Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and in particular to a radiation refrigerator. Background Art

[0002] In the living environment of existing users, there is usually a need for cooling in localized hot areas. For example, when a user is cooking in the kitchen, the cooking fire and exercise will generate a lot of heat, causing the user to sweat profusely. Generally, users do not install air-conditioning equipment in the kitchen, or only have ventilation equipment, which cannot achieve good cooling and heat exchange effects. Existing radiation cooling methods mostly exchange energy through heat transfer. However, the human body continuously generates heat energy, which hinders the low temperature emitted by the radiation panel from being transferred to the human body surface, resulting in slow transfer of cold to the user's location, which in turn leads to low cooling efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a radiation refrigerator, which solves the problem that when the existing refrigeration equipment in the prior art adopts radiation cooling, the cold energy of the radiation plate is slowly transferred to the user's location, resulting in low cooling efficiency.

[0005] The beneficial effects of the present invention are as follows: by moving the device to a predetermined position, and then starting the refrigeration unit to inhale the working medium, the refrigeration unit cools the working medium and then transports it to the first working medium pipe, the first working medium pipe transports the low-temperature working medium to the transfer component, the transfer component is coated with a radiation plate, the heat on the radiation plate is transferred to the low-temperature working medium through the transfer component, causing the temperature of the radiation plate to decrease, and after the temperature of the radiation plate decreases, it absorbs the heat around the radiation plate, causing the temperature of the air around the radiation plate to decrease, thereby achieving refrigeration, the horizontal cross-section of the radiation plate is a parabola, and the first working medium pipe is at the focus of the parabola, so that when the heat emitted by the human body is radiated to the radiation plate in the form of electromagnetic waves, the radiation plate reflects the heat to the first working medium pipe, the temperature of the first working medium pipe is lower than the temperature of the radiation plate, so that the first working medium pipe can absorb a large amount of heat radiation from the human body, and the first working medium pipe absorbs the heat and then transports it to the refrigeration unit for cooling again, thereby quickly reducing the heat radiation emitted by the human body in the area to be refrigerated, and improving the efficiency of radiation refrigeration of the device.

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown in FIG. 4 , an embodiment of the present invention provides a radiation refrigerator, comprising a first working fluid tube 4, one end of which is connected to the output end of the refrigeration unit, and the other end is connected to a transfer component, and the end of the transfer component away from the first working fluid tube 4 is connected to the input end of the refrigeration unit; a radiation plate 3, which is connected to the transfer component, and the transfer component is used for heat transfer with the radiation plate 3, and the cross-section of the radiation plate 3 in the horizontal direction is a parabola, and the focus of the parabola of the radiation plate 3 coincides with the axis of the first working fluid tube 4. Specifically, the refrigeration unit can be arranged in the box body 1, and one end of the first working fluid pipe 4 away from the refrigeration unit extends out of the box body 1. When working, by moving the box body 1 to the position to be used, and then starting the refrigeration unit, the refrigeration unit inhales the working fluid to cool the working fluid. The working fluid can be air or refrigerant. The low-temperature working fluid is output by the refrigeration unit to the first working fluid pipe 4. The first working fluid pipe 4 transports the low-temperature working fluid to the transfer component. The radiation plate 3 coated on the transfer component then transfers the cold energy to the outside to cool the outside. The heat radiation of the human body is mainly dissipated to the outside in the form of infrared rays. The radiation plate 3 can be arranged in an arc shape. After receiving the heat radiation emitted by the human body, the radiation plate 3 transfers part of the heat Absorb and reflect part of the heat, because the horizontal cross-section of the radiation plate 3 is a parabola, and the first working fluid tube 4 is arranged at the focus of the parabola, and because the temperature of the first working fluid tube 4 is lower than the heat radiation temperature reflected by the radiation plate 3, the first working fluid tube 4 can absorb most of the reflected heat radiation, and the first working fluid tube 4 absorbs the heat and transports the heat to the refrigeration part through the working fluid, so that the heat emitted by the human body can be quickly transported to the refrigeration part. Preferably, the outer surface of the first working fluid tube 4 is black oxidized, which can better absorb the heat radiation, so that the device can quickly cool down the position, and improve the efficiency of radiation refrigeration. The refrigeration part can use the conventional compressor and heat exchanger in the refrigeration machine in the prior art, and its structure and connection belong to the conventional means in this field, so it will not be repeated.

[0022] like Figure 2As shown, further, the transmission component includes: a second working fluid pipe 5, the second working fluid pipe 5 is connected to the end of the first working fluid pipe 4 away from the refrigeration part, the other end of the second working fluid pipe 5 extends downward, and the end of the second working fluid pipe 5 away from the first working fluid pipe 4 is connected to the refrigeration part. The first working fluid pipe 4 transmits the low-temperature working fluid vertically upward, and then inputs it into the second working fluid pipe 5, and cools the outside through the radiation plate 3. Finally, the output end of the second working fluid pipe 5 is connected to the input end of the refrigeration part, so that the working fluid that absorbs heat is absorbed by the refrigeration part, forming a cycle. This method of transporting the low-temperature working fluid allows the low-temperature working fluid to first pass through the first working fluid pipe 4, and then pass through the second working fluid pipe 5 connected to the radiation plate 3, so that the temperature of the first working fluid pipe 4 is lower than the temperature at the radiation plate 3, which is conducive to the first working fluid pipe 4 absorbing the heat radiation reflected from the radiation plate 3.

[0023] like Figure 2 As shown, further, the second working fluid tubes 5 are arranged in an S-shape. The S-shaped arrangement of the working fluid tubes can increase the contact area with the radiation plate 3, so that the second working fluid tubes 5 can transfer the coldness of the low-temperature working fluid to the radiation plate 3 more quickly.

[0024] like Figure 4 As shown, as another embodiment of the present invention, the transmission component includes: a second working fluid pipe 5 and an intermediate pipe 2, the end of the first working fluid pipe 4 away from the refrigeration part is connected to the second working fluid pipe 5, the other end of the second working fluid pipe 5 is connected to the refrigeration part, the two ends of the intermediate pipe 2 are respectively connected to the second working fluid pipe 5 and the refrigeration part, the radiation plate 3 is wrapped on the second working fluid pipe 5, and the first working fluid pipe 4 and the intermediate pipe 2 are both provided with a regulating valve 6 at one end close to the refrigeration part. By adjusting the regulating valve 6 on the first working fluid pipe 4 and the intermediate pipe 2, the flow rate of the working fluid in the first working fluid pipe 4 and the intermediate pipe 2 is changed, so as to control the flow of the first working fluid pipe 4, the intermediate pipe 2 and the second working fluid pipe 5 separately, so that the user can adjust and balance the temperature of the first working fluid pipe 4 and the radiation plate 3 as needed.

[0025] like Figure 1 As shown in Figure 4, further, it also includes: a running wheel 7 and a universal wheel 8, and the running wheel 7 and the universal wheel 8 are used to drive the refrigeration unit to move on the ground. The running wheel 7 and the universal wheel 8 are both arranged at the bottom of the box body 1, and the universal wheel 8 and the running wheel 7 form a triangular support surface to provide support force for the box body 1. A driving motor for driving the running wheel 7 to move can also be arranged at the bottom of the box body 1. When the device needs to be moved, the driving motor is started to drive the running wheel 7 to move on the ground, so that the device can be moved to the position to be used.

[0026] Furthermore, the parabolic opening of the radiation plate 3 faces the input end of the refrigeration unit, so that the high temperature working fluid generated by the radiation plate 3 can be quickly absorbed by the refrigeration unit, avoiding residual heat from affecting the refrigeration effect of the device.

[0027] like Figure 1 Or as shown in 4, further, it also includes an infrared camera 9, the infrared camera 9 is located at the top of the first working fluid tube 4, the infrared camera 9 is electrically connected to the controller 10, and the motor is also electrically connected to the controller 10. The infrared camera 9 is used to detect the amount of heat generated by the user's body and the information of the heating position, and transmit the detected information to the controller 10. After receiving the information transmitted by the infrared camera 9, the controller 10 controls the motor to drive the walking wheel 7 to move to a suitable position. The user's position is detected by the infrared camera 9, and the detected user information is transmitted to the controller 10. The controller 10 controls the motor to drive the walking wheel 7 to move to a suitable position on the ground based on the received information, so that the user can maintain a suitable cooling distance to cool the user's position during the movement. A protective cover can be set on the outside of the infrared camera 9 to protect the infrared camera 9.

[0028] Furthermore, it also includes a voice receiving module, a voice analysis module and a voice response module. The voice receiving module is used to receive the voice command information issued by the user. The voice receiving module transmits the received voice command information to the voice analysis module. The voice analysis module analyzes the voice command information and transmits the voice command to the controller 10 and the voice response module. The controller 10 performs the corresponding action, and the voice response module feeds back the execution status of the voice command to the user. When the user issues a voice command, the voice receiving module receives the voice command issued by the user, and the voice receiving module transmits the received voice information to the voice analysis module. The voice analysis module analyzes the received voice command and transmits the analysis structure to the controller 10. The controller 10 controls the various components of the device to perform corresponding actions, such as opening and closing the refrigeration unit, and the front, back, left, and right movement of the motor-driven walking wheel 77. The voice response module feeds back the operation performed by the controller 10 to the user in the form of voice broadcast.

[0029] Furthermore, a remote controller is included, and the remote controller is connected to the controller 10 via a wireless connection device. The wireless connection device between the remote controller and the controller 10 can be an infrared signal transmitting device, a Bluetooth connection, etc. The remote controller is convenient for users to manually control various components of the device to perform corresponding actions when it is inconvenient for users to use voice or the infrared camera 9 detects and recognizes inaccurately, such as controlling the box 1 to move forward or backward and controlling the opening and closing of the refrigeration unit through the remote controller.

[0030] Furthermore, the first working fluid pipe 4 is made of copper, and the radiation plate 3 is made of aluminum foil. Aluminum foil is generally silver-white, which can enhance the reflection effect of the radiation plate 3 on the heat radiation emitted by the human body. The radiation plate 3 can also be made of other metal materials.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
