The invention discloses a power battery thermal management system with functions of efficient heat dissipation and efficient heating. The power battery thermal management system comprises a power battery case and a thermal management system, wherein a plurality of battery monomers are adjacently aligned to form a battery pack placed inside a battery case housing, a composite phase change material plate is sandwiched between the gap of the adjacent batteries and the surface of the outermost side battery in the battery pack width direction, the composite phase change material plates and thermal pipes are combined to form composite phase change material thermal pipe coupling components, the composite phase change material thermal pipe coupling components are additionally arranged on both sides of the battery pack, the thermal pipes extends from the through holes on the battery module housing, the extending ends are connected to heating devices and heat dissipation fans, and a programmable automatic temperature regulator treats the signal from a temperature sensor by programming so as to determine whether the fans and the heating devices are started. The power battery thermal management system of the present invention has advantages of simple and firm whole structure, high efficiency, stable operating, and the like. In addition, the battery pack can be subjected to direct, unified and uniform cooling and heating, such that the battery can work at the appropriate temperature range, and the electric vehicle battery thermal management system is improved.

A fast-cooking table top oven has a. a housing with four sides, a base and a top, one side being the front of the oven, a portion of the front being capable of opening as a door, and another side being the back of the oven; b. a first heating element capable of keeping the housing at over 700° F., the first heating element being situated in the base of the housing; c. a deck that sits on the base of the housing and above the first heating element, the deck being suitable for cooking a food; d. a thermostat for monitoring the temperature of the inside of the housing; e. a second heating element situated in the top of the housing, suitable for browning a top surface of the food; f. a button situated on the front side of the housing next to the door; and g. a controller connected to the thermostat, the first heating element, the second heating element, the thermostat, and a button situated on the front side of the housing, whereby the controller maintains the temperature within the housing using the thermostat by directing power to the first heating element, until the button is actuated, t which time it transfers power to the second heating element such that the second heating element rapidly heats up and thereby promptly cooks a food. Also disclosed is a quick-browning method to be performed at over 600° F.

The invention relates to an engine power system, and aims to provide a pneumatic and internal combustion hybrid system based on multi-stage utilization of afterheat of cooled water. According to the system, an air inlet pressure stabilization box of a pneumatic engine is connected with an air storage tank through a high pressure air pipeline; an air cylinder body and an air cylinder cover of a water-cooled internal combustion engine, a water pump and a pipeline form loop circulation; a circulation loop of the cooling water in the water-cooled internal combustion engine is divided into three stages; the first stage of the circulation loop is small circulation of the internal combustion engine body; the second stage of the circulation loop and the third stage of the circulation loop are respectively added into a pneumatic engine air cylinder and a water and air heat exchanger; and the stages of circulation loops are switched by turning on and turning off an electronic thermostat. The system makes full use of the afterheat of the cooling water in the internal combustion engine, so that the working environment of the pneumatic engine is improved, the circulation output power of the pneumatic engine is improved effectively, and the air consumption rate of the pneumatic engine is reduced finally; furthermore, the energy consumption of the internal combustion engine is reduced; and the dynamic property and the economy of the power system are improved.

The invention relates to an on-line colorimetric pH measuring instrument for water vapor detection of a power plant, and belongs to a water quality chemical analysis instrument. The instrument comprises a multi-path sample injection valve, an overflow device, a water shortage detection device, a channel selection valve, a peristaltic metering pump I, a peristaltic metering pump II, a mixer, an automatic thermostat, a photometer, a pH 6.86 standard liquid barrel, a pH 9.18 standard liquid barrel, a pH 10.0 standard liquid barrel and a phenolphthalein indicator barrel. The instrument has the advantages that the non-traditional glass electrode is used as the pH sensor, the glass electrode and corresponding accuracy influence factors are eliminated, the photometer with high stability and accuracy is used for measurement, the measurement accuracy and reliability are greatly improved, the workload of instrument maintenance personnel is reduced, and the method is a novel method for online measurement of the pH of a steam-water system of a power plant. According to the characteristic of slow change of water quality pH of a power plant, time-sharing measurement of more paths of water samples can be expanded.
