includes a first release plate 401 fixedly connected to the pressure reducing tube 201, the first release plate 401 is connected to the second release plate 402 via a rotating shaft 404 on the side away from the pressure sensor 202, the first release plate 401 and the second release plate 402 are both provided with a plurality of release holes 403, and the pressure reducing tube 201 is provided with a driving assembly for driving the second release plate 402;

[0038] It should be noted here that: by setting up the release component, the high-pressure steam in the heat exchange cavity 1 is released intermittently, thereby avoiding excessive pressure fluctuations inside the heat exchange cavity 1 due to rapid pressure release, thereby further reducing the impact on liquid flow and heat exchange in the heat exchange cavity 1.

[0039] See also Figure 4 The driving assembly shown in the figure includes two mutually symmetrically arranged guide rods 501 fixedly connected to the inner wall of the pressure reducing tube 201, the two guide rods 501 are slidably connected to guide plates, the two guide plates are fixedly connected to racks 502 on opposite sides, the end of the rotating shaft 404 away from the first release plate 401 passes through the second release plate 402 and is fixedly connected to a gear 504, and the gear 504 and the rack 502 are meshed with each other;

[0040] It should be noted here that: through the setting of the driving component, under the reciprocating pushing action of the push rod motor 505, the rack 502 will be driven to move reciprocatingly, and under the reciprocating meshing transmission action of the rack 502 and the gear 504 and the guiding action of the guide rod 501 and the guide plate, the second release plate 402 will be driven to rotate reciprocatingly. During the reciprocating rotation of the second release plate 402, the release holes 403 on the first release plate 401 and the release holes 403 on the second release plate 402 will reciprocate with each other or staggered, thereby releasing the high-pressure steam in the heat exchange cavity 1, thereby avoiding excessive pressure fluctuations in the heat exchange cavity 1 due to the rapid release of pressure, thereby further reducing the impact on the liquid flow and heat exchange in the heat exchange cavity 1.
