A device for extracting thermal energy from the core body of an individual via the palm thereof during or after physical exertion activity by that individual, wherein the device includes (a) an enclosure containing a cold-maintaining substance, wherein the enclosure is not larger than the palm; and (b) securing means attached to the enclosure for securing the enclosure against the palm.

In a projector assembly having a lamp for emitting light, and an ellipsoid reflector for capturing the light, the ellipsoid reflector having an opening through its vertex facilitating placement of the lamp, there is provided an improvement wherein the opening in the ellipsoid reflector is sized to allow a major portion of cooling air to pass therethrough into a region defined by the ellipsoid reflector. An air deflector is situated in the opening so as to facilitate distribution of cooling air along the lamp and outwardly towards the inside surface of said ellipsoid reflector from within said region.

A cooling device for use in an electric arc furnace is provided. The cooling device provides a novel and effective method for cooling burners, lances, enclosures, and other devices used in high heat environments, such as in Electric Arc Furnaces. According to one aspect of the invention used in a steel making process in an electric arc furnace, a cooling tube is inserted into a cooling cavity in a burner. Cooling fluid is injected through the cooling tube into the cavity to cool the portions of the burner adjacent the cooling cavity. The cooling fluid is then extracted from the cavity through a concentric space between the cooling tube and the cooling cavity. According to another aspect of the present invention, a cooling fluid distribution flange is provided to distribute cooling fluid to a plurality of cooling tubes to inject cooling fluid into a plurality of associated cooling cavities.

Accurate measurement and monitoring of a computer room air conditioning unit's cooling production, distribution, and consumption is necessary to optimize effectiveness and efficiency and minimize redundancy. A mass air flow monitoring device comprises an array of sensor modules and a controller module with display, user interface, and I / O for third party connectivity. The device monitors temperature, pressure, water content, and quantity of airflow in a CRAC's supply air stream and return air stream and compares the two measurements to determine the amount of energy, or enthalpy, put into or taken out of the air. The result, displayed in watts, allows for the efficient control of production, distribution, and usage of supply air from the CRAC unit. Over or under provisioning can be quickly identified and corrected and, when used in conjunction with power consumption monitoring, a “watts of cooling for watts of power consumption” efficiency metric can be provided.

The invention discloses a shell structure of an electroacoustic alarm controller terminal, which comprises a lower shell, and an upper shell in sliding connection with the lower shell is sleeved outside the lower shell; four locking buffer mechanisms; the locking buffer mechanism comprises a fixing box fixed to the lower shell, a sliding block capable of resetting is slidably connected into the fixing box, the lock rod penetrates through the upper shell and is slidably connected with the upper shell, a strip-shaped groove is formed in the lower shell in a penetrating mode, the lock rod is slidably connected into the strip-shaped groove, a sleeve is fixedly connected to the inner bottom of the strip-shaped groove, and the sleeve is fixedly connected to the inner bottom of the strip-shaped groove. A short rod is slidably connected into the sleeve, and a buffer block is fixed to the upper end of the short rod. Through cooperation of the lock rod, the buffer block and the first spring, the upper shell impacted by an object can be buffered, the upper shell is protected, meanwhile, the upper shell can be taken down conveniently, operation is easy and convenient, and effective heat dissipation can be conducted on the interior of the upper shell and the interior of the lower shell.

The invention discloses a battery case with automatic heat dissipation function, comprising a heat dissipation base, a case body is installed on the heat dissipation base, and three first-stage heat exchange tubes arranged separately are installed in the case body, three The first-stage heat exchange tubes are connected through first-stage connecting tubes, three second-stage heat exchange tubes are installed in the box, and the second-stage heat exchange tubes are connected through second-stage connecting tubes. The inner wall of the box is fixedly connected with a first hollow cylinder, a first spring is fixed between the first piston and the inner top of the first hollow cylinder, and the first-stage heat exchange tubes and the second-stage heat exchange tubes pass through respectively The first short tube and the second short tube communicate with the first hollow cylinder. The invention can not only perform frequency conversion processing on the water pump to realize heat exchange and heat dissipation of the heat in the box, but also reduce the loss of electric power. Quickly extinguish open fires.
