Description

Technical Field

[0001] This utility model relates to the field of tent technology, specifically to a tent with active cooling function and its cooling system. Background Technology

[0002] Tents are essential equipment for outdoor camping and fieldwork, providing users with a resting space that shelters them from wind and rain.

[0003] However, existing tents generally lack active temperature regulation. In strong sunlight or humid weather, heat accumulates rapidly inside the tent due to the greenhouse effect, causing the internal temperature to be much higher than the external environment, resulting in stuffiness and discomfort, which seriously affects the user's rest quality and health.

[0004] Currently, to solve this problem, users can usually only use physical ventilation (opening doors and windows) or handheld fans. These methods are not very effective in windless or high temperature and humidity environments and cannot achieve real cooling.

[0005] Using traditional compressor-based air conditioners in tents presents significant obstacles: they are bulky and heavy, consume extremely high power (requiring large generators), are expensive, and lack portability. Therefore, the market has long lacked a solution specifically designed for tents that balances efficient cooling, portability, low power consumption, and reasonable cost.

[0006] Therefore, we need to propose a tent with active cooling function and its cooling system, and design a modular active cooling device for the tent to efficiently reduce the temperature inside the tent, while also having the advantages of portability, low noise, and low power consumption. Utility Model Content

A Peltier serving as a core heat pump element is provided between the hot end component and the cold end component. The hot end component is responsible for dissipating the heat generated by the Peltier to the outside of the tent body, while the cold end component is responsible for dissipating the low temperature generated by the Peltier to the inside of the tent body.

[0009] Preferably, a curtain for sealing the window is provided on the main body of the tent near the upper edge of the window. A Velcro closure is installed on one outer edge of the curtain, and a Velcro closure is installed on the outer perimeter of the window.

[0013] This utility model also provides a refrigeration system installed on a tent with active refrigeration function as described above. The system includes a controller, a portable power supply module, and a motor drive module that drives the hot-end fan and cold-end fan in the refrigeration equipment. The power supply module and the motor drive module are both electrically connected to the controller, and the power supply module is electrically connected to the motor drive module. The controller and the power supply module are both electrically connected to Peltier.

A diode D30 is connected between pin 1 of connector P4 and pin 4 of power chip U20. A resistor R7 is connected between pin 2 of connector P4 and the gate of MOSFET Q10.

[0015] Preferably, resistors R2 and R30 are connected to pin 6 of the power chip U20. One end of resistor R2 is connected to the drain of MOSFET Q10, and one end of resistor R30 is connected to the source of MOSFET Q10 and pin 2 of the power chip U20. Resistor R1, light-emitting diode D10, and resistor R60 form a closed loop between pins 1 and 5 of the power chip U20.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a truly effective "air conditioning" system for tents by adding a refrigeration device. Cold air is blown into the tent body from the cold air outlet inside the tent, and after absorbing heat in the tent body, it is drawn back and cooled from the return air inlet inside the tent, forming a closed internal air circulation inside the tent, which has high cooling efficiency. The heat generated by the refrigeration device is directly discharged to the outside of the tent body through the hot air outlet through the hot end air duct, without affecting the internal temperature of the tent body, breaking the inherent stuffy situation inside the tent.

[0019] 2. This utility model features a window on the tent, with the refrigeration equipment installed at the window location, making it convenient to install the refrigeration equipment on the tent. Furthermore, installing the refrigeration equipment on the tent can significantly enhance the outdoor experience, allowing users to enjoy a cool and comfortable resting environment even in the hot outdoors, thus expanding the seasonal and geographical scope of camping activities.

[0020] 3. The power supply module design provides a large current to the motor, which can be applied to high-power fan motors. It also avoids voltage fluctuations and noise interference caused by drastic changes in motor load, thus improving the stability of the refrigeration equipment. The motor drive module design allows for rapid charging and discharging of the gate capacitance of the MOSFET, shortening the switching time of the MOSFET and the time it spends in a semi-conducting state during turn-on and turn-off. This results in less heat loss and increases the operating efficiency of the refrigeration equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a tent with active cooling function, including a tent body 1 and a cooling device 3 installed on the tent body 1. The cooling device 3 can be quickly and conveniently installed on various tents, effectively reducing the temperature inside the tent, and has the advantages of being portable, low-noise, and low-power consumption, significantly improving the comfort of outdoor living.

[0025] The tent body 1 has a window 4 for installing the refrigeration equipment 3. Furthermore, a U-shaped mounting base is installed around the window 4 to enhance the stability of the window 4 and facilitate the installation of the refrigeration equipment 3 at the window 4 position via the mounting base. The refrigeration equipment 3 includes a heat insulation plate 31 bonded to the window 4 (i.e., the mounting base). The heat insulation plate 31 is filled with heat insulation materials such as polyurethane foam, glass wool or epoxy resin potting compound, which effectively blocks radial heat conduction between the hot and cold ends and ensures that the refrigeration efficiency is not lost.

[0026] A hot end component located outside the tent body 1 is installed on one side of the heat insulation plate 31, and a cold end component located inside the tent body 1 is installed on the other side of the heat insulation plate 31. A Peltier 37 serving as a core heat pump element is provided between the hot end component and the cold end component. The hot end component is responsible for dissipating the heat generated by the Peltier 37 to the outside of the tent body 1, and the cold end component is responsible for dissipating the low temperature generated by the Peltier 37 to the inside of the tent body 1.

[0027] By coordinating the hot-end components, cold-end components, and Peltier 37, it is ensured that cold air inside the tent body 1 does not leak out and hot air outside the tent body 1 does not flow in.

[0028] A curtain 2 for sealing the window 4 is provided on the main body 1 of the tent near the upper edge of the window 4. A Velcro 11 is installed on one outer edge of the curtain 2, and a Velcro 21 is installed around the window 4. When the cooling device 3 is not in use, the Velcro 11 and Velcro 21 are bonded together. The bonding method between the Velcro 11 and Velcro 21 is not limited; optionally, the rough side of the Velcro 11 can be bonded to the hook side of the Velcro 21.

[0029] The heat insulation plate 31 has a Velcro 32 installed on one outer ring. When the refrigeration equipment 3 is in use, the Velcro 32 is bonded to the Velcro 21. Optionally, the rough side of the Velcro 32 is bonded to the hook side of the Velcro 21.

[0030] The cold end component includes a cold end heat sink 36, a cold end fan 35 is mounted on one side of the cold end heat sink 36, and the other side of the cold end heat sink 36 is tightly attached to the cold end of the Peltier 37 by thermal grease.

[0031] The cold end heat sink 36 is a finned heat sink made of aluminum or copper with a high thermal conductivity. It is tightly attached to the cold end of the Peltier 37 with a layer of high-performance thermally conductive silicone grease for efficient absorption and diffusion of cold energy.

[0032] The cold-end fan 35 is a centrifugal turbine fan or a low-noise axial fan, located on one side of the cold-end heatsink 36, used to drive air to flow at high speed over the fins of the cold-end heatsink 36, forcing convection to maximize heat exchange efficiency.

[0033] The hot end component includes a hot end heat sink 34, a hot end fan 33 is mounted on one side of the hot end heat sink 34, and the other side of the hot end heat sink 34 is tightly attached to the hot end of a Peltier 37 with thermal grease.

[0034] The hot-end heat sink 34 is a larger aluminum or copper finned heat sink with a larger heat dissipation area than the cold-end heat sink 36. It is tightly attached to the hot end of the Peltier 37 with thermal grease to efficiently dissipate the heat pumped heat.

[0035] The hot-end fan 33 is an axial fan with high air pressure, located on one side of the hot-end heat sink 34, to generate a strong directional airflow.

[0036] It is worth noting that this tent also includes an outer shell (not shown in the figure) for mounting the refrigeration equipment 3. The outer shell is equipped with a cold air outlet, a return air outlet, a hot air outlet, and a power interface for connecting the power supply module. The internal circuitry of the power interface supports a wide DC voltage input of 12V / 24V for connecting to various power sources.

[0037] Furthermore, the interior of the casing is equipped with independent cold-end air ducts and hot-end air ducts; The cold-end air duct provides a closed cold air circulation path, so that the cold air circulates only inside the tent body 1 and is isolated from the external environment; the hot-end air duct forms an independent, short-circuited and efficient hot air exhaust path. External ambient air is drawn in, flows through the hot-end radiator 34, absorbs heat and becomes hot air, and is directly discharged from the hot air exhaust outlet to the outside of the tent body 1, so as to ensure that the heat is quickly and thoroughly discharged to the external environment and prevent the impact of heat backflow on the cold-end components.

[0038] Specifically, during the internal circulation: cold air is blown into the tent body 1 from the internal cold air outlet, and after absorbing heat within the tent body 1, it is drawn back and cooled from the internal return air inlet, forming a closed internal air circulation within the tent, which has high cooling efficiency. When the heat is exhausted outside the tent, the heat generated by the cooling equipment 3 is discharged directly to the outside of the tent body 1 through the hot air duct and the hot air outlet, without affecting the internal temperature of the tent body 1.

[0039] Please see Figure 6-8 This utility model also provides a refrigeration system installed on a tent with active refrigeration function as described above. The system includes a controller, a portable power supply module, and a motor drive module that drives the hot-end fan 33 and the cold-end fan 35 in the refrigeration device 3. The power supply module and the motor drive module are electrically connected to the controller and the motor drive module, respectively. The controller and the power supply module are also electrically connected to the Peltier 37.

[0040] The power supply module uses a portable power bank, a tent-specific solar panel, or a small silent generator to drive the refrigeration equipment 3 for extended periods, thus solving outdoor power needs.

[0041] The power supply module includes a power chip U20, connector P3, connector P4, and MOSFET Q10. A diode D20 is connected between pin 1 of connector P3 and pin 4 of power chip U20. A diode D30 is connected between pin 1 of connector P4 and pin 4 of power chip U20. A resistor R7 is connected between pin 2 of connector P4 and the gate of MOSFET Q10.

[0042] Diodes D20 and D30 are reverse-current protection diodes.

[0043] Resistors R2 and R30 are connected to pin 6 of the power chip U20. One end of resistor R2 is connected to the drain of MOSFET Q10, and one end of resistor R30 is connected to the source of MOSFET Q10 and pin 2 of the power chip U20. Resistors R1, LED D10, and resistor R60 form a closed loop between pins 1 and 5 of the power chip U20.

[0044] Resistor R1 is the charging current setting resistor, and resistor R60 is used to connect the status indicator (LED D10) as a current limiting resistor. LED D10 is a bicolor LED used to display the charging status.

[0045] Capacitor C30 is an input decoupling capacitor used to filter out high-frequency noise and ripple from the power supply, providing a stable and clean operating voltage for the power chip U20, and improving the circuit's anti-interference capability and stability.

[0046] The motor drive module includes a gate driver U2, a MOSFET Q1, and a MOSFET Q2. Pin 1 of the gate driver U2 is connected to a 15V voltage. Pin 2 of the gate driver U2 is connected to a resistor R9 for receiving PWM signals. Pin 3 of the gate driver U2 is connected to a resistor R10. The source of the MOSFET Q1 and the drain of the MOSFET Q2 are connected and connected to pin 6 of the gate driver U2.

[0047] A resistor R13, a resistor R14, and a diode D6 form a closed loop between pin 5 of the gate driver U2 and the gate of the MOSFET Q2. A resistor R3, a resistor R6, and a diode D1 form a closed loop between pin 7 of the gate driver U2 and the gate of the MOSFET Q1. A capacitor C3 and a capacitor C4 are connected in parallel between pin 8 of the gate driver U2. A diode D2 and a capacitor C2 are connected in series between the terminals of capacitors C3 and C4.

[0048] Gate driver U2 receives a weak PWM signal from the controller, amplifies it, and provides a sufficiently large current and voltage to quickly turn on and off the two high-power MOSFETs Q1 and Q2.

[0049] MOSFETs Q1 and Q2 are the actuators or switches of the motor drive module. Under the control of the gate driver U2, they alternately turn on and off, converting DC power into a high-frequency square wave voltage and outputting it to drive the motor of the hot-end / cold-end fan 35.

[0050] Diode D2 and capacitor C3 form a bootstrap circuit. Resistor R3 is the current-limiting resistor for the gate of MOSFET Q1, and resistor R13 is the current-limiting resistor for the gate of MOSFET Q2. Resistor R15 is connected to the source of MOSFET Q2; R15 is a power resistor used for driving the circuit and can be replaced with a higher-power resistor under heavy loads to prevent excessive current from burning out the resistor. Resistors R9 and R10 are current-limiting resistors connecting the controller pins to the gate driver U2.
