Furthermore, in the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In order to reduce the influence of hot air generated during bath on the lamp body 100, the invention fully utilizes the temperature difference generated during bath between the bottom of the ceiling 110 and the top of the ceiling 110 in the bathroom to assist the lamp body 100 in cooling. To this end, the invention provides a lighting fixture with a cooling device.
Referring to fig. 1 and 2, the heat exchanger comprises a lamp body 100 arranged on a ceiling 110, a condensing channel 200 arranged on the ceiling 110, and a heat exchanging part 300 arranged on a heat radiating part of the lamp body 100, wherein when the lamp is in bath, a low temperature area 101 is formed at the top of the ceiling 110, and a high temperature area 102 is formed at the bottom under the influence of hot air; the condensing passage 200 is in a state that the bottom temperature is high and the top temperature is low to condense the hot gas into liquid when the hot gas is transferred to the top of the condensing passage 200, and the heat exchanging part 300 is used for receiving the condensed liquid and exchanging heat to the heat radiating part of the lamp body 100 by using the low temperature of the liquid.
Wherein: the bottom end of the condensation channel 200 is sleeved with a conduction part, and the conduction part is connected with the heat dissipation part of the lamp body 100 and is used for conducting heat of the heat dissipation part of the lamp body 100 to the bottom end of the condensation channel 200, so that the condensation channel 200 forms a state with high bottom end temperature and low top end temperature.
Fig. 2 to 7 show embodiment 1 of the present invention.
As shown in fig. 2, the lamp body 100 includes a lamp body 111, wherein the lamp body 111 is fixedly mounted on a ceiling 110 through spring buckles on two sides of the lamp body 111 (the positions of the spring buckles can be seen in fig. 1), and a light-transmitting plate 112, a light-reflecting cup 113, a light source 114 and a heat sink 115 are sequentially arranged in the lamp body 111 from bottom to top; wherein the light-transmitting plate 112 is located in the high temperature region 102, and the reflector cup 113, the light source 114, and the heat sink 115 are located in the low temperature region 101. Thus, the heat at the bottom end of the lamp body 111 and the light-transmitting plate 112 is conducted to the heat sink 115 through the ceiling 110, thereby achieving the purpose of heat dissipation.
However, when the bath is performed, the hot air generated from the hot water has a certain temperature (particularly in winter), the hot air rises to the bottom of the ceiling 110, so that the heat of the light-transmitting plate 112 and the bottom of the lamp body 111 is quickened, and the distance between the ceiling 110 and the roof, that is, the temperature of the low temperature region 101 is significantly lower than the temperature of the bottom of the ceiling 110, that is, the temperature of the high temperature region 102. Thus, the condensation is accomplished by delivering hot gas to the low temperature zone 101 through the condensation channel 200. The specific structure is as follows:
in fig. 2, an air inlet 116 is formed at the bottom of the lamp body 111;
in fig. 3, the condensation channel 200 includes a gas pipe 210 fixedly disposed at the top of the lamp body 111 and communicated with the gas inlet 116, a conducting portion sleeved on an outer ring at the lower end of the gas pipe 210, and a receiving portion 220 disposed in the gas pipe 210 for conveying liquid generated during condensation to the heat exchange portion 300.
In operation, as shown in fig. 7, the dashed arrows indicate the floating direction of the hot gas, and the solid arrows indicate the flow direction of the condensed liquid. Specifically, the hot air floats upward and enters the air delivery pipe 210 through the air inlet 116, and immediately after entering the air delivery pipe 210, the bottom of the air delivery pipe 210 has high temperature due to the existence of the conducting part, so that the hot air cannot be condensed at the part. When the hot air floats up to the top end of the air delivery pipe 210, the top end of the air delivery pipe 210 is at a lower temperature due to no contact with the conducting part, so that the hot air at the position is condensed, and at the moment, the liquid generated by condensation flows downwards to the bearing part 220 along the side wall of the air delivery pipe 210.
Next, fig. 4 and 5 disclose a specific structure of the receiving unit 220.
In fig. 4, the receiving portion 220 includes an inner ring 221 fixedly provided on an inner ring of the air delivery pipe 210; in fig. 5, a diversion trench 222 is provided at the top of the inner ring 221. Thus, liquid located on the inner wall of the air delivery pipe 210 enters the diversion trench 222 during the downward flow. The inner ring 221 has a flow guide pipe 224 provided on a side wall thereof and communicating with the flow guide groove 222, and one end of the flow guide pipe 224 communicates with the heat exchanging unit 300. So that the liquid in the guide groove 222 can flow into the heat exchanging part 300 along the guide pipe 224.
And the heat exchanging part 300 is constructed as shown in fig. 6. The heat conducting block 310 is fixedly sleeved on the outer ring of the ceiling 110, the top of the heat conducting block 310 is provided with a liquid storage cavity 311, and the liquid storage cavity 311 is communicated with one end of the flow guiding pipe 224. In this way, the liquid in the guide pipe 224 enters the liquid storage cavity 311 to absorb the heat of the heat conducting block 310, so that the heat conducting block 310 absorbs the heat of the cooling fin 115, and the cooling of the cooling fin 115 is fast.
Further, the conducting part includes a heat conducting fin 230 sleeved on the outer ring of the air pipe 210, and a heat conducting ring 231 sleeved on the outer ring of the heat sink 115 is fixedly connected to the side wall of the heat conducting fin 230.
That is, when bathing, the heat in the low temperature region 101 is conducted to the high temperature region 102 by utilizing the characteristic that the ceiling 110 partitions the room into the low temperature region 101 and the high temperature region 102, and the condensed liquid is sent to the heat exchanging part 300 by cooperating with the receiving part 220, thereby lowering the temperature of the heat sink 115.
Furthermore, in order to reduce the entry of hot gas into the low temperature region 101, the low temperature region 101 is excessively humid.
Please refer to fig. 3 and 4:
the top of the gas pipe 210 is fixedly provided with a reaction tower 211, the bottom of the reaction tower 211 protrudes downwards, and a gap 212 is formed between the reaction tower 211 and the top of the gas pipe 210. On the other hand, the inner ring 221 is fixedly connected with a guide bowl 223, and the guide bowl 223 is communicated with the guide groove 222. In this way, when part of the hot gas is discharged into the low temperature region 101 through the gas pipe 210, the hot gas is contacted with the reaction tower 211, and because the reaction tower 211 is located in the low temperature region 101, the low temperature of the reaction tower 211 also causes the hot gas to condense, and the condensed liquid drops to the guide bowl 223 through the convex part at the bottom of the reaction tower 211, and then flows into the liquid storage cavity 311 through the guide groove 222 and the guide pipe 224. In addition, a heat conducting rod can be arranged at the top of the reaction tower 211, and one end of the rod is connected with a wall, so that the temperature of the reaction tower 211 is continuously reduced, and the condensation efficiency is improved.
Fig. 8 shows embodiment 2 of the present invention.
It is considered that the cooled liquid will also slowly heat up after cooling down, thereby causing the liquid to evaporate into water vapor and float into the low temperature region 101, which in turn exacerbates the phenomenon of excessive humidity in the low temperature region 101. To this end:
the liquid storage cavity 311 is of a sealing structure, a sliding groove for the pillar 240 to longitudinally slide is formed in the top of the gas pipe 210, and a memory spring 241 for elastically connecting the bottom end of the sliding groove and the bottom of the pillar 240 is arranged between the bottom end of the sliding groove and the bottom of the pillar 240; the side wall of the flow guide pipe 224 is communicated with an air guide pipe 242, and one end of the air guide pipe 242 is communicated with the chute. The memory spring 241 has a low-temperature state in an extended state and a high-temperature state in a compressed state.
During operation, heat generated by the lamp body 100 is conducted into the liquid storage cavity 311 through the cooling fins 115, so that liquid evaporates in the liquid storage cavity 311 and is discharged through the flow guide pipe 224 and the air guide pipe 242, and water vapor discharged through the air guide pipe 242 contacts with the memory spring 241, so that the memory spring 241 is heated, compressed and pulls the reaction tower 211 to move downwards, and the reaction tower 211 covers the top of the air pipe 210 to seal the top of the air pipe 210. Subsequently, the gas discharged through the flow guide pipe 224 is discharged into the gas pipe 210 through the flow guide groove 222, and is merged into the high temperature region 102.
When the water vapor is in the air pipe 210, the heat is conducted to the air pipe 210 by the heat conducting fin 230, so that the water vapor in the air pipe 210 is not easy to condense again, and the phenomenon that the water vapor becomes liquid in the air pipe 210 drops is avoided.
Therefore, after the bath is completed, through the cooperation among the heat conducting block 310, the memory spring 241, the reaction tower 211 and the heat conducting fin 230, part of the liquid in the liquid storage cavity 311 is evaporated to the memory spring 241 to deform the memory spring 241, so that the reaction tower 211 is forced to cover the gas pipe 210, and hot gas in the gas pipe 210 cannot enter the low-temperature area 101, so that the phenomenon of excessive humidity in the low-temperature area 101 is not caused while the gas is discharged.
Considering that the light-transmitting plate 112 at the bottom of the lamp body 100 generates higher heat even after long-term operation, but the light-transmitting plate 112 is easily broken when the temperature is lowered at higher temperature, in order to achieve the lowering of the temperature of the light-transmitting plate 112, fig. 7 and 9 show embodiment 3 of the present invention.
As shown in the figure, the top outer ring of the light-transmitting plate 112 is provided with a liquid storage tank 120, two groups of receiving parts 220 in each ceiling 110 are longitudinally arranged, and the receiving part 220 at the bottom is communicated with the liquid storage tank 120 through a flow guide pipe 224.
When the lamp body 100 is in operation, the temperature of the lamp body is conducted to the gas pipe 210 through the heat conducting sheet 230, so that the gas in the gas pipe 210 is difficult to condense into liquid, and the temperature of the light-transmitting plate 112 is not reduced. When the temperature of the lamp body 100 starts to decrease, the temperature conducted into the air delivery pipe 210 decreases, and at this time, the water vapor in the air delivery pipe 210 is condensed to form a liquid under the influence of the low temperature. The light-transmitting plate 112 is then cooled by directing the liquid to the reservoir 120.
In summary, the liquid storage tank 120 and the heat conducting fin 230 cooperate with each other, so that the vapor in the air pipe 210 reacts according to the conduction of the heat conducting fin 230, and condensed liquid is generated only when the temperature becomes low, so that the temperature of the light-transmitting plate 112 starts to be reduced, and the occurrence of fragmentation caused by temperature reduction at high temperature is avoided.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed.
