Overview
The Nylon Pump-Circulation Liquid Cooling Vest is a reusable wearable cooling system developed for wholesale, OEM, team-cooling, and hot-weather work projects.
Unlike passive ice-pack vests that keep cooling packs in fixed positions, this system uses a compact electric pump to circulate cooled water through internal tubing distributed around the vest.
For preparation, users add approximately 500mL of water together with a frozen bottle, ice pack, or suitable ice source. The operating instructions use an approximately 550mL frozen water bottle as a reference cooling source.
The controller offers three circulation patterns, allowing continuous or intermittent water flow depending on the required operating pattern.
Cooling duration and pump runtime should be treated separately: cooling depends primarily on the ice-and-water preparation and environment, while the external power bank supplies electricity to the circulation pump.
Key Technical Features
Pump-Driven Water Circulation
A compact electric pump circulates cooled water through the vest’s internal tubing system.
This distributes the cooling medium around multiple areas of the garment rather than relying only on stationary cooling packs.
Tested 150–180 Minute Cooling Cycle
Under ChaoYue product-test conditions, one prepared ice-and-water setup provided approximately 150–180 minutes of cooling.
Actual cooling duration can vary with ambient temperature, cooling-source preparation, user activity, circulation mode, and other operating conditions.
Three Circulation Modes
The controller provides three operating patterns:
- Mode 1: Continuous circulation
- Mode 2: 30 seconds running / 60 seconds paused
- Mode 3: 30 seconds running / 120 seconds paused
This allows circulation frequency to be adjusted according to the application and preferred operating pattern.
12+ Hour Tested Pump Runtime
In ChaoYue testing, a 10,000mAh power bank operated the circulation pump for more than 12 hours.
This does not mean the ice-and-water system provides 12 hours of cooling. The battery powers the pump, while the cooling period depends primarily on the temperature and condition of the cooling source.
EVA / TPU Water Reservoir
The internal cooling reservoir uses EVA / TPU material and connects to the circulation system through food-grade silicone tubing.
The system can use a frozen plastic bottle, ice pack, or suitable ice source together with approximately 500mL of water.
Adjustable Wearable Structure
Adjustable shoulder and side straps provide an approximate 90–110cm waist range, allowing the vest to accommodate different body dimensions and workwear layers.
Nylon Outer Shell and Polyester Lining
The current textile structure uses:
Outer: 100% Nylon
Lining: 100% Polyester
These materials form the wearable structure around the internal reservoir, tubing, and circulation system.

Product Comparison
Active Liquid Cooling Vest vs. Passive Ice-Pack Vest
The main difference is how cooling is distributed.
A passive ice-pack vest relies on frozen packs positioned at fixed areas of the garment. The Liquid Cooling Vest uses an electric pump to circulate cooled water through internal tubing.
| Feature | Pump-Circulation Liquid Cooling Vest | Passive Ice-Pack Vest |
|---|---|---|
| Cooling Method | Pump-driven water circulation | Passive cooling packs |
| Cooling Distribution | Circulated through internal tubing | Localized around packs |
| Circulation Control | 3 selectable modes | None |
| Tested Cooling Duration | Approx. 150–180 min under test setup | Depends on pack and conditions |
| Cooling Preparation | Water + frozen bottle / ice source | Pre-frozen packs |
| Electrical Power | External USB power bank | Not required |
| Adjustment | Shoulder + side straps | Depends on model |
| Maintenance | Reservoir, tubing and pump require care | Cooling packs require refreezing |
The active liquid system therefore provides a different product category for buyers who want circulated cooling rather than fixed passive cold storage.
Ordering & Production Information
The standard vest is supplied without a power bank.
Trial-order arrangements can be discussed before larger production so buyers can evaluate:
- Cooling-system performance
- Fit and adjustment
- Product configuration
- Branding requirements
If a project requires power banks, battery supply and shipping arrangements should be confirmed separately because lithium-battery transportation involves additional logistics requirements.
Production lead time depends on order quantity, customization scope, material preparation, component requirements, and packaging. The schedule is confirmed after the final project specification is agreed.
Usage Limitations & Care
Cooling Preparation
- Open the reservoir filling port.
- Insert a frozen plastic bottle, ice pack, or suitable ice source.
- Add approximately 500mL of water.
- Secure the reservoir cap.
- Connect a compatible USB power source.
- Start the pump and select the required circulation mode.
Pump and Tubing Handling
Disconnect the power source before removing the pump.
When reinstalling the pump, the inlet and outlet tubes must be reconnected to the corresponding pump ports.
Do not forcibly remove the tubing directly from the water reservoir, as incorrect removal or reconnection may affect the internal water-routing system.
Cleaning
- Remove the power bank before cleaning.
- Remove the motor pump according to the operating instructions.
- Hand wash gently below 30°C / 86°F.
- Do not machine wash.
- Do not tumble dry.
- Allow all textile and removable components to dry completely before reassembly.
FAQ
1. How does the liquid cooling vest work?
The vest uses a compact electric pump to circulate cooled water through internal tubing distributed around the garment.
Users prepare the system with approximately 500mL of water plus a frozen bottle, ice pack, or suitable ice source. The pump then circulates the cooled water through the vest while the controller determines whether circulation runs continuously or intermittently.
2. How long does one cooling setup last, and how long does the pump run?
In ChaoYue product testing, one prepared ice-and-water setup provided approximately 150–180 minutes of cooling.
Separately, a tested 10,000mAh power bank operated the circulation pump for more than 12 hours.
These are two different measurements: cooling duration depends primarily on the ice-and-water system, while electrical runtime describes how long the battery can power the pump.
3. What are the three circulation modes?
The current controller provides:
Mode 1: Continuous circulation
Mode 2: 30 seconds running / 60 seconds paused
Mode 3: 30 seconds running / 120 seconds paused
The modes allow buyers and end users to select different circulation patterns according to operating conditions and preference.
4. What cooling source and power supply does the vest require?
The reservoir can be prepared with a frozen plastic bottle, ice pack, or suitable ice source together with approximately 500mL of water. The operating instructions use an approximately 550mL frozen bottle as a reference.
The pump requires an external USB power source. A power bank is not included with the standard vest.
5. Can the Liquid Cooling Vest be customized for OEM projects?
Yes. As a functional cooling product, the current OEM MOQ is 500 pieces.
OEM projects can discuss logos, colors, packaging, labels, manuals, materials, strap and fit changes, component configurations, and other project-specific adaptations. Structural or functional modifications should be reviewed before sampling.
