Description

Technical Field

[0001] The utility model belongs to the technical field of automobile radiators, and particularly relates to an automobile air-conditioning radiator with automatic switching between active and passive heat dissipation. Background Technique

[0002] An automobile air-conditioning radiator, usually referring to a condenser, mainly functions to help the air-conditioning system cool down and dissipate heat. In the air-conditioning system, the compressor compresses the refrigerant into a high-temperature and high-pressure gas state and then transports it to the condenser. In the condenser, the refrigerant releases heat and condenses into a liquid state. During this process, a radiator is required to dissipate the absorbed heat to maintain the normal operation of the refrigeration cycle. An automobile air-conditioning radiator usually uses the air suction principle for heat dissipation. When the vehicle stops, the fan sucks in external air to help the radiator cool down. During the vehicle's driving process, the fan will accelerate the air flow formed in front of the vehicle, making it enter the radiator faster and improving the heat dissipation effect. However, it still has the following disadvantages in actual use:

[0003] During the operation of the automobile air-conditioning radiator, it usually dissipates heat through passive heat dissipation when the vehicle is driving, and when the vehicle stops, it dissipates heat by blowing with the fan. Its main and passive control simply switches between heat dissipation based on the start and stop of the vehicle, without combining the actual working conditions during operation for main and passive control, which is prone to energy waste;

[0004] During the installation process of the automobile air-conditioning radiator in the vehicle, it is necessary to pre-determine the position of the refrigerant pipeline to be installed on it, and then adjust the installation position of the pipeline in advance. Subsequently, the refrigerant pipeline is installed at the position where the refrigerant is installed in the vehicle. During the installation process, the refrigerant pipeline is prone to insufficient applicability of the installation position, and the pipeline needs to be twisted to complete the installation. The applicability of the pipeline on the radiator to the installation of the refrigerant pipeline in the vehicle during installation is relatively poor. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automobile air-conditioning radiator with automatic switching between active and passive heat dissipation. By setting a radiator main body and a heat conduction block, the problems that the main and passive control of the automobile air-conditioning radiator is not adjusted according to the actual working conditions, is prone to energy waste, and the applicability of the pipeline on the radiator to the position of the refrigerant pipeline in the vehicle during installation is relatively poor are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to an automobile air conditioner radiator with automatic switching between active and passive heat dissipation, which comprises a radiator main body and a heat conducting block. The input end of the radiator main body is fixedly communicated with an input pipe, and the output end of the radiator main body is fixedly communicated with an output pipe. The heat conducting block is fixed on the periphery of the input pipe, and a connecting shell is fixed on the top of the heat conducting block. A fixing strip is fixed on the bottom of the inner wall of the connecting shell close to the radiator main body, a heat conducting plate is fixed on the side of the fixing strip away from the radiator main body, and reed pieces are fixed at two mutually separated edges at the top of the fixing strip and the heat conducting plate. During operation, the refrigerant entering the radiator main body is dissipated by the radiator main body. When the heat conducting block is working, the heat on the refrigerant conveyed in the input pipe is transferred to the heat conducting plate. The heat conducting plate expands due to heat and increases in length, so that the bending degree of the reed pieces is reduced, the first conductive rod and the second conductive rod are in contact with each other, and the fan is turned on.

[0008] Further, both ends of the input pipe and the output pipe away from the radiator main body are fixedly communicated with a transfer cavity, and a fixing ring is fixed at the end of the transfer cavity away from the radiator main body. The input pipe is transferred through the transfer cavity, and the sealing ring is movably connected therein through the fixing ring.

[0009] Further, a conveying elbow pipe is movably connected in the fixing ring, a sealing ring is fixed at the peripheral edge of the fixing ring close to the transfer cavity, the sealing ring is movably connected in the fixing ring, and the conveying elbow pipe is communicated with the transfer cavity. The fixing ring transfers and conveys the refrigerant through the conveying elbow pipe.

[0010] Further, exhaust frames are symmetrically fixed on the front side of the radiator main body along the horizontal center line, and a fan is fixed in the exhaust frames. The radiator main body fixes the fan in it through the exhaust frames. When the fan is working, air is drawn out from the radiator main body, so that the radiator main body conducts active heat dissipation.

[0011] Further, a second conductive rod is fixed at the center of the top of the heat conducting plate, and a first conductive rod is fixedly penetrated in the reed piece corresponding to the position of the second conductive rod. The heat conducting plate conducts electricity through the cooperation of the second conductive rod and the first conductive rod.

[0012] Further, a movable sleeve is movably connected to the periphery of the first conductive rod above the reed piece, and conductive plates are fixed at the middle parts of the peripheries of the movable sleeve and the second conductive rod. The conductive plates are fixedly penetrated on one side of the connecting shell. Through the conductive plates on the movable sleeve and the conductive plates on the second conductive rod, when working, the first conductive rod and the second conductive rod are electrified with the fan through wires.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the active and passive control of the automotive air conditioner radiator is not adjusted according to the actual working conditions, which is prone to energy waste, by setting a radiator main body and a heat conduction block. When the refrigerant exchanges heat in the radiator main body from the input pipe, the heat conduction plate is connected in the connection shell through a fixing strip and exchanges heat with the heat conduction block. When the temperature of the heat conduction block is too high, the heat conduction plate expands due to heat, increasing in length and driving the bending degree of the bent reed to decrease, driving the conductive rod I to descend, causing the conductive rod I and the conductive rod II to come into contact with each other. The two conductive plates extending out of the connection shell are respectively electrically connected to the two poles of the fan. After the conductive rod I and the conductive rod II come into contact with each other, the fan starts. When the fan works, it sucks air into the radiator main body, allowing external air to enter the radiator main body and then enter the exhaust frame for exhaust, for active heat dissipation, until the temperature of the refrigerant input in the input pipe drops, the heat conduction plate contracts, causing the reed to bend and the conductive rod I to rise and separate from the conductive rod II. At this time, the fan stops working, realizing the start-stop control of the fan and determining the active and passive automatic adjustment of the radiator. During operation, the active and passive control of the automotive air conditioner radiator can be automatically adjusted according to the actual working conditions, reducing energy waste.

[0015] The utility model solves the problem that the applicability of the pipeline on the radiator to the position of the refrigerant pipeline in the vehicle is poor during the installation of the automotive air conditioner radiator by setting a radiator main body. After the radiator main body is placed in the appropriate installation position in the vehicle, the position of the conveying elbow is immediately determined, and the most suitable guiding angle of the conveying elbow is selected. The conveying elbow is rotated so that the conveying elbow can be set in the vehicle at the most suitable angle, making the applicability of the pipeline on the radiator to the position of the refrigerant pipeline in the vehicle better during the installation of the automotive air conditioner radiator and more convenient to use.

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Specific embodiment 1

[0026] Please refer to Figures 1-5, the utility model is an automobile air conditioner radiator with automatic switching between active and passive heat dissipation, including a radiator main body 1 and a heat conduction block 3. The input end of the radiator main body 1 is fixedly communicated with an input pipe 101. The radiator main body 1 cools the refrigerant, and the evaporated refrigerant after cooling is transferred into the radiator main body 1 through the input pipe 101 from the conveying elbow 103. The output end of the radiator main body 1 is fixedly communicated with an output pipe 104. The radiator main body 1 outputs the cooled refrigerant into the transfer cavity 102 communicated with the output pipe 104 through the output pipe 104. A heat conduction block 3 is fixed on the periphery of the input pipe 101. When the refrigerant is input through the heat conduction block 3 into the input pipe 101, the heat on the refrigerant is transferred to the heat conduction plate 304. A connection shell 301 is fixed on the top of the heat conduction block 3. The fixing strip 302, the heat conduction plate 304 and the reed 303 are enclosed therein through the connection shell 301. A fixing strip 302 is fixed at the bottom of the inner wall of the connection shell 301 close to the radiator main body 1. A heat conduction plate 304 is fixed on the side of the fixing strip 302 away from the radiator main body 1. Reeds 303 are fixed at the two mutually distant edges of the top of the fixing strip 302 and the heat conduction plate 304. During operation, the heat conduction plate 304 is connected in the connection shell 301 through the fixing strip 302 and exchanges heat with the heat conduction block 3. When the temperature of the heat conduction block 3 is too high, the heat conduction plate 304 heats up and expands, increasing in length, driving the bending degree of the bent reed 303 to decrease, driving the first conductive rod 305 to descend, so that the first conductive rod 305 and the second conductive rod 308 come into contact with each other.

[0027] Specifically, the ends of the input pipe 101 and the output pipe 104 away from the radiator main body 1 are both fixedly communicated with a transfer cavity 102. A fixing ring 105 is fixed at the end of the transfer cavity 102 away from the radiator main body 1. The input pipe 101 and the output pipe 104 transfer the input and output of the refrigerant through the transfer cavity 102. The sealing ring 106 is movably connected in the transfer cavity 102 through the fixing ring 105.

[0028] Furthermore, a conveying elbow 103 is movably connected in the fixing ring 105. The end of the conveying elbow 103 away from the transfer cavity 102 is communicated with the pipeline for conveying the refrigerant in the automobile. A sealing ring 106 is fixed at the peripheral edge of the fixing ring 105 close to the transfer cavity 102. The sealing ring 106 is movably connected in the fixing ring 105. The conveying elbow 103 is communicated with the transfer cavity 102, so that when working, the end of the conveying elbow 103 away from the transfer cavity 102 can first determine the position, so that during operation, it can adapt to the positions of the refrigerant conveying pipelines of different automobiles.

[0029] Furthermore, exhaust frames 2 are symmetrically and fixedly arranged along the horizontal center line on the front side of the radiator body 1. A fan 201 is fixedly arranged inside the exhaust frame 2. When in passive heat dissipation, after air enters the radiator body 1, it is discharged through the exhaust frame 2. When the fan 201 operates, air is drawn into the radiator body 1, enabling external air to enter the radiator body 1 and then enter the exhaust frame 2 for exhaust, thereby performing active heat dissipation.

[0030] The operation process of this embodiment is as follows: During operation, first place the radiator body 1 at a suitable installation position in the vehicle, then determine the position of the conveying elbow 103, select the most suitable guiding angle of the conveying elbow 103, and rotate the conveying elbow 103 so that the conveying elbow 103 can be set in the vehicle at the most applicable angle. At this time, the refrigerant is conveyed to the transfer chamber 102 through the conveying elbow 103 in front of the input pipe 101, then conveyed to the input pipe 101 through the transfer chamber 102, conveyed to the radiator body 1 through the input pipe 101, and after being dissipated by the radiator body 1, it is conveyed to the output pipe 104. The refrigerant is conveyed to the transfer chamber 102 on the output pipe 104 through the output pipe 104, and then output to the output elbow in front of the output pipe 104 through the transfer chamber 102, and output to the equipment to be cooled through the output elbow. During operation, the conveying elbow 103 can reasonably set the position of the refrigerant pipeline according to the conveying position of the refrigerant pipeline of the radiator body 1, increasing the applicability of the radiator body 1 installed in the vehicle. Specific Embodiment 2

[0031] Please refer to Figures 1-6 Based on Specific Embodiment 1, a second conductive rod 308 is fixedly arranged at the center of the top of the heat conducting plate 304. A first conductive rod 305 is fixedly arranged through the reed 303 corresponding to the position of the second conductive rod 308. When the heat conducting plate 304 is separated from the first conductive rod 305 through the cooperation of the second conductive rod 308, the fan 201 is powered off. After the second conductive rod 308 contacts the first conductive rod 305, the fan 201 is turned on and starts to operate.

[0032] Specifically, a movable sleeve 306 is movably connected to the periphery of the first conductive rod 305 above the reed 303. Conductive plates 307 are fixedly arranged at the middle parts of the peripheries of the movable sleeve 306 and the second conductive rod 308. The conductive plates 307 are fixedly arranged through the side of the connection housing 301. The first conductive rod 305 electrically connects the conductive plate 307 to the first conductive rod 305 through the movable sleeve 306 all the time. By electrically connecting the two conductive plates 307 extending out of the connection housing 301 to the two poles of the fan 201 respectively, the fan 201 is started after the first conductive rod 305 contacts the second conductive rod 308.

[0033] The operation process of this embodiment is as follows: During operation, when the refrigerant exchanges heat in the radiator main body 1 from the input pipe 101, the heat conduction plate 304 is connected to the connection shell 301 through the fixing strip 302. After exchanging heat with the heat conduction block 3, when the temperature of the heat conduction block 3 is too high, the heat conduction plate 304 expands due to heat, increasing in length, driving the bending degree of the bent reed 303 to decrease, driving the first conductive rod 305 to descend, so that the first conductive rod 305 and the second conductive rod 308 come into contact with each other. The two conductive plates 307 extending out of the connection shell 301 are respectively electrically connected to the two poles of the fan 201. After the first conductive rod 305 and the second conductive rod 308 come into contact with each other, the fan 201 starts. When the fan 201 is working, it sucks air from the radiator main body 1, allowing external air to enter the radiator main body 1 and then enter the exhaust frame 2 for exhaust, performing active heat dissipation until the temperature of the refrigerant input in the input pipe 101 drops, the heat conduction plate 304 contracts, causing the reed 303 to bend, the first conductive rod 305 to rise, and separate from the second conductive rod 308. At this time, the fan 201 stops working, realizing the start-stop control of the fan 201 and determining the active and passive automatic adjustment of the radiator.
