Embodiment Construction

[0036] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-8 :

[0037] A fluid heat exchanger, comprising a plate heater 1, the plate heater 1 includes a ceramic substrate, a heating resistor and an electrode, the ceramic substrate is arranged in a double-layer structure, and the resistor is printed on two layers in the form of a pattern Between the ceramic substrates, and electrically connected to the power supply through electrodes, the upper and lower surfaces of the plate heater 1 form a heat transfer surface, and a pair of deflectors 2 made of elastic materials are arranged on the upper and lower sides of the plate heater 1. The elastic material adopts a material that has elasticity and can form a good sealing structure, such as elastic plastic or rubber, preferably rubber, and a fluid channel 3 is formed between the inner wall of the deflector 2 and the heat transfer surface of the plate...

Abstract

The invention belongs to the technical field of heat exchangers, and relates to a fluid heat exchanger. The fluid heat exchanger comprises a plate type heater, the plate type heater comprises a ceramic base body, a heating resistor body and an electrode, the upper surface and the lower surface of the plate type heater form a heat transfer surface, a pair of flow guide plates made of elastic materials are arranged on the upper side and the lower side of the plate type heater, a fluid channel is formed between the inner wall of the flow guide plate and the heat transfer surface of the plate type heater, and the flow guide plate is covered with a shell which is used for pressing the flow guide plate and enabling the flow guide plate to be hermetically connected with the heat transfer surface of the plate type heater. The fluid heat exchanger has better sealing performance and heat exchange efficiency.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and relates to a fluid heat exchanger. Background technique [0002] The sanitation washing device is provided with a heat exchanger for making washing water an appropriate temperature when washing a part of a human body after defecating with water. There are various types of such heat exchangers, and one of them is a plate-type heat exchanger disclosed in Patent Document 1. The flat-plate heat exchanger has the following structure: the flat-shaped heater is erected and stored in a rectangular parallelepiped-shaped housing with a small width, and the two heat transfer surfaces of the flat-shaped heater are respectively Two flow paths are formed, and the two flow paths face upward while zigzagging in the horizontal direction. Then, the temperature of the washing water is raised to an appropriate temperature by allowing the washing water to flow along the respective flow paths while the f...
