Embodiment Construction

[0009] The implementation of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings. as attached figure 1 , 2 , 3, 4, 5, 6, 7, and 8, this invention is a device for heating and cooling flowing liquid, which uses semiconductor refrigeration chips to heat the heating plate, and then transfers heat to the flowing liquid in the metal hose for indirect heating The method is to increase the flow path of the liquid in the heating device through the return pipeline, and prolong the flow time of the liquid in the heating device. It mainly includes three heating plates, a metal hose, four semiconductor cooling fins, four radiators, two heat insulation boards, four heat insulation brackets and four fans.

[0010] The front heating plate 4, the middle heating plate 6 and the rear heating plate 7 are three rectangular parallelepiped copper plates stacked together successively with the same external dimensions. One si...

Abstract

The invention relates to a device for heating and refrigerating flowing liquid, and belongs to the field of temperature control systems. The device adopts a double-layer loop-shaped passage to heat or refrigerate the flowing liquid; the device is provided with a front heating plate, a rear heating plate and a middle heating plate which have the same shape and dimension; the middle heating plate is a rectangular plate; one side of the rectangular plate is processed with a front loop-shaped groove of the middle heating plate with a semicircular cross section; and the other side of the rectangular plate is processed with a rear loop-shaped groove of the middle heating plate with a semicircular cross section. The contact faces of the front heating plate and the rear heating plate towards the middle heating plate are processed with a loop-shaped groove of the front heating plate with a semicircular cross section and a loop-shaped groove of the rear heating plate with a semicircular cross section respectively; and metal hoses are positioned in the loop-shaped grooves to form the double-layer loop passage. The lateral surface of the heating plate is stuck with four semiconductor refrigerating sheets; and by heating of the heating plate, the temperature of the flowing liquid is indirectly controlled. The device has a simple structure, has no problem of liquid sealing, is convenient to maintain and realizes even and rapid heating and refrigeration of the flowing liquid.

Description

technical field [0001] The invention relates to a device for heating and cooling flowing liquid, which belongs to the field of temperature control systems, in particular to a device for rapidly heating and cooling the temperature of flowing liquid. Background technique [0002] A direct liquid fuel cell is a power generation device that directly converts chemical energy stored in liquid fuels and oxidants into electrical energy efficiently and without pollution. It is considered as an ideal power source for portable electronic devices due to its outstanding advantages such as high efficiency, environmental protection, high energy density, and convenient storage and portability, and has received more and more attention. [0003] Fuel cell technology is in the research and development stage, and the main factors affecting the practical application of direct liquid fuel cells are: low performance-price ratio, unsatisfactory reliability and stability of long-term operation. Fac...
