Description

Cold of semiconductor pathology paraffin embedding
Technical field:The utility model belongs to technical field of medical instruments, is specifically related to cold of a kind of semiconductor pathology paraffin embedding.
Background technology:Requirement to cold of pathology paraffin embedding in the practical application is: the one, and refrigerating speed is fast, stable performance, safeguards simple; Have round-the-clock ability to work, also can drop to the temperature that needs to temperature under the hot environment; The 2nd, in light weight, remainder is littler except that using volume; The Three Greens colour circle is protected.
The cold Daepori of existing pathology paraffin embedding is all over adopting compressor cooling, and noise is big; Need to add cold-producing medium, contaminated environment; Refrigerating speed is slow, environment temperature poor refrigerating efficiency during greater than 27 ℃; Owing to be subjected to the restriction of actual request for utilization, the volume that pathology is cold is unsuitable excessive, weight can not be overweight, thereby cold employed refrigeration compressor of traditional pathology must be " microminiaturization ", " microminiaturization " though the compressor volume little, in light weight, but the ability of its durability and continuous working also just greatly reduces, cold failure rate height of this just traditional pathology paraffin embedding, life-span weak point, the main cause that refrigerating speed is slow, maintenance is complicated.
Summary of the invention:The purpose of this utility model is exactly the problem at existing cold existence of pathology paraffin embedding, and cold of a kind of efficient, stable, easy to use semiconductor pathology paraffin embedding is provided.
The utility model adopts following technical scheme: cold of semiconductor pathology paraffin embedding is made up of temperature controller, temperature sensor, relay, water of radiation row, water row heat emission fan, water pump, direct-current switch power supply, conduction cooling sheet metal, semiconductor chilling plate, water-cooling plate.Being the conduction cooling sheet metal above the semiconductor chilling plate, is water-cooling plate below, and temperature sensor is installed on the conduction cooling sheet metal; Water-cooling plate, water of radiation row, water row heat emission fan, water pump combine the composition hydrologic cycle cooling system, and water pump pipeline connects with water of radiation row, water-cooling plate; Cold of semiconductor pathology paraffin embedding is carried out temperature controlling by the temperature control system of being made up of temperature controller, temperature sensor, relay, direct-current switch power supply.
Principle of work of the present utility model is: energising back semiconductor chilling plate is started working, and will produce transfer of heat between the semiconductor chilling plate both ends of the surface, and heat will be transferred to the other end from an end face, forms hot and cold end face thereby produce the temperature difference; The cold junction face of semiconductor chilling plate contacts with the conduction cooling sheet metal, and the temperature of sheet metal is reduced; And the heat of hot junction face dissipates heat with the continuous working of assurance semiconductor chilling plate by hydrologic cycle cooling system, thereby makes the cold junction face reach lower temperature.The temperature sensor of conduction cooling metal sheet surface is passed to temperature control system in real time to its temperature, when temperature reaches the temperature of setting, temperature control system promptly stops to power to semiconductor chilling plate, in order to avoid the temperature of conduction cooling sheet metal continues to reduce, the temperature of conduction cooling sheet metal can raise gradually after stopping power supply, and at this moment, temperature control system is powered to semiconductor chilling plate again, so go round and begin again, keep the constant of conduction cooling sheet metal temperature.
The utility model beneficial effect is: used semiconductor refrigerating technology, had refrigeration rapidly, stable performance under the hot environment, the characteristics that maintaining is simple, the life-span is long.Because do not need compressor, so without any need for cold-producing medium, but continuous working does not have environmental pollution, has wide commercial applications prospect.
